Temperatures and battery?

[yogev_ezra]

The CPU heat sink (thermal pad) is connected to the top cover (where the words Fit-PC 2 are printed). So the top cover is much warmer than the bottom one. Try to hold it from the bottom and it will be cooler.

Well, it's not like I need to hold it while using it

Yogev, Ender,

That's exactly the information I was looking for. Thanks! For anyone else reading, the site said the case gets to 50C under load, or ~120F.

If you're curious, I want to put it in a place where my kids might touch it. These temperatures are well within what I'd consider safe, though I might want to keep it out of the crib

Both Windows and Linux detect three battery slots, and one is connected to a virtual battery, charging at 84%. I wonder if it is an image of the input voltage, because the fit-pc 2 accepts different input voltage...
Could Compulab give more information about this virtual battery?

Thanks

I looked at the temperature and battery under Linux (SuSE 11.1):
---
acpi -t
Battery 1: charging, 84%, rate information unavailable.
Thermal 1: ok, 0.0 degrees C
Thermal 2: ok, 0.0 degrees C

The ACPI of the fit-pc2 seems to be buggy here and report a
non existing battery (details below). The temperature reading
is not functional under SuSE - Windows seems to work according
to earlier posts.

Are there fixes planned? Workarounds available?

Here are more details from the ACPI:
---
# cat /proc/acpi/thermal_zone/TZ00/temperature
temperature: 0 C
---
# cat /proc/acpi/thermal_zone/TZ01/temperature
temperature: 0 C
---
# cat /proc/acpi/battery/BAT0/info
present: yes
design capacity: 10000 mWh
last full capacity: 10000 mWh
battery technology: rechargeable
design voltage: unknown
design capacity warning: 1000 mWh
design capacity low: 400 mWh
capacity granularity 1: 100 mWh
capacity granularity 2: 100 mWh
model number: CRB Battery 0
serial number: Battery 0
battery type: Fake
OEM info: -Virtual Battery 0-

# cat /proc/acpi/battery/BAT1/info
present: no

# cat /proc/acpi/battery/BAT2/info
present: no

(The ACPI reports 3 batteries, but only one is reported
as present - but the design capacity is huge)

These are indeed ACPI issues and will be resolved in next BIOS release.

[lazytt]

Has this next bios been released yet? Is there an eta?

just updated to the latest BIOS,

battery issues fixed, thermal issues not quite fixed

$ cat /proc/acpi/battery/BAT0/info
present: no

$ cat /proc/acpi/thermal_zone/TZ00/*
<setting not supported>
<polling disabled>
state: ok
temperature: 0 C
critical (S5): 127 C

$ cat /proc/acpi/thermal_zone/TZ01/*
0 - Active; 1 - Passive
<polling disabled>
state: ok
temperature: 0 C
critical (S5): 95 C
passive: 95 C: tc1=0 tc2=10 tsp=2 devices=CPU0 CPU1

is this expected?

CPU works even at 105C. 71C is just fine.
There is not really a battery. Battery driver and applet can be disabled.

Well, that is max tolerance, but for longlivety i would not recommend going above 55 degeree celcius for a prolonged period of time... So, that old heatsinktrick with some thermal paste is quite handy afterall. What is the best place to mount the heatsink (Top or bottom)?

Is it also possible to use tools like RightMark CPU Clock to:
-Use EIST to scale the CPU speed and voltage manually?
-Undervolt the CPU?

Setting the powermanagement profile under windows xp to Maximum Powersaving also enables the throtteling of the CPU

Is it also still possible when overclocking to change the voltage and use the EIST (speedstep)?
