my macbook pro suddenly shuts down
Hello everyone,
I am having problems with my MacBook Pro.
It suddenly shuts down without any warning. I tried turning it on, a few seconds after the sound, it would shut down.
I read the User Manual and tried a command "press Power Button, and immediately hold down Command Option, P and R Keys simultaneously" and my laptop turns on. Sometimes it would still suddenly shuts down.
I also noticed that the mouse sometimes isn't as responsive as it used to, very slow.
I also downloaded iBoost to see if it helps.
Hope to hear from you.
Thanks.
MacBook Pro, Mac OS X (10.6.8)
