I have hp pavillion M6 laptop. When I boot it , it normally starts, display, keyboard are working good but after 5-10 sec display goes very dim that I can't see anything and no key works with keyboard. However external monitor and keyboard works well.
Same thing happens with recovery screen, bios setup , safe mode etc. At first everything works fine but after a while screen and keyboard are not responsive. I have windows 10. Checked ram by replacing then CMOS battery voltage is accurate. Nothing works. Please help me.

If you hooked up an external keyboard then control the brightness of your laptop from there or use windows's built in brightness control.
