I bought my Mac Book Pro 4 years and 3 months ago.  Recently, (last 6 months) it has been
restarting by itself about  2 -3 times /day. I have read many posts from people
having a very similar issue but no solutions. Any ideas?

First.......... check for any firmware update - hope this provides a solution to your problem.

which model do you have?
The power supply could be on it's way out...
try using the laptop on power alone, with the battery removed and see if this affects anything.
Do you have much battery capacity without power cord plugged in?

roylong:  Version 1.1

Also reads battery remaining incorrectly at 99%. Says 4:22 - However, at 50 % =  40 minutes.

Why would removing the battery affect anything?
BTW - Problem usually occurs when plugged into a second monitor. Thanks

It appears that the restart issue occurs when I have my MacBook Pro plugged into a 2nd monitor.
Any ideas?
