Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.8 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Last post should end Nevertheless KERNEL=4.8.0-040800rc5-generic is now running, so next we test suspend... (A solution to Bug https://bugs.launchpad.net/launchpad/+bug/119420 would be grand)

Following the last post we have upstream success; so far after suspend is selected from Whiskermenu the laptop closes down with the green LED on the power button blinking every few seconds.

On Power button press the machine restarts quickly with so far no bad side effects noticed.

Setup is...

kernel-fixed-upstream should read kernel-semi-fixed-upstream as suspend fails every second attempt

Below is the observed behaviour and how it could be implemented using an 'object' that could be a flag set in a file on persistent media such as a hard disk

1a Whiskermenu Shutdown to switch PC off
1b Briefly press in power switch say for 2 secs to switch PC on
1c Object is set to 0 (capturing fact PC has just come out of completely powered down state)
1d Wait about 3 minutes
1e Observe PC works normally

2a Via whiskermenu select Suspend
2b If Object is set to 1 don't suspend (ignored)
2c Object is set to 1 (capturing fact suspend has been used once)
2d Green power LEDs (on power switch and on front of case) blink together every 3 seconds approximately.
2e No other LEDs are on
2f Observe PC behaves as if suspended

3a Briefly press in power switch say for 2 secs to resume from suspend
3b Alternative place to set Object to 1
3c Observe PC resumes normally

4a Via whiskermenu select Suspend
4b If Object is set to 1 don't suspend (actioned)
4c Observe PC hangs with power switch LED on and front power LED both green and constant
4d also yellow LED on mute speaker key is on
4e Brief presses on power button and Ctrl Alt Del etc have no affect
4f Only option left is press and hold Power button for about 6 secs to switch PC off

Not yet adopted suggestion was to update the BIOS
