Hello, Abby Calimlim.
Welcome to Microsoft Community!
Thank you for your description of the incident and I understand your concern at this time.
I am sure you have tried the possible troubleshooting suggestions:
Fix problems with charging Surface Slim Pen - Microsoft Support
Obtaining repair services is obviously a more appropriate and effective option at this point. Prompting that the warranty has expired is clearly a false phenomenon.
I will share with you here the common steps in the community to create a service order, and we can reach out to the Surface technical support team and get the details of the repair through the following:
Open the Surface App (usually built into your Surface device, or you can download it from the Microsoft Store if you don't have one) and follow the procedure below:
- Click "Help and Support" and then click "Get Help".
- Briefly describe your problem in the text box, such as "Surface Slim Pen won't Charge", and then press Enter.
- Click "Contact Support" at the bottom.
- Select "Technical Support" > "Surface Accessories" and click "Confirm".
- You will see "Chat support" and "Phone support" options, please contact them during working hours, you will get one-to-one support services.
Note: When using the Surface App, please sign in with your current device's Microsoft account.
I hope your hardware issue will be handled properly.
Best Regards.
