Satish the only thing I might add to this is that in my experience, when
you do the 'shorting' of the cl1 cl2 pins the machine must have power
available, it is no good doing it with the battery removed it wont work,
in fact the machine has to be switched on. (see my post dated
"2012/11/21 18:38" on this site:
http://www.linlap.com/fujitsu_lifebook_ah532 ). I tried it with power
removed and absolutely nothing happens. Bear in mind that what I did
there is potentially dangerous both to you and the machine.  Another
thing to try (a lot safer! ) is to remove the cmos battery (if you can
find it, I dont know where it is) this has reportedly worked on other
machines, but I can't gurantee it will work on the Fujutsu.

In my case I only finally solved this problem when I removed Uefi from
the system completely (deleted the Efi System partition). Having done
that I had to do my motherboard shorting/bios flashing routine one more
time then reinstall everything in 'legacy' mode, after which the problem
has gone away for good.

This is a problem with Fujitsu's bios/uefi firmware in my opinion, it is
very similar, if not identical to the problem affecting Samsung machines
(which seem to have been more widely publicised than this).

I don't know if Matthew Garret's kernel patch will solve this problem
for the Fujitsu, but I suspect it will.

I don't know how widely this patch has been applied just yet, obviously
having totally removed Uefi from my machine, and having no desire to
ever put it back, I can't test it.
