What to do if your phone screen goes blank
First of all, every owner of a mobile gadget should know that the dimming screen was already initially provided by the manufacturer only in order to save battery power in the sense that when the phone is not in use, the glowing screen is, in general, not needed. The easiest way to solve the problem is to simply set the timeout, the function of which can be found in the settings menu of the main screen and set the desired period of time, after which the screen will turn off.
When it comes to the question of what to do if the phone screen goes blank, there can be any number of reasons. The most common thing is the usual battery drain, which can be solved by connecting the phone to the mains. However, sometimes slightly different situations may occur, which imply a crash in the operation of the software system. In this case, the simplest and most recommended way to troubleshoot problems is to simply reboot the mobile gadget. In other words, you just need to turn off and then turn on the device again. In most cases this helps.
In some cases, the home screen turning off may be due to a weak processor. This reason is more typical for smartphones. But there’s nothing you can do about it, since replacing the processor even in a specialized workshop will not be easy. Besides, the smartphone is not designed for this. In addition, you need to know what to do if the phone screen goes blank if the battery itself breaks down. It’s no secret that batteries tend to fail over time. Here you just need to replace the battery with a new one, and after replacing, as on a new phone, it is recommended to use the gadget at least three times until the battery is completely discharged and then recharged. If this is not observed, no manufacturer will give a guarantee that the battery will hold a charge within the stated time frame.
In principle, if these tips do not help, then it is definitely better to contact a phone repair service center, and under no circumstances attempt repairs yourself, and even without the necessary equipment for testing faults.
Spontaneous shutdown of a smartphone is a common problem that gadget owners regularly face. There are quite a few reasons why the phone suddenly turns off by itself. In this article we will look at the most popular of them.
When the phone turns off on its own, it creates some discomfort and interferes with normal work and communication. Most often, owners of old equipment encounter this situation, but in some cases problems can also occur with new devices.
If such a problem is one-time in nature, do not panic. The reason why Android turns off may be a simple glitch in the system. But, if it is of a regular nature, it is recommended to take the gadget to a service center.
However, some tasks can be dealt with at home. You will find complete instructions for problems of various origins below.
Power key doesn't work
Mechanical malfunctions of the power button often cause the phone to turn itself off.
It is impossible to replace the key yourself at home. If such a situation occurs with a new gadget, there is a manufacturing defect. When you contact the warranty service, the equipment will either be repaired or replaced with a new one.
But sometimes the breakdown of the power button is preceded by bumps and falls. Modern smartphones are quite fragile, and even a small impact on the ground can lead to malfunctions and malfunctions. The solution is the same - contact the service center to replace the power off key.
You can also diagnose the problem at home. You need to simultaneously hold down several combinations (for example, volume rocker and mute) and look at the result. If it does not respond properly, then repair is needed.
Software failure
Another option - the brightest for most equipment owners - is a failure in the operating system. Errors in its operation may result in the cell phone freezing when performing a certain task and the inability to turn it off (or reboot) in the standard way. You can try to manually remove the battery and turn it on again. However, this method should not be abused.
Battery
If the phone constantly turns itself off, does not hold a charge and charges slowly, there is only one way out - install another battery.
Of course, you can extend the life of an old battery by several days by controlling the background mode and downloading several special programs, but this will not fix the battery.
Moreover, a swollen or mechanically damaged battery can be life-threatening. There are cases when a faulty battery caught fire simply in the hands of users, or near their faces, causing serious burns.
Therefore, you should not delay replacing the battery. This will not only affect the comfort and performance of the device, but will also protect you from health risks.
Oxidation of contacts
Even those who carefully and carefully handle their smartphones are not immune from another type of mechanical damage - oxidation of contacts on the motherboard.
Moisture can get onto contacts and junctions as follows:
- When there is a sudden change in temperature (condensation occurs).
- Frequently carrying equipment in hands in hot weather.
- Getting caught in the rain.
- Falling into a container of water.
- And others.
Modern top models are already equipped with moisture resistance, but budget cell phones do not yet have such a function. Moisture penetrates the phone through connectors, seams and speakers, becoming a catalyst for oxidative processes.
As in previous cases, this problem cannot be dealt with manually, and it is recommended to have the phone repaired by specialists.
Removing unnecessary things from the system
Android is positioned as an open platform, so each user can personalize it to suit their tastes and needs. Most often this happens by downloading software from the Play Market.
Sometimes these are several applications, and sometimes their number reaches such proportions that the equipment simply cannot cope with the processor load and constantly turns off.
The solution in this case will be as follows:
- Check the authenticity of the operating system. Only installing a licensed Android OS guarantees that the smartphone will cope with the assigned tasks properly.
- Clear your storage of unnecessary programs. Optimal loading – up to 15 different applications.
- Check whether the installed utility conflicts with the OS. You can find out this on the forums, or in reviews directly under the program page in the Play Market.
Screen breakage
Sometimes a broken screen is mistakenly perceived as a cell phone refusing to turn on. It is caused by problems with the hardware, which are usually preceded by falls or contact of the device with water.
On most gadgets, a reboot is accompanied by a slight vibration response, which can be felt even if the screen does not show signs of life. It’s worth checking for a response; if not, take it to the specialist.
Mechanical damage
Various types of “flights” are a real disaster for fragile devices. In most cases, they are brought to the service center after a fall.
You can check the malfunction yourself by slightly bending the smartphone in your hands. If it turns off, then repairs cannot be avoided.
If after an impact the back cover in the area of the camera or battery begins to heat up, then most likely the root of the problem lies in the lag of the thermal pad. It is possible to give final conclusions only after disassembling the gadget.
Moral deterioration
The average service life of a cell phone is 3-5 years, provided there are no breakdowns and care is taken. But many people use them much longer, so over time they have to visit repair points more and more often.
Equipment needs to be regularly changed and updated, because it is already difficult to get spare parts for devices that were released 5-6 years ago. And some malfunctions of outdated models are even refused to be repaired.
Therefore, when purchasing, pay attention to the OS version - if it is lower than 4.4, then maintenance will be in question.
Working in the cold
It is not recommended to expose gadgets to temperature fluctuations - this affects the battery. When working in the cold, many devices refuse to work and turn off on their own - this is normal practice. The range of suitable temperatures is indicated in the User's Manual.
Memory card
If, when installing a memory card, the smartphone does not work well, is glitchy, or turns off completely, it must be removed and replaced with another one.
Let's look at the reasons why MicroSD may conflict with the OS:
- Speed class incompatibility.
- Factory defect in the memory card.
- Mechanical damage to the slot that slows down its operation.
How to Set Windows 10 Screen Timeout
In the Windows 10 operating system, the wait period before turning off the monitor to save power is usually 10 minutes. In addition, when the monitor turns off, the computer locks. Further work is possible only after entering the password for the user login used. And if on PCs used as workstations in large companies and in production this is a necessary measure due to security requirements, then on ordinary home computers there is no need for this. Moreover, this mechanism becomes very inconvenient: I went into the kitchen for coffee and the operating system was blocked. To customize power saving and adjust the screen shutdown time in Windows 10, you need to open the power options. To do this, press the Win+R key combination and write the command powercfg.cpl. Like this:
You should see a window like this, from which you can configure the computer's power management schemes:
The power supply system that is currently used by Windows 10 will be highlighted in bold. To enter its configuration, you need to click on the link “Setting up the power supply scheme”.
The next window separately displays the parameters for putting the display into sleep mode. The line “Turn off the display” will contain the timeout that is currently used in the circuit. To configure the Windows screen timeout, simply click on the down arrow and a drop-down list will appear with all possible values. You can set it to half an hour, an hour, or even disable this function to remove the display from turning off completely. Don't forget to click the "Save Changes" button to apply the selected timeout value.

Your smartphone may not show signs of life for a variety of reasons, but mainly there are three:
- Smartphone battery is faulty or not charged
- Hardware faulty
- Your device's firmware or bootloader is faulty
None of these reasons is a reason to write off your favorite device forever. All possible problems that may arise are solvable. There are methods for self-diagnosis of a faulty device that even a schoolchild can do.
So, diagnostics:
- The first thing you need to do is check the battery charge of your device. To do this, connect your smartphone to the power supply and do nothing while waiting for the indication on the screen. If the indication does not appear within 5-10 minutes, the phone screen does not turn on, hold down the power key and try starting the phone. Turns on - great. If the problem persists, go to step 2.
- Now you need to check the functionality of the device hardware. To do this, take a USB cable, connect it first to your smartphone and then to your computer. Now watch the reaction of the latter - whether new connected devices are displayed, whether they are detected and how correctly. Experiment with the battery - try connecting your smartphone to a computer with a battery inside, as well as without it.
- Another way to check is to leave the device with the battery inside charging from the computer port for an hour or two, periodically monitoring whether it starts to overheat. Such soft charging with low current is often a panacea for the problem when the phone screen simply does not turn on. Thanks to the low charging current, the battery charges much more gently and in some cases its functionality can be restored. If no new icons appear in Device Manager, move on to step 3.
- Now let's check the phone's battery for functionality and serviceability. Remove the back cover of the phone and remove the battery. Now take the wall charger and connect it to your phone without the battery. If any indication appears on the screen or the smartphone screen lights up, then the problem lies precisely in the battery failure.
Service maintenance
Video - If your smartphone screen does not work:
If the phone screen does not turn on, then the problem probably lies in the hardware of the device, and this problem can be solved in the service center. Engineers will check all the components of the device with special instruments, and then announce the breakdown itself and its cause, as well as the time and cost of repairs. In addition, there are several other obvious signs that the phone itself is faulty:
- severe overheating when not in operation and even in operation,
- lack of response to connecting to a computer,
- no response to connection to the power supply.
These and other signs indicate the need to contact a service center, because repairing the device yourself will not only void your warranty on it, but may also result in the phone being damaged or receiving an electric shock.
Remember that safety comes first, and if the screen on your phone does not turn on, then it can and should be diagnosed and repaired.
A mobile phone is a unique device that is very difficult for a modern person to do without. It is he who helps to solve difficult work issues, arrange a meeting with business partners, listen to the favorite voice of relatives and loved ones, handle in case of an accident, etc.
It's nice to know that you have this useful and always available “friend” in your pocket. But what a disappointment if at some point you notice that your Android phone does not turn on? What to do in such a situation? And what to do if, on the contrary, it does not turn off?
Changing the sleep time on Windows 7
If you do not use a computer or laptop for a while, the display turns off and you get the feeling that the machine is turned off. This situation indicates two situations: either the screen turned off, or the PC went into sleep mode. The specified frames are not always satisfactory, and it is often necessary to change the sleep time on Windows 7.
A small digression. All modes are divided into 3 categories:
- Sleep mode (sleep) is a state of the PC in which there is no shutdown, but reduced power is supplied. All open objects continue to be stored in RAM, allowing you to continue working instantly.
- Hibernation – designed more for laptops. The entire contents of the RAM are flushed to the hard drive, then the power is turned off. Resumption of operation takes much longer, but battery savings increase. This is what distinguishes hibernation from sleep.
- Hybrid mode – combines the characteristics of sleep and hibernation.
Methods to open the power option
To change the sleep mode transition time in Windows 7, there is an option called “power”, which can be found in 4 ways:
1. Click “start”, enter “power supply” in the search and select the item shown in the picture.
2. Hold down the Win + R keys and copy powercfg.cpl into the “Run” command input window. Click OK or Enter.
3. The longest path. Go to the start menu, select control panel. Make sure that there are large or small icons in the “view” field. In the list of Windows 7 options, find the “power options” option.
4. On a laptop, when you click on the button with the triangle icon in the tray, hidden icons will appear. Among them, find the icon in the shape of a battery and a power plug, click on it with the left button. In the pop-up window, click on any of the 2 links at the bottom.
After selecting one of the methods, a window for setting power consumption and sleep mode in Windows 7 with adjustable configurations will open. In the window, click the link to go to sleep mode, it is located on the left.
Here you will be prompted to change the settings of the installed power plan. In my case, this is the “energy saving” plan. It will always be possible to reset the settings to default, so don't be afraid to experiment.
On the laptop you will see 2 columns:
Each column is given individual parameters. On a regular PC, accordingly, there will be 1 column.
To reduce or increase the time it takes to enter sleep mode and turn off the display, click on the button located opposite the corresponding option. Set your time frame and click “save changes”.
If you always don't leave your PC idle for long periods of time, then select "never". This will disable sleep mode on your Windows 7.
To set your own transition time, click the change advanced settings link.
In the window We are interested in 2 sections:
Click on “sleep”, then “sleep after” and set your own time, down to the minute.
Click on “screen”, then on “turn off screen after” and also set the time period.
You can set other parameters, but after making changes, be sure to click the “apply” button and OK.
With these manipulations you can change the time it takes to go into sleep mode in Windows 7. Basically, sleep has practical benefits on laptops or other devices that use a battery. On a desktop computer, this option is practically useless.

Don't rush to conclusions
So, if your smartphone or mobile phone with the Android operating system installed suddenly stops turning on or off, there is no need to panic right away. Firstly, if you behave calmly, it will relieve your nerves from overstrain, and secondly, it will protect you from unreasonable actions.
In particular, if you are not a phone repair specialist, do not rush to immediately disassemble your smartphone piece by piece and see what’s broken. This approach will not save, but on the contrary, will bring a lot of new problems.
We look for the reason and reason
If your phone turns on and off, then there are no questions about its operation. If, on the contrary, it does not turn on, it is worth finding out the reason. So, let’s assume that recently your smartphone was working properly and suddenly stopped. What can be wrong?
Carefully inspect the smartphone and make another attempt to turn it on. If this does not happen, try connecting it to a charger. It is quite possible that the cause of this is a battery that has died prematurely. And if this is the case, then after some time your mobile phone will turn on without any problems and work in full mode.
When doing this, pay attention to your battery charge. If you just charged your smartphone a day ago, and it has already died, then audit all the options involved in the phone that work in continuous mode. As we have already determined, quite often the Android phone does not turn on due to a low battery charge.
It should be noted that the battery may run low due to Wi-Fi, Bluetooth, and Viber being turned on around the clock, which are famous for their ability to quickly consume your current battery charge. If this is the case, use alternative software that allows you to save battery power, or enable the above options only as you use them. You shouldn't keep them on all day.
How to disable screen fading on Windows 7
For laptop computers, long-term battery life is very important. It is the image that consumes most of the energy. Therefore, turning off the display is one of the most requested functions. It can be done in several ways.
1 You can reduce the screen brightness to the minimum level. There is a key combination for this. Pay attention to the “Fn” button, which is located in the lower left corner of the keyboard.
The second button depends on the model of computer you are using. It will definitely be placed among the row of buttons – “F1” – “F12”, which are located at the top of the keyboard.
Open the instructions for your computer and find the required key or use the “poke method”. After pressing this key, the screen will turn on again.
2 You can also just wait for the monitor to go out on its own.
To avoid waiting too long, set the parameters to a convenient time after which the monitor should turn off.
Remember that it will only turn off if you do not perform any actions on the computer for a set amount of time.
3 For example, in Windows 7 you need to click on the button with the image of a battery, which is located on the bottom taskbar. Then select the “Settings options” option, in the window that opens – “Setting screen off”. Set the appropriate options and save the changes.
4 For impatient and lazy people, there is another remedy - slam the computer lid. After closing the lid, the screen will immediately stop illuminating everything around and after a certain time will go out on its own if you first set the appropriate settings.
5 In “Settings”, select the “Power and Lid” option, then “Close the Lid”. For the “On Battery” and “On Mains” options, select the “Not Required” setting.
Save your changes. Now, when you close the computer lid, the monitor will turn off automatically.
The method will not affect the operation of the computer in any way and will not harm the system.
6 For Mac OS, there is another key combination to quickly turn off the monitor - “Ctrl” + “Shift” + “Eject”. You can also put this function in one of the corners of the screen. If necessary, simply hover over a function and the screen will go dark automatically.
7 If you plan to use an additional screen for your computer, the built-in one must be turned off. Click on the “Device Manager” option, then on “Monitors”.
Right-click on the screen name and select the “Turn off” option. If this happens, you won't be able to use your computer's display until you turn it on again.
This technique is not recommended to be used too often.
8 Many people set the display to turn off automatically. But if you read information or watch videos, you will have to constantly take action so that the system does not turn off the screen.
To avoid such a situation, special programs have been developed. They allow you to turn off the display if necessary. One of these utilities is Dark – Turn Off Monitor.
After installing it, a shortcut will appear on your desktop, double-clicking on it will turn off the monitor. Pressing any button will turn it on again.
Experts recommend carefully studying the instructions for your computer. Having found out the purpose of the function keys, you can immediately set everything correctly and not do anything unnecessary.

How to Set Windows 10 Screen Timeout
In the Windows 10 operating system, the wait period before turning off the monitor to save power is usually 10 minutes. In addition, when the monitor turns off, the computer locks.
Further work is possible only after entering the password for the user login used.
And if on PCs used as workstations in large companies and in production this is a necessary measure due to security requirements, then on ordinary home computers there is no need for this.

To configure the Windows screen timeout, simply click on the down arrow and a drop-down list will appear with all possible values. You can set it to half an hour, an hour, or even disable this function to remove the display from turning off completely.
The wires or contacts in the phone have come loose
We connected the charger - the Android phone does not turn on. What to do in this case? Carefully inspect your smartphone again. Carefully examine all wiring and connections. It is quite possible that your charger has a bad contact, or one of the wires has come loose. The existing connectors can be checked using a special screwdriver with an indicator, which is applied to the joint.
Also, as an alternative, you can replace the charger and check whether the phone will charge or not.
Setting up sleep mode using native Android tools
You can configure the time after which Android turns off the screen and goes into sleep mode due to user inactivity in the system settings. To do this, you need to go to the settings of your smartphone or tablet, although it should sound more correctly like “go to Android settings” and select the “Screen” section, where in the “Sleep mode” subsection set the required time or turn off this option altogether, if it is possible to turn it off device manufacturer.
The screenshots show the timeout settings of the Huawei MediaPad T3 8 tablet, which does not have the ability to disable sleep mode. In other gadgets, this may be the “Never” or “Disable sleep mode” item.
This is the simplest way, but far from the most rational, because... in this case, the waiting time is set for all installed applications. If we need to set a different wait time for each program or completely disable the transition to sleep mode while a specific application is running, then we will have to use special utilities.
The phone does not turn off or does not turn on due to the start button
The cause of your smartphone not working may be a malfunction in the on/off button. It may come off, it loses contact, etc. The keyboard may also stick, for example, if it gets wet, or become blocked as a result of the phone being dropped. If any of these variations exist in your smartphone, you must immediately contact a specialist service center. In this case, only experts will be able to determine the cause of the breakdown.
To restore the operation of your device, the following actions are suitable:
- replacement ;
- restoration of assembly soldering;
- replacing the keyboard controller;
- Carrying out complete cleaning and purging of the device.
It's all the fault of the memory card
If your Fly phone does not turn on, it may be due to a faulty or defective memory card. This happens if it was purchased from a dubious store or was released by an incomprehensible and unknown organization. As a result of this, your phone, as people say, “freezes and glitches.” To avoid this, try to purchase the card at the same place where you bought the phone. Or give preference to popular manufacturing companies.
In addition, there may be too much information recorded on your memory card. For the same reason, there may be malfunctions in the operation of the smartphone. To avoid this, perform formatting on time.
The reason is a virus program
If your Samsung Galaxy phone does not turn on, the reason may be a virus that has penetrated the Android system. You can “pick up” it while downloading a gaming application, watching videos or pictures. In a word, install an antivirus on your smartphone and update it regularly. And also try to avoid going to dubious sites and forums. In the end, if no actions with the phone bring positive results, you can always reflash the phone and it will work like new.
Power settings in Windows 7
So, you have the Windows 7 operating system and your monitor screen quickly goes blank, be it a laptop or a desktop computer?!
Go to the Power
.
To do this, simply taskbar
(as shown in the picture below) and select
Power Options
:
If you do not see the power icon on the taskbar, then click on the small triangle icon (to the left of the power icon in the picture) with the left mouse button and find the power icon.
You can also access Power Options in another way.
Start Menu
->
Control Panel
:
And Power Supply
:
So, whether we entered the Power Options section through the Taskbar or through the Start menu, now in the selected power plan we click on the link with its settings:
And here we can configure it the way we need:
1. After how long to dim the display (monitor) or turn it off so that it goes out completely, as well as when to put the computer into sleep mode and adjust the screen brightness.
Moreover, this can also be configured separately for a laptop: From battery
or
From the network
.
And, of course, after changing the settings, you need to save them for them to take effect:
So, if your monitor (laptop) screen goes dark quite quickly, try increasing the time here in the corresponding parameters (when to dim and turn off the display).
2. Since we’ve gotten into these settings, perhaps someone will be interested in delving into the additional settings:
But this no longer concerns the topic raised, so I’ll leave it to you to learn on your own, especially since everything there is quite intuitive.
Smartphone screen does not turn off
Sometimes, after turning off, your smartphone screen may not turn off. On the contrary, standard phone screensavers in the “Hello Moto” style may appear on it (may differ depending on the manufacturer). In this case, the screen does not go dark, and the phone does not turn off, and also does not respond to other commands. What to do? In this situation, the easiest option is to open the back cover of the phone, pull it out and put it back in. As a result, the phone will turn off and then turn on, resetting the initial “frozen” settings.
If even after such simple manipulations the Lenovo phone does not turn on, try doing the same thing by additionally removing and inserting your SIM card back.
Why does the mobile phone screen go blank?
One of the default features of smartphones is “sleep mode,” which is activated if the device is not used by the user for a while, usually 30 seconds. Ordinary push-button mobile phones were endowed with the same property long before the advent of smart phones, so automatically turning off the display is not news to anyone. The option allows you to significantly save the device’s battery power, since the active screen consumes a lot of energy. In addition, modern smartphones have the option of locking the display and touch buttons when making calls, which prevents accidental clicks during calls and also prevents third parties from gaining access to the device.
Although turning off the screen automatically is useful, in some situations where the user is not physically interacting with the phone, this feature becomes a problem, preventing certain tasks from being completed. In this case, you can increase the time the display is active or make sure that it does not go out at all. Let's look at how to do this below.
We remember the events of the past days
When your Android phone won't turn on - what to do? Sometimes you can find the answer to this question only by remembering the events of past days. To do this, recreate in your memory all your actions that you have performed recently. For example, you could accidentally drop your smartphone, sit on it, or push it off the dresser while cleaning.
If the cause of your mobile device malfunction is a fall from a height, even a small one, you should immediately contact a repairman.
Phone won't turn on after flashing
If you sent your phone for firmware, but after it your device still does not turn on, contact the organization that performed this procedure. In extreme cases, they will discover the error and redo their work.
The reason here may lie in an error. In addition, it is recommended to contact the service center and report that the phone does not turn on after flashing the firmware. Then order a full computer diagnostic. Thanks to this service, you will understand the cause of the malfunction and next time you will be able to prevent it in time.
The reason is weather phenomena
Let's consider one more case. Suppose you put your smartphone on charge and went to bed, there was a thunderstorm at night, and in the morning you discovered that your Android phone does not turn on. What to do? First, carry out the above procedure on the battery. Secondly, alternately press the power key and volume key.
If there is no effect on your actions, you should take the phone in for repair. It is quite possible that he was struck by lightning. To avoid this problem, try not to charge your mobile phone at night. You should not do this during a thunderstorm either.
