Known Problems
BIOS and eth0
There is a known fault with some revisions of the BIOS which for Linux mean the Ethernet port (eth0) is only detected if the laptop is connected to mains power when it boots. The solution to this is to install BIOS revision F.02 (released in March 2009). It appears that only this BIOS revision fixes the problem as the same problem occurred on a laptop with BIOS revision F.04.
For details of the fix and to download the BIOS update, go to an official HP web site and search for "2140" and "linux" and navigate to the "Download drivers and software" support section for this product. Details of what has been fixed in the various revisions is available on the "Revision History" tab/section.
For BIOS revision F.02 the site states "Fixes an issue that occurs on notebooks running a Linux operating system that are using battery power (DC power) with a LAN cable plugged in, where the wired network controller (NIC) is not recognized by the system when the notebook is booted."
