I'm having a similar issue as stated above: After a couple of minutes (from ½ to about 3 minutes) the computer freezes.
Tested, with the same results:
1. Standing in BIOS (v42)
2. Running Ubuntu Linux in terminal mode with less than 1% CPU usage
3. Running Ubuntu Linux in KDE, Gnome, Unity and Xfce
4. Running USB-bootable drive without HDD
5. Running Memory tests (on Ubuntu Installation disc)
6. All above both with LAN, USB-WLAN and no Network device connected
7. Running Ubuntu (Unity) with no screen connected, after a couple of minutes connecting a screen
8. All different possible "run CPU fan all time" to "run CPU fan as little as possible" settings in BIOS
BIOS is really showing some interesting CPU temperatures - jumping between 75 and 100 seemingly randomly.
Is there some type of suggestion for solving this - which is not "attach a thermal pad between the SSD and the chassi" I would be glad to try it out.
