Same symptoms with my Kindle Touch after a fall face-down -- unresponsive Power/Lock button; kinda "slow" response to the Menu button; can charge, can connect to PC and then usable until it locks the screen.

Here's the fix that actually makes sense without need for disassembly: charge the battery, connect to PC just so it allows entering the Kindle's main menu. From the menu choose Restart (not Reset, just Restart). While the Kindle is booting (the progress bar appears), keep ***repeatedly pressing*** the Power button until it completes booting/initializing. Once you see the Main screen, the power button should work as usual (short press - Lock, long press - On/Off).

My understanding is that the fall may have led to intermittent disconnection of some connector, which changed or corrupted the internal hardware configuration, which persists across the reboots. So pressing the Power button during the boot/initialization refreshes the corrupted configuration, reenabling the buttons function. That's just a guess, of course.
