Express just quit

I’ve been using my Express, no problem, but I plugged it into my computer to recharge, left it overnight, and now it won’t start up…nada, zilch…just won’t power up? Any suggestions? I know on my 280 I can press on button and record button with the lock on and it powers up, but is there a similar fix with the express?

same with mine. it doesn’t turn on anymore after an over night charge
