HP Pavilion dv6 laptop frozen after closing lid

I just finished installing Ubuntu 10.10 last night. Today, while in Ubuntu I shut the lid of my lap top because I had to hurry to take care of something.

When I attempted to reopen the laptop and start using it again I had to turn it on via the power button which was odd. It was also odd that it appeared to come back on, but the screen stayed off.

The fan spins up and is going harder than usual and the keyboard seems unresponsible. I've tried Ctr + Alt + F keys to try and see if that was the issue, but no luck so far.

I've seen this question asked for this model as I looked for solutions and have never seen a solid answer to it. I would -really- appreciate any feedback possible.

Edit: The laptop is an HP Pavilion dv6 running with an AMD64 processor.

 

Don't shut the lid.

Alternatively, like the following bug report you could try fetching and building a later kernel to see if that fixes the problem.

What kind of video card do you have?

You can change the lid action to 'nothing' using gconf-editor to prevent it from suspending or blanking when the lid is closed (see the attached screenshot):

Code:

gconf-editor /apps/gnome-power-manager/buttons/

It may forcibly blank from the BIOS when the lid is closed - ASUS systems tend to do this. I'm not sure about HP.

If the screen fails to come back after suspend, you can manually try different quirks for pm-suspend. See the pm suspend manpage ( man pm-suspend).

For example see --quirk-dpms-on or --quirk-vbe-post

You can also install the uswsusp package and see if s2ram --force works any better.

After a forced poweroff you may want to run fsck (file system check). You can force one at startup with:

Code:

sudo -s
>/forcefsck

or

Code:

sudo sh -c ">/forcefsck"

or

Code:

sudo touch /forcefsck

 

Possible sleep/hibernate issue with the current kernel?
