Hello,

I've been trying to get my HP envy laptop to work all day and to no avail. When I press the power button, everything turns on, but the display doesn't at all. No back light, nothing. I've tried setting up an external monitor, but all that displays on the monitor is a black screen with a cursor. I've read multiple forums and none of the solutions I've read have worked. I've tried resetting the bios, the CMOS battery, and I've tried getting "excess static" out of my laptop. I'm a student and desperately need my laptop to be functional before finals week.

Thanks

Hello Mdrjohnson,

Can you hear the laptop fan and hard drive working? If there's nothing showing either on external monitor nor display, but the fans are still working, the problem that you have may be due to the failure of the video chip. Sometimes, after much of a use and less cooling the graphics processor which is responsible for video signal transmission get unsolders, the thermic paste goes away and it gets unsoldered, therefore the screen doesn't show anything. If you possess knowledge of notebooks' hardware you can change the paste yourself by opening the laptop and check if the chipset that is next to the processor has got unsoldered or you can bring your laptop to a technician to get it soldered again.

Keep me posted on the development of the case. Cheers.
