This notebook has a fan that runs all the time (beginning with 40=B0C). This problem occurs on Windows and Linux but I think that I have found the error in the DSDT. I am not that good in coding DSDTs therefore I hope that someone of you can help me changing the DSDT to correct that annoying bug. Here is some of the relevant code (at least I think so): Scope (\_SB) { Method (\KELV, 1, NotSerialized) { Store (Arg0, Local2) Multiply (0x0A, Local2, Local2) Add (Local2, 0x0AAC, Local2) Return (Local2) } Name (\PLCY, 0x00) Name (\BAC0, 0x78) Name (\BPSV, 0x73) Name (\BCRT, 0x64) Name (\BTMP, 0x28) Method (\UDTT, 0, NotSerialized) { Store (\_SB.PCI0.SBRG.EC.CPUT, Local0) And (Local0, 0xFF, \BTMP) } Scope (\_TZ) { ThermalZone (THRM) { Method (_TMP, 0, NotSerialized) { If (\_SB.PCI0.SBRG.EC.MYEC) { \UDTT () And (\BTMP, 0xFF, Local0) Store (\KELV (Local0), Local1) Return (Local1) } Else { And (\BTMP, 0xFF, Local0) Return (Local0) } } Look at this code: Name (\PLCY, 0x00) Name (\BAC0, 0x78) Name (\BPSV, 0x73) Name (\BCRT, 0x64) Name (\BTMP, 0x28) The fan starts at 40=B0C and 0x28 (hex) is equals to 40 (dec). Also the other code around it seems to be relevant to the fan control. But the problem is that the OS doesn't have access to the fan (no content in /pro= c/acpi/fan/) to control whether it runs or not. After changing the value of BTMP (and doing all mkinitrd stuff) the fan s= till runs. If I change the CRT (critical) the systems shows the new value= . Therefore I am sure that the new DSDT is loaded but the fan still runs = all the time. I could send the whole DSDT to the list but first I wait for someone who = thinks that he can help me. Again: this problem exists since many months = and ALL owner of the S260 have the same problem.
