My laptop is not opening but keypad light is turning on and off

Hi,

Try a full power refresh and check if that resolves the problem.

Here’s the procedure:

Disconnect the charger from the laptop.

Remove the main battery from the laptop.

Disconnect the RTC coin cell battery from the motherboard.

Press and hold the laptop’s Power On button for a full 30 seconds and then release it.

Reconnect the RTC coin cell battery, re-assemble the laptop, re-insert the main battery, connect the charger to the laptop and try to start it.
