1. The battery is displayed on the computer, is charging, unplugged, and the notebook can stand for a few minutes and the battery is too low. So that the laptop battery circuit board is normally available, this is a laptop battery replacement and repair prerequisites.
2. The laptop battery is generally one-piece assembly, there is no screw, can not be easily opened, the general use of violent dismantling or splitting and other methods. Use saws as little as possible and it is easy to short circuit. Use a knife to gently swipe along the seal line.
3. Do not cut the circuit board directly after the battery is disconnected. The battery to be bought should be welded first according to the state of dismantling the battery, and then the flying lead (connected with the original circuit board) should be used to ensure that the circuit board does not lose power. Because the power failure will trigger protection self-locking. Then there is no way to change the battery.
4. After the flying line is connected, slowly remove the old battery and reinforce the bold new battery connection. The battery can be easily replaced without losing power.
Precautions:
Laptop batteries are prone to ageing, reasonably using batteries, and not being overloaded for long periods of time, or stored at a loss.
The lead-in line must be used during battery replacement to ensure that the battery circuit board does not lose power. Power failure will lock.
It is best to match the internal resistance of the newly purchased battery. The oldness and the oldness should be the same. This will only last longer.
