Q: Macbook Pro Late 2013 battery drained when in sleep mode

I'm having the same problem of battery drain for quite some time now.

I tried to use the terminal commands suggested by saildiverdog and got the following output:

Total Sleep/Wakes since boot:17

Idle sleep preventers: IODisplayWrangler

So it seems this IODisplayWrangler app is preventing my laptop from sleeping properly.

I tried to google it but couldn't really find any indication of what it is or how to solve it.

If anyone can think of something that would be great..

Thanks!

My battery drain problem was caused by Norton Internet Security. I uninstalled Norton and things were back to normal. Here is more details on what I did.
