Thanks, unfortunately it is an old computer (from 2004), the newest |
97 |
BIOS, which is several years old, breaks suspend (it does not resume |
98 |
from suspend, not even Windows XP works...), so I'm using the |
99 |
penultimate BIOS. It's an Acer Ferrari 3400, back in the time when I |
100 |
bought it, the internet was full of people who have to edit their DSDT |
101 |
on Acer laptops in order to fix it, many people had no battery support |
102 |
at all. |
103 |
|
104 |
I know I used some "magic" kernel parameters at some point, I'm not |
105 |
sure if it was ACPI related, though. I will look into them to see if |
106 |
there's anything new in the past 5 years of kernel development that |
107 |
might help me. :) |
