My laptop screen remains black when it boots up. There is no any message on the screen or any error sound from the laptop however the screen stays black. This problem happened after installing new windows update.
When I boot the laptop up, everything seems to be working properly, CD ROM light is flashing, fan is working but I have no Idea why the screen remains black as if it doesn't receive power. What I have done so far:
- Bois rest. I thought there might be some errors with bios so I took the small battery out on the motherboard for few mins.
- connecting external Monitor to check if the laptop screen is gone.
