Hello Alison Johnson,
Welcome to Microsoft Community.
According to your description, your Surface Laptop go 2 will run out of power within two hours at 100% charge, so may I understand that you want to find some ways to extend the battery life as much as possible?
Please refer to the following support links for information on how to do this:
Maximize your Surface battery life - Microsoft Support
This is my most direct advice, but if you're unhappy with the battery life of the Surface laptop Go 2, since it's less than a week old, you might want to negotiate a return or exchange.
- If the device is from the official Microsoft Store, then you can follow the support link below to try to get a refund. Returning items you bought from Microsoft for exchange or refund - Microsoft Support
- If the device is from a third-party seller, contact the seller directly.
Best Regards,
Mitchell | Microsoft Community Support Specialist
