Having problems with your PC Laptops ?

Fan wiring ive been told by another tech to wire the cpu fan in a laptop directly to the power surpply as it does not recieve power in its current position and i know that it still works, i need to know where i should rewire it to? need detailed answear

Answers :

That is absolutely wrong. You cannot wire the CPU fan to the power supply because you will most likely burn the fan out. The power supply (ac adapter) is most likely feeding 19 volts to the motherboard, which is broken down into lower voltages to run various components. The fan may only be a 1.5 or 3 volt component. Fan speed is controlled by the voltage, so it would spin up much higher than it is designed for.
\015\012And even if it did work, the fan would not step down or idle at any time so it would fatigue and burn out from constantly spinning at a high speed.
\015\012CPU fan failure would almost certainly lead to a cooked cpu, damaged motherboard or both. You should have the machine serviced to repair the fan circuit unless you are willing to risk the loss of the whole machine. It is too critical a component.

Lockup My computer works great except, it frequently freezes and will not take any input from the mouse or keyboard. It generally does it while you aren't using any input. Loading of a page or navigation on line. There is no pattern to it and it's even froze a couple times on the screen saver. I can seldom go for more than a couple hours without this occurring, sometimes only a couple minutes. The only cure is a reboot. I'm pretty sure it's a hardware problem. I've added a second hard drive, a f
