Hi Tiago!
Thanks for reaching Microsoft Community. We're here to help and let's work on this together.
I understand you're having issues with your Surface device. Happy to help and provide more options here.
To further isolate the issue, please allow us to ask a few questions.
- What version and build of Windows is your Surface device running?
- Which Surface Pro 9 are you using? The intel one or the 5G capable one?
Most common reason for this issue can be caused by a corrupted or outdated operating system. Please follow suggested troubleshooting steps below:
Since performing the Surface Diagnostic toolkit did not help, could you please try to manually update your drivers and firmware. Please see through this link Download drivers and firmware for Surface - Microsoft Support on how to.
After updating your drivers and firmware, please try to force your device to shut down and restart. Press and hold power button for 20seconds, wait for the Windows logo to appear, once it does, release the button and wait for your Surface device to restart.
Please let us know how it goes. We look forward to hearing from you.
Greetings,
RodelioP.
