Pc does not show any information

Hi @mvssiiz

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). Disconnect the main battery from the motherboard. You don't have to remove the battery, just unplug it.

c). Unplug and remove the RTC battery from the motherboard.

Here’s the hardware maintenance manual for the laptop. Go to p.35 and p.46 to view the necessary pre-requisite steps and then the procedure to disconnect the battery and to disconnect and remove the RTC battery respectively

When the RTC battery is removed measure its voltage. If it is <2.6V DC replace it. The part number is 5B10R34404. 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 the above steps from Step. b). 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.
