===== The bad contact in the DC connector =====

I learned that HP laptops are known to have very bad DC connectors subjects to bad contact. I had this problem, and I disassembled my laptop in order to solder back the connector.

First, an exploded view of the zv5340ea :

Unfortunately, you really need to completely disassemble the laptop to get access to the faulty solder. Some advice :
  * Completely remove the two screws under the DVD player, so that you can remove the DVD player by pulling it out of its place. There is a hidden screw that you can only access by removing the DVD player.
  * Once you've taken out all screws on the bottom, you can pull out the piece at the top of the keyboard (with power & wifi & multimedia buttons). You'll have to use some //brute force//. Finish removing all visible screws (and remember ;-)).
  * If you want full access to the connector (and not only the solder), you'll have to remove also 4 big screws with springs that maintain the dissipator on the processor, and 3 little screws that maintain a small steel plate on the other side of the mainboard.

  * To unplug the keyboard, the touchpad, and the facade buttons, try to pull the brown part before removing the ribbon cable.

  * Disassemble the screen, and take the wifi card out (let it connected to the screen, it's the antenna). Unplug the fans too.

My DC connector solder looked that :

{{  bad_contact.jpg  }}

So it was pretty obvious what was the problem. Unfortunately, the wire of the connector was very hostile to tin. I had to heat a lot to make the solder, I did it twice and each time the bad contact was back after one month.

The third time, I completely removed the connector, cleaned all the wires, and resoldered it properly. For now it resists.

I had also a bad contact in a USB connector, and some soldering made it also.

===== With Linux =====

==== Multimedia keys ====

You can catch up most of multimedia keys of your laptop under Linux, with ''lineakd''.

''/etc/lineakb.def'' already contains some codes of keys for HPzv5000, but with ''xev'' you can find more :
<code>
[HPzv5000p]
 brandname = "Hewlett-Packard"
 modelname = "Pavilion zv5000"
 [KEYS]
   Mute        = 160
   VolumeDown  = 174
   VolumeUp    = 176

   WWW         = 178
   FnWWW       = 233
   FnMusic     = 234
   FnPhoto     = 178 # Same as WWW !

   PlayPause   = 162
   Previous    = 144
   Next        = 153
   Stop        = 164

   Suspend     = 223
   Pause       = 110
   ScreenShot  = 111
   Attn        = 37  # Same as Control_L !!
   Popup       = 117

# caution, prevent keys from acting normally
   Win         = 115
   FnWin       = 116
   WinG        = 115
   WinD        = 116
 [END KEYS]
[END HPzv5000p]
</code>

And then for example in ''/etc/lineak/lineakd.conf'' :
<code>
   Mute        =amixer sset Master toggle
   VolumeUp    =amixer sset Master 1+
   VolumeDown  =amixer sset Master 1-

   WWW         = "firefox"
   FnWWW       = ""
   FnMusic     = ""

   PlayPause   = "audacious -t"
   Previous    = "audacious -r"
   Next        = "audacious -f"
   Stop        = "audacious -s"

   Suspend     = "gksudo hibernate-ram"
   ScreenShot  = ""import -window root `date +/home/cyril/screenshots/shot-%Y-%m-%d_%H-%M-%S.png`
   Popup       = ""
</code>

==== Touchpad ====

HP zv5000 laptops have a Synaptics touchpad (this is the case of a lot of laptops). You can dowload the synaptics driver (there is a gentoo package, and probably for other distributions), and use it instead of the default driver. It allows you to configure a lot of things, for example disabling the click on tap when you are typing.

=== Install the driver ===

<code>
emerge synaptics libsynaptics
</code>

You have to modify your xorg.conf to use the driver :

In ServerLayout section : <code>InputDevice    "Touchpad"  "AlwaysCore"</code>

In Module section : <code>Load  "synaptics"</code>

And finally add the section :
<code>
Section "InputDevice"
  Identifier   "Touchpad"
  Driver "synaptics"
  Option "Device"  "/dev/input/mouse0"
  Option "Protocol" "auto-dev"
  Option "LeftEdge"      "20"
  Option "RightEdge"     "990"
  Option "TopEdge"       "20"
  Option "BottomEdge"    "730"
#  Option "FingerLow" "25"
#  Option "FingerHigh" "30"
  Option "MaxTapTime" "150"
  Option "MaxTapMove" "150"
  Option "MaxDoubleTapTime" "100"
#  Option "SingleTapTimeout" "50"
  Option "FastTaps" "1"
  Option "VertScrollDelta" "100"
  Option "MinSpeed" "0.25"
  Option "MaxSpeed" "0.80"
  Option "AccelFactor" "0.025"
  Option "SHMConfig" "true"
  Option "UpDownScrolling" "1"
#  Option "RTCornerButton" "0"
#  Option "BTCornerButton" "0"
##  Option "Repeater" "/dev/input/mouse0"
EndSection
</code>


=== Configure the touchpad ===

As you can see in the example of my xorg.conf there are a lot of options you can configure.

You can get a list of them with current values with 
<code>synclient -l</code>

You can get some extra info (for example x,y,z position of your finger) with
<code> synclient -m 100</code>

You can modify it to test it with 
<code>synclient MaxTapTime=150</code>
and then put it in xorg.conf when you are sure of your modification.

== Tips ==
  * To have vertical scrolling on the edge (and horiz scrolling too), you have to set RightEdge LESS than the maximum you can have with ''synclient -m 100'', because it scrolls OUTSIDE of your declared touchpad size.

=== Use the daemon ===

The daemon permits you to have more advanced features, such as disabling click on tape when typing.

You can run it for example with the command (see man page)
<code>syndaemon -t -d -k -i 2</code> 

==== Wireless Broadcom BCM4306 802.11b/g ====
=== With the linux driver ===

Since 2.6.17-r2 kernel, linux supports Broadcom 43xx wifi cards.

First, enable options in the kernel config and recompile it :
<code>
Networking
--> Generic IEEE 802.11 Networking Stack
--> Software MAC add-on to the IEEE 802.11 networking stack

Device Drivers 
--> Network device support 
--> Wireless LAN (non-hamradio) 
--> BroadcomBCM43xx wireless support 
--> BCM43xx data transfer mode (DMA+PIO)
</code>

You have also to install the driver and ''wireless-tools'' :
<code>
emerge bcm43xx-fwcutter
emerge wireless-tools
</code>

Then find on your windows partition or download on the web your windows driver ''bcmwl5.sys'', and excute the following line :
<code>
mkdir /lib/firmware
bcm43xx-fwcutter -w /lib/firmware bcmwl5.sys
</code>

(the path can change if not gentoo, see [[http://acx100.sourceforge.net/wiki/Firmware]])

And finally either reboot or type :
<code>
rmmod bcm43xx
modprobe bcm43xx
</code>

To use it :
<code>
ifconfig eth1 up
iwconfig eth1 essid on
iwlist eth1 scan
iwconfig eth1 essid "name-of-the-essid-you-want"
</code>

Or more simply with gentoo :
<code bash>
cp /etc/init.d/net.eth0 /etc/init.d/net.eth1 # the first time
/etc/init.d/net.eth1 start                   # each time
</code>

== Note ==
If your eth0 (ethernet card) is up, don't forget to disable it to use wifi, because Linux will still try to use it even if there is no cable :
<code bash>
ifconfig eth0 down        # for linux users
/etc/init.d/net.eth0 stop # for gentoo users
</code>

=== Using WPA ===

Install ''wpa_supplicant''.

Configure your network in ''/etc/wpa_supplicant/wpa_supplicant.conf'' :
<code>
network={
   ssid="my-ssid"
   psk="my-pass-phrase"
   key_mgmt=WPA-PSK
   proto=WPA
 }
</code>

And finally in ''/etc/conf.d/net'' :
<code>
config_eth1=( "dhcp" )
modules=( "wpa_supplicant")
wpa_supplicant_eth1="-Dwext"
</code>



And you're done !

=== With ndiswrapper ===
This was the way to have wifi working before the kernel module, but it still works.

== Installation ==
As root :
<code bash>
emerge ndiswrapper
# get bcmwl5.inf and bcmwl5.sys from windows installation
ndiswrapper -i /path_to_bcmwl5/bcmwl5.inf
</code>

== Activation ==

As root :
<code bash>
modprobe ndiswrapper     # to load ndiswrapper (have wlan0 in iwconfig)
iwconfig wlan0 essid on  # to activate the card
dhclient wlan0           # DEBIAN-based : to get the ip
dhcpcd -n wlan0          # GENTOO-based : to get the ip
ifdown eth0              # to oblige to use wifi if eth0 is connected

sudo iwlist wlan0 scanning    # to see wifi networks
</code>



==== Nvidia drivers for GeForce4 440 Go ====

To have 3D acceleration, compile xorg with these flags in ''/etc/make.conf'' :
<code>
USE="aiglx dri" # or aiglx in package.use : xorg-server aiglx
VIDEO_CARDS="nvidia"
</code>

Then (you have to do it each time you rebuild your kernel) :
<code>
emerge nvidia-drivers
</code>

The video card is not compatible with drivers >= 100.0.0 (uses legacy driver, with version number < 100), so gentoo users have to add ''>=x11-drivers/nvidia-drivers-100.0.0'' in ''/etc/portage/package.mask'' to not be bothered by updates.

Finally in ''/etc/X11/xorg.conf'', set ''nvidia'' instead of ''nv'' for the driver in the ''Device'' section, comment ''dri'' in options and add ''glx''.
