Laptop wakes up seconds after suspend

rubiconjoe

I'm not sure if this is an Ubuntu issue or hardware issue but, I am running a Toshiba Satellite L745 with Ubuntu 20.04. Seconds after I put the machine to sleep or close the lid, it wakes up by itself. I have checked power settings in the BIOs and tried different options but the issue is still present. Is there a log to show what triggered the system to wake up? Any troubleshooting steps would be much appreciated.

I recently re-installed Ubuntu mainly to try and fix this and other issues. The machine has a fresh install, no alterations to default settings.

Thank you,

Joe

Troubleshooting so far:

Output of: cat /proc/acpi/wakeup | grep enabled

EHC1 S3 *enabled pci:0000:00:1d.0
EHC2 S3 *enabled pci:0000:00:1a.0

ECH1/ECH2 will not toggle to disabled. These lines refer to two USB Host controllers per: lspci command. Not sure where to go from here.

I also read in forums for the issue of machine not going into deep sleep.

Output of: cat /sys/power/mem_sleep s2idle [deep] Seems it is in the correct mode.

Any further troubleshooting steps would be much appreciated.

Trying to make sense of the syslog. Any help would be much appreciated.
