Reason: Hardware table needs IDs, a function keys section should also be added (Discuss in Talk:HP ProBook 4330s)

Hardware | PCI/USB ID | Working?
--- | --- | ---
GPU |  | Yes
Audio |  | Yes
Ethernet |  | Yes
Wireless |  | Yes
Bluetooth |  | Untested
Touchpad |  | Yes
Card reader |  | Yes
Webcam |  | Yes

## Fan throttling

The fan can be controlled (throttled) in software, otherwise it never shuts off, even if the BIOS option "Fan always on while on AC power" is disabled. There are two programs supporting the 4330s:

- NoteBook FanControl
- probook_ec.pl script daemonized in Python and in Ruby

## Synaptics Touchpad

The `xf86-input-synaptics` driver is needed (see Touchpad Synaptics) for the touchpad to work, but the pointstick works out of the box.

## WLAN BIOS whitelist workaround

HP BIOS allows only certain WLAN cards (whitelisting) to be used. This can be worked around by adding the following as the first GRUB command in every OS entry:

    write_dword 0xFED1F418 0x1F501FEB
