Dear,

When i start my laptop it just starts up but after exact 30 seconds it makes a "click" and just falls out. I've made some tests:
1) changed my RAM memory
-> nothing changed
2) checked my harddrive for errors
-> nothing changed
3) started my laptop without harddrive
-> still falls out after 30 seconds
4) took out my CD-reader
-> nothing changed
5) my cooler is working fine, my laptop doesn't get overheated
6) the battery makes no difference if he's in my laptop or not

I've tried to make a kind of log to see if it's always exact 30 seconds here's the result:

NORMAL BOOT
-----------------------
1 31.17s
2 31.45s
3 30.78s
4 30.34s
5 31.23s

F2 SETUP
-----------------------
1 31.07s
2 31.03s

F2 SETUP AND EXIT
-----------------------
1 30.52s
2 31.13s

F12
-----------------------
1 31.28s
2 30.97s

It doesn't mater how I start my laptop or what I do, after 30 seconds it just shuts down..
Can someone please help me? I can't find any solution on the web..

This really points toward a thermal issue. How do you know your laptop is cooling? Sometimes dust and debris gets between your heat sink and fan and just because your fan is spinning doesn't mean it is pulling any air through it.

If that is how long it takes for your laptop to overheat, yes. You might take a can of compressed air and blow it in the heat sink vents of your lapop for good measure.

Something else you might try is removing your laptop battery. I have seen defective batteries cause strange problems.

Otherwise we can rule out it being a hard drive or windows problem since it does the same thing when entering and staying in the bios.
