Having problems with your PC Laptops ?

Laptop display distortions

\015 Hi,I'm not sure the motherboard is bad. Here is what happens, the laptop work fine and after several hours the display gets distorted with several vertical sections rolling up and down. I thinks is a heat problem, because the fan is running too slow. When you press the power button, the fan goes full speed and then is slows down. You can not feel any air passing thought the bottom of the laptop. With this information do you know if the motherboard has to be replaced or is there some way to speed up the fan. I checked the voltage at the fan (red/black wires)and when it start there is 4.0 volts and then it goes close to zero volts.Any help I would appreciate.Thanks.Manny\015

Answers :

I can not give you a complete answer to this, but i will be more than happy to provide you a couple of opportunities. for one, depending on your model there have been some new updates on manufacturers websites for issues described such as yours. there have been known issues arising from the VGA chips on many major manufacturers. they are aware of it but not always quick to let you know. try going to the corresponding website and check the bios software and see if you need to first flash your bios. this is a first with anything. most of them will ask what version you have.

i have corrected many issues with just this fix. now depending on your model this may or may not resolve your issue. but i can almost say that you do have a motherboard issue. hence the bios update. i have seen this very often and 9 out of 10 times they replace the motherboard. but keep in mind they often do that with the same type of board. so you basically buy yourself some time. the symptoms your talking about i see very often in the HP dv series laptops.

good luck!
