Hi @stanleymcdonald

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). Remove the main battery from the laptop.

c). Remove the RTC battery from the motherboard.

Here’s the maintenance and service guide for the laptop. Go to p.5-5 and p.5-28 view the necessary pre-requisite steps and then the procedure to remove the main battery and the RTC battery.

When the RTC battery is removed try to measure its voltage. If it is <2.6V DC replace it. The part number is 418880-001, (battery only you don't need the whole kit as shown in the manual). If you search online using the part number only, you will find suppliers of the part.

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

e.) Reconnect the RTC battery (or its replacement).

f). Reverse from Step b). above to re-assemble the laptop.

g) 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.
