Laptop Display goes black when I plug in power cord
Posted on 2008-10-13
This laptop will usually start up fine on battery power (but not always). But when I plug in the power cord I can barely see the display...almost completely black. It would seem that the back light is going out, but it seems to have something to do with the power cord. The cord tests ok with a meter. Also, it does the same thing on battery power alone...just not as often. It also does it if I run it with the power cord only. However, It does seem to do better if the battery is fully charged and no power cord. Any suggestions? Could it be a bios problem? Also, how hard is it to change a backlight (for future reference) and where can you buy them? I have a lot of experience with hardware, but not with laptops. Thanks for any help!
