I have a Macbook Pro, 13 inch, 2.3 GHz i5 processor running OS X 10.7.3. I self upgraded the RAM to 8GB and the hard drive to 1 TB. I suspect the hard drive upgrade may be to blame. The computer takes FOREVER to wake from sleep. My 2003 Macbook beats it. I'd say it takes about 5 minutes after waking from sleep to be functional. Any thoughts? It seems to run okay after it's been going for awhile.
