How to restart a Huawei Mediapad tablet if it freezes and won’t turn on

Tablet computers have confidently entered our lives and accompany us both on vacation and at work. It is a very unpleasant situation when the device does not turn on at the most crucial moment or does not load beyond the Android logo. The most basic thing is that it’s simply discharged, especially if you actively used the device during the day or night. Then all you need to revive it is to connect the tablet to the charger and wait a few minutes before starting it up.

But there are also more global problems and they can be divided into three groups:

mechanical
electronic
software.

This kind of trouble can happen not only with cheap Android brands (Digma, Chuwi, Teclast, Cube, FNF, PiPO, Onda, Colorfly, Ainol, Ramos, Vido, No-name), but also with market leaders - Apple, Asus, Acer , Sony, Lenovo, Samsung, Huawei.

Let's take a closer look at all three factors to determine exactly why the tablet won't turn on. The instructions are universal and are suitable for both Android, Windows, and iPad, but each case has its own characteristics.

Mechanical problems

Power button is stuck or broken

If the tablet computer fell, the power key could be the first to be damaged. Inspect it; it should not sink or wobble; when pressed, there should be a characteristic clicking sound. If there are any irregularities in the operation of the key, you will have to disassemble the tablet and inspect the nature of the damage. Most likely you will need to solder the key or replace it with a new one if the contacts are broken. Repairing a mechanical button will not be a problem; you will have to tinker with the membrane one.

The charging connector has broken off

If the ON/OFF key is working properly, then you should inspect the memory connector. If you sin by pulling the wire out of the socket very sharply, exposing your mobile computer to moisture, or frequently dropping it, then sooner or later this will lead to damage to the contact connector. Deformation of the socket leads to the fact that the plug will not fit into the connector, will not fit completely, and may even be blocked by some part of the housing or break off if the impact was quite strong. Damage to the pin connector will result in the device not charging. And in this case, you will have to disassemble the case and solder the contacts or completely change the charge socket.

Broken wire

It is possible that the device does not start simply because you have a faulty memory. Check the case for swelling, distortions, and whether the cable is broken. If there is damage in the wire, then it is quite possible to replace it yourself. Fractures in the cord are not visible, so it would be correct to check its functionality by connecting it to a phone, e-reader, etc. and check the charge supply.

The removable battery can be charged directly. This method is not safe for the battery, but if you are willing to take the risk, it is possible. The battery becomes unusable very quickly from this process, so you should not abuse this charging method.

There is a safer way to recharge the battery - using a universal charger called a “frog”

Use these methods only if you are completely confident in your abilities. It is better to entrust repairs to professionals rather than take risks.

Electronic problems

The charger burned out

If the charger was exposed to moisture or was connected to the network without a voltage stabilizer, then it could easily burn out. The only way out is to purchase a new and preferably original one, which is not always possible.

For brands such as Asus fonepad 7 me372cg, Huawei MediaPad M2, Samsung SM-T311 Galaxy Tab 3 8.0, Sony Xperia Z2 Tablet, LENOVO Tab a5500 it is possible to buy an original charger, then for Chinese brands smarto 3gdi10, 4good light at300, digma plane 7546s 3g, explay xl2 3g, ainol novo 9 spark, bq, thomson hero10sco, irbis tz185 you will have to select a memory based on the characteristics of the burnt block. Pay attention to the voltage (standard - 5 volts) and how many amperes (recommended from 1A to 2.5A) the purchased adapter produces

In the meantime, try charging from USB by connecting it to a computer or external battery.

This topic is discussed in more detail in this article.

Battery died

Modern gadgets are equipped with lithium-ion or lithium polymer batteries. Such batteries are equipped with charge controllers, which are responsible for preventing the battery from being deeply discharged. Such batteries cannot be stored - batteries tend to lose capacity. It is necessary to ensure that they do not discharge to zero and do not overheat above 45 degrees.

The average battery life with active use is 3–4 years (about 300-400 cycles).

To check the battery, you need to measure the voltage on the battery and the board. Remove the battery and connect the charger. Now check the readings on the voltmeter, the parameters should correspond to the following data:

CHARGER	BATTERY	PAY
5 V	3.7V	3.9 – 4.2 V
9V	7.4V	7.9 – 8.2 V
12 V	7.4V	7.9 – 12.2 V

Water got on the microcircuits

Contact with water is very harmful. Anything can happen here - oxidation of contacts, malfunction of speakers, fire, overheating. When liquid gets on the microcircuits, it causes a short circuit and turns smart equipment into a brick. If it suddenly happens that water does get in, then the first thing to do is turn it off. Then turn the tablet over with the display facing up to prevent liquid from penetrating the internal elements. If possible, remove the battery, SIM card and flash drive. Remove moisture thoroughly. You can place the tablet in the same position in absorbent absorbents - the simplest and most widely available is rice. Afterwards, let the device dry completely for at least a day.

Fault in the screen or video adapter

It happens that the Tablet PC is functioning and the display simply does not light up. Touch the back cover - it should warm up. A running tablet makes a slight noise or vibration when turned on. There are two options - either after the firmware, viruses or other software influence, the display does not start, the touchscreen is damaged or the video adapter has died. In the first case, a factory reset or flashing is required. You will need to replace the cable if the latter comes off after an impact.

To check the video adapter you will need a TV or computer. New generation gadgets have a mini or micro HDMI video output, with which you can connect your tablet to your TV. If the problem is in the display, the image will appear, but if the video adapter is damaged, the TV screen will remain dark. It is better to entrust such repairs to specialists.

Burnt out processor or memory

Under heavy daily load and running a large number of applications, the processor may overheat or even burn out, which will cause a malfunction of the mobile computer. Very few modern devices use a built-in cooling system. Moreover, you shouldn’t count on it if you have a cheap mobile PC. The more you use your tablet, the more often your CPU overheats, which leads to loss of performance. If the maximum permissible temperatures are exceeded, microcircuits, cables, RAM, and printed circuit boards suffer, which will lead to short circuits of the power circuits. Processor repair is carried out only at a service center, but it will cost a pretty penny.

If the tablet does not turn on, you should check the flash memory. If you have experience, you can try to make repairs yourself, even increasing it.

None of the above helps - perhaps the problem is in the software.

Software failure

Sleep mode activated

Sleep mode is one of the common reasons why a gadget does not start. If, when the operating system goes into sleep state, the device freezes and cannot subsequently start loading Android. To remove sleep mode, connect the tablet to the charger and turn it on after a few minutes. To avoid such difficulties in the future, disable sleep mode in the settings.

Viruses

It is rare that a device does not function due to a virus attack. More often it loads at least to the splash screen and freezes. In this situation, it is necessary to carry out a complete cleaning with a good antivirus program. To do this, connect the tablet to your personal computer or laptop using a USB cable. After this, reset the settings to factory defaults (the so-called Hard Reset, details here).

Lack of memory

Sometimes the tablet computer does not turn on due to lack of memory. Remove the card and try to turn on the device without it. Clean the OS from recently installed applications, remove unnecessary ones. Programs that are incompatible or incorrectly installed overload the RAM. Also avoid forcefully shutting down the system so as not to delete files responsible for its operation.

After removing third-party software

If the gadget stops functioning after deleting the application, then returning to factory settings will help:

remove the flash card and sim card
Press the Volume and Power buttons at the same time
navigate through the BIOS items using the volume buttons, select the Power key
select the item – Wipe data/factory reset

Be prepared for the loss of personal data.

Before installing any software, you must ensure that it is compatible with your device. For example, a program such as Paint Tool SAI, which works great on powerful devices. But after launching which a simple tablet (dns, dexp, supra, digma, equator, techet, explay, Thomson, nexus, prestige, etc.) freezes and stops responding to any actions, because it is not designed to install this software according to its characteristics . After uninstalling this application, graphics drivers crash and disrupt the operation of the PC. Only graphics tablets such as Wacom Intuos are suitable for such a program. Don’t load anything that is not intended for the device and then you won’t have to ask the eternal “why.”

After flashing

The flashing process requires a certain skill, so unsuccessful intervention often leads to the loss of functionality of the mobile PC. Most likely, the firmware version is incompatible with the Android OS installed on the gadget. In addition, if the cord is disconnected during the process, this is a guarantee of “bricking”. We recommend rolling back the software to its original state or using low-level utilities to restore functionality.

If a disconnect occurs during the firmware installation and data transfer is interrupted, you must perform the installation again.

It may also be the fault of the update developer - they turned out to be incompatible with this version of Android. Return everything to its original form and disable the update in the settings. At least until you verify the reliability and performance of these updates. Download updates that are appropriate for your model - Huawei t1 701u, acer w700, Samsung GT-P5100 galaxy tab 2, Samsung Galaxy Note 10.1 GT-N8000, samsung galaxy tab a 10 5 sm t 595, Samsung sm t311. It is more difficult to find updates and firmware for little-known and cheap brands - 4good light at200, Irbis tz720, LG G Pad 8.0, oysters t12 3g, oysters t72hm 3g, prestigio MultiPad PMP5580C, Ritmix RMD-1050, Roverpad Air Q10 3g, Irbis tz178, wexler tab 7b, 3q tablet pc qoo rc0721b, Chuwi, dexp, Turbokids, Smarto, etc.

If when loading the OS there is a reset or freeze on the Android logo, then all is not lost and you can make the repair yourself. You can restore your tablet PC from a bricked state using the Recovery program by installing it on your PC and connecting the tablet. But each specific model must be dealt with separately; there are no general instructions.

Reboot the tablet if the sensor does not work

You can restart your Huawei tablet via your computer. This is relevant if the gadget is frozen, the sensor refuses to respond, and one of the buttons does not function. To reboot via PC, you need to install a special utility - Reboot.

Connect the tablet to the computer via a cable and right-click on the icon located on the taskbar. Select Reboot.

Do not rush to immediately turn off the tablet, wait until it restarts. If the described instructions did not help to revive the device and it stopped turning on, contact a service center.

But there are also more global problems and they can be divided into three groups:

Such trouble can happen not only with cheap brands on Android (Digma, Chuwi, Teclast, Cube, FNF, PiPO, Onda, Colorfly, Ainol, Ramos, Vido, No-name), but also with market leaders - Apple, Asus, Acer , Sony, Lenovo, Samsung, Huawei.

Question answer

The tablet turns on and turns off immediately (cyclic boot)

This happens after an incorrect flashing or installation of software with access to Root rights. First of all, try resetting to factory settings through the bootloader menu (Recover mode - hold down the ON + Volume UP button). If this option does not help, then reflash the device with the official, stable version of the software.

The screen flashes or streaks

Careless handling of the tablet leads to disruption of the display and other components. The slightest impact or fall may cause the screen to malfunction. The most common is the disconnection of the screen module cable. To restore, you need to open the device and install it in the appropriate slot.

After a fall, the matrix and touchscreen will be damaged. The display will begin to ripple, streak, show “partially”, and will not turn off. This requires the hand of a master. And be prepared for expensive repairs.

A software glitch is the rarest cause of display flickering. A factory reset will help here. As a last resort - flashing with a stable version of the software.

Also, stripes and blinking may appear due to overheating of the gadget or water ingress.

Doesn't load past the logo

If the screen is on (works, but black), and the device freezes and does not boot, it freezes after entering the password. Use the reset button. This is what will help if the operating system stops loading. If you do not find a reset on your Tablet PC, then try clearing the cache:

Press and hold the Power and Volume keys at the same time
Select wipe cache from the menu
Select the inscription reboot system now

If this does not help, then in the same menu we reset the settings.

How to reboot a Huawei tablet if it freezes and won’t turn off

If the freeze is due to a system error, then you should do the following:

Press the Power button for 15-20 seconds. You may not have held the key long enough.
Otherwise, pay attention to the recess located on the tablet body and insert a needle or pin there. This will force the device to reboot.
After downloading, it is recommended to reset the settings to default. The procedure involves completely deleting information on the tablet.
Go to settings and select the Privacy or Backup & Reset tab.
Click on "Reset".
The tablet will reboot again.

Resetting to factory settings requires sufficient battery charge in the device. It is recommended to connect it to the network.

The second method is radical - Hard Reset. The information on your tablet will be deleted in the same way as after resetting the settings. In this case, restoration is impossible, and the parameters will be reset to factory settings. Instructions:

Take out the SIM card and flash card if available.
Press and hold two buttons – Power and Volume Down. Hold them for 15 seconds. After vibration, you can release the buttons.
The system will open the menu, use the volume control to select Setting.
Next, click Format System.
Once the procedure is complete, a reboot will begin.

Recommendations

And finally - if the new device goes out and does not respond to the power button, then perhaps the battery has completely discharged due to long-term non-use of the device. Connect the tablet to the charger and wait. It is necessary to carry out several charge/discharge cycles for the battery to return to normal. If it doesn't help, replace it under warranty.

If the tablet starts but does not function properly, clean it with an antivirus in safe mode and remove third-party applications. Clear your cache. This way you will be able to preserve personal data, but get rid of the slag in the system.

We have analyzed the reasons and now it is clear that most problems with a Tablet PC can be solved by resetting the settings via entering hard recovery.

Method 1: Check the charger and cable

Your Samsung smartphone may be dead and won’t turn on. You connected the charger but nothing happens. First of all, try to take a charger from another gadget and if the phone reacts to it and begins to receive a charge, then that is the problem. Next, you should change the USB cable to determine what exactly has stopped working. If, after replacing the wire, your charger begins to charge the smartphone battery, then the reason is that it is faulty.

conclusions

Taking good care of your favorite device is the key to long-term operation. Timely replenishment of energy, careful loading of third-party software - this will only contribute to the long and fruitful use of the gadget. Don’t forget to clear the RAM, don’t overload the device, and then you won’t have to look for answers to the question “where to go and what to do” if the tablet stops turning on. You can fix it yourself, but if you are not confident in your abilities, it is better to trust the specialists.
