Charge 5 blank screen, unresponsive

[M.S.111]

Advice says to hold button on side down to reboot however there is no button on the side.  Tried unplugging and plugging back in advice as well, which has done nothing.  Selecting advice from Support Team just takes you round in circles stating to hold button down.  I would like a response from a real person please who understands that there is no button available so need another option please.  No lights appear on back of device and does not vibrate when plugging in indicating that it is on charge.  I keep it clean, so that is not the issue.  I've also not gotten it overly wet.  It also shows on the phone that it has not synced for several hours, with last battery percentage showing at 69%.  Was fine when I went to bed, blank screen and unresponsive since I got up and no sleep data recorded.  Any advice would be gratefully received.  Thanks.

Hello @M.S.111!  It’s nice to see you around!

I'm sorry to hear that your Charge 5 is not working. I appreciate the information provided. 

In the case of the Fitbit Charge 5, the reset button is located at the end of the charging cable, on the side that connects to the computer or wall outlet. You need to confirm that you have cleaned the charging pins on the watch and the charging cable as requested in the article:  How do I clean my Fitbit device?

Once you have cleaned the charging contacts, please perform a reset as follows:

1. Connect your Fitbit device to the charger.
2. Please remove and re-insert it quickly.
3. After a half-second pause, repeat this removal and insertion motion 3 more times, all within a span of 8 seconds.

Once the contacts are clean and the reset is done, please connect it to the charging cable on a computer or to the wall with a UL certificate adapter and leave it for a few minutes to check if it charges and reacts.
