I recently bought a new HP Pavilion (dv7t-100 CTO) laptop, and installed Ubuntu Karmic 9.10 on it immediately. Everything seemed to work perfectly out of the box, including the function keys. Only problem is, Suspend and Hibernate definitely did not work. Any attempt to suspend or hibernate would basically corrupt the hard drive, and on the next boot (after a manual fsck), /home was wiped.
The solution was simple. No SMART hard drive tests (incidentally, a short SMART scan said the drives were OK). No drivers or kernel modules in Ubuntu. Simply a BIOS upgrade.
I simply had to download the BIOS update from the HP website, copy them to a USB drive, and boot into Windows to install the update. On next reboot, suspend and hibernate worked perfectly, and no more corrupted hard drives!

How to create multiple recovery disks for HP Recovery Manager
I recently purchased a HP Pavilion dv7 laptop. Since HP no longer ships recovery disks, and instead uses a recovery partition, my first step was to start the Recovery Manager and create some disks in case I needed to do a system restore later. However, HP only allows you to make one set of disks (thanks to IP laws) - and a set of disks had already been created by somebody. So I was pretty stuck.
However, there is a way to trick the program and create two (or more) sets of disks. There is a file named HPCD.sys located in both C:\WINDOWS\SMINST and the root of your recovery partition (in my case, E:\). Simply rename or delete these files (I renamed to HPCD.sys.bak) and HP Recovery Manager will quite happily create another set for you.
NOTE: In order to rename these files, you will have to go to Windows Explorer, press Alt+T to bring up the tools menu, click "Options". Go to the View tab, and select "Show hidden files and folders" and uncheck "Hide extensions for known file types" and "Hide system files and folders". Otherwise you won't be able to see the file!
You may also have to run Windows Explorer as Administrator - bring up the Start menu, right click Windows Explorer and choose Run As Administrator.
