The details vary, but after I wake up my laptop running Windows 8.1 preview, something is always wrong. Just now, I could move the mouse cursor but could not do anything with it; I finally had to remove the battery to shut the computer off, allowing a restart, after which everything was fine. On two other occasions, the computer apparently did not go to sleep as the battery was drained.
I'm running Visual Studio [administrator mode] and MySQL workbench a lot, as well as Chrome.
How can I fix this, so that it goes to sleep and wakes up normally?
