Whenever my Mac goes to sleep when its on battery, it straight away saves its contents to the hard drive and powers off, going into a deep sleep.
This gets really annoying when I walk away for 10 minutes to make a coffee for example and come back to have to wait up to a minute (depending on what I'm running) for the laptop to wake up. This only happens when its on battery though.
I have tried an SMC and cleared the PRAM/NVRAM but it hasn't seemed to work.
Admittedly the other day I was using a terminal command to disable hibernation when plugged into a power supply and must have mucked it up then. I don't seem to remember the command that I used and therefore can't use it to reverse it.
But yeah would there be a way to stop my laptop from hibernating the second it goes to sleep on battery power?
