My laptop will no longer start up. It will shut down itself after a few seconds during POST (and it is not related to the operating system (Linux, Fedora 14) in any way since the problem occurs also when the hard disk is removed).
The laptop is fairly new (January 2011), based on Clevo B7130. There was no such problems in the beginning. Then one day it would not start up with the symptoms like I have recorded later. After some attempts I gave up. It started up fine later (probably the same day, but I do not remember for sure), so I assumed that it might have been a single occurrence problem.
However, the problem occurred again after this, more and more frequently as time went on. While in the beginning of experiencing the problem I usually could get it started after several attempts, now it never will (unless if I wait a long time (days)).
I have also experienced (three times I think) during normal usage that power have just gone.
Anyone that have any ideas of what the problem might be? My suspicion is that it is related to the CPU fan, because when it fails to start up the fan is running at full speed making much noise. The few times it starts ok, the fan is not kicking in at full speed. I tried to detach it for testing, but then the laptop refused to start.
However there might also not be something wrong with the actual fan (AB7505HX-GE3), could it be a bad temperature sensor, a BIOS/ACPI bug or a poor contact or shortcut on the PCB?
