Chosen Solution
I have a flip mino HD that refuses to turn on. The lights light up, and the screen sometimes displays a low battery icon. It looks fully working but won’t charge!
@mr35 start by repalcing the battery. It is absolutely conceivable that it is discharged below it’s threshold. Replacing the battery will providwe you with a known-good starting point should further troubleshooting be necessary Flip MinoHD Battery Replacement
These cameras have a major design flaw. The battery charging control circuit is powered by the battery instead of the USB input power. Once the battery voltage falls below 2.8V the battery charging IC will never turn on again, even with the charger plugged in. The only way to recover is to physically remove the battery from the camera and manually charge it before reinstalling it. If you are using your camera regularly most likely you wont see this issue. If camera is left with discharged battery for a long time (where battery voltage falls below 2.8v) it will pretty much become useless unless you know how to take the battery out, manually charge the battery above 3.3V and reinstall it. If you ask me CISCO got really screwed by buying “pure digital”, the company who made this camera.
This happened to me after not using the camera for YEARS. I left it plugged in for a day or so and it worked like a charm. Which is a good thing because I’m no good with the dismantling business
