[QUOTE="Randy B. Singer, post: 1185302, member: 190607"] When a Mac desktop is spontaneously shutting down without an error message, the first thing that I suspect is a bad power supply. When a Mac laptop is shutting down without an error message, the first thing that I suspect is a bad battery and/or energy-saving circuit. You may want to download this program and see what it has to say about the health of your battery/energy-saving circuit: coconutBattery (free, donations accepted) [url=http://www.coconut-flavour.com/coconutbattery/]coconutBattery 2.7 - by coconut-flavour.com[/url] You may want to try re-calibrating your energy-saving circuitry: [url=http://support.apple.com/kb/HT1490]Apple Portables: Calibrating your computer's battery for best performance[/url] ___________________________________________ Randy B.
