Thanks for reaching Microsoft Community.
In this case, please also follow the methods on Surface won’t turn on or wake from sleep (microsoft.com). But if issue still persist, then it's more likely a hardware problem already. Kindly contact our support via Contact Us Microsoft Support to seek exchange options for your device. You can also contact them via phone, see Global Support Phone Numbers.
