Does anyone know what kind of fan script will work on the AOD 150 with Intel Atom N280 Thank you.
This patch appears to now be in the development kernels in the acpi-wmi: http://patchwork.kernel.org/patch/14619/ "Acerhdf is a driver for Acer Aspire One netbooks. It allows to access the temperature sensor and to control the fan. "
Thanks for the reply. But I can't see where it says the module also supports the new AOD models with BIOS v. 1.02 - 1.05. Does the acerhdf module work with these BIOS versions too? Has anyone tried it, or is there any other solution?
It's not in any development kernels or acer-wmi or anything, he submitted the patch to the mailing list but it doesnt work with 2.6.30 and missed the merge window. Doesn't help this though because it doesn't work with the EC on the newer systems. Grab the acer_ec.pl script and run this command watch -d sudo perl acer_ec.pl regs and post what row 50 column 05 says when the fan comes on or goes off. Row 50 column 08 should be your current temprature. Hopefully row 50 column 05 is your fan control like most other acers and if so I can edit acerfand's script to work with it if you can give me the numbers.
Thank you for your help. It doesn't look good though. Here's the result after running that command: Code: 00 01 02 03 04 05 06 07 | 08 09 0A 0B 0C 0D 0E 0F __ __ __ __ __ __ __ __ | __ __ __ __ __ __ __ __ 00 | 2 0 0 0 0 0 0 0 | 0 0 0 0 0 0 0 0 10 | 0 0 0 0 0 0 0 0 | 0 0 0 0 0 0 0 0 20 | 0 0 0 0 0 0 0 0 | 0 0 0 0 0 0 0 0 30 | 0 0 0 0 0 0 0 0 | 0 0 0 0 0 0 0 0 40 | 0 0 0 0 0 0 0 0 | 0 0 0 0 0 0 0 0 50 | 0 0 0 0 0 0 0 0 | 0 0 0 0 0 0 0 0 60 | 0 0 0 0 0 0 0 0 | 0 0 0 0 0 0 0 0 70 | 0 0 0 0 0 0 0 0 | 0 0 0 0 0 0 0 0 80 | 0 0 0 0 0 0 0 0 |
Looks like it's WMI controlled like most other acer laptops then going by the BIOS changelog, have you tried the acer-wmi kernel module?
No, I have no idea what it is, I'm afraid. Just had this AOD150 for a few days and would like to silence the fan just once in a while.
no chance, that thing is completely different, and I didn't realize acer-wmi doesn't handle thermal stuff so scratch that if you can install acpidump, switch to root with sudo -i or something, and do acpidump >> acpidump.txt && dmesg >> dmesg.txt && tar cfvz atom.tar.gz *.txt and send that atom.tar.gz I can take a look and see if I can spot anything though.
Sarvatt, sorry about the delay. Easter holidays. I was going to send you the files, but they were too large to post. In the meantime I also managed to screw up my Ubuntu 9.04 beta installation and have now reinstalled XP instead. The fan is very silent with XP, much less spinning than with Ubuntu so I just might stick to XP for the time being since I don't have time right now for further experimentation. Thanks though for your time, it's much appreciated.
No worries, if thats the case then it's probably an ACPI problem, windows XP doesnt support HPET's or pcie aspm and alot of power savings options which might be screwing up in linux/vista. I'll take a look at it when ya send it if you still can.
