Right so I've been using my D10 every day at work after purchasing it off my mate a few weeks ago. I've been running it as a USB DAC/AMP for my ATH-ES7's and was never sure about leaving the charge switch on the on position or not (while it was connected) so I just left it on thinking it wouldn't charge the battery if it didn't need to (its meant to have overcharge protection) and would simply use the USB input as power too...
However, this week I noticed the red led on the bottom back of the D10 now never turns off - regardless of if I have nothing connected and the volume off, and it seems like the battery now drains quickly while its not in use, as when I turned it on yesterday the light next to the power knob flashed. I tried charging it overnight last night with the volume power switch off and having it only plugged into a USB wall-wart but the bottom red led on the back is still on (but the front red led now doesn't flash). I've opened it up this morning and double checked there are no shorts. Obviously the led turns off if I disconnect the battery :P
Any ideas? Does the red led on the back stay on if the battery is dying? Or have I possibly damaged it while rolling opamps? (I forgot to disconnect the battery while doing it once).
Cheers.
