No Thermal Zone with a Sager NP3760 (Clevo M375E/M375W) and kernel 2.6.9 (DSDT available)

(Please CC me, I am not a member of the list)

Thermal zoning is not detected by the stock ACPI code in 2.6.9 on my Sager NP3760 laptop (a rebranded Clevo M375E or M375W, IIRC). iasl 20040918 spits out these errors when attempting to compile the decompiled DSDT:

Do any of these errors have anything to do with it?

2.6.7, 2.6.8.1 and 2.6.9 have all failed to detect the thermal zone on this machine; should I investigate a BIOS update?

The DSDT is available here:

Thanks in advance,

Hi,

I have an equal-ish problem with my Acer Aspire 1703SM. Before using the DSDT for the Aspire 1703SC I had thermal support but no battery support.

After I that I have battery support and all but the kernel tells me happely that my temperature is critical.... as in.. 255 degrees Celcius.. somehow I dont believe him ;-)

Any idea what might cause this error?

Mr. Ale,

Other than the obvious? ;-)

If I knew what machines had similar BIOS and hardware arches, I would willingly try their DSDTs; but I don't want to turn my machine into a doorstop...

I'd rather modify the existing DSDT and try to make things work that way.

Good morning :)

Yeah, when I read back my own mail this morning the only thing I could do was do a big frowning and asked myself what I wanted to achieve with this mail :P

I am trying to fix the original DSTD by hand now (and failing
misserably I might add). I might give someone SSH access to my
laptop so he can play around with my machine. Acer wasnt very helpfull on this matter :/

I hope your problem is fixed or will be fixed soon. Good luck :)

Oh.. and it's just Patrick, no Mr Ale.. Mr Ale makes me feel old and wise.... I am 25 and far from wise ;-)

Take care

Patrick
