HP 635
This page describes the HP 635 laptop (product number LH415EA#ABD) and how to use it with Debian GNU/Linux.
This is a quite inexpensive laptop (among other things, because it's not shipped with Microsoft Windows), I paid €289.-.

HOWTO
CPU
Works fine, see /proc/cpuinfo for details. CPU frequency scaling using cpufrequtils works fine too, see cpufreqinfo for details.
Graphics
Works fine out of the box. You need the firmware-linux package, though.

Audio
Works fine using the snd-hda-intel kernel module. I had to change the default card though, so that alsamixer etc. work out of the box:
$ cat /etc/asound.conf
pcm.!default {
type hw
card 1
}
ctl.!default {
type hw
card 1
}
$ cat /proc/asound/cards

Hard drive
Works fine, of course. It's a Hitachi HTS543232A7A384 320GB SATA 2.5" drive.

Touchpad
Works out of the box, both in X11 and via gpm in the console.
$ dmesg | grep -i synaptics Synaptics Touchpad, model: 1, fw: 7.5, id: 0x1e0b1, caps: 0xd00073/0x240000/0xa0400 input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input8
Some "scrolling when dragging with two fingers" and similar stuff seems to work fine. You can configure various other touchpad settings using gpointing-device-settings. However, the tapping feature doesn't seem to work for me, not sure why. You can manually fix this by running synclient TapButton=1.
Keyboard
Works fine. I prefer to set/uncomment the KEYBOARD_RATE/KEYBOARD_DELAY settings in /etc/kbd/config (do /etc/init.d/kbd restart afterwards):
KEYBOARD_RATE="30" KEYBOARD_DELAY="250"
Some special keys such as Fn+F2/F3 for adjusting brightness work fine, haven't tested all of them yet, though.
Ethernet
Works out of the box using the r8169 driver.
$ dmesg r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded r8169 0000:06:00.0: PCI INT A -> GSI 21 (level, low) -> IRQ 21 r8169 0000:06:00.0: setting latency timer to 64 r8169 0000:06:00.0: irq 43 for MSI/MSI-X r8169 0000:06:00.0: eth0: RTL8105e at 0xffffc90000664000, aa:bb:cc:xx:yy:zz, XID 00a00000 IRQ 43
Wifi / Bluetooth
I did a quick test of the wifi hardware using kismet (source=ath5k,wlan0,WLAN), no real wifi connections yet.
The Linux driver ath9k is used for wifi, ath3k is used for Bluetooth.
$ dmesg | grep -i ath ath9k 0000:07:00.0: PCI INT A -> GSI 23 (level, low) -> IRQ 23 ath9k 0000:07:00.0: setting latency timer to 64 ath: EEPROM regdomain: 0x60 ath: EEPROM indicates we should expect a direct regpair map ath: Country alpha2 being used: 00 ath: Regpair used: 0x60 ieee80211 phy0: Selected rate control algorithm 'ath9k_rate_control' Registered led device: ath9k-phy0 ieee80211 phy0: Atheros AR9285 Rev:2 mem=0xffffc900050a0000, irq=23

The rfkill tool works fine for soft-blocking wifi/Bluetooth (and displaying the status), as does the Fn+F12 key combination.

Webcam
Works out of the box using the uvcvideo driver and a viewer such as mplayer tv:// or luvcview or cheese.

Reading CDs/DVDs works out of the box. Writing CDs/DVDs is untested so far.

Suspend
I tested suspend-to-disk and suspend-to-RAM via hibernate-disk / hibernate-ram, both seems to work fine.
