Lenovo laptops won t charge, why can t Lenovo laptops charge?

Dear Lenovo users, hello:

It is recommended that you try to update your power management driver, and please try to release static electricity.

Static electricity release method: You can try to unplug all external devices (including power cords and batteries) from the host, press and hold the power button for 30 seconds, and then connect all external devices to power on for testing; If your laptop has a built-in battery, there will be a reset hole, use a straightened paper clip to insert into the reset hole, press it for a few seconds, and turn it on for testing.

What does the battery icon show, first try to use the adapter directly without the battery to work, if so, prove that the adapter is normal;

The rest is the battery problem, go order a new battery and come back and replace it.

There are several reasons why Lenovo laptop batteries won't charge:

1. The power mode is set with the best battery maintenance, and when it reaches 50%, it will not be charged, and the power mode can be changed by directly modifying it.

2. The battery is damaged, resulting in the inability to charge, and needs to be sent to the after-sales service station for testing and maintenance.

Lenovo notebook charging precautions and battery maintenance are as follows:

1. For lithium-ion batteries, it can be used directly without activation.

2. Do not expose the battery to water or other liquids.

3. Please do not unplug the external power supply during the charging process of the battery until it is fully charged.

4. If the battery has been damaged, or if the battery is found to be leaking or there is a build-up of foreign objects at both ends of the battery, please stop using the battery.

5. If the battery is not used for a long time, its performance may be reduced. Do not store the battery separately for more than 1 month, and ensure that the battery is charged every 1 month or so.

6. Do not completely discharge rechargeable lithium-ion batteries, and do not store these batteries in a discharged state.

The reasons and solutions for the failure to charge the Lenovo notebook when plugged in are as follows:

1. The battery protection mode causes it to be unable to be charged. If a "battery protection mode" is enabled, the power management software will prolong battery life by disabling charging and discharging the battery when it detects the user's use of AC power. So, if you find that your laptop is not charging, you can first go to the relevant power management software, turn off the battery protection mode or check the no charging option, and if there is no problem with the hardware, the battery will be able to charge.

2. The hardware failure of the battery itself. Generally speaking, we can use restarting the computer and replugging the battery to tell if the battery still won't charge, you might as well install some hardware detection apps to get an approximate reference information about battery loss. If it is determined that the battery hardware is faulty, the battery will need to be replaced.

3. The power adapter is faulty. Power adapter failures are very rare, and there is no suitable self-testing method, so they can only be sent to the repair station for testing and replacement and repair.

You can try unplugging the power supply first, and then plug it in after a while to see if it can charge normally.

Some notebook manufacturers have battery energy-saving control charging software, see if there is such software on the machine, the software can set the value of the battery charge to how much.

If it is a hardware problem, there are several possibilities:

1. Battery failure, 2. Charging interface failure, 3. Motherboard failure.

Regardless of the cause, it is recommended to send the laptop and power adapter to the official after-sales service center together, and a professional maintenance engineer will do a detailed test to confirm the specific problem and its cause.

1. The charging function is disabled in the notebook battery management software;

2. Caused by the aging of the laptop battery or the lack of daily maintenance, the battery power is often used until it is exhausted, until the computer automatically shuts down. In fact, it is easy to damage the battery in this way;

3. Some users take out the laptop battery for a long time and put it away, which will also deplete the battery and cause the battery life to get worse and worse;

1. Check whether the battery charging is disabled, whether the laptop battery is disabled after the user settings, and sometimes the charging function is disabled by the laptop battery management software.

2. If there is no problem with the check settings, if the laptop battery has been used for a long time, and 0% of the available power has been turned on and not charged due to excessive discharge, if it is taken for repair, even if it is repaired, there will be a problem of battery life and not long life, it is best to buy and replace a new laptop battery.

3. If the battery is left for too long and is useless, it is recommended to open the notebook to clean the ashes and unplug the power cord battery.

4. There is a problem with the internal control circuit or cell of the battery of the notebook system, which needs to be repaired.

1.Poor contact of the battery contacts. 2.

The part inside the laptop that powers the battery from the adapter is damaged. 3.The power supply to the power supply is different from the battery power supply to the book, first of all, the battery power supply, the output of the battery is pure DC, very clean, directly connected to the DC transformer module, the voltage of the battery is neither possible nor need to be designed to be very high, but once the aging is too low, then the notebook can not start.

4.The internal control chip of the battery fails, causing the computer to "think the battery is full" and therefore not charging.
