acer TM 233 s3 problem: screen does not resume, no autohalt

acer TM 233 s3 problem: screen does not resume, no autohalt

[Keld Jørn Simonsen]

Hi

I have an Acer Travelmate 233 running MDK 10.0 RC1, kernel 2.6.2.
When I put it in "mem" save and resume it, the screen will not come
up, but other things work, such as an ssh from another machine.
Also the cpu does not seem to go into autohalt, consuming about 38 W
instead of the normal 18 W (ideling)?

Can I turn the screen on with some shell command?
(from my ssh session)

Why does the cpu not idle halt?

Is there a way to just put the CPU off (seletcet S3 or you could call it
S2)? I would like to have the ram, screen and keyboard and mouse running, and
the CPU shut down (no power)  
This could happen after ideling for 1 second. How could that be done,
and any comments on it?

I think I in this way could get down to maybe 11 W.

Or, as it only takes about 0,8 W in S3 mode, it could be:

RAM      0,8 W
Screen   3,6 W
Mouse      ? W
-----------------
Total    5,0 W

Leaving me 12 hours on my 60000 mWh battery 

best regards
keld

Hi, I have the same problem with the screen not resuming on my Acer 3000
Ferrari. I have had that problem from the first kernel 2.6.0-test6 to my
current kernel 2.6.3. Otherwise ACPI works fine. But I get alot of group
battery / action battery events and some group processor / processor
events that I don't know how to use. What are they for?
