Already enough But interesting that not every device has this problem.

Nice to know. Fujitsu told me that they can not reproduce this error and they seemed not to be aware of this malfunction. This seems to be the second buggy funtion in the bios. The first was is one: Source I was using 1.19 but this problem never get solved (even after a mainboard replacement). And it does not occur only in Win 7, also in Win 8.1

I got my money back from Fujitsu so I can't test this. Have you tested it for a long time or just a few days?

Same problem, same device. This is not the only issue: http://answers.microsoft.com/en-us/windows/forum/windows8_1-hardware/acpi-driver-causes-high-cpu-load/069d697e-ad4c-430d-ba3b-718c08981ec7 Just wondering why just a few are reporting this issue. I always use newest drivers and bios version.
