Hello Mustafa HasanHE,
Thanks for reaching out to Microsoft Community. I understand how alarming it is to see the battery on your device that has been swollen.
In this case, battery expansion from deterioration does not present a safety concern and is most often caused by the formation of non-flammable carbon dioxide (CO2) gas. If you have a device where the battery has expanded visibly beyond the mechanical enclosure, we recommend you stop using the device. You should handle the device with caution to prevent putting pressure on or risk puncturing the battery cell.
With that being said, this particular issue is best handled by our Microsoft assisted support. You can contact our support via Contact Us Microsoft Support to seek options for your device and real-time assistance. You can also contact them at Global Customer Service phone numbers (microsoft.com) underFor Business users. This also works with Home users, just select Surfacethen Homeas a type of user in the IVR prompt.
Best regards,
StevenK
