Acer Aspire 5315 fan issue on Ubuntu (solved)

There is a (well known) (design) problem with the Acer Aspire 5315 preventing the fan to work properly and eventually shutting down the computer to protect from overheating.

Solution comes from here and here:

  1. install mempat binary
  2. and acer_fancontrol script

into /usr/bin.

You have to find out the correct memory address for mmap().

For the 5315 wit 1.5G RAM PATCH_ADDRESS=x5F6BCEAF.

Add acer_fancontrol to /etc/rc.local and restart.

    Hello,

    How have you found out the PATCH_ADDRESS please ?

    I need the PATCH_ADDRESS for a 5535 with 3G RAM.

    Thanks in advance for your help.

    Best regards,
    Christophe

    Hello,

    I found this and it was an easy guess.
    If 1G is x3F6BCEAF and 2G is x7F6BCEAF then 1.5G is x5F6BCEAF – it just worked.

    Good luck!
