Samsung tablet turns on and off. ASUS tablet turns off

Unfortunately for many tablet owners, a situation often arises when the beloved device does not want to turn on - it spontaneously turns off after a short attempt to boot. In this case, you can try to correct this situation on our own, since the only alternative to this is going to the store and returning the tablet for repair under warranty. So, what can you do with your own hands?

Resetting the tablet to factory settings (hard reset)

Most often, the time between loading the tablet and its random shutdown is limited and a person is not able to perform additional manipulations with it during these moments. Therefore, to get into the factory menu, you must first charge the tablet. After this, when you turn it on, you need to hold down a certain key combination (usually the volume up or down button together with the power button, or all at once). Please keep in mind that the specific steps may vary slightly depending on the different devices depending on the model and manufacturer.

In any case, the operation called Hard Reset, runs from the factory menu, where you need to find special item menu Selecting functions is done with the power button, and moving through items is done with the volume buttons. After the device executes the command, you need to select " Reboot system now", which will trigger a reboot. User settings and data on the built-in flash drive will be lost, but there is a very high chance of getting a normally working tablet.
If this does not help, you can proceed to the next step

Flashing the tablet

Such actions must be performed extremely carefully and only if other methods have not had the desired effect. Flashing also helps in cases where it is simply impossible to get into the factory menu due to the features of the device.
Firmware for specific model It’s best to search on specialized forums, like 4pda, or on the official websites of the manufacturer. On the forums, in addition to the firmware itself, you can find step by step guide on its installation. Please take into account that no one else will search for the firmware except you, but if the tablet came out quite a long time ago, then there is a high probability that other people have flashed the device before. And, as they say, God himself commanded that such information be shared on the Internet.

Why the tablet turns off by itself, other symbols can be drawn precisely by the palette of those supported, linked between why the tablet turns off by itself, so they are better perceived against the background of a geographic map. It's not much, but for long work This screen is quite enough.

The tablet is constantly lying on the table and from time to time it turns on itself, and a little later it turns off. Video review and unboxing of Samsung Galaxy Tab 2 7.0 P3100 Screen and cameras B this tablet used PLS matrix, with a resolution of 1024 x 600 pixels.

Well, since we are talking about hardware power, it is worth noting that the amount of RAM here is 1 GB, which has already become a kind of standard for devices running Android control 4.0. Usually this can be easily treated with a small patch that you need to download and install on your tablet. The front one has a VGA resolution and very good quality of the transmitted image, but the rear one is capable of taking pictures with dimensions of 2048 x 1536 pixels, which is 3.2 MP.

There is no need to disassemble the tablet to remove the battery. Because in tablets it is connected by a soldered connection, and a malfunction with the iron cannot occur through it. And other iron problems are difficult to figure out and eliminate, especially for a person without special education.

Why does Android turn off? This problem may be caused by hardware problems or glitches. software. Problems with hardware most often occur at contact points - this is the battery, SIM card, keys, detachable connection between the screen and the circuit board.

To try to cure yourself from a glitch in which the android turns off by itself, you need to open back cover phone and remove the battery. Next, you need to clean all the battery terminals and each connector contact on the phone.

It should be done as a last resort - if resetting the settings did not help, or there is no way to do it (in some Chinese tablets you cannot get into the menu Recovery mode). As I said earlier, on my tablet I can do hard reset The settings are not working, so if something happens, only flashing the firmware helps.

Let's consider the option when the tablet turns on and off. Actually, you have a small choice, only 3 options. The first is to run to the store and return it under warranty. But this is the lot of the weak, and we will try to fix everything ourselves.

I have a tablet 3 7.0 50% or 30% percent of the battery, it turns off on its own, I put the battery there for charging, it turns on normally, it turns on, it works normally, I take it off charging after 15 20 minutes, it turns off again, sometimes it lasts an hour and a half, two hours, what should I do, please help ((

Probably, I will now highlight problems that can be attributed to unstable work wireless network.If this is the case, then most likely your router simply cannot withstand the load and begins to fail. Yes, it will be easier for us to navigate the problem itself and possible solution. The shape of the device is not particularly original, and whatever one may say, it is somewhat reminiscent of tablets from Chinese manufacturers. Although it is understandable, I don’t particularly want to invent anything. The case has a thickness of 11 mm, with dimensions of 194 x 122 mm.

This is the first thing to do. And you need to look for the problem there. Just turn it off from the router and turn it back on. Also, reboot the device that you are trying to connect to the network, or that is experiencing some problems. You need to understand what the problem is.

To do this, it is enough to provoke an increased load on the processor by turning on a “heavy” application, or measure the processor temperature using special utilities. Software failures If the tablet has not fallen, and you are sure that the battery and processor of the device are working properly, then look for the cause of the problem in software failures When various applications or the tablet's operating system is not working correctly, this may cause the device to shut down. IN in this case In first place in popularity we can safely put failures caused by malware, in other words, viruses.

Things tend to break. Mobile phones in this regard is no exception. Sometimes the phone begins to show independence - it turns off and does not turn on. The main reasons for this behavior of the phone are as follows:

Rough handling, falls and impacts lead to mechanical damage to the board and other elements of the phone. This can also be checked. It is enough to bend the phone with your hands. If after such a procedure, the phone freezes or turns off, it means that the reason has been found; it is better to contact the service center for a solution.

It is possible that the power amplifier in the device is damaged, which often happens after a fall. This malfunction leads to an increase in the amount of energy consumed, which results in the phone constantly turning off.

In this category, a common reason why a tablet turns off is bad job device batteries. The fact is that if the assembly is of insufficient quality or there are manufacturing defects, the battery may not fit tightly, as a result of which the circuit opens and the device turns off due to lack of energy.

This problem is resolved using complete cleaning old firmware and installing a new operating system. The same applies to cases when the tablet turns off when 3G is turned on, this can happen either due to malfunction module, or through software errors.

There can be many reasons for overheating, ranging from external factors ( sun rays, heating devices, etc.) and ending with internal ones, for example, excessive load on the processor. In such cases, it is recommended to simply wait until the device cools down. It is also recommended to regularly clean your tablet from dust.

Battery problems can also arise from dropping the tablet. This type devices generally do not withstand falls even from a small height, since their “filling” is quite fragile, it is never possible to say with certainty which part caused the malfunction.

When the Samsung Galaxy S3 i9300 S III is turned off, you will not be able to operate it. This is a serious problem that needs to be resolved as soon as possible. This work can be delegated to our specialists service center pcmol, who always know what to do and how to help. First of all, let's determine the cause of the malfunction.

Based on information posted by users, after a specified period of time, the Samsung Galaxy S III spontaneously turns off and stops responding to the owner’s actions. As reasons for refusal further work smartphone is considered to fail motherboard or NAND memory module.

There is currently an active discussion on the XDA Developers resource about the reasons why samsung smartphone Galaxy S III after 150-200 days of operation stops working and actually turns into a “brick”. At the time of writing the news, the topic has 91 pages and contains 903 messages.

Samsung regularly replaces devices under warranty. Since the number of deaths with original firmware and custom ones is almost the same, it is assumed that the problem is the hardware component and the owners of the replaced ones...

We regularly use Wi-Fi connection, at work and on vacation; this technology wireless communication has become such a part of our everyday life that it is difficult to imagine life without it. A common error is when Wi-Fi suddenly turns off on Android devices, can disrupt the execution of urgent tasks, which means this problem must be solved or prevented.

Sometimes Android loses the network due to a banal freeze on the router: this can be easily checked by connecting to the router with another device. Try restarting the router. If this does not help, then the problem lies in its firmware. In this case, download from the official website updated version Software for your access point and install it.

The most common error when Wi-Fi turns off on Android is associated with the use of mobile phones. antivirus programs. The fact is that the Firewall of such applications simply blocks the network in order to increase security.

Sometimes the problem with connecting to a wireless network occurs due to a software glitch. Mostly Android loses Wi-Fi connection after a software update, but quite often and simply empty space" In this case, the first thing you should try is a general data reset.

The SIM card slot in the GT-P5200 device is located on the top end side. If you are using a GT-P5210 tablet, then, unfortunately, using a SIM card is not possible due to the lack of a SIM slot.

If a smartphone, tablet or phone turns off spontaneously, two circumstances are to blame. This is usually either a software failure caused by system tampering, or physical malfunction device parts.
To solve the problem with a mobile device turning itself off, you need to find out its essence. If you suspect that the hardware is faulty, you need to pay attention to the SIM card, battery, buttons, terminals with connectors. The microprocessor could also fail if your Android smartphone or tablet often overheats during operation.

There is a second reason that leads to the gadget turning off on its own - a malfunction of the operating system. It could have happened for a number of reasons. This includes incorrectly obtaining root rights, incorrect firmware, the presence of viruses, and changes system files, and so on.

The first way is to fix hardware problems.

This is especially true for those users who handle the gadget carelessly: dropping it, shaking it, picking it up with wet hands, using it in the rain, hitting buttons, etc. To eliminate this problem, remove the back cover of the device and remove the battery. All its terminals must be cleaned, and also check the clamping contacts of the smartphone connector.

They also need to be cleaned. But use a small screwdriver for this and never sandpaper. If you rub the connectors, they will oxidize further later. They will also not adhere well to the surface because grooves will appear.

So, how to properly clean contacts. Take a small screwdriver, wrap a piece of cotton wool around it, soak it in a special liquid for contacts and wipe them. If you don't have cleaner (you can find it at your local auto parts store), use alcohol. When you clean the contacts, straighten them a little. This will help them connect better to the battery terminals.

The previous steps apply to smartphones and phones. If you have a tablet, do not disassemble it to remove the battery. In these devices, the battery is connected using a solder connection, and therefore this type of failure can be eliminated. There may be another problem with the tablet hardware, but unless you have special knowledge, you are unlikely to understand what is wrong. In this case, it is better to check the second method, and if it does not work, then take the device for repair.

The second way is to remove all software errors.

Disable your mobile device and open a special Recovery mode, used for disaster recovery systems.

Depending on the devices, you can enter Recovery like this::

1. If you have a tablet, use the following combination: Power key + Volume – (or Volume +).
2. If you have a smartphone/phone, use the previous combination or this: power key + camera (or exit to the main menu) + Volume - (or Volume +).

If after turning on the problem is not solved, reset the settings by clicking on " wipe data / factory reset " All user data will be deleted!

If all else fails, take it in for repair.

As with any hardware problems, today there are several categories of reasons that cause problems in the tablet: viruses, hardware, software.

It can be difficult to identify, so to speak, “by eye,” which category the problem belongs to; in this case, one can only assume that the tablet turns off on its own due to certain problems.

Only our specialists can draw a specific conclusion as to why this happens, and they will be able to remove these problems. Next, let's look at the most common reasons that may be responsible for your portable device turning off.

Disconnection due to problems with the tablet

The most common reason in this category why a tablet turns off is poor battery performance in the device itself. If there are manufacturing defects or poor assembly quality when turned on, the battery may not fit tightly to the tablet and in this situation the circuit opens and the tablet itself turns off due to the lack of incoming energy.

Problems with the battery can occur if the tablet computer itself is dropped. This type generally does not tolerate drops of any kind, even from a seemingly small height, since the “insides” of tablets are quite fragile and you can never say with certainty which part caused problems with the tablet.

Regarding the hardware, a common problem is overheating of the tablet itself, but models from companies such as Asus, Explay, Lenovo, Samsung, as a rule, are not susceptible to this problem. Overheating can be caused by: external factors, and internal. In such cases, it is recommended to simply put the gadget aside for a while.

The tablet turns off spontaneously due to viruses

When using your tablet to access the Internet, it is recommended to frequently check it for viruses. In many cases, even with installed antivirus the owner of the tablet can “pick up” a virus, which will subsequently lead to periodic, or even frequent shutdowns portable device.

Device shutdown due to software glitch

Another category of reasons why a tablet turns off is software errors. In this situation, many may remember that they should not install software on their tablet from unverified or dubious sources, as well as programs that may later conflict with each other during installation. But in some cases, tablet owners may not install anything on their tablet, and still they will not be spared the problem of its unauthorized shutdown. Here the problems may lie precisely in the original firmware installed on the gadget even before it was sold.

Some tablet computers“suffer” from incorrect determination of the position of the device itself in space. Even if the owner simply picks it up in a special way or throws it onto a soft surface (sofa) from a height of ten centimeters, it can turn off.

This problem can be resolved by cleaning the old firmware and installing a new operating system. This also applies to cases when tablet computers turn off when 3G is turned on. This may occur due to an incorrect process. indoor module, or due to software errors in the gadget.

In such cases, when software errors, the best solution will reset the settings to factory defaults. If there is no positive effect, it is recommended to completely replace the firmware.

If you have problems with your tablet and you can’t handle them yourself, then we suggest using our service center!

In a situation where any device, not just Android, turns off spontaneously, two reasons may be involved.

Why does Android turn itself off? Hardware problems or software glitches may be involved in this problem. Hardware problems most often occur at contact points - the battery, SIM card, keys, and the detachable connection between the screen and the circuit board.

Also, hardware-related breakdowns occur due to overheating, specifically the video processor, most often the microprocessor. Software failures are a consequence of turning off the Android smartphone, or after flashing the Android OS, or if a malicious program was installed.

To independently fix a glitch in which your Android smartphone turns off by itself, you can try two methods.

The first way is to fix hardware problems.

After using a phone or tablet for a long time, contact points are broken. At the terminals battery and the connectors of the device, oxidation occurs, or solder connections on the contact pads of the circuit board are destroyed.

This especially often happens after careless handling of the device: when it was thrown into water, doused with water, picked up with wet hands, dropped on the floor, pressed in a pocket, or tapped on the keys.

To try to cure yourself from a glitch in which the Android turns off by itself, you need to open the back cover of the phone and remove the battery. Next you need to clean all the battery terminals and each connector contact on the phone.

Do not rub them with sandpaper, after which they oxidize even more intensely and the contact surface is reduced due to the presence of grooves on the surface.
Cleaning should be done with a small screwdriver with cotton wool soaked in pure alcohol or contact cleaner wrapped around the end. Contact cleaner is sold in auto stores.

In addition to cleaning, you also need to slightly straighten the clamping contacts on the phone so that they are pressed against the battery terminals with greater force.

There is no need to disassemble the tablet to remove the battery. Because on tablets it is connected by a soldered connection, and a problem with the hardware cannot occur because of it. And other iron problems are difficult to figure out and eliminate, especially for a person without special education.

The second way is to remove all software errors.

Very effective way, if it was done manually before, not through standard update. But this method will not help if you climbed into the root pre-installed applications or operating system, and remove these software partially or completely. Then only installing a licensed Android OS will help.

Try to do hard reset. This procedure, perhaps, will fix the problem when the android turns off by itself.

Turn off your phone or tablet and enter the “Android system recovery” menu ( Android system recovery).

To do this, you need to use the following key combination:

• For tablets, the key combination is as follows: you must simultaneously hold down the power off and volume down keys (for some models, volume up) for 10 seconds.
• For phones, the key combination can be similar to a tablet or like this: you must simultaneously hold down the power off, exit to the main menu (or camera) and volume down (or volume up) keys for 10 seconds.

In general, the key combination is unique to a particular brand.

When working in the “Android System Recovery” menu, use the following prompts on the screen: highlight – this is the key for moving through the menu; select – key for selecting a menu item.

In this menu you need to move to the item “ wipe cache partition" "and select it. Next, move to the “reboot system now” action confirmation item and select it. After this, the device will turn on again.

If the described action with deleting cache memory data did not help, then reset to factory settings. But, at the same time, personal data stored in internal memory devices. To do this, in the system recovery menu, select “wipe data / factory reset” and confirm the action.

In the end, if using these two methods you cannot fix the glitch in which your Android turns off, then contact a specialist repair shop.
