How to stop autostart automatically when PC is connectd to power?

Hi @sergefadhili

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

Here’s the procedure:

a). Turn off the laptop if it is on and then disconnect the charger from the laptop if connected.

b). Remove the main battery from the laptop

c). Remove the RTC coin cell battery from the motherboard.

Here’s the maintenance and service guide for the laptop. Go to p.39 and p.55 to view the procedure to remove the main battery and the RTC coin cell battery, respectively.

When the RTC coin cell battery is removed measure its voltage. If it is <2.6V DC replace it. If it is >5 years old, replace it anyway. The battery type number should be stamped on the battery itself CR2032 perhaps? Alternatively if you can't source one locally e.g. supermarkets, the part number is 449137-001. Search online for part number only, to find suppliers of the part.

d.) Reinsert the RTC battery (or its replacement - remember +ve on top as seen on the battery).

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

f.) When the laptop is completely re-assembled, connect the charger and check if it just charges the battery and doesn't turn on

If it only does this, allow the battery to fully charge and then try turning it on with the Power button.

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.
