Typically, my ASUS laptop has gone weird just after the warranty has expired...

My theory is that the MOBO is not good.

After cold start, it runs for about 5 mins then emits a very very high pitched squeal. This wavers depending on CPU load. Google says this may be whistling capacitors on the MOBO, or a switched mode PSU on the MOBO supplying the CPU (it comes from an area near the CPU, and on;y seems to happen when running on AC).

After another few minutes, it enters hibernation automatically. After rebooting it only runs a short time before hibernation.

I thought maybe the fan was not running correctly, and was right, it doesn;t seem to run, so I connected it to an external 5v PSU so it was running full speed continuously. The problem still occurs, so I guess I can rule out overheating, with thermal protection causing the hibernation.


Has anyone had a similar experience? Shame, I really liked the ASUS model......

Have you cleaned the laptop out recently? Try blowing some air (canned air works great) throughout the laptop to get the dust and junk out of it.

It could be the motherboard going bad too. My moms computer at work kept randomly shutting off because the capacitors on the motherboard were leaking electrolytes. You could always open the case up and check these out.
