Bug Description
My Dell Precision 5510 laptop has recent drivers for graphics. I installed a lot of updates this week, and I have been finding that the laptop shuts down in the "Suspend" state if at any point AC power is unplugged.
Steps to reproduce:
1. With laptop plugged in to AC power and Ubuntu running, use the GUI to enter the suspend state.
2. With the laptop suspended, unplug AC power.
3. Plug in AC power again.
4. Press the ACPI power button to trigger a wake from suspend.
Expected behavior:
Login screen to resume the pre-suspend session.
Actual behavior:
Laptop goes through POST. During startup, fsck-like text flashes on the screen indicating that a "hard shutdown" occurred.
What I've done:
(I boot with GRUB from an encrypted LVM partition.) My grub config already has the "acpi_sleep=nonvs" option from the last time I had a suspend-related issue. Most online fora will recommend this as a fix, but I am still having these problems. I even re-ran grub-update just to be sure.
