After my yesterday upgrade to Ubuntu 12.10 my laptop (Dell Vostro 3360) gets warm without the CPU fan cooling at all. At 75° C the fan seems to be off. This will result in serious problems wen running heavier processes such as video production.

Any suggestions what I can do to solve this?

Thanks :)

Install drivers if available via Additional Drivers (previously called Hardware Drivers) which is now part of software applet interface.

to turn on the fan click the power button(icon thing(top right)/suspend. turn computer back on,click switch user, then login and the fan should turn on and run normaly

this worked for me

ps. you have to do this every time u turn off your computer

sometimes you have to shutdown the computer and try again i have an acer aspire 5720z so it may not work
