Why my laptop is not turning on

Hi @khushrajgehlot

Try a power refresh and check if it resolves the problem.

Disconnect the charger from the laptop and then remove the battery pack from the laptop.

Here's the maintenance and service guide for the laptop. Go to p.30 to view how to remove the battery from the laptop.

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

Reinsert the battery and connect the charger and then check if it turns on OK.

If still no good, try a full power refresh and check.

Disconnect the charger and battery as described above and then go to p.51 in the service guide (linked above) to view the procedure to remove/replace the RTC coin cell battery from the motherboard. When the battery is removed, measure its voltage. If it is <2.5V DC or >4-5 years old, replace it. It is a CR2032 Lithium coin cell battery, available most everywhere, e.g. supermarkets.

Reinsert the RTC battery, (+ve on top as marked on the battery), reassemble the laptop and reinsert the battery and connect the charger and then check if it turns on OK.

If it turns on OK there may be a message saying that the Date and Time are incorrect. This is normal as the BIOS has been reset back to default by the procedure above. Once the D&T have been corrected the message won't appear the next time the laptop is started. Also any user definable BIOS settings that were changed by you to suit whatever operating requirements you had, will have to be changed back again also.
