HP ProBook 4330s
|Fan is throttled||No|
The hardware support is indicated in the table on the right.
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:
Intel CPU microcode
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
