After upgrading from 23.04 to 23.10, my laptop can't sleep: when trying to sleep, it immediately wakes up again. This occurs when no peripherals (Bluetooth anything, keyboard, monitor etc.) are connected too.
I have tried toggling "wakeup devices" in /proc/acpi/wakeup as in Ubuntu wakes up after few seconds of sleep, but disabling them all didn't prevent the computer waking up immediately.
Any help greatly appreciated!
