Hi RaniaRimali,
Thanks for reaching out to Microsoft Community and posting your inquiry.
The device could be hibernating and needs to wake up. We suggest the methods below:
• Press the Windows logo key + Ctrl + Shift + B. This restarts the graphics display driver. If the device was stuck on a black screen, this may resolve the issue.
• Force the device to restart. Press and hold the power button until the logo screen appears (about 20 seconds).
If this answers your question, we highly encourage you to inform our Community by clicking on Yes or marking my post as an answer. This will help other members who may have the same issue as you. Otherwise, don't hesitate to update us so we can further assist you.
