Hi Ali,
I understand why this is concerning, especially since the Surface was sold as brand-new and the battery report appears to show 99% capacity.
However, the fact that the battery remains at 0% and the Surface shuts down immediately when disconnected from power is more significant than the capacity shown in the report.
Before arranging service, could you confirm whether the light on the Surface Connect charger is solid, flashing, or off? If you have access to a compatible USB-C Power Delivery charger with sufficient wattage, you could also test whether the Surface charges through USB-C.
Because the device was only recently purchased, I would recommend contacting the seller first to request a return or replacement rather than opening the Surface or attempting a battery replacement yourself. If the seller cannot assist, you can register the device and review the available service options through Microsoft device service and repair.
For safety, please stop using the device and disconnect it from power if you notice swelling, unusual heat, odor, or separation around the screen. Thank you so much for your understanding.
