Does anyone have this laptop and have any experience with getting power management to work better with it?
As of now, I've got everything else working (sound, GPU, cpufreq, wireless, bluetooth, etc.) perfectly but a bunch of nagging issues are causing me a lot of headache.
The most annoying issue is the battery. For whatever reason ACPI never knows the discharge or charge rate of the battery, so I can never get an estimate of time remaining.
At 100%, it looks like this.
Battery 0: Full, 100%
Battery 0: design capacity 440 mAh, last full capacity 440 mAh = 100%
Discharging, this happens.

[mm23@pegasus ~]$ acpi -b
Battery 0: Discharging, 98%, discharging at zero rate - will never fully discharge.

[mm23@pegasus ~]$ acpi -b
Battery 0: Discharging, 97%, discharging at zero rate - will never fully discharge.

[mm23@pegasus ~]$ acpi -b
Battery 0: Discharging, 96%, discharging at zero rate - will never fully discharge.
Charging is the same thing in the opposite order.
The problem lies herein:
[mm23@pegasus ~]$ cat /proc/acpi/battery/BAT0/state
present: yes
capacity state: ok
charging state: discharging
present rate: 0 mW <--- HERE
remaining capacity: 4657 mWh
present voltage: 10800 mV
I'm pretty sure it's a DSDT issue and I have absolutely no experience with those. Google's got nothin'.
The other issue is suspending. The suspend goes perfectly, but upon trying to resume it seems it can't read the hard drive anymore so I get random ext3-fs errors. This issue is completely identical, under the same exact circumstances, as what is reported in this thread: http://bbs.archlinux.org/viewtopic.php?id=46758

I have this same issue (the battery discharge rate not detected - so no remaining time estimate) with a fresh install of arch on my laptop now (lenovo 3000 n100), which is weird because my battery worked perfectly fine in a previous installation of arch.

Let me bump again...
The problem still exists on my Lenovo 3000 N200. Any ideas?
BTW: We discussed the same matter in this thread but the solution (kernel downgrade) was quite unsatisfying...

Hi, I have the same problem with a Compaq Presario V3700, I fixed my DSDT and it had no affect. mm23 if you could send me your DSDT I could try and fix it. You can extract it with:
sudo cat /sys/firmware/acpi/tables/DSDT > dsdt.dat
