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!
