MacBook goes to sleep at random intervals
Hi all, My wife's Mac keeps going to sleep at random intervals
its a MacBook5,1 Mac-F42D89C8
This can happen at any time including :
Regardless of being plugged into the charger or running on battery
If it's writing a CD it will sometimes enter sleep mode
When synchronising with an ipod - it will sometimes enter sleep mode
I've even gone as far as using a spare hard-drive, formatting it and installing EL Capitan on it - after the install had finally finished - I had hoped that the sleep issue would disappear...
Around 10 minutes later - it went into sleep mode again
the only way to wake it would be from pressing the power button and waiting for a response..
