My laptop is not working properly

Hi @ibrahimfar43769

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.

c). Remove the RTC battery from the motherboard.

Here’s the maintenance and service guide for the laptop. Go to p.50 to view the necessary pre-requisite steps and then the procedure to remove the RTC battery from the motherboard.

When the battery is removed measure its voltage. If it is <2.5V DC or if the battery is >4-5 years old, replace it. The part number is N15765-001 (supplier examples only).

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

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

f). Reverse the above steps 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.

It could be a hardware issue—maybe the screen, RAM, or motherboard. First, try holding the power button for 10–15 seconds to force a shutdown, then turn it on again. If that doesn’t help, remove the battery (if possible), unplug it, and try again. If the screen stays black, it’s best to get it checked by a technician.

Perform a hard reset

Turn off the laptop completely and if it's on, press and hold the power button for 15-20 seconds until it shuts down.

Also you can do basic Checks and Hard Reset by:

Listening to the Fan when you press the power button, do you hear the fan spinning, hard drive activity a soft clicking this tells you if the laptop is getting power and some components are attempting to work.
