Ubuntu 12.10 made the display on a HP Compaq 8510w flicker and go
black. This happened with the setup, nouveau driver i guess.
I reinstalled with Fedora - it worked fine.
I did a new installation with ubuntu 12.10 - flickering problem
persisted, but it worked on external monitor - but somehow, after
some reboots, the laptop is completely dead.
Now, it doesn't boot - only blinks with the HDD and Ethernet leds.
I can see in my router, that it doesn't acquire a dhcp address - but
it registers the MAC address 01:00:5E:00:00:FB
Perhaps something has messed with the Intel AMT settings or system BIOS ?
I tried taking out and replacing the motherboard battery.
Does anybody know how to get in touch with the Intel AMT and do a
reflash to factory settings ? (That is my guess for a solution.)
I'm no longer on support with HP.
I logged a bug with Ubuntu - but no reaction yet.

That reads like a hardware failure to me. Unfortunately it will
probably need to be repaired or replaced.

While Ubuntu is a fork of Debian and many things are therefore similar
the Linux kernel in Ubuntu is a much different version than the one in
Debian. Debian Stable Linux kernel version is 2.6.32 while Ubuntu's
12.10 Linux kernel is IIRC a 3.4 version. There have been a lot of
changes there and they do their own packaging. This is an area where
I would make no assumption about them being similar. You need Ubuntu
Since you were using Ubuntu already it really only makes sense to use
Ubuntu resources to debug it. Because reading your report you never
mentioned installing Debian on your system so I don't see how this
involves Debian any more than if you had installed Gentoo or Arch.
The Linux kernels in those Gentoo and Arch are much more similar to
Ubuntu than Debian.
