Like I was thinking, exact same chip, just with a different BIOS. The only difference is the frequency. Even the PCI-ID is the same!

Having said that, they might be better overclockers.

I'm on exactly the same versions, but I can't control the brightness via fn + arrow keys. The automatic switching when on battery works flawless... the P-Button works as usual (including the blue light).

I've read the initial post in the german forum regarding fan control, and the last couple of pages... we'd have to use either ACFanControl or RW-Everything to identify the registers and to probe which ones are for fan control.

At least it will be a lot of trial and error. ACFanControl can diff two EC-states out of the box, while with RW-Everything external tools must be used.

Here's the method to collect all necessary data:

• open your preferred monitoring tool
• wait till the fans shut down and the temps are stable
• take a screenshot from your sensor state
• save the ec state (ACFanControl: read EC->EC1; RW-E.: Access->Embedded Controller & choose preferred save format (ASCII/BIN))
• stress your system to high + stable temps
• take a screenshot from your sensor state
• save the ec state (ACFanControl: read EC->EC2; RW-E.: Access->Embedded Controller & save)

Now we've got everything we need to identify the possible addresses:

• diff the two ec states (ACFanControl: disp. EC2-EC1; RW-E.: use your preferred diff tool)
• identify the known addresses by comparing the values with the ones from the monitoring tool (mind the hex to decimal conversion)

Every value left may be for the fan control. Try to get low temps and set the values read from the high rpm state one by one.

Perhaps you'll have to run the whole procedure again and again to identify more known values.

If there's no success with above method: set values from 0 to 255 for each unknown register

Woah!!! I was looking all day for a possible GPU fan control, as mine only works well with 1.13, but with that one it produces strong bursts about once every 5 minutes. With 1.17 and 1.19 it can go into infinite sine-wave loops, and stucks.

Did anyone has any progress in making the ini files for 3820TG? I hope our machines have the same controllers.

OK, this is as far as I came with the registers:

131 - brightness level 0-9
135 - brightness level 0-255

Reading works, but writing doesn't. It actually changes the data, but nothing is happening.

There seem to be many random fields, which change even if I don't do anything. First we should write a list about the "useless" fields, then we can start comparing the interesting values.

anyone have a link for the larger battery? Are the batteries the same thing with the hd graphics and ati models? Shipping to us too?

Id like to get a larger battery when I get it, any stats or comparison between the two?

I found this 200 pages back

im thinking of getting this laptop tomorrow. will it play 1080p movies hooked up to a tv, even though the laptop cant fit 1080p on its screen?

absolutely.

Acer has the 1.3 hdmi supporting resolutions of up to 2560×1600 which means any external monitor able to display up to its maximum will work. The display on the laptop resolution hasn't anything to do with the hdmi output.

Check a thread like this though as there are many discrepancies. DVI and Display port can use the external monitors/TV native resolution while hooked up to the laptop though. Check here for reference. VGA can only support resolutions of up to 640x480 in 16 bit color so that wont use your TV's native resolution im pretty sure, some one correct me if Im wrong since Its not my money im using to figure out what works with what but any who lol!

PS;anyone know where some one in US can buy a 9 cell 3820TG battery from?

wait wut? VGA can only support up to 640x480?
I don't think that is correct.....

VGA can support resolutions as high as HDMI or DVI. It really depends on the monitor or TV.

did tests with OCing the 5650 with my i3 370m and got these results playing Starcraft II

Default clocks
Medium - 62 fps average
High - 42 fps average

oc'd 650/950

High 70 fps early game (averaged 45-50 fps during big battles ~140 units on screen)
Ultra 30fps early game

yes i know I should have used the same settings but it runs on high amazing after being oc'd
