Hi,

I've got BIOS crash and now my Laptop is like a brick (fans and Video card indicator work but screen is dark). When i tried to start Laptop I've got BIOS window with errror message related with UEFI. I launched BIOS reset to defaults and after it laptop just switched off. When I press power button it starts but screen is dark.

Can you please advise what can be the reason and what to do?

1. Unplug the PSU (Power Supply Unit)

2. Remove the Battery

3. Remove the small CMOS Battery cable for about 30 seconds

(Mostly located under the keyboard. For the exact location please refer to the respective Service Manual)

4. Repeat steps in reverse order

5. Be a bit easier on your settings next round.
