The "e" key on my keyboard is getting really squeaky and driving me insane. I want to pop it off and lubricate it. Do you just pull straight up and it comes off? Someone in another thread suggested going to ifixit or some site like that, but I couldn't find a how-to on any of the MB or PB related sections. Also, does anyone have experience on the long term effects of using the heavier MBP power adapter in a horizontal power outlet? Through a good part of the day I have access to only horizontal outlets, and I'm wondering if this might cause the prongs to break or bend w/ time since the adapter is pretty heavy.
