This is likely do to the fact that they just announced the microphone cable recall in the US and it has been associated with fires according to engadget or wired or one of those online tech mags.

yeah, i've also thought about that regarding fan operation and temperature..

A suggestion:

There is a module called "acerhdf" by some programmer that was initially made for the Aspire One netbook, but which has been successfully ported on the Acer 1810 to reduce fan speed under Ubuntu. The Acer 1810 is almost exactly the same as 3810 in terms of hardware - only smaller screen size and BIOS versions seem to be numbered differently.

Does anyone have the technical skills to inform us how to use this module to control fan speed on the 3810? If it works on the very similar 1810 it might not prove to be too difficult to make it work under 3810.

Does lm-sensors works? It only detects one sensor for me, and is always at 26.8ºC .
Thanks in advance.

I think you forgot to run :

sudo sensors-detect

My sensors output (32bit karmic):

user@machine:~$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:       +26.8°C  (crit = +127.0°C)                  

coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +45.0°C  (high = +100.0°C, crit = +100.0°C)  

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +44.0°C  (high = +100.0°C, crit = +100.0°C)

who knows : acpitz-virtual-0
core 1 : coretemp-isa-0000
core 2 : coretemp-isa-0001

How does it work the ubuntu 64-bit for you, on 3810t ? I want to install it because 32-bit only supports 3Gb of ram.

Hello guys, I have 3810tg with su9400
I killed ati graphic, made laptop-mode and have 10-14w
Is it normal?

Yes, my 3810T (SU9400) uses 10W when it's idle. It goes up to 20W or so when I make it sweat.

I'll try to install Arch next week, maybe it use less power...

I am using Karmic with fglrx and laptop mode. The total power consumption is slightly smaller than 10 W with wireless enabled and bluetooth disabled. When shutting down wireless and stopping some rarely needed apps I can get close to 8 W and a total battery life of 7-8 h is possible, when being moderate. I can confirm that disabling the discrete graphics and enabling the intel does not give much longer battery life, although (I think) it should...
