Wait 1-2 seconds after turning on or wait for the backlight.
Make the contact, wait 1or 2 sec, release and Press F1

Sometimes you may get a fan error which turns off the PC, sometimes you can bypass it by pressing Esc.
other error may occur bad data /uuid /serial etc..this is good sign
just the timming doesn't is not good

The method depends on the Ec (timings are different), it takes several attempts before you succeed and understand.
