Charge 3 won’t turn on, charge, or restart

[Jackball]

I stopped using my Fitbit for about 2 months (sitting on the couch, not much to track) and decided to charge it back up to start using again. I plugged it in and got a short vibration, but the screen stayed black. After a couple hours charging, I noticed it would still not turn on. The only response I can get is squeezing the side, which causes it to vibrate for as long as I am squeezing it. I’ve tried the 8-second and 15-second restart to no avail. The screen never comes back on and I can’t connect to it. Any help would be appreciated!

Hello there @Jackball, welcome to the Community Forums. Thanks for the details provided in your post about your Charge 3's behavior and for taking the time to troubleshoot it prior to posting here. 

As per the description of your post it seems that the battery on your watch may not be charging properly and therefore does not turn on. I recommend that you follow these steps (or please confirm that you've followed them as described below):

• Clean the charging contacts on the back of your device and the pins on your charging cable using the instructions in How do I clean my Fitbit device?
• If the error "insufficient power source" appears on your device's screen, remove other devices plugged in to your power source, or plug your device in to another source.
• Try a different USB port or a UL-certified wall charger.
• Check the alignment and try reconnecting your device to the charging cable. For more information, see How do I charge my Fitbit device?
• Restart your Fitbit once again. For more information, see How do I restart my Fitbit device?
