Hi @peterphiri

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). Remove the main battery from the laptop.

c). Disassemble the laptop and remove the coin cell RTC battery from the motherboard. Here’s the maintenance and service manual for the laptop. Go to p.26 (34 of 119 pdf) and p.62 (70 of 119 pdf) to view the procedure for how to remove the main battery and the coin cell battery, respectively

When the coin cell battery is removed from the laptop, use a DMM (voltmeter function) to measure the battery’s voltage. If it is <2.6V DC or if the battery is >4-5 years old, replace it. Search online for 616073-001 to find suppliers that suit you best.

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 coin cell battery (+ve on top as marked on the battery)

f). Reassemble the laptop, reinsert the main battery 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.
