Last year, I got a Microsoft Surface table for tasks like marking up PDFs and articles with hand notations. By doing this on a tablet, rather than paper, I've got a permanent hard drive and cloud record of my notes.
In the last month or two, my Surface became almost useless by CONSTANTLY going into hibernation mode at 1 to 5 minute intervals. Numerous web articles talk about random "sleep" mode in Surface tablets.
A website called "LoveMySurface" provides an article how to very quickly and easily disable the Hibernate mode in a Surface tablet.

From the SEARCH field, type the word COMMAND
You'll see the COMMAND app, and one offered option will be "Run as Administrator." Unless you're computer has been instructed otherwise, this requires nothing more than tapping that entry.
You'll see a prompt, C:\Windows\system32>
Type
powercfg -h off
and then hit Return.
See the link above for full details. I just did this today, and it seems to have solved a really bad problem.
