Tech Support Forum - View Single Post - Asus A7T losing power

Hi.

My laptop, an Asus A7T, is nearly 2 years old, and over the last few months it's got into the habit of randomly and abruptly losing power. This mainly happens sometime into a high-resource program such as a game or when multiple lesser programs are running, such as web browsing, music and virus/spyware scan. I suspect that this is a safety measure due to overheating, but I can't track the source. I've looked inside and the fan seems reasonably clean and works fine, 5800rpm according to Everest. The temperatures listed in Everest's computer summary are:

Motherboard - 75C (165F)
Aux - 80C (180F)
GPU - 80C (180F)
HDD - 50C (120F)

where the laptop is more or less idle.

The Event Viewer displays nothing for the times of the power loss so I'm not even positive that overheating is the reason, although some of the temps seem on the high side.

This only happens when it's running off the AC, as it can't do a great deal of hardcore processing on battery, but the battery is attached and full so a faulty power supply is unlikely.

Any ideas on how to diagnose or fix the problem would be much appreciated, as it has done it about 4 times today and can't be doing itself much good.

Thanks in advance!

Martin

Edit: After setting off a Spybot scan, I'm watching the Mobo creep towards 110C while Aux and GPU are almost 100C.
