How-to Install Debian 6.0 (squeeze) Linux on HP 620 notebook

HP 620. It’s a great notebook for business. Hp620 is not the best about performance but it’s fast – really fast! with linux – and it’s ok with it’s easy and clean design. Its hardware is very good (almost everything is manufactured by Intel) and it’s cheap!

Above all, you can also buy it pre-installed with Linux (Suse Enterprise Desktop)!

If you want Debian just install Debian 6.0 (Squeeze) with Desktop System, Notebook and Basic System files.
After installation run these commands from shell (as root).

cd ~
mv /etc/apt/sources.list /etc/apt/sources.list.original
touch /etc/apt/sources.list
echo "deb http://ftp.it.debian.org/debian/ squeeze main contrib non-free" >> /etc/apt/sources.list
echo "deb-src http://ftp.it.debian.org/debian/ squeeze main contrib non-free" >> /etc/apt/sources.list
echo "deb http://ftp.it.debian.org/debian/ squeeze-updates main contrib non-free" >> /etc/apt/sources.list
echo "deb-src http://ftp.it.debian.org/debian/ squeeze-updates main contrib non-free" >> /etc/apt/sources.list
echo "deb http://security.debian.org/ squeeze/updates main contrib" >> /etc/apt/sources.list
echo "deb-src http://security.debian.org/ squeeze/updates main contrib" >> /etc/apt/sources.list
apt-get update
apt-get install flashplugin-nonfree icedove icedove-l10n-it ntp wireless-tools
apt-get --yes install linux-headers-2.6-686 build-essential module-assistant pulseaudio firmware-ralink
m-a update && m-a prepare
m-a a-i -t alsa-source

echo "speedstep_lib" >> /etc/modules
echo "tpm" >> /etc/modules
echo "tpm_bios" >> /etc/modules
echo "tpm_tis" >> /etc/modules
echo "auto lo" > /etc/network/interfaces
echo "iface lo inet loopback" >> /etc/network/interfaces
echo "allow-hotplug eth0" >> /etc/network/interfaces

Now you have a perfect business laptop with browser (firefox/iceweasel), email client (thunderbird/icedove) and openoffice (and whatever you want to install).

All hardware now works very well without any problem.
Enjoy.
