Acer Timeline 3810T

[mr bob]

I have a 3410 so I don't know if there is any difference to the 3810 but when I flashed 1.24, there was no saving in power and the fan was spinning permanently on battery.

I reverted to 1.17 and the laptop is nice and quiet again.

BTW, if people would like to know how to flash an older version, there is a DOS flashit option /mc, which ignores version checking.

flashit JM3100FR.117 /mc

It looks like the little script accepts one option, so this may work too:

f.bat /mc

I just installed Lucid and I just can't get Skype to work. Anyone has had any luck?

Yes, but as with karmic after installing the alsa backport stuff, I need to press my lips against the internal microphone and shout really loud. External mic works fine though.

There is 1 thing to be aware of though, you need to select the right input. The default input was my sound output being captured, I only noticed when I was listening to the news while getting my skype to work. 1st you need to start PulseAudio volume control (pavucontrol in a terminal) and go to the recording tab. It will say "No application is currently recording audio". Next you start a test call in skype and you'll see it listed, internal analog stereo is my mic and monitor of internal analog stereo is the capture of my soundcard's output.

Successful "Suspend" to RAM at last!!

Thank you all for the i8042.reset=1 fix.

New power record =D> (for me anyway).

0.567mA*11.975mV=6.789825W to bad it's not 6.789876W

Wifi on, while surfing with chromium (ok, I was reading and not loading any pages) and some stuff running in the background (conky, skype, deluge). To be fair the amps go up and down between 600mA and 800mA, 666mA now oh 742mA. Well, you get the idea. Still, I'm really happy with my new depth record.

Could you share your parameters, Miegiel?

I struggled with laptop-mode and parameters from Riskable and there but could not get my laptop under 8-9W (powertop measurement)!

And everytime I reboot, almost everything is gone

Thanks.

Concerning the microphone issues with skype, try the follwing:

1.) KMIx->Mixer->Configure Channels
2.) Add the Capture channel
3.) MArk the checkbox next to "Capture" and mute the LEFT Channel and pull the amplitude of the right channel up.
4.) Once skype is started you may have to reconfigure the colume (appears to be subject to abrupt changes). Readjust the volume of the right hand channel! It is a bit of a hassle...

BTW sound problems occur from time to time. Goto system settings->multimedia and if asked to remove the devices say yes, they are automatically added.

Kernel issue for suspend:

I have no time for (multiple) re-compilation of the kernel and I will be unavailable for quite a while. Can anyone try out the following:

- Change i8042.c and recompile kernel (see below). Restart WITHOUT the suspend fix.
Try which one works/does not work.

Changes - Version A:
static int i8042_pm_reset(struct device *dev)
{
unsigned char param[128]; // CHANGE
i8042_controller_reset();
i8042_command(param, I8042_CMD_CTL_TEST); // CHANGE

Changes - Version B:
static int i8042_pm_restore(struct device *dev)
{
int error;
unsigned char param[128]; // CHANGE

error = i8042_controller_check();
if (error)
return error;

error = i8042_controller_selftest();
if (error)
return error;

i8042_command(param, I8042_CMD_CTL_TEST); // CHANGE




Many thanks in advance.

BTW: The previous tests are needed to (maybe) induce changes in some of the future kernel versions (currently in contact with the developers).

Hmmm, it's messy, but when I go off the power grid I run 2 scripts I found somewhere in the forums. I really need figure out what they exactly do to put them in 1 script.

edit :
I should add that I use conky to

cat /proc/acpi/battery/BAT0/state | grep rate: | awk '{print $3}'

the mA drawn from my battery onto my desktop. But that's only when running on the battery, plugged in it displays the battery charging rate. I'm not sure how powertop ant cating /proc/acpi/battery/BAT0/state compare.

Oh, and I have the 3810T with the SU9400 core duo without the ATI graphics.

Anyway, here they are :

#!/bin/sh

sudo su -c "echo 5 > /proc/sys/vm/laptop_mode"
sudo su -c "echo min_power > /sys/class/scsi_host/host0/link_power_management_policy"
sudo su -c "echo min_power > /sys/class/scsi_host/host1/link_power_management_policy"
sudo su -c "echo min_power > /sys/class/scsi_host/host2/link_power_management_policy"
sudo su -c "echo min_power > /sys/class/scsi_host/host3/link_power_management_policy"
sudo su -c "echo min_power > /sys/class/scsi_host/host4/link_power_management_policy"
sudo su -c "echo min_power > /sys/class/scsi_host/host5/link_power_management_policy"
sudo su -c "echo 500 > /proc/sys/vm/dirty_writeback_centisecs"
sudo laptop_mode start
# sudo hdparm -S 4 /dev/sda
sudo iwconfig wlan0 power on

run with sudo

And yeah, need to run them again after a reboot.
