HP Pavilion ze5600
This document applies in particular to Arch Linux on an HP Pavilion ze5600 laptop. It may also apply to the entire ze5600 series on any modern Linux system (using at least kernel 2.6.39), and dependent upon what BIOS your system has.
Feel free to contact me if any problems or suggestions (lagagnon at gmail.com) (English or Spanish).
This laptop has as standard an Intel Celeron 2800MHz CPU, 512MB RAM (of which 446MB are available due to video chip RAM sharing), 40GB IDE hard drive, wireless, modem, DVD ROM optical drive, touchpad, multimedia keys, 15" LCD screen. Chip details:

What Works Without Any Configuration?
Ethernet, Audio, Microphone, Synaptic TouchPad, USB ports, optical drive, external video port (if booted with video device attached), CPU frequency scaling, Screen Brightness.
What Works With Minimal Configuration?
What Does Not Work?
Three of the upper multimedia keys, fn+f12, wireless off switch at front right of laptop, audio switches at right front side of laptop.
Not Yet Tested or Not Applicable
PCMCIA port, Modem.
Video: The older ATI chip in this laptop requires the xf86-video-ati "radeon" open-source driver. Apparently the latest drivers from ATI do not work with this chip. The radeon driver however, is fine. boot/grub/menu.lst: You should heed the Intel video changes and your menu.lst grub line for your kernel should have the following kernel parameters added:
Suspend/Hibernate: The "pm-suspend" and "pm-hibernate" scripts from the pm-utils package work just fine but you need to bind keys to access these scripts because fn+f12 has nos scancode.
Function Keys: Only two of the upper keyboard silver multimedia keys have scancodes. For information on how to bind keycodes please read Extra Keyboard Keys. Also, if many people have commented how annoying all those bright blue LED lights are right beneath the screen. I have placed black electrical tape over them and then with a razor knife cut around the tape to form the tape to the grill edges. It now looks as if those silly lights were never there!
Audio: Should just work. Read the "alsactl" man page to find out how to store alsamixer settings between reboots.
CPU Temperature: The lm_sensors package utility "sensors-detect" does not find any sensor chips. I read the file: /sys/devices/LNXSYSTM:00/device:13/LNXTHERM:00/thermal_zone/temp to get the CPU temperature. On ArhcLinux with kernel 2.6.39 I find that the laptop runs very hot. It starts at about 32degC and then continues to climb to 50deg C, with the fan on past 40degC, even at idle, with almost nothing doing. I have attempted many energy saving tools as per Laptop but to little avail. The laptop consumes about 25 watts at idle with the screen on at about mid brightness. As I have never run any other operating system on this laptop, I would love to hear if you have success in dropping the power usage and temperature level of this laptop.
Upgrading your BIOS
The BIOS upgrade download at the HP support website is a Windows only executable file and is designed to create bootable floppies. This is about as useless as tits on a bull as this laptop has no floppy drive (yes, it is really hard to understand the stupidity of HP sometimes)! To get it to flash under Linux you need to:
- Run the file as an executable under a MS Windows environment
- Rather than inserting a floppy use Windows Explorer to navigate to the directory where the extracted image was stored. NOTE::!!! Stuff below yet to complete!
- Use the undocumented "brick" repair method (below) proposed by Toshiba
As the first method is straightforward it will not be discussed here. Below is the alternate method outlined for Linux users (Note: you do this at your own risk - if done improperly you may permanently "brick" your laptop):
- the .exe file is a 7z compressed file. Use the command "7z e filename.exe" to extract. You may have to install a 7z package first.
- the only important file in the extract is the .fd file. Rename that file to "BIOS.fd"
- copy the BIOS.fd file onto the root directory of a USB flash drive
- remove any inserted CD, the power cord, the battery, and the hard drive from your laptop
- insert the USB flash drive into a USB port on your laptop
- simultaneously hold down the "Fn" and "F" keys
- plug in the power cord to the laptop while still holding Fn+F
- press Power On button of laptop while still holding Fn+F
- USB flash drive light should start to flash. You may now release the Fn+F keys after a few seconds
- leave laptop for about 1 minute. The ROM is being flashed. Your laptop will eventually turn itself off and it may reboot.
- you may turn off laptop now if it has rebooted successfully. If it just turned itself off then continue...
- unplug power cord, remove USB flash drive, replace laptop hard drive and laptop battery. Replug power cord.
- reboot laptop and enter the BIOS setup using "F2". You should see that it has successfully upgraded your BIOS.
