[Lenovo ThinkPad T450s] Suspend is not triggered by closing lid while DisplayPort monitor connected

[James Ferguson]

The laptop does not suspend on closing the lid, if a DisplayPort monitor is connected. It does suspend normally on closing the lid if no external monitor is connected.

Syslog notes:
Dec 13 21:19:11 down kernel: [ 1627.804109] i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment

WORKAROUND: Suspend using method other than lid-closing, e.g. using the System Menu on the desktop.

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 v4.9 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.

[James Ferguson (james-ferguson)]

AFAIK issue has always been present. Will try the upstream kernel.

[James Ferguson (jamesf)]

Yeah, upstream kernel 4.9.0-040900 does not fix the problem. Happy to help debug in any other way.

[James Ferguson (james-ferguson)]

Description was updated to be totally inaccurate. The problem is that the laptop does not suspend when the external monitor is attached. The problem is *not* that it doesn't resume from suspend.

The bug is that it will not suspend when the monitor is attached and the lid is closed. To suggest disconnecting the monitor as a workaround is somewhat unhelpful and akin to the old doctor joke of "it hurts when I do this", "then stop doing that".

James Ferguson:

>"Description was updated to be totally inaccurate."

The original Description you inputted originally was precisely:
"The laptop appears to suspend/resume fine stand-alone, but if a DisplayPort monitor is connected, it does not."

Please take care when creating bug reports going forward, so folks don't become confused as to the exact bug reproduction scenario.

>" To suggest disconnecting the monitor as a workaround is somewhat unhelpful"

A WORKAROUND is not a suggestion but a fact, and helpful for those folks who want to suspend now while waiting for a fix to be developed.

Despite this, as per http://support.lenovo.com/us/en/products/Laptops-and-netbooks/ThinkPad-T-Series-laptops/ThinkPad-T450s/20BX?tabName=Downloads&linkTrack=Mast:SubNav:Support:Drivers%20and%20Software|Drivers%20and%20Software&beta=false an update to your computer's buggy, insecure, and outdated BIOS is available (1.27). When you update to this following https://help.ubuntu.com/community/BIOSUpdate how does this improve the situation?

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful.

Also, you don't have to create a new report.

It is most helpful that after the BIOS is updated, if the problem is still reproducible:
1) Please provide the output of the following terminal command (not perform an apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on how this improves the situation.
3) Please mark this report Status Confirmed.

If it's not reproducible, please mark this as Invalid.

Thank you for your help.

[James Ferguson (james-ferguson)]

My description was ambiguous; it did not explicitly state that suspend was not *initiated*, rather than suspend/resume failing. I apologize for the confusion caused. I think I have updated it to make the issue more clear.

Your workaround would have been helpful if the transformation you made to the nature of the bug was accurate. Again, I apologize for creating an ambiguous description, but I would suggest asking the submitter for clarification in such a case.

I will update the BIOS and check it out. Thank you for your efforts and I am sorry that I did not create a clear description initially. It's often difficult to perceive how your words may be misconstrued but I could definitely have taken more care in the submission.

[James Ferguson (jamesf)]

Unfortunately, the BIOS/UEFI update did not improve the situation. Suspend is still not triggered when the lid is closed, IF a (DisplayPort) monitor is attached.
