## Configuration

### 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 4730s:

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

### Intel CPU microcode

See Microcode#Enabling Intel microcode updates.

### Network

Both the wired and wireless network cards 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 module, available in the official repositories.

#### 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. As it is working on 4330s and 4730s it should probably also on 4530s, 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, AMD Catalyst works well regarding GPU power management. Switching, however, requires a system reboot or Xorg restart. AMD Catalyst 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-ledAUR and synaptics-ledAUR 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. Memory Stick cards do not work, despite having module jmb38x_ms loaded. Dmesg does not show any info about Memory Stick card being inserted. 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) and Wi-Fi key has NoSymbol and does nothing.

#### Camera

Works with uvcvideo module.

#### HP DriveGuard

Works with hpfall-gitAUR package.

### Power

Module acpi-cpufreq and at least one of CPU governors (cpufreq_ondemand, cpufreq_conservative, etc.) are required. More informations on CPU frequency scaling.

Note: i915 module parameter i915_enable_rc6 can give up to 2 hours of additional battery life. However it is considered unstable and might cause crashes and graphical glitches. Add i915.i915_enable_rc6=1 to the kernel command line of your bootloader to try it.

- 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.
