Power button uses

I am really frustrated by the way the power button behaves. When I put the tablet to sleep I expect power button to wake it up. But I simply can not resume windows. I tried double tap on the screen as well but it did not work. Is there any known issue with the power button? How can I use the power button to just turn on/off the display or to put the tablet to sleep and wake?

Any issue ? I have a same prb

its a dead parrot… have the same question

Same problem, did anyone figure it out?
