podarilo sa mi vyriesit problem so spinanim vetrakov.

popis problemu (posielane na hp podporu - bez odozvy :) ):

hi,

at first sorry for my "poor" english, but i hope that youu will get the point...

I have the nx6125 for few weeks and i cant solve the foloving problem.

i found that the default trip points in bios ar ser to: critical (S5): 95 C passive: 88 C: active[0]: 80 C: active[1]: 75 C: active[2]: 65 C: active[3]: 58 C:

at first everything seems to be ok. when the temperature reached 58C the fan turns on and the trip points was changed to

critical (S5): 95 C passive: 88 C: tp4 active[0]: 80 C: tp3 active[1]: 75 C: tp2 active[2]: 65 C: tp1 active[3]: 50 C:

then the temperature goes slowly down and when it reached 50 the fan turns off and the trip points was changed back to defaults

but when i use 100% cpu for long time the temperature reached the firs trip point again (58) fan turn on, then temperature reached second trip point (65) > fan speeds up (still everithing ok :) ) > tempearture reached third trip point (75) > fan speeds up again (still everithing ok :) ).....then i stop using cpu and the temperature slowli goes down to 60C, in this moment the second trip point was reached and fan should slow down, but it does not, it tunns off completly :(. then (in idle state) temperature slowly goes down to 50C (fan still off). the problem is that when i started to use 100% cpu again and when temperature reached 1 and 2 trip points the fa does not turn on :( it turns on only when the third trip point was reached. then i experimented a bit and i found out that the torns on only at higest trip point, ever been reached (third in this case)

so if the second trip point was not reached everything is ok, ehrn second tp is reached fans does not turn on first tp, when third tp is reached fans does not turn on first and second tp ect...

i tried to solve this by overiding the trip points by pover scheme conf, but i was not able to overide the 1 and 2 tp.

then i try to disable fan acpi module to let the bios controll the fan - does not work...also does not work to start fan manually by echo "on" > /proc/acpi/fan/C26*/state

cat /proc/acpi/fan/* cat: /proc/acpi/fan/C260: cat: /proc/acpi/fan/C261: cat: /proc/acpi/fan/C262: cat: /proc/acpi/fan/C263:

cat /proc/acpi/fan/*/state status: off status: off status: off status: off

problem bol v dsdt... upravil som to pre bios f0d : nx6125 dsdt

su tam 2 verzie: dsdt_old_modified2.dsl - iba opravene dsdt_old_modified.dsl - znizene otacky vetraku pri prvych dvoch trippointoch (55,65 C) z 50 na 32% a z 80 na 57% (mensi hluk, vyssia vydrz baterky) pre biosy f06 a f09 sa daju dsdt stiahnut na http://acpi.sourceforge.net/dsdt/view.php?manufacturer=HP&name=nx6125

je tam aj celkom pekne popisane, ako to rozbehat

jediny problem ktory pre teraz ostal, je ze ked nb bezi zo siete, nasledne sa odpoji adapter , tak procesor ide na max 1600mhz, po pripojeni spat na siet sa tiez nevie vratit na 1800mhz. jedine na co som prisiel, ze pomaha je odobrat a nasledne pridat modul k8-powersave (rmmod ... modprobe)

dufam ze to niekomu pomoze
