Q: I have a problem with my HP Compaq 615 laptop. I use it every day at school, and 6-7 times a day usually the screen brightness turns down in 2 seconds, and then turns to normal again. Just like if you pull the power from the machine, and Windows automatically turns it down.
Lately it's just been happening about 2 times a day. It's still annoying though.
Could this be a software related issue or something that can be fixed at home?
I tried updating my BIOS to latest versino.
I tried rolling my gfx driver back. Tried updating it once again.
It's still happening though.
Any help would be much appreciated.
A: 1)installed Windows 7 Pro on the machine. Shouldn't any trouble though.
2) change a good backlight or inverter to laptop
