my computer turns off when trying to wake from sleep

Hi bnour,

I would suggest you to update the BIOS on the computer. Please enter your service tag # on the link below, then download the BIOS required onto the system and install it.

Also, I would suggest that you run the diagnostics on the computer by following the steps mentioned in the video below and check if there is any issue with the hardware on your system.

Hi,

I try to update the BIOS, but there is no new version, so I reinstall the same version in order to get better sleep mode.

And I've noticed that every time I try to optimize my system with drivers and updates, the same drivers appears as shown below, but I already have installed them long ago. Is it an issue?

I also run the diagnostics on the booting.

I will see if the problem will never happen again.

Thanks.
