My laptop isn't restarting after a power surge

after a sudden power surge, my laptop isn't restarting. while i try to restart it shuts down but indicator led like mute, volume controller doesn't go down and the laptop doesn't start again. i have tried to remove adapter and battery, but nothing happened. removing and re inserting cmos battery made the computer start, but automatically. whenever i connect my adapter to laptop, it automatically starts. if i just start the laptop and simply shuts down, there is no problem. problem is when i try to restart.

it doesn't restart and doesn't bootup unless i reinsert the cmos battery.

so what should i do?

The CMOS battery needs to be left in. It maintains the necessary configuration settings in BIOS for your laptop to work properly.

Re-install the CMOS battery and leave it there (make sure that it is installed the correct way), and then try the following:

Remove the main battery pack and the adapter from the laptop.

Press and hold the power button on the laptop for 15 seconds and then release it

Reinsert the adapter (leave out the battery pack at this stage) and switch it on. Turn on the laptop. You may get a message about the date and time due to the CMOS battery being removed previously. If the laptop boots into Windows, allow it to boot all the way to the Windows desktop. Once there, shutdown the laptop in the normal manner.

When the laptop has shutdown, turn off the power to the adapter, reinsert the battery pack, turn on the power to the adapter and then turn on the laptop.

Allow the laptop to boot all the way to the Windows desktop. Once there check to see if the battery is charging (or whether it is fully charged). If it is charging, allow it to fully charge before either shutting down the laptop or disconnecting the adapter.
