Handheld vacuum (not working) (South Salem)

Shark handheld vacuum purchased in May 2020 (retails now for around $100). Worked great until recently when the machine stopped taking a charge. Assume it’s either the battery or the charging dock, both of which could be replaced, but don’t have the time or patience right now to troubleshoot it. If someone else does, I would love to give it a second chance at life!
