Hi Pavel, |
| 28 |
|

Hmmm, strange, I thought kernel could do it. |
| 30 |
|
| 31 |
I mean, when this laptop had Win Xp, as soon as the OS come up, the |
| 32 |
cooler stopped. |
| 33 |
|
| 34 |
When I installed Gnu/Linux it keeps the cooler on. I thought it could be |
| 35 |
somehow managed by kernel because I saw somethings about thermal_trips |
| 36 |
points which would allow me to say what to do , turn cooling active mode |
| 37 |
on and off, based on the current temp of system. |
| 38 |
|
| 39 |
The problem is only that when I turn my computer on, kernel, or maybe |
| 40 |
acpi doesn't check that and the cooler keeps on. |
| 41 |
