1. The first situation is that the system displays an error, in this case, restart, or plug and unplug the AC power supply again [the pro-test is to turn off the computer, remove the battery, do not plug in the power supply, and then install the battery to turn on, and then the key, unplug the battery, plug in the power supply, and turn on to see the effect].

2. The second situation is that the battery and AC power supply are normal, and the battery power is less than 100%, but the battery is still displayed that the battery is not charged, which is a battery protection technology, and its effect is to effectively reduce the battery loss caused by unnecessary battery charging times due to frequent repeated charging and reduce the battery life. Different notebooks may set different charging percentages, and this is automatically controlled by the notebook.

The battery is aging, and the battery has not been unplugged when connecting to the power supply, so that the battery continues to charge, and when the power supply is disconnected, it will occur because the battery is seriously aging, and the battery will be low instantly.

It may be a poor contact.

If the battery still can't be charged, 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, do not open it by yourself or try to repair it, there is a certain risk of wide lift, it is recommended to take it for repair.

Check to see if there is too much charge in the battery. I've had this problem before, it seems to ask me to install the battery, connect the power supply externally, leave it on for a day, and then turn it on again at night. It seems to have been turned on later, but the battery cells are not easy to use, and it can only be turned on for five minutes, and then it will automatically sleep.

The Lenovo notebook can't be turned on, you can check it according to the following methods.

1) First remove the battery, unplug the power plug, press and hold the power button for about 5 seconds, then plug it in to see if it can be turned on, if it still can't be turned on, continue the following steps.

2) Remove the battery, unplug the power plug, and open the back cover screws with a Phillips screwdriver. There is an opening on one side of the cover, and the cover can be removed by gently cocking it along the opening with a screwdriver.

3) After removing the cover, find the memory module, and use a screwdriver to gently remove the clips on both sides of the memory module, so that the memory module can be released. Gently remove the memory module and wait a few moments before putting it back on.
