Set Phoenix BIOS watchdog timer to 0 to work in Fedora

I noted on that on Acer Extensa legacy-BIOS laptop, one has to set

all watchdog timers to a value of 0 (= zero )

else the laptop will reboot instead of properly resuming from sleep-mode.

Probably those timers are meant to work with Windows only, like the Acer Recovery F12 functionality.
