This is what I have done. Some steps might seem strange but is explained by me not having an internet connection on the laptop when these tests are conducted (I will get the internet access back again)

First test:
1. A clean installation from the CD (I had massive problem with my fn-button freeze and after one hard reboot, I could not log in without a freeze, no matter what I did. I had to re-install Ubuntu 9.10 and then install Ubuntu 10.04 again before it worked (just re-installing Ubuntu 10.04 did not worked - even if I formatted the disk))
2. Boot
3. Unplugg the power cable
4. The laptop freezes
5. Hard reboot
6. Save log file as kern_mint.log

Second test:
1. Remove the pm-ubilt-powersave-policy package (sudo apt-get remove pm-utils-powersave-policy)
2. Unplugg the power cable
3. The laptop freezes
4. Hard reboot
5. Save log file as kern_nopmutils.log

6. Re-install Ubuntu 10.04 from the CD (This is to get the pm-utils-powersave-policies package back). I formatted the / partition but not the /home partition (I have three partitions on my disk /, /home and swap)

Third test:
1. Boot
2. Rename file (sudo mv /usr/lib/pm-utils/power.d/95hdparm-apm /usr/lib/pm-utils/power.d/95hdparm-apm.orig)
3. Unplugg the power cable
4. The laptop freezes
5. Hard reboot
6. Save log file kern_renamefile.log

7. Rename back the file (sudo mv /usr/lib/pm-utils/power.d/95hdparm-apm.orig /usr/lib/pm-utils/power.d/95hdparm-apm)

As you can see, nothing of the suggested things solved the problem. I hope that the logs contain the information you need. Is there any other logs that I can take to help you?

Another side note? Why is there no submit field on the Add Comment box? It took me several attempts to get the comment added...
