[tlinux-users 00652] Toshiba Portege M400 hangs, cause HDD Protection or accelerometer

I am new to this newsgroup. A few weeks ago I bought a Toshiba Portege
M400 laptop/tablet. It boots very good under Linux Mint 12 and most
But I have a big problem.
When the computer is moved slightly or the screen is rotated it
totally locks up / hangs and the fan goes into turbo mode. I have to
hold the power button for 10 seconds to hard power off.
On internet I found this problem a lot and the solution had to do with
HDD Protection and/or the accelerometer. When moving the laptop it
puts the harddisk in some locking mode to protect the disk. This
mechanism gets more sensitive when aging?
Under XP you can turn that off, so it seems (doesn't work under XP SP3?).
For a tablet this problem makes it unusable.
Please can anyone tell me how to repair this?
Would it work well with an original Toshiba harddisk?
Can I fully disable this protection or even this accelerometer under
Linux or in firmware or hardware?
Or is my analysis totally wrong?
I really hope there is a solution to this problem, even if it needs
soldering. Exchanging the motherboard is to expensive so isn't the
answer I hope for.
Thanks in advance.
