My Macbook Air OsX8.5, after a sleep, often wont wake up and I have to 'Ctrl-Cmd-power' held down for 20 secs to wake it. Then I have to reboot from scratch and it tells me there has been a problem. This is beginning to happen quite often. Why does it do this and is there something I should I do please?
