Dell XPS 710

My customer has a Dell XPS 710. It is running Windows Vista. He was experiencing startup/power issues. He would have to try several times to power the unit up. If he let it sit for a while it would eventually power on. Now it gets an amber powerlight for 1 to 2 seconds, the power supply fan turns on and then off. I tried another power supply (a DR552 - 750W) and get the same issues. What else could it be? I assume it could be the motherboard but i don't understand how the motherboard would have the intermittant issues that the customer has  originally been dealing with.

Sounds like a capacitor problem or an issue with the voltage regulator. Either way the motherboard needs replaced.

Yep.  Motherboard... I have this with some HP notebooks that have defective on-board graphics GPU (dv6500).   I can only assume that the the GPU is having intermittent power issues that make the motherboard short and power off.  

Just to be sure, I have seen it be a defective battery also, but rare.   Plug the power into the laptop without a battery and see if the issue is recurring.

Thanks.

Replaced 8 2200uf capacitors and 6 850uf capacitors on the motherboard. Unit is running like new.
