@Danielle13,
 
Welcome to the HP Support Community!
 
I assure you I will try my best to get this sorted.
 
In order that I may provide you with an accurate solution, I will need a few more details.

When was the last time the battery was getting charged?
Have you checked with a different charger/Data cable?
Have you performed any troubleshooting steps before posting?

While you respond to that, I recommend you update the sprocket firmware and check if it helps.
 
Here is how it is done.

Make sure the Sprocket is on and your mobile device is connected to the Internet.

On your mobile device, open the HP sprocket app.

Tap the Menu icon , and then tap sprocket.

Tap Manage Printers, make sure your Sprocket is selected, and then tap Printer Settings.

Look for a firmware upgrade.

If a firmware upgrade displays, tap Get Firmware Upgrade, and then follow the on-screen prompts to complete the update.

If a firmware upgrade option does not display, the firmware is up-to-date.

Let me know how it goes and you have a great day!

Cheers!
