My laptop is in loop of turning on and off automatically?

Hi @reetik

Does it also do this when the charger is connected to the laptop?

Try a 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.

Here’s the hardware maintenance manual for the laptop that will help. It shows how to remove the main battery and also how to get to the systemboard so that the RTC coin cell battery can be removed.

Whenthe RTC battery is out check its voltage. if it is <2.5V DC or if the battery is >4-5 years old, replace it. Usually it's a CR2032 battery available most everywhere.

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

Reinsert the RTC coin cell battery on the systemboard, (+ve side up as marked onthe battery) re-assemble the laptop, re-insert the main battery, connect the charger to the laptop and try to start it.

If it starts, there may be a message about the date and time being incorrect. This is normal as the above procedure has reset the BIOS back to its factory defaults. Once the date and time have been adjusted, the message won't appear the next time the laptop is started. Any user defined BIOS settings that have been altered by you to suit your particular requirements will need to be changed back also.
