Make and model of your laptop? An SKU would help us two fold. What OS are you working with? Have you tried disconnecting from the wall, disconnecting the battery from the laptop then removing the sticks of ram, ad pressing and holding down the power button for 30secs to discharge the laptop's residual power?

Hard to say if LCD will need replaced or it's a driver or OS problem. I would start by hooking up another monitor and seeing what you can find out about your system.

Does the display stay black until you power cycle the laptop?

i have followed your advice. disconnected from main. disconnecting the batter cause the time and date to out of sync. unable to remove RAM since its built in. discharged the residual power. i even removed every peripherals

what happened then was DPC Watchdog Violation stop code error. blue screen. then the wifi hardware. was not detected.

what usually happen it would just black screen. power running. connected to external display via HDMI. no signal detected.

Stick to one thread please, unless you want to create spaghetti brains for yourself and the community members trying to assist you.

Try and see if you can remain in BIOS for 30mins. You might want see if you can enter Safe Mode and remain there, if nothing happens, backup all mission critical data and then you should contemplate reinstalling your OS after creating your bootable USB installer for Windows 11.

I asked for the make and model of your laptop, which could've come off the sticker under your laptop(or on the laptop's box/packaging).

this is not helpful at all. calling me spaghetti brain is does not solve the issue.
please check my history. i did posted this question in Februar 2024. how long more do i have to wait? February 2025?

i am not able to hold into BIOS as the laptop would freeze at startup. black screen. temperature is high at 80c on idle. DPC Watchdog violation.

I suspect its a motherboard or MOSFET? definitely not LCD issue. i did a clean install Windows 11. using an external display via HDMI it says, no signal detected.

black screen. fan is running. screen stay black until i force power shut down
