Lenovo notebook U31 70 battery damage must be replaced? Or is there a solution

1. First of all, check whether the battery charging is disabled in the laptop battery settings, and some laptop battery management software also has the function of disabling charging, you can check it;

2. It may also be because the battery has been put for too long and has not been used, resulting in poor contact, it is recommended to open the laptop to clean the dust, unplug the power cord and battery, and it may also be solved.

3. If there is no problem with the check settings, then most of the problems with the internal control circuit or battery cell of the notebook win7 system need to be repaired.

4. When some laptop batteries have been used for a long time and are over-discharged, resulting in 0% of the available power supply has been turned on and not charged, and it will be repaired later, even if it is repaired, the battery life and life will not be long, it is best to buy a new laptop battery to replace it.

The keyboard is out of order. It can be connected to an external mechanical keyboard.

The keyboard is divided into membrane ordinary and mechanical keyboards. Ordinary keyboards have a shorter lifespan.

Each key of the mechanical keyboard is an independent mechanical switch, and the switch is controlled by a metal spring, so it will have a longer life than the membrane keyboard, and there will be no aging after a long time. I use a Rapoo V500S mechanical keyboard, which has been durable and very good.

Adding memory has nothing to do with hard disks, just adding a memory module.

Whether the memory can depend on whether the motherboard has an empty slot, the same as the hard disk.

It's that the hard drive is too small! It's not that the memory is too small! You're confusing hard disk with memory!

If it really doesn't work, just change one and change that one, it should be enough for dozens of dollars.

Hardware problems, please return to the factory for repair, but ** is a bit expensive, but the advantage of returning to the factory for maintenance is that there are original materials, outside maintenance is cheap, but there are no raw materials, are repaired with alternative materials!
