Title:
[HP Compaq dc7800p Small Form Factor PC] suspend/resume failure
Status in linux package in Ubuntu:
Incomplete
Bug description:
To reproduce this bug I go to the shell as root and execute pm-suspend.
Suspend to RAM fails to wake up on my HP dc7800p. After suspending with
pm-suspend an attempt to wake the machine up with the power button leads to a
black screen. The video card does not appear to show any activity to my
monitor. I must hold the power button down for 6 seconds to power off and boot
the system back up.
This system is using the on-board intel graphics. If I put an nvidia
card into the machine it is able to suspend and resume without issue.
I have observed that if I pm-hibernate and resume from that
hibernation the system is able to pm-suspend resume successfully.
I tested this but exists in an Ubuntu 14.04 installation. I have not
tested or used it with older distributions.
