I installed Ubuntu in my Acer Aspire 5315 but now the cooler doesn't work anymore! I already read a lot of forums and I tried many suggested solutions but they didn't work. I already tried with the laptop-mode-tools, to enable the laptop-mode in the acpi-support file, to upgrade the kernel, and a few others.

I managed to start the cooler but it works only sometimes and it doesn't depend on the temperature. And when I restart my computer the cooler doesn't work again and then I don't have the possibility to change the settings again because all of them are already set to be "on".

The only solution that I didn't try is to flash the BIOS, because I'm not an expert and I read that this is quiet dangerous for the motherboard.

Does anybody know any other solution? I want to stay in Ubuntu but my laptop can't work longer than 15 minutes!

Thank you very much!

There is this bug, now closed because it was opened for Karmik, that is not supported anymore, and I think you should open a new one for Ubuntu 11.10:

I think you can find a temporary solution using acer_fancontrol, as suggested here:
