Comment 324 for bug 272247

With much thanks to 67GTA (MUCH much thanks) we now have a working DSDT.aml for the G6062ea laptop from HP.

download the attatched file, copy it to /etc/initramfs-tools/ and then run the command

"sudo update-initramfs -u -k kernel-version"

in a terminal substituting "kernel-version" for your actual kernel version (you can find this from "uname -r") (my command was "sudo update-initramfs -u -k 2.6.28-11-generic") You then need to also edit /boot/grub/menu.lst (that's lower case LST, btw) and put in:

acpi_osi="Linux"

On the kernel line, then save and run "sudo update-grub"
example version:

title Ubuntu 9.04, kernel 2.6.28-11-generic
