    Default Why is my laptop's screen flashing like this?

    I have had my laptop for less than a year, and about two weeks ago I noticed that the screen flashes erratically. I am not sure if "flash" is the correct word to use, but it is extremely noticeable. The only thing I installed the day before it started acting up were Windows Vista Service Pack 2 and a Definition Update for Windows Defender. And a few days before that I updated mozilla firefox 3.5. I also noticed that if I plug in the AC adapter it stops flashing, but as soon as I pull it out, it starts flashing all over again.

    Here is what I am talking about:

    Could be a multitude of things. From motherboard, LCD inverter cable, LCD itself, GPU to a bad video driver. Take ZaZ's advice, call support soon (and hopefully you aren't out of warranty).

    Try upgrade to the latest graphics drivers.. I'll admit I haven't seen the video because I'm on dial-up at the moment..

    lol, no no.. I'm actually on cable, but I've been shaped to 8KB/s for downloading over 60GB this month so it's essentially dial-up speed for me right now.
