Powers down while starting
My MacBook Pro will power down at anytime.
99% of the time it powers down while it is still starting up and before fully loading the OS. It doesn’t matter if it is plugged in or not.
The 1% I do get it startup and get to a web page as soon as I change pages of move to a different site it shuts down and restarts.
I bought a new battery worked for about 2 weeks then started doing it again. Then I changed the 330µF 2.5V Aluminum Polymer Capacitor.
Neither alteration helped. Any suggestions?
I found a way to get the computer to boot and get into the internet - I reset the NVRAM (PRAM) If I do to much at once it will shut down then I just restart it, If I only play poker (gaming) its OK, If I do that and go into the internet the computer shuts down. Then I just restart pushing the option - command -P - R at the same time for about 3 to 4 seconds until it makes the start up sound everything works for awhile. Still shuts down if doing to much or if I just let the computer set idle for a few seconds 7 to 8.
I am thinking the Polymer Capacitor is either faulty or installed incorrectly.
Thanks Stephen your answer helped it powers down a lot less. Now when the computer goes to sleep or I put it to sleep, and if I try to go into Netflix or another movie site it will shut down, but works great just in the web. A lot better then it was a few days ago. When I run the gfxCardStatus then things seem to work O.K. for awhile with movies & Netflix.
Ist dies eine gute Frage?
