Nikola Yanchev, thank you for reporting this and helping make Ubuntu better.

In order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Also, you don't need to apport-collect further unless specifically requested to do so.

It is most helpful that after testing of the latest upstream kernel is complete, you mark this report Status Confirmed.

Lastly, to keep this issue relevant to upstream, please continue to test the latest mainline kernel as it becomes available.

Thank you for your help.

It is not related to Ubuntu and N752vx (my N752vx is affected too with OpenSUSE).

Lots of ASUS notebook affected with this strange issue, more information: https://bugzilla.kernel.org/show_bug.cgi?id=108801

[penalvch (penalvch)]

Gábor Auth, if a Ubuntu user reported a bug about it, then it is clearly related to Ubuntu. How many notebooks you think this issue doesn't change this.

[Gábor Auth (auth.gabor)]

Even if it is a firmware bug related to Skylake architecture? I don't think so but I keep my fingers crossed for you to fix it. :)

[Gábor Auth (auth.gabor)]

FYI: Downgrade from recent BIOS to version 203 fixed the iusse. The following BIOS versions are contain this bug: 204, 300, 301.

[penalvch (penalvch)]

Gábor Auth, it will help immensely if you filed a new report with the Ubuntu repository kernel (not mainline/upstream) via a terminal:
ubuntu-bug linux

Please feel free to subscribe me to it.

I experience absolutely the same problem after upgrading to Kubuntu 18.04. I am using Dell Latitude e5570 laptop and everything worked fine on 16.04. Please let me know what info is needed to investigate the problem.

# uname -a
Linux latitude 4.15.0-20-generic #21-Ubuntu SMP Tue Apr 24 06:16:15 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

# sudo lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu

[Alex (alex-khv)]

Found a workaround in the Internet. Boot your laptop on battery, then shutdown it (not reboot) and boot again. Then suspend starts working on battery too.

[penalvch (penalvch)]

Alex (alex-khv), it will help immensely if you use the computer the problem is reproducible with, and provide necessary debugging logs by filing a new report with Ubuntu via a terminal:
ubuntu-bug linux

Please feel free to subscribe me to it.

[Luís Correia (luis-correia)]

Dell XPS 13 9350 upgraded from 16.04 to 18.04 had the same problem.
Used solution provided by Alex on post #10 and it's fine now.

[penalvch (penalvch)]

Luís Correia, you don't have the same problem as this report is not scoped to 18.04, or any Dell machine.

Hence, if you want your problem addressed, use the computer the problem is reproducible with, and provide necessary debugging logs by filing a new report with Ubuntu via a terminal:
ubuntu-bug linux

Please feel free to subscribe me to it.
