Windows 10: I can't open my laptop

After logging in into Microsoft account, I accidentally press the power button and when I try to open, it stuck in lock in screen. When I click the sign in it will just go back to the lock scree. What should I do to resolve this problem

Laptop with broken screen How much?

I would like suggestions and look in local stores. I dont wanna buy a laptop from someone online. Sorry. But could be a good idea if you asked him about the performance on older games. Gonna make a list ofall laptops people suggest me.

Remove the screen for space purpose here its small desk and if the screen is opened it will hide my 22 inches lcd

 

Best laptop under $800??

Well the last one I suggested seems to be the best for 650$
