“ This is a HARDWARE problem! After playing around with removing the battery and noticing that this often returned functionality to the keyboard I surmised that this had some sort of physical aspect.
Sure enough, there is a section of copper colored tape/wiring exposed in the batter slot that is slightly bowed where it’s smallest.
When I depressed this with my finger tip on this portion to basically flatten it out flush against the housing; I found that all functionality was restored! Apple - Support - Discussions - Unresponsive Keyboard and Trackpad …. This just happened to me last night. Given all the software problems that there have been with MacBook Pro keyboards under Leopard, it was hard to track down this information on hardware problems with the keyboard. Sigh. I’m starting to regret not sticking to my guns regarding Apple hardware. Since there’s no way to run OS X on non-Apple hardware, I guess that since my next laptop will not be Apple hardware it will also not run Apple software. Sigh. I miss running Linux on my desktop anyway. Compatibility with Adobe Creative Suite, Lightoom, and MS Office just aren’t worth the frequent disruption I suffer on this platform. Perhaps I’ll buy a “real” computer for doing “real” work, and will keep a shiny one on the side of my desk for the occasional need to run the shiny softwares.
