Chosen Solution

Hello everyone please help me. My laptop shows no display when turning it on but the power led and charge is on the HDD is also spinning and the fans are ok too. Now before this mess happened, I change a setting in the bios to boot in CSM from UEFI and now the display wont show up no matter what key function i pressed. I also tried the remove the CMOS battery and left it for many hours with no good result. I dont know what to do anymore.

UPDATE: Good news. My laptop all of a sudden just turned on it’s display. All I did was a huge amount of patience while swapping the ram with its slots and voila it fixed it.

I am not sure what you mean when you say “. . .no matter what key function I pressed.” ??? What have you pressed - this is important ? Just enter BIOS and reset to UEFI.
