Compaq laptop screen turns white

By shansueclan ·
Hi, just wondering if anyone can help me figure out why mp laptop (compaq prosignia 162) screen turns white. It just happens out of the blue and then I have to turn it back on, of course loosing everything. But it works fine if hook up a external monitor, which defeats the purpose of a laptop.

It sounds like a graphocs driver or graphics chipset issue.

You didn't mention your operating system but this link takes you to the latest drivers for your laptop, just choose the correct OS and make sure ALL drivers, BIOS, Chipset, sound etc. are all up to date.

Since an external monitor works on the laptop, we can rule out the graphics card as the source of the problem. I am not familiar with this model but, a white LCD display can be the cable that connects it to the motherboard, loose or dirty cable connections, or on some laptops there is a separate circuit board that the cable plugs into that connects to the motherboard. I would check these as the the source of your problem.

I hope thi helps you.
