Hi everyone.
My PC keeps waking itself up from sleep mode, is there any chance someone can take a look at the log and understand the problem ?

P.s. I think I understand the problem: ACPI: EC: EC started - it is a microprocessor that gets signal from keyboard. Turns out my new low-end wireless keyboard sends a signal or checks connection once in a while and wakes up the PC. I powered it off tonight and there was no more awakening.
My PC keeps waking itself up from sleep mode, is there any chance someone can take a look at the log and understand the problem ?
