My microsoft surface will not turn back on at all and I had many memories on there?

IF I PURCHASE A NEW SURFACE CAN I SIGN INTO MY MICROSOFT ACCOUNT AND STILL HAVE All MY PICTURES AND DOWNLOADS! Like if you break an iphone and buy a new one you can log into your Apple ID and have everything you had on the other phone I need to know If I can do that with my microsoft surface

IF you have saved things into the Microsoft cloud (OneDrive), then no problems.
If you have saved things locally onto your laptop / tablet, then they will be gone.

Have you tried holding the power button in while counting to at least 15 seconds. Then release, wait for 10 seconds. Then press power for 1 second?
