Having problems with your PC Laptops ?

My daughter's sony vaio vgn-cr420e turns off suddenly and randomly while in windows. battery is currently not in and no overheating is present, which i understand could cause such a problem. however, there's no dust build up in the vents and, as i mentioned, it doesn't seem to be an overheating problem. any ideas?


Answers :

It is very hard to tell when the processor is overheating. The laptop may not feel hot at all. If it is an overheating problem, there could be two different causes. One, the fan may be failing or completely failed. Two, there could be dust buildup on the heatsink which you would not be able to see by looking in the vents. The laptop would need to be disassembled to check the heatsink for the buildup. An easy way to check to see if the fan is working is to turn the computer on, let it run for just a few minutes and if the fan is not blowing hard enough for you to feel it with your hand, try holding the vents up near your face to see if you can feel any air flow.
