Hi, I am using an ibm t43p and have realised that the fans are spinning *all* the time. When I was using the same laptop with a debian flavour I scarcely could hear them spinning.
In dmesg I see cpu0: unknown Enhanced SpeedStep CPU, msr 0x0612112b0600112b cpu0: Enhanced SpeedStep 2267 MHz (1388 mV): speeds: 2267, 800 MHz This "unknwon" must be the problem... ?? in any case, I have tried playing around with sysctl this way tuffstein| sysctl -a hw.cpuspeed hw.cpuspeed=2262 tuffstein| sudo sysctl -w hw.setperf=50 hw.setperf: 100 -> 50 tuffstein| sysctl -a hw.cpuspeed hw.cpuspeed=2267 tuffstein| sudo sysctl -w hw.setperf=0 hw.setperf: 50 -> 0 tuffstein| sysctl -a hw.cpuspeed hw.cpuspeed=800 But this doesn't help at all... the fans spin still all the time... Even after suspending the laptop (zzz) and "waking it up" two hours later, so that the laptop is very cold, after some 20 sec the fan starts spinning again... and the laptop is cool, some 15 degrees C How do I reduce, if not totally eliminate this noise? Before you ask, yes, I have googled around but I must be very bad at it because I found nothing but this http://www.cse.unsw.edu.au/~dons/x31.html and he's doing the same than I am If you're curious, here you are my dmesg It says "using only highest and lowest power states"... maybe that's the reason ---------------------------------------------- OpenBSD 4.0 (GENERIC) #1107: Sat Sep 16 19:15:58 MDT 2006 [EMAIL PROTECTED]:/usr/src/sys/arch/i386/compile/GENERIC cpu0: Intel(R) Pentium(R) M processor 2.26GHz ("GenuineIntel" 686-class) 2.27 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,TM,SBF,EST,TM2 cpu0: unknown Enhanced SpeedStep CPU, msr 0x0612112b0600112b cpu0: using only highest and lowest power states cpu0: Enhanced SpeedStep 2267 MHz (1388 mV): speeds: 2267, 800 MHz real mem = 2145873920 (2095580K) avail mem = 1949347840 (1903660K) using 4256 buffers containing 107397120 bytes (104880K) of memory mainbus0 (root) bios0 at mainbus0: AT/286+(e5) BIOS, date 05/18/06, BIOS32 rev. 0 @ 0xfd760, SMBIOS rev. 2.33 @ 0xe0010 (64 entries) bios0: IBM 2668Q1G apm0 at bios0: Power Management spec V1.2 apm0: battery life expectancy 98% apm0: AC on, battery charge high apm0: flags 30102 dobusy 0 doidle 1 pcibios0 at bios0: rev 2.1 @ 0xfd6f0/0x910 pcibios0: PCI IRQ Routing Table rev 1.0 @ 0xfdeb0/256 (14 entries) pcibios0: PCI Interrupt Router at 000:31:0 ("Intel 82371FB ISA" rev 0x00) pcibios0: PCI bus #12 is the last bus bios0: ROM list: 0xc0000/0x10000 0xd0000/0x1600 0xd1800/0x1000 0xdc000/0x4000!
