I did extensive research and cannot find a solution that seems to work. My new MacBook pro runs Mountain Lion 10.8.2. Whenever I reboot it in the morning, or when its been sleeping for some time the keyboard and trackpack misses the first letters or takes about 5 seconds to register - to actually start working. This is NOT a Retina = therefore I don't think the Power Nap fix will work like on the Retina...... Please if anyone can assist it will be greatly appreciated.
