Okay, you neglected to tell us if this is the first time
you have tried to install any sort of Linux upon this laptop!
Presuming that this is
the first time, I will say that the first thing to try is to look for any sort of BIOS-upgrade that may be available from HP for this particular model.
A Google search on "hp dv5000 bios" produced about 400 hits which strongly suggest that you are not alone.
Here's the soap... ACPI, as you may know, is a very sophisticated technique that laptops use to describe themselves: what hardware they have, where the internal switches-and-buttons are located, and exactly how an operating-system should push them. (So to speak.) You have
to use ACPI.
Anyway... the ACPI information is actually a program
, written in an interpreted language that Linux (and Windows) knows how to interpret. By running this program, the OS can build up a very detailed picture of this computer, and can control it.
But sometimes, there are bugs in that information. Most of the time, "BIOS upgrades" actually consist of patches to it. There can also be the issue (now mostly historical) that manufacturers used Microsoft's compilers and those compilers had a few small bugs in them. When the Linux interpreter was written, they followed the latest specifications exactly. Microsoft was working on it before the specs were quite finalized, and there were a few glitches that "got by."
There are amazing things that you can
do to bypass ACPI problems, including extracting the information out of the BIOS ROM, decompiling it, patching the source-code, recompiling it, and telling Linux to use that.
let's hope you don't actually have to do that. Let's hope that HP does
have a BIOS upgrade.
If they do, it'll consist of a program you can run (uhh, on Windows, "natcherly"
) which will build a floppy-disk that you can then boot. Which will replace the BIOS in "flash ROM."
Been there, done this. Good... luck.
