this is probably not related to arch per se, but I didn't know where else to ask.
This is an aod250-1613, the one that comes with Android (which itself has problems with acpi events of this laptop, who knows how and why).
it seems that arch (nor ubuntu, windows can sporadically) cannot read cpu's temperature correctly. Note the temperature, 26.8C, below. A few minutes ago, because the laptop was on my lap and couldn't get air in, it turned its fan to its fullest. Not understanding why, I touched the bottom and ouch, extremely hot! It seems that the highest value it can report is 27C!
$ acpi -V
Battery 0: Charging, 85%, 01:04:02 until charged
Battery 0: design capacity 5800 mAh, last full capacity 5500 mAh = 94%
Adapter 0: on-line
Thermal 0: ok, 26.8 degrees C
Thermal 0: trip point 0 switches to mode critical at temperature 100.0 degrees C
Thermal 0: trip point 1 switches to mode passive at temperature 85.0 degrees C
Cooling 0: LCD 0 of 9
Cooling 1: Fan 1 of 1
Cooling 2: Processor 0 of 10
Cooling 3: Processor 0 of 10
$ cat /sys/class/hwmon/hwmon0/temp1_input
26800
cat /sys/class/thermal/thermal_zone0/temp
26800
I updated the bios to its latest version (1.22 for d250).
What do you think? Is there anything I can do?
PS. the battery reportedly can only charge to 94% of its design capacity. I do not know why, but hopefully I'll try to replace it. I used acpi -V in case battery is relevant to this issue.
Edit:
The modules acer_wmi and acerhdf cannot be loaded, they give the "ERROR No such device" error...
Edit 2:
I sent an email to the kernel mailing list (acpi). But I have no experience with reporting problems to the kernel folk, so I'll probably not going to get input. I just wanted to have this post linked to that email for reference purposes: http://www.spinics.net/lists/linux-acpi/msg26078.html & http://eeek.borgchat.net/lists/lm-sensors/msg27503.html

Yes i can confirm that here on my D250, it always show 27 degrees C.

ironically enough, that makes me feel better Any chance you could also tell me what it says about your battery status? that's another of my problems...

Sure, here it is:
present: yes
capacity state: ok
charging state: discharging
present rate: 773 mA
remaining capacity: 924 mAh
present voltage: 10876 mV

That issue can be fixed by completly discharging your battery, until your laptop shutdown by itself then recharge it to 100%, they recommend to do this like every 30 charges, so the battery can adjust correctly the remaining power.

Aie, I notice I asked for the wrong output, my bad, sorry... It was supposed to be cat /proc/acpi/battery/BAT0/info but nevermind, I don't wanna be a pain in the ass...
I read about the recalibration solution, but I don't think it would work in my case. The battery report is quite constant in how it reports 5500 (it's suspiciously rounded, not something like 4498 or so) and the last time I did a battery recalibration, I ended up losing mAh rather than gaining lol [+ the laptop is a week old]
thanks so much for your help.

edited above to add 2 kernel bug links. the later one is new bug will probably get closed. the earlier one is re:coretemp and atom processors.
