Cannot restore from Hibernation.

Asked by Stephen Smith on 2012-06-19

I am not sure if this is a "bug" or how to report it. I have a problem with Hibernation mode.

I have recently purchased a 17.3" HP Pavillion dv7-6c20us laptop with AMD A8-3520M apu (Quad core cpu plus Radeon HD 6620G gpu inside same chip @1.6Ghz), 6Gb RAM and 750 Gb Hard disk. I am using dual operating systems: Windows 7 Home Premium 64 bit and Ubuntu 12.04 LTS 64 bit.

I have noticed while using Ubuntu that if the computer slips into hibernation mode (screen goes dark) because of a very low battery charge or a long period of inactivity, the laptop will shut down. However, when I try to wake up the computer by brushing my finger across the Touchpad, nothing happens...the computer will not wake up. I try to touch various keys on the keyboard, but nothing works. On the occasion of low battery status, I will plug in the power supply and try to wake up the laptop. Still, nothing works. This has happened to me on four different occasions. This problem does not happen on Windows, only on Ubuntu.

In the desktop world, there is a manual reset override button you can push. On this laptop, there is NO RESET button. My solution to the problem was to remove the laptop's battery for a short period of time, and then reinstall the battery. THEN, the laptop will wake up and operate normally.

Does the system have a make and model?

Yes. As I mentioned in the second paragraph, I have purchased a Hewlett Packard Pavilion laptop (Model #dv7-6c20us). I bought this laptop from Newegg a little less than 2 months ago. However, Newegg has since removed this laptop from its inventory.
Anyway, since I have discovered a solution by removing the battery, this problem is not crucial ... more of an intellectual curiosity. I just thought that I should report this to the really smart guys.
