Several times now I’ve experienced the following issue. After normal use, and plugging in the reform while it is off, if I try to turn it on it is completely unresponsive – no LCD, no LPC wake-up indication, nothing. Normally I have to hit circle a few times to get the LPC to come to life, but now nothing happens. Strange thing is, if I open the case, unhook power from the board, take out the batteries, put them back in, then reconnect power to the board, everything will come back to life just fine. And the batteries will work well and seem to be at the correct voltage.
(I have the updated keyboard and LPC firmware installed)
