This is to alert anyone planning to upgrade a MacBook Pro to a possible side-effect and its solution.
I recently put extra memory and a bigger hard disk in a: Model Name: MacBook Pro Model Identifier: MacBookPro3,1 Processor Name: Intel Core 2 Duo Processor Speed: 2.2 GHz seemingly without any problems, but with the wisdom of hindsight I now realise that this Mac stopped giving a start-up sound whenever booted after the upgrade. After about three weeks the machine started intermittently losing its keyboard and touchpad ability. During such events its owner had to resort to an external keyboard and mouse to regain control. I suspected the ribbon cable that connects the keyboard to the motherboard may have been the culprit, because you have to disturb that cable while getting inside a MacBook Pro. So, reopened the machine and re-taped the suspect cable. Curses; stll intermittent loss of keyboard and touchpad. After further head-scratching suddenly thought the problem may be a software one, so reset the PRAM, not expecting much. Voila; the start-up boing is back and no problems for several days. I hope I'm not celebrating prematurely. I relate this in case you have a similar machine and plan to give it a birthday one day. As soon as you have done so, reset the PRAM (hold Command-Option-'P' key-'R'Key combination during startup till you hear at least two startup chimes) to save yourself lots of head-scratching.
