Why the tablet turned off and does not turn on

For the majority of individuals, the tablet has transformed into more than just a high-end electronic device, it has become an essential tool. It houses a plethora of essential information such as contacts, crucial files, and linked social media accounts. Consequently, when the tablet suddenly powers off, a momentary wave of anxiety sweeps over. The immediate concern is to swiftly diagnose the underlying issue.

The main causes

No matter the make or price of the device, there are three potential issues that may arise:

• Physical damage, which can impact the power button, connector, and charging cable.
• Electrical damage, typically occurring in the battery.
• Software damage caused by viruses.

Power button breakage

The ON button becomes damaged after experiencing a fall (even a drop from a height of just 1 meter). The issues are typically indicated by a misaligned or loose button. To fix this problem, it is necessary to disassemble the device and assess the condition of the internal mechanisms.

It is worth noting that replacing the button can be handled by users themselves, whereas dealing with the membrane may require either increased effort or assistance from a professional repair service.

Disassembling oneself and inspecting the power button

Problems with the power connector

The occurrence happens when there is careless handling of the component: abrupt disconnection from the tablet, moisture infiltration. Consequently, the pin connector gets damaged. The only way to fix it is by dismantling the device into its individual parts and entirely replacing the charging socket.

Screen malfunctions

If the tablet turns on but does not fully start and the screen blinks, there may be an issue with the screen. Even if there are no visible scratches on the monitor after a fall, it is possible that the screen itself has been damaged. To confirm if the problem is indeed with the monitor, it is recommended to connect the device to a power source. Once the battery has been sufficiently charged, try pressing the Power button and wait for 15 minutes. During this time, a functioning screen should heat up on the right side of the device. If there is still no display on the monitor, you can remove the cover and inspect the contacts yourself.

This issue arises if you connect the charger without a network stabilizer or frequently spill water on it. Regardless, you will need to purchase a new one. The problem becomes more challenging for owners of Chinese devices, as they don’t always have access to original chargers. To find a suitable replacement, you will need to consider the technical specifications of the faulty charger, such as voltage and amperage.

If everything seems to be in order, but the screen still remains dark, it is possible that the battery has simply malfunctioned. The majority of built-in batteries are designed to have a limited number of charge cycles. To determine if the charger is indeed fully functional, you can check the voltage. The measured value should align with the specified values in the table. If it does not match – it becomes evident why a functional tablet fails to power on. In this case, you can proceed to purchase a replacement battery.

Battery voltage – 3.7 V

Battery voltage – 7.4 V

Battery voltage – 7.4 V

Water getting inside the case

Any liquid that enters the device can be detrimental to its functionality. Numerous individuals, who lack experience and knowledge, make the mistake of attempting to dry a wet device using a hair dryer or simply turning it back on. Such actions should be avoided at all costs, as they greatly increase the risk of permanently damaging the tablet. Thus, in the event of water damage, it is essential to promptly power off the tablet and remove the battery from its enclosure. Afterward, both components should be taken to a professional service center for repair.

Software malfunction

If you are experiencing the issue where the tablet powers on but quickly shuts off, and there have been no instances of the device falling or coming into contact with liquids, it is possible that there is a software problem. To test this theory, follow these steps:

1. Press and hold the power button for approximately 30 seconds.
2. Release the power button.
3. Press the power button again, but this time hold it for 5 seconds.

If the tablet still does not turn on, you may need to perform a forced reboot. Typically, Android tablets have a small hole on the body that is distinguishable from a speaker or microphone. Inside this hole, there is a hidden button that can reboot the entire system. To press it, you can use a paper clip or the key that came with your device.

Important! If restarting doesn’t solve the problem, you may consider taking drastic measures – performing a complete data reset: everything will be erased, except for the files that were saved to any cloud storage.

To do a Hard Reset, follow these steps:

• While the system is booting up, press the designated keys (usually the power button and the volume key) to enter Recovery mode;
• In the menu that appears, choose Settings, then select Format System, and finally Recovery Android.

Click the buttons to access Recovery mode

For iPad users, the process is slightly different. To test the functionality of your device, you will need to connect it to a computer using a proprietary cable. Once connected, open the iTunes program on your computer. Then, simultaneously press the Home and Power buttons on your tablet. If your device is working properly, the Apple logo and menu will appear. From the menu, select "Update system."

If a simple restart does not resolve the issue, the only option left is to flash the system and reset all settings. However, it is not recommended to perform this task yourself. First, it will void the warranty. Second, there is a high risk of making a mistake and rendering the tablet useless.

Virus or lack of memory

In either scenario, the device fails to power on prior to the splash screen. To address this issue, it becomes necessary to establish a connection between the tablet and a functional laptop using a USB cable. In the event of a virus infection, a thorough system cleaning with an antivirus program is recommended. If the device is experiencing a storage shortage, it will be necessary to manually delete any superfluous applications. In both circumstances, it is crucial to exercise caution and ensure that essential software is not inadvertently deleted.

An antivirus should be used to scan all files.
