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 4530s:
NoteBook FanControl
.
NBFC
have pre-made profile for HP ProBook 4530s.

Network
Both the wired and wireless network cards (with the exception of the ralink RT3592 and RT3590) works out-of-the-box. The Atheros card requires the
ath9k
module, and the Realtek Ethernet card requires the
r8169
module. More information can be found at
Wireless network configuration#ath9k
Note
With some revisions of this Realtek Ethernet card, better performance may be obtained with the Realtek provided
r8168
AUR
module.
WLAN BIOS whitelist workaround (experimental)
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
You can read more on engineering this hack
here
. It is confirmed to work on the 4330s, 4530s and 4730s, but consider it experimental.
Bluetooth
Sending/receiving files and switching Bluetooth on/off works. The
ath3k
module is required.

Graphics
Intel HD Graphics 3000 is supported by the open-source
xf86-video-intel
driver. Dual-head with HDMI works. If using hybrid graphics in conjunction with AMD, open-source
ATI
driver should be used for GPU card (proprietary driver is not available, see
Graphics processing unit#AMD (ex-ATI)
). For
dynamic switching
can be used
PRIME
technology. ATI driver should be installed along with
xf86-video-intel
to support hybrid (Intel) GPU.
Brightness
Controlling screen brightness with the keystrokes
Fn+F2
and
Fn+F3
works in Gnome 3, KDE and MATE and has not been tested in other desktop environments.
Touchpad
Touchpad function works with
xf86-input-synaptics
package. Disabling touchpad using the top-left corner double tap works with
xf86-input-synaptics-led
AUR
and
synaptics-led
AUR
(
synaptics-led-dkms
AUR
) packages.
Miscellaneous hardware
Card reader
23:00.0 System peripheral: JMicron Technology Corp. SD/MMC Host Controller (rev 30)
23:00.2 SD Host controller: JMicron Technology Corp. Standard SD Host Controller (rev 30)
23:00.3 System peripheral: JMicron Technology Corp. MS Host Controller (rev 30)
SD cards tested and working. With 3.4.7 kernel, Memory Stick card works as intended.
Function keys
Module
hp-wmi
is likely to be required for the keys to work. In Gnome 3 and MATE every
Fn+F*
key works.
Fn-F6
key requires gnome-power-manager installed.
Keys above numeric keypad are also recognized. The
Web
key has a XF86HomePage symbol (opens home page),
Wi-Fi
key has NoSymbol and switch fly mode in Gnome 3 (has not been tested in other desktop environments).
Camera
Works with
uvcvideo
module.
HP DriveGuard
Works with
hpfall-git
AUR
package.
Power
Module
acpi-cpufreq
and at least one of CPU governors (
cpufreq_ondemand
,
cpufreq_conservative
, etc.) are required. More information on
CPU frequency scaling
.
Note
With laptop-mode-tools, tune from powertop2 and
i915_enable_rc6
parameter I was able to get about 5:30h of estimated battery life.
Keep in mind that the powertop "good/bad" parameters will not survive a reboot.
As of 3.4.x
rc6 is enabled by default for Ivy Bridge and Sandy Bridge processors.  The default (marked -1) is equivalent of
i915_enable_rc6=3
which enables rc6 and rc6p.  An additional, lower power state can also be enabled by using
i915_enable_rc6=7
, though this has been reported to sometimes come at the cost of stability.  Also, as of
2011Q4
the i915 module in Sandy Bridge and Ivy Bridge also have framebuffer compression enabled by default.
Suspend and hibernation
Both suspend and hibernation work with pm-utils and kernel backend.
Sensors
lm_sensors
shows one acpitz-virtual device with 4 working temperature readings and coretemp-isa device which has one sensor for each CPU core.
It does not show any info about fans RPMs.
