Hello Naairah,
Welcome to Microsoft Community.
If the touchpad you are using for the Surface pro 7+ Type Cover is not working properly, I would probably prioritize a driver anomaly as the source of the problem.
Since it is not clear what recovery solutions you have tried, please allow me to share the drivers and firmware packages for Surface Pro 7+ with you first here:
Download Surface Pro 7+ Drivers and Firmware from Official Microsoft Download Center ****
After manually downloading and completing the installation, restart your Surface and verify that the Type Cover touchpad is back to normal.
If the problem persists after reinstalling the drivers, you will have to consider the possibility of hardware failure, so my second recommendation is to send your Type Cover along with the Surface Pro 7+ to the Surface technical support team for inspection or repair. You can contact Surface Live Support through the Surface App:
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 "Type Cover's touchpad doesn't work", and then press Enter.
- Click "Contact Support" at the bottom.
- Select "Technical Support" and click "Confirm".
- You will see "Chat support" or "phone support" options, please contact them during working hours, you will get one-to-one support services.
Considering that the warranty period of this product may have expired, and only as a kind reminder, this service may involve additional charges:
How much does out-of-warranty service cost for your Surface device or accessory? - Microsoft Support
However, if you notice that the price is more expensive and therefore actually plan to buy a new Type Cover, the official sales link is here:
Microsoft Surface Pro Type Cover | Surface Pro Keyboard - Microsoft Store ****
It's just that I noticed that this product is out of stock, perhaps you could contact a sales representative to confirm if there is a replenishment plan:
Alternatively, try going to Amazon to see if a third-party Microsoft authorized reseller still has it in stock.
I hope these suggestions will help you.
