The HP 530 laptop works quite well with debian lenny. I was really amazed how quick I got a nearly perfect system up and running.

Resize old partitions

I used the windows-vista disk-management tools from the mmc to resize the original NTFS partition (OK - I'm coward - I did not completely erase that crap ;-)

Install

Simply do a basic debian lenny net-install.
Nearly all works out of the box! Lounch-keys, hibernate, ...

XOrg

Works at 1280x800 with the latest kernel: 2.6.24-1-686

WLAn

works fine with the iwl3945 driver and the firmware-iwlwifi package

ACPI and Suspend

Hibernate works out of the box, to get suspend working, I had to edit the following files:

/etc/hibernate/ususpend-ram.conf.conf

changed:

USuspendRamForce yes
USuspendRamVbeMode yes
USuspendRamVbePost yes

and

/usr/lib/pm-utils/defaults

changed:

S2RAM_OPTS="-f -m -p"

hwclock

# hwclock -r
select() to /dev/rtc to wait for clock tick timed out

to fix this, change HWCLOCKPARS="--directisa" in

/etc/init.d/hwclockfirst.sh
/etc/init.d/hwclock.sh

TODO:

According to Mr. Murphy one big problem ist still left: The lid-button is not raising any ACPI-event. Strange phenomena: after a hibernate and successful resume it works!
