Customer Question

OSX Lion version 10.7.3 installed on older MacBook Pro with attached details. It will not sleep or shutdown cleanly. After choosing Sleep from Apple menu, it screen goes dark while the disk remains spinning & the light doesn't turn off. Same behavior when Shutdown is done. After system is restarted with hard reset, problem details are shown as,

"Error 4 trying to transition CPU 1 to OFF"

I done install twice after formatting the hard disk. All sharing is turned off. No printer is installed,so there is no outstanding print queue. "pmset -g assertions" shows EnableIdleSleep as set to 1, all others are 0.

JACUSTOMER-n0l4xg3k- :

No change yet.

JACUSTOMER-n0l4xg3k- :

Do you have any further suggestion ?

CompExpert :

working in apple repairs for almost 10 years, seem to me you got a logic board problem. power issue on your logicboard.
I can help you fixed software problem, but if it a hardware. I recommend that you bring it to apple store to take a look.

basically if you do a fresh installation that removed troubleshooting steps from software to hardware

JACUSTOMER-n0l4xg3k- :

Actually, I think it is a software issue as prior to the upgrade I had SL 10.6.8 which had no problems shutting down or sleeping.

CompExpert :

seem to me like the spec of your computer can handle Lion osx

CompExpert :

what you can do to test it out, what really caused the problem is to reinstall your old osx

CompExpert :

i do have some people after upgrade osx, somehow it damage the machine and problem starting to shown after installed.

CompExpert :

but then when they reinstall old osx

CompExpert :

problem still there

CompExpert :

I dont know what it is, but some few cases, Lion does put a lot of pressure on the hardware and crashed it
