== Current Issues ==
## List any issues you have with the current development release here
The built-in microphone records sound, but the recordings are very scratchy and every half a second there is loud noise for a split second.

Wireless does not reactivate when disabled and enabled again using the hardware switch (I'll post a fix, when I found one out).
UPDATE: the following two commands seem to fix wireless after switching it off and on again, using the hardware kill switch. Before using these commands, make sure your WLAN adapter is the same as mine (Intel PRO/Wireless 3945ABG).
{{{
sudo rmmod iwl3945
sudo modprobe iwl3945
}}}
This effectively reloads the driver of the WLAN adapter. Until recently, this was not possible: the module could not be reloaded, because it was supposedly still in use. This seems to have changed with an update, I guess.

If you want the system to automatically reload the driver, whenever you disable wireless using the kill switch, do the following:

1. Open GEdit (or your favorite plain text editor) as root.
{{{
gksu gedit
}}}

2. Paste the following code into the text file:
{{{
 #!/bin/bash
KILL_SWITCH_ON=$(/usr/bin/udevinfo -a -p /sys/class/net/wlan0 | /bin/grep -c ATTRS\{rf_kill\}==\"2\")
if [ "$KILL_SWITCH_ON" != "0" ]; then
        sleep 3 && /sbin/rmmod iwl3945 && /sbin/modprobe iwl3945 &
fi
exit 0
}}}

3. Save the file to /etc/network/if-post-down.d/reload_iwl3945

4. Make the file executable:
{{{
sudo chmod a+x /etc/network/if-post-down.d/reload_iwl3945
}}}

5. Kill wireless with the kill switch. Wait approx. 5 seconds. Turn wireless on again. After a few seconds, the throbber in the system tray should start working and you should have a wireless connection shortly after.

=== Notes ===
## Add any notes here
The overall support of this notebook is very good. Almost everything works out-of-the-box. For anything else, there is this great blog: http://aldeby.org/blog/index.php/howto-ubuntu-linux-on-hp-pavilion-dv2000-dv6000-dv9000-series-laptops
There are many other interesting posts about Ubuntu and HP Pavilion notebooks on this blog, as well.

You might also want to check out this post to reduce battery consumption and CPU heat: http://ubuntuforums.org/showthread.php?t=786402
In my case, I could reduce the CPU voltage by 50% and the temperature went down by 12°C. Updating the BIOS to the latest version (F.53) decreases the temperature by another 5°C (but on the other hand, the fan does not turn off anymore (it is still very silent though)).

If you boot Ubuntu in battery mode (i.e., AC power is not connected), the fan is more silent (in case you do not update your BIOS). You can then plug-in the AC power connector.
