Got surface pro 4 having intel core i5 processor. Once it goes to sleep mode, the screen wont turn up and also the battery starts to drain fast making my surface pro to a heater. Took my surface pro to service centre and they told me that the issue is with processor and an update is coming soon. So until then they suggested me to shut down my machine rather than turning the thing to sleep mode. This is really frustrating that every time I need to make sure that my surface is shut down properly.
