use ubuntu which is well supported and stable.
download or request free cd here
http://www.ubuntu.com/
ubuntu 10.04, do not get beta version.
in my experience, i use ubuntu on HP or HP/Compaq laptops with all intel inside.
it works well out of the box.
HP fully support linux, expect it to be a perfect laptop.
no overheating, charging is perfect, hibernation, wi-fi touchpad, usb port,, just about every hardware works, games music, no problem, torrents etc etc..
after installation, you will go to system>administration>update manager
wait for update to finish.
using ubuntu or any other distro without downloading/updating right after installation
will really give you problem because application is not yet fully installed. files are incomplete. so you need to update it.
on your linux now, try to reinstall the cd or just update it manually.
