What to do if your Lenovo tablet won't turn on or charge

Modern tablets have replaced laptops in terms of using a computer on the go. But sometimes tablets still malfunction and frustrate users. A situation can happen to anyone in which their favorite Android, for some unknown reason, turns off and does not turn on.

This article will be dedicated specifically to the Lenovo brand and I will look at the question of what to do if the Lenovo tablet does not turn on and does not charge.

I will tell you about some methods of how to find out the cause of the breakdown, and you will also know the actions that need to be taken to fix everything. In general, these tips are universal for all Lenovo tablets, so regardless of the model, you can apply them in your case. If the actions that need to be performed differ for different models, I will definitely mention this.

What are the causes of the malfunction?

First of all, we must find out why something went wrong. Once you understand why your device works poorly when you put it on charge, or stops functioning altogether, you can take steps to troubleshoot the problem.

If you disassemble the charging process into its component parts, you can personally diagnose the illness of your electronic pet. There is a difference between a tablet suddenly suddenly stopping functioning and a situation where the problem has long manifested itself as a periodic decrease in charging speed.

Remember, when the android still responded to being connected to a power outlet, did it charge slower than always? If so, you should first find out why it takes a long time to charge the tablet from your network, and whether there are problems with your outlet and wiring at home.

There is also a chance that you simply charged the device incorrectly. You can find out how to properly charge your tablet on the manufacturer’s website, but general advice is as follows: use exclusively “personal” charging; use only proven sockets and electrical networks; Do not use the network during power outages (for example, during a thunderstorm).

If a nutrition problem appeared suddenly and did not manifest itself before, this reduces the range of possible causes. Problems may occur due to the following:

• battery;
• contacts;
• charger;
• network and network voltage;
• connecting the board to the display or the board to the battery;
• other problems (there can be a lot of them - it is recommended to contact the service center).

Software

Often, Lenovo Android devices take a long time to charge and then quickly discharge due to constantly running programs that use a lot of energy. If this is the case, then you need to turn off all applications, Wi-Fi, Geolocation and Bluetooth while charging so that the device charges as quickly as possible.

Energy optimization

What can help fix the problem:

• Optimization programs: Clean Master, Smart manager, etc. They disable all existing processes that interfere with the optimal performance of gadgets.
• Do a factory reset through the Settings menu, using the number combination or pressing the Power keys, as well as the volume up and down controls at the same time.

Flashing Lenovo

Reinstalling the firmware helps. To do this, you need to connect your phone to your computer and follow the instructions:

1. Launch ROM Manager, connect a flash card with custom firmware.
2. In the utility, select “Install ROM from CD card” and specify the path to the file.
3. Click on “Save current ROM”. This will allow you to roll back the firmware to the old one in the future if you don’t like the new one.
4. Select “Reboot and installation”, agree to the action and wait for the program to restart the smartphone and update the firmware.

All of the above steps usually take no more than 40 minutes, but to avoid permanent breakdown of the device, you should still visit the official service to update the software.

Contacts are dirty or inputs are broken

The easiest way is to check the charging contacts as well as the inputs on your device. This is also the most common cause of charging problems: the inputs can become clogged with dust, dirt, and water. Carefully inspect them together with the charger contacts - it will be immediately clear if this is the reason that interferes with the recharging process. What to do in this case, I think, is already clear: you need to carefully clean the contacts from dirt and dust. If this fails, it is better to immediately contact a service center - this will be much more useful than harming the contacts by cleaning too thoroughly.

Replacing the power connector

The most common reason for the inability to fully charge the Lenovo K5 is a weak power connector. Sharp tugs on the charger cord, careless operation, or using the smartphone while charging damage this particular element of the device. To restore it, as a rule, it is necessary to install a new connector.

It is unlikely that you will be able to carry out the replacement yourself. In addition to the power connector, you will need a soldering iron and certain skills.

You can determine the need to replace the charging socket as follows:

• Visually inspect the connector: protruding contacts or a broken tab are a sure sign;
• The device “does not see” the memory when it is working properly;
• If the charge enters at a certain angle, it means that the soldering has come off in the area of ​​​​the contact and the system plate.

The power connector is replaced in several stages:

• The device is carefully disassembled, the system board is removed, cables and cables are disconnected;
• The removed motherboard is mounted on a soldering stand;
• Then, with a soldering iron, the connector fastening areas and, first of all, the contact area with the “motherboard” are covered;
• After preparation, the non-working charger connector is heated with a soldering hair dryer at a temperature of 400 °C;

• After the flux boils, the old connector is removed;
• Next, the soldering area and the new charger connector are additionally lubricated with flux, the connector is mounted and sealed in the desired place;
• The smartphone is assembled in the reverse order;
• At the final stage, the functionality of the new power connector is checked.

How to find out if the problem is in the battery and how to fix it

A battery is a piece of hardware that is responsible for accumulating and storing electrical energy in a device. Naturally, if there is something wrong with it, the device will not be able to accumulate and store energy. This may be why your tablet won't turn on or charge. This is not always easy to determine.

Most often, incorrect charging occurs: perhaps you connected the tablet to the network during a thunderstorm or normal power surges? Or often brought it to full discharge (it is not recommended to let lithium-ion batteries reach <10%). Try to remember such actions and if this really happened during use, you will have to contact the service center for help in replacing the battery. In the future, try not to repeat the mistakes in using chargers.

What to do if the Lenovo battery does not charge

1. Before starting the recovery process, turn off the power to the device and remove the contact from the corresponding port;
2. Then disconnect the storage element. Laptops that allow you to remove the battery will require sliding one or more locking devices holding the cell housing;
3. Press and hold the device's start key for approximately 60 seconds;
4. Then connect the charger input to the laptop computer, then plug it in. Do not connect the battery;
5. Start your laptop, then go to the BIOS (Basic Input/Output System). For devices from Lenovo, the transition is carried out by pressing the F2 key while holding down the function button;
6. In the shell, reset the settings to factory defaults, then save and exit. Usually all this is in the Exit section. (Items “Restore Defaults” and “Save and Exit”;
7. Then turn off the power to the device by holding down the power button for a few seconds;
8. Disconnect the charger and reattach the battery;
9. Reconnect the port from the power supply and connect to the network;
10. Start the laptop;

If the method helped, then when you start the operating system, a symbol indicating successful connection and restoration of battery capacity will appear in the notification line.

If the procedure does not help

Otherwise, the problems may be in the software preinstalled by the manufacturers. The type of utilities that monitor the charge level can also lead to problems with the operation of the laptop.

Mainly due to modes that make it possible to carry out battery operation with minimal loss of battery capacity.

With certain settings, you may have problems reaching the maximum charge level.

To find the problem, examine the warning line. If it becomes impossible to charge the Lenovo battery, changes in the battery symbol in the tray are also possible.

If it is present, it is advisable to uninstall it from your laptop. All modern operating systems allow you to independently regulate and optimize the use of the device. Because of this, using utilities from developers or other manufacturers becomes useless.

the Lenovo battery still does not then the reason may be a malfunction of the charger. In this case, you need to check the power supply. The easiest way to do it is this:

1. Turn off the laptop, then unplug the power supply;
2. Disconnect the Lenovo battery;
3. Connect the device to the network directly;
4. Start the laptop;

If the laptop does not start after startup, you will need to replace the power cord or power supply. The problem may also be due to insufficient power from a damaged power supply. It is advisable to purchase a new device to restore capacity.

Lenovo battery does not charge - incomplete charge

A characteristic manifestation of a failure is that the Lenovo battery is not able to fully restore its charge level. There is also an inherent problem with reduced battery life. If the battery on a Lenovo laptop runs out quickly, then the problem may be in a worn-out state.

To ensure that the battery is in good condition, you will need to check the condition of the device. To do this, you can use the free Battery Care programs or analogues for the Windows operating system, and Battery Health for Mas OS X.

After downloading and installing the application, you need to evaluate the status in three main aspects:

• Declared power is a parameter corresponding to the capacity of the battery at the time of release;
• Maximum power – a value indicating the current highest level of capacity;
• Battery wear is a percentage of the current damage to the maximum charge. If the value is high, the Lenovo battery will need to be replaced.

Failure to fully restore the maximum power level can also occur due to errors in determining the charge level. In this case, you will need to calibrate the battery.

At high levels of wear, the storage element will need to be replaced. The manufacturer advises purchasing only original batteries.

It is possible to replace the storage element yourself. On netbooks there is usually no option to disconnect the battery. Therefore, you need to visit a specialized service center.

Lenovo battery does not charge - rapid loss of capacity

If no significant wear is observed, the fault may lie with one or more background applications. At the same time, the operating time from the storage element is significantly reduced.

However, the battery remains undamaged. The application does not allow you to switch hardware for working with data and wireless networks to saving mode.

To make sure there is a problem, launch the task manager and examine the list of executing processes. If necessary, an additional analysis of CPU time costs is required.

Based on your analysis, disable and remove unnecessary software. Or remove it from the automatic download list. Due to this, the battery life will significantly increase.

If there is a problem with charging

Charger failure is another common cause of problems. It has already been mentioned that proper charging involves the use of a native charger for the Lenovo tablet. If you use someone else's, don't be surprised if it doesn't work as it should and the tablet suddenly stops charging.

If you do everything correctly, and the original charger for your device does not function, you need to inspect it for damage. The cord may also be in poor condition and thereby affect the power supply. In principle, even if the charger works normally in a damaged state, it should be replaced; if nothing happens when connected to the device, the damaged items should definitely be replaced with new ones.

Battery fault

Lenovo smartphone batteries have a limited charge-discharge cycle (about 300-400). For this reason, after a couple of years the capacity drops significantly, down to zero, and the battery is not able to start the system.

The easiest option, if there is no visible damage to the case, is to replace the battery with a new one. It is advisable to take the original one, since non-original ones do not “work” at full capacity.

Often the battery “swells”; in this case, you must immediately buy a new battery, otherwise everything could end in a fire. Li-Ion elements are deformed and fail with minor mechanical damage.

Special programs

In order not to suffer manually, we use special programs for calibration. For example, Battery Calibration, which is very easy to use:

1. Download the application on Android and launch it.
2. We connect the gadget to charging, bring the charge level to 100% and leave everything in this position for another 1 hour.
3. We go to the program menu, select “Calibrate” and wait for the process to complete.
4. Disconnect the charger and reboot the smartphone.

Battery calibration

Battery calibration is a procedure that allows you to manage the “memory effect” on Lenovo smartphones and other Android devices. As you know, with a constant incomplete charge, its capacity drops over time, and in order to restore everything, you should use this method of bringing the part to its optimal condition.

If your gadget charges very slowly, you should try calibrating the battery. This is done like this:

1. We discharge the device until it turns off on its own.
2. We take out the battery for 2-3 minutes, then insert it again. If it is built-in, this action is skipped.
3. We charge the device completely. Experts recommend charging for 8 hours.
4. We take out the battery again and leave it for 1-3 minutes, after which we put it back and turn on the phone.

If your mobile phone does not charge, you must use other methods or take it to a service center to find out the problem.

Check connections between the board and modules

There is a possibility that the display has simply moved away from the board. This means that it is not connected to the rest of the hardware and, of course, will not work. It is impossible to diagnose such a problem with a guarantee, but if you happen to drop your tablet on the floor, after which it turns off and does not respond to the power button, you probably have exactly what I am describing. This is a fairly serious problem, so without specialized knowledge you will not be able to fix it - you need to contact a service center.

Battery replacement

Some Lenovo models initially have defective batteries. The reason why Lenovo does not charge is most often associated with this very reason. It's worth believing that your K5 may suffer the same fate. To avoid becoming the “lucky” owner of a faulty device, open the back cover and check the surface of the battery.

If you find swelling or any other deformation, immediately ask to replace the battery. A non-removable battery can be checked for defects in another interesting way. Place the gadget on a flat part of the table and rotate it around its axis. A device with a swollen battery will spin perfectly - like a boiled egg.

A new battery can operate effectively for 2 years, after which it must be replaced. Although this period is conditional and primarily depends on the number of charge-discharge cycles. If your smartphone is no longer young, it will be difficult for its battery to hold a charge.

If a malfunction occurs very early, you must familiarize yourself with the manufacturer’s warranty: a free battery replacement is also possible.

If the reason that you cannot charge the phone is still due to a faulty battery, then it must be replaced with one recommended by Lenovo. Batteries from other manufacturers are much cheaper, but they may not work as efficiently as the “original” battery.

Network problems

It is likely that there is nothing wrong with your tablet and there is no point in taking it for repairs. In this case, if the voltage in the house reaches very low values, the device simply will not charge. It will not turn on because it is 100% discharged, and it will not charge.

Pay attention to the socket - it may be damaged and not conduct current. Don't go there on your own!!! If you need to check the voltage in the network and the serviceability of the sockets, it is better to contact an electrician or at least a familiar engineer.

Faulty charging connector

If the charger is connected to another gadget (you can connect it not only to Lenovo) and charges it, most likely the problem is in the micro USB socket. It needs to be replaced by a specialist, but first make sure that the charging cable and power connector are compatible. The fact is that seemingly identical chargers are sold for all smartphones, but in fact some plugs may not fit.

The problem may lie in the charger cable: even visually, the entire cord can be damaged from the inside, and then energy will not be supplied through it.

Diagnostics and cleaning

When the battery does not charge, this often happens due to temporary wear of the part itself or faulty contacts. The latter are easy to check:

• We take a flashlight and direct the light into the connector of the device for charging.
• If oxidation is visible on the contacts, remove them using a piece of cotton wool soaked in alcohol. This must be done carefully and only after turning off the device.
• If the contacts are damaged, it is better to trust a specialist, because to restore them you need to use a soldering iron.

Signs of a virus infection

The main symptom when software is infected with malware is the absence of an indication. It can also freeze constantly, and if previously the battery lasted two days, then after getting a virus it will be discharged in 5-12 hours (i.e. a very long time).

To troubleshoot problems, you need to scan your phone using an antivirus program. If infected files are detected, they will be deleted automatically, and if this is not possible, you will have to clean the system manually, removing the application itself that contains the viruses.

In the modern world, a smartphone is an indispensable thing, so when your favorite gadget takes a long time to charge or does not turn on at all, this becomes a whole problem, especially if it is a new phone.

First of all, we think about how to charge our gadget, especially when we are in a hurry and are looking for the causes of problems in the phone, but before that we should carefully inspect the accompanying equipment:

• Socket - if the wiring is old or there are some other problems with electricity, then this may well explain why the gadget is sometimes charging or not;
• Charger - check its integrity, it may be damaged;
• Incompatibility of the charger with the gadget - if the inputs are similar, this does not mean that the charging device is suitable for both models of smartphones.

If you are convinced that you do not have any of the above problems, you can move on to studying the phone itself. We will look at the most common reasons why the phone does not accept charge.

When the phone is charged only from the computer, but the smartphone is turned on and working normally, it is worth checking the charger. But if charging is in order, but the smartphone does not see it or writes that charging is in progress, but in fact it is not, there is a malfunction in the phone.

In some cases, flashing the gadget's firmware or replacing the input helps, but only a professional can do this after examining the device and identifying the problem.

It happens that the phone shows charging, but does not charge, and even after several hours of recharging, the battery remains at zero. Or, if you do not charge the phone for a long time, the battery does not accept a charge. In both cases there may be several reasons:

• The charger does not charge;
• The phone battery is faulty;
• There are many applications and other services open.

If the problem is with the charger, the gadget detects the charger, but due to technical faults it does not charge. This situation is probably familiar to iPhone owners, since the cable becomes damaged due to frequent use. Try replacing the wire, maybe that's the problem.

If the problem lies in the battery, you will have to buy a new one or even contact a specialist, since smartphone models such as Samsung Galaxy S6, LG Optimus Vu, HTC One X have a built-in battery, which means that you cannot replace it yourself.

The last option is very rare, but still occurs, especially if you are the owner of a DNS or Fly brand smartphone. In this case, you just need to close all programs, in particular Wi-Fi, the Internet and your favorite games, and then leave your Android alone while it is charging. If the indicator shows that the charge is coming, you can congratulate yourself, you have just fixed the problem.

You are familiar with the situation when the phone is working and charging is in order, but for some reason the smartphone does not respond to the device when connected to the network. You don’t even know what to do anymore, since the phone doesn’t charge for a very long time, but the reason for this may be trivial.

From time to time, dust gets into a cell phone with a removable battery, especially for older Samsung models. If you don't clean the inner surface, dirt accumulates, creating a layer that prevents the contacts from connecting normally, which is why the phone won't charge. Try removing the battery, then clean it and the inside of the case with a cotton swab. Also pay attention to the “teeth”; if they are slightly bent, correct this using a match, but act carefully so as not to damage the contacts.

When the phone does not charge from the charger, the reason should be sought in the charger or in the gadget connector. In this case, it’s very easy to find out what’s really not working, just connect your mobile phone to your PC or use a universal frog charger, but using it every day will be problematic, since you’ll have to turn off the phone every time and take out the battery. Another way to charge your phone from an external battery, but this is also not an everyday option.

Not everyone knows why charging goes in the opposite direction, and the phone does not take charge, but seems to give it away. Faced with such a situation, many are simply perplexed. The reason for this unusual phenomenon is simple - a failure in battery calibration, this happens from time to time with Lenovo phones, but do not panic, because the problem can be solved very quickly.

To eliminate the anomaly, you first need to discharge the battery to such an extent that the smartphone turns off on its own. After that, remove the battery for a couple of minutes and put it back into the phone. Connect the gadget to the charger, but do not turn it on while the charge is running.

If your smartphone was charged all night, but was not fully charged or the readings were no more than 1 percent, then the problem lies in the battery. Of course, for the first time you can even charge the phone to 100 percent, but not only will the process take a lot of time, but the gadget will also be discharged in literally a couple of hours, if not earlier.

In this case, you have only one option - buy a new battery and continue to safely use your irreplaceable gadget.

You can figure out the problem yourself, but if you are unable to find out why the phone is not charging and you have tried almost all of the above methods, it is best to take your smartphone to a technician, because only a specialist will be able to determine the true cause of the malfunction.

Problems with charging a smartphone can be called one of the most unpleasant. If the Android phone does not charge, the power goes on, but the charge does not increase, the owner has many questions, and often such situations lead to inconvenience of use and the final discharge of the device. What to do in such cases, as well as the reasons for such problems, are discussed in our article. Another common problem is the charging socket becoming loose. This factor is influenced by careless operation, the habit of charging the smartphone on the go, as well as factory defects of the device. Replacing the connector will not take much time, but it is better to perform this procedure in a service center ="400″[/img]

Recommendations

To extend the life of your iPhone or Android smartphone, you need to follow these recommendations:

• Do not let the gadget fall.
• Do not discharge the battery too often (no more than once every 2 months) completely to 100 percent. It is ideal to keep the level from 20% to 80%.
• Do not abuse the use of a low-power universal charger, even a new one.
• Install anti-virus protection on your phone.
• Do not leave the device in the cold or heat (operating temperature from +3 to 45 degrees).

Firmware failure

Chinese Android smartphones - Xiaomi, Huawei, Meizu - use their own shell. Users often have access to administrator rights - they can install third-party firmware on the gadget. Unofficial firmware developed by an inexperienced programmer may affect the operation of the device. For example, the phone will only charge when turned off. This problem occurs because the charger begins to conflict with the firmware.

There are several ways to solve the problem:

1. Roll back to the official firmware version, which was installed by default.
2. Reset all smartphone settings to factory settings (performed in the gadget settings).
