This is so hard without being able to root the device.
Backing up, when you say it is kept awake, do you mean that it won't go into Deep Sleep, or the screen is actually staying on?
Assuming it's not a screen timeout issue, the places I looked were in the settings battery section - it shows what procs are using up the battery. I also checked settings for applications under running, looking at who was accumulating CPU, and also the System Panel app, which gives a different view into processes running.
What I would recommend is to charge the tablet up, then right before turning in, restart it (which will reset all the usage counters) and leave it that way overnight. Check first thing in the morning for what has been happening during the time it should have been in Deep Sleep.
