Hey jenniferndyer,
Welcome to the Apple Support Communities! Thanks for your question about your Apple Watch not powering on as expected. I'd be glad to see how I can help.
From what you mentioned, it sounds like you've run through most of the steps in If your Apple Watch won't charge or it won't turn on, which is a great resource for when your Apple Watch has power or charging issues.
Is your charging cable the one that came with your Apple Watch, or are you using a third-party cable or charging station? If possible, we want to make sure we're using the cable that came with your Apple Watch, and you might need to let it sit on the charger for several minutes before it powers back on.
If the Apple Watch is totally out of power, and it isn't reacting to force restarts or to the charging cable, you may want to get it inspected. You can learn more about that in Apple Watch Service and Repair.
Thanks for your question and have a great day!
