My trusty old MX700 is starting to act strangely. Last night, I was going to charge it (which is tricky on a good day thanks to the cradle construction). Anyway, instead of the red flashing led turning green, it just started to flash faster, still in red. Wtf? I tried it a couple of times and the same thing happened each time. I even tried it with the computer off (which should still charge the mouse), but with the same result. So it seems I cannot charge the mouse anymore. Has anyone seen this happen before? I can't find any info on it on the net.
