I have an Acer Travelmate 4150. A couple of days ago i was working on it and it just powered off. No error messages or warning. It came back on no problem, and no events in the event log. It had been doing it all weekend.
Using the Acer Epower Management tool, i set the CPU speed to medium and it doesnt crash, but when its on maximum performance, it crashes around every half hour. Fan is sorking correctly and it doesnt seem to be overheating. It is out of warranty so cant return it to Acer!
Any help of comments would be appreciated.
