I recently bought Acer timeline 3830tg for my studies and installed ubuntu 11.10 and currently using gnome-shell. I also have changed by graphics mode from hybrid to integrated mode to increase battery backup. With all this steps I have encountered some more problems. Could you please help to fix these issues:

  1. Fan gives too much loud noise (does not even stop for single second this didn't happen in Windows)
  2. Battery backup in Windows was 7 hours plus but it hardly shows 3 hours in Ubuntu
  3. I am not able to control screen brightness from keys provided
  4. I had used gparted for partition. in one partition i have not kept single file/folder but then also it shows 34gb used

I would be very thankful if someone could help me to solve this problems as soon as possible, especially the battery backup issues.

I am also using acer aspire 5742 laptop.

I made changes in GRUB_CMDLINE_LINUX_DEFAULT and GRUB_CMDLINE_LINUX to /etc/default/grub
- GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force"
- GRUB_CMDLINE_LINUX="acpi_osi=Linux"
and after adding these lines update grub from terminal by executing

sudo update-grub

By default the above lines will be different please check it and modify it.

If you are using sandbridge processor then after making change refer

Laptop minimal power consumption tweaks

And then check hows the performance and the operation of fn key
