Not turning on starts but not turning on

Hi @harshkumar70815

Try a full power refresh in case the BIOS has become corrupted and is preventing a normal start i.e the laptop is not passing POST (Power On Self Test)

Here’s the procedure:

a). Disconnect the charger if connected.

b). Disassemble the laptop and disconnect the main battery from the laptop. You don't have to remove the battery just disconnect the battery cable form the motherboard.

c). Disconnect the coin cell RTC battery from the motherboard. Here’s the maintenance and service guide for the laptop. Go to p.49 and p.54 respectively, to view the procedure to disconnect the main the battery and the RTC coin cell battery.

d). Press and hold the laptop’s Power On button for 30 seconds and then release. This will restore the BIOS back to the factory default settings.

e). Reconnect the RTC coin cell battery

f). Reconnect the main battery, reassemble the laptop, and connect the charger.

g). Switch on the laptop and check if it starts OK. There may be a message on the screen about the date and time being incorrect. This is normal as the BIOS has been reset. Once the date and time have been corrected, the message won’t appear the next time that the laptop is started.
