Hi @randomcake

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

Here’s the procedure:

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

b). Open the laptop and disconnect the main battery from the motherboard.

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

Here’s the service manual for the laptop. Go to p.21 and p.30 to view the the procedure to remove main battery and the RTC coin cell battery.

When the RTC battery is removed measure its voltage. If it is <2.6V DC replace it. It is a CR 2032 Lithium non rechargeable battery that is commonly available most everywhere e.g. supermarkets.

d). Press and hold the laptop's Power button for a full 30 seconds and then release it.

e.) Reinsert the RTC battery (or its replacement). Note the orientation of the battery - +ve is on top as marked on the battery

f). Reconnect the main battery and reassemble the laptop.

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.

I tried turning my laptop again the day after and it worked just fine, but the next time I tried it, it didn't.



If nothing happens when you press the power button then it could be an intermittently faulty power button perhaps.

If you have a DMM (digital multimeter) you can check if the button has continuity through its contact when it's operated.

The service manual I linked shows how to remove the power button board so that you can access it and test if it is OK -see p.57.
