Laptop wakes up immediately after suspend

My laptop wakes up immediately after suspend (or it fails suspending? are they two different cases?). It is an old Toshiba Satellite C855D-S5105, 8Gb RAM. It has a recently installed bodhi Linux (an Ubuntu derivative, so for many many things it works the same as Ubuntu). None of the solutions I found works. The two candidates in BIOS are disabled (*Wake on LAN* and *Wake on Keyboard*). There is a touchpad too, no mouse or bluetooth receiver. Below I am posting relevant info, with sources. $ uname -a Linux Orion 5.4.0-107-generic #121-Ubuntu SMP Thu Mar 24 16:04:27 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux Trying to identify candidates for the wakeup (assuming it suspends and wakes up).
Here there seem to be some devices enabled for wakeup (see this ). $ cat /proc/acpi/wakeup | grep enabled Device S-stateStatus Sysfs node OHC1 S3 *enabled pci:0000:00:12.0 <- ?

It *looks* like there is no *failure* (as in here ), but I am not sure it actually suspended and woke up, or it exited suspend (if they are two different things). $ journalctl -b | grep -nH suspend (standard input):1576:abr 06 07:28:55 Orion sudo: root : TTY=unknown ; PWD=/home/santiago ; USER=root ; COMMAND=/usr/sbin/pm-suspend (standard input):1578:abr 06 07:28:58 Orion kernel: PM: suspend entry (deep) (standard input):1583:abr 06 07:29:04 Orion kernel: printk: Suspending console(s) (use no_console_suspend to debug) (standard input):1627:abr 06 07:29:04 Orion kernel: PM: suspend exit Adding possibly useful lines.
