Installation: Installing Ubuntu
proceeded without any problems, most of the components work immediately after the first run of the system.
was used to install my flash drive on which the recorded image of Ubuntu 10.10 with a boot disk Assistant, which can be found in Ubuntu;].

cooperation with the system hardware:
Great. It is only, as in the D610 model, install the IrDA compatible (podczeriweń)

- Installation IR
Just install two packages: irda-utils and ircp-tray by typing:

sudo apt-get install irda-utils-tray ircp

Then type the following commands and reboot: sudo modprobe
irda-usb
irattach irda0-s

I do not know if it works, because they do not already have an infrared device;]

problems and their solution:
- Irritating sound when on battery
is a high frequency sound (high-pitch noise) heard it while working on battery power. The cause of this sound is more responsible for the ACPI power and thermal management. More technical details can be found on the pages describing the Intel C-State Architecture.
To get rid of this problem
edit / etc / default / grub the rights of root, and change the value in a line containing:

GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash"
the
GRUB_CMDLINE_LINUX_DEFAULT = "quiet pci = bios idle = halt acpi_sleep = s3_bios splash"

Undervolting:
In brief: the temperature and reduces power consumption by lowering the CPU voltage.

While the processor T2300 (2x1, 66Ghz) on my copy of the stable value of the multiplier for the two cores are
8:4 6:1 10:4 But probably with a value of 10 and 8 I can go even lower. Please note that not every processor, this model can get these values.
