Sorry if this topic has already been discussed. After much searching for my exact problem I wanted to see if any of you guys could shed some light on my situation.... So I bought the 15" Alum Pro model before they came out with the newer Unibody. Up until now it's been the best thing that ever happened to me. My problem is about 3-4 times during the workday the keyboard and trackpad both freeze causing me to manually power down. After it happened about 5 times, I decided to spend two hours on the phone with Applecare. Long story short...they had me check the ram and do a diagnostics on the hard drive ( I guess the equivalent to disk defrag?) Taking the battery out and going through a bunch of processes that all came back fine and after all that the problem persists. I've searched all over and see that other people have had this problem but there hasn't been one concrete option for me to try. I've tried a firmware update for the trackpad with no success because the computer tells me I don't need that update. It is the Model Name: MacBook Pro Model Identifier: MacBookPro4,1 2.4 GHz Intel Core 2 Duo Processor/ 4 GB 667u MHz DDR2 Ram. Something to note. The problem seems to happen right after the computer goes into Hibernate mode ( battery saver screen ). Sorry not sure what that mode is called. Sorry for the long post and thanks in advance for any help. It is greatly appreciated.
