Laptop Switches On Only When Power Plugged

Problem description:

The laptop switches on only when power plugged. When the laptop is unplugged and you press the power button, nothing happens.

Possible cause:

1. Bad battery.
2. Motherboard failure.

Possible troubleshooting steps and repair solution:

This is either a battery or motherboard-related problem.

1. Try reconnecting the battery. Remove it from the laptop and plug it back in. Test the laptop again. It’s possible that the battery is not making good contact with the connector on the motherboard.

2. Try replacing the battery with a new one. The battery could be bad. Even if the battery is detected by the operating system and appears to be 100% charged, it still could be bad.

3. It the problem still exists even after replacing the battery, most likely it is related to the motherboard failure. You’ll have to replace the motherboard or use the laptop just on AC power.
