Well.
I tested 2 or 3 times and with 5.5 it was a super fast resume from suspension. After a later test the same problem came. (I'm again updating the dmesg - This dmesg was generated after connecting to power once again, when I connect to the power plug everything resumes fine). I also had to switch from the nvidia graphics to the intel because the dkms didn't work for 5.5. I will also test the 5.0 with the intel card, just to absolutely rule out nvidia problems. To note again, only have these problems when resuming with battery unplugged. ** Attachment added: "dmesg.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1861595/+attachment/5326412/+files/dmesg.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1861595 Title: Laptop does not resume after suspend.

Everything works fine while plugged in. If power by battery it fails to resume (attached dmesg file). It gets stuck into the desktop but it's dysfunctional without disk operation. If I suspend in battery mode and then resume (that fails to resume properly) and then plug in the power supply the disk resumes perfectly and everything comes back to normal. It doesn't always replicate, but I would say 80% of the time.
