The cracking sound is not limited to the Surface Pro 4. I have a Microsoft Surface with the exact same issues. Luckily, I caught the popping noise this afternoon and captured the events. Below is a complete list of Errors, Warnings, and Information from
the Event Viewer -- in sequence. These were the ONLY events in the previous hour and occurred right at the time of the "pop."
At the time, the Microsoft Surface was simply sitting on the coffee table (unplugged) with the cover closed.
MICROSOFT … this is consistent with all of the other posts. Please use this information to come up with a fix.
This is clearly an issue with how Windows 10 power management and/or voice activation interacts with the Surface hardware. Please do not instruct me to run diagnostics, as it's not going to show any issues (as has been evidenced by numerous other posters).
Report back here when you've identified the issue and have an ETR on a fix (Win10, drivers, etc.).
Thank you for your help.
