Laptop will not power on

Hi,

Try a full power refresh in case it is a corrupted BIOS and check if that resolves the problem.

I realize that you said that you “… have tried the 30 second power button reset and no luck.” but sometimes it is necessary to remove the RTC battery (Real Time Clock) from the motherboard as well, to reset the BIOS back to its default state.

Here’s the procedure:

a). Disconnect the charger from the laptop if connected.

b). Disconnect the main battery from the motherboard.

c). Remove the RTC battery from the motherboard.

Here’s the maintenance and service guide for the laptop. Go to p.77 to view the necessary pre-requisite steps and then the procedure to remove the RTC battery. Unfortunately with your model you will have to remove the motherboard to access the battery.

When the battery is removed measure its voltage. If it is <2.6V DC replace it. The battery type number is printed on the battery. It may be a CR2032 which is commonly available everywhere

d.) Reinsert the RTC battery (or its replacement).

e). Reverse the above steps to re-assemble the laptop.

f.) When the laptop is completely re-assembled, connect the charger and try to turn on the laptop.

If it starts OK there may be a message about the date and time being incorrect. This is normal as the BIOS has been completely reset back to its default settings. Once the date and time have been adjusted the message won’t appear the next time that the laptop is started.

If you had previously changed any user defined settings in BIOS to suit whatever specific hardware configuration that you had for the laptop, then these will have to be set again.
