I have my lenovo x230 laptop set to sleep when I close the lid. When I close the lid the "sleep" icon on the back of the screen lights up. But the batter will not last through the night on sleep mode. Within five hours or so, the battery is completely drained and I have to plug in and boot up the system. I've never seen such poor batter performance during sleep mode on any other laptop I've ever owned.
Another thread in this forum blames the USB port that allows you to charge mobile phones/etc. during low-power states and recommends disabling the "always power on" option fo this USB port in the Bios settings. I've done so, be it doesn't seem to have helped. At least my laptop still will not make it through the night in sleep mode.
At this point, it seems my ownly option is to use sleep mode only when the laptop is plugged in and hibernation mode when on batter power, which is disappointing. I've never had to worry about this in the past with other laptops.
Perhaps/probably related is the fact that the lenovo ThinkVantage Power Manager (v. 7.16) hangs at the splash screen when I try to open it, so I've been trying to manage the power through the windows control panel power settings.

Use powercfg tool from within cmd window (run it with right of Administrator) to check power efficiency.
powercfg -devicequery wake_armed
Thank you so much, this was perfect. I noticed my laptop wasn't sleeping and giving me other issues. After running these can commands I realized I had just paired a bluetooth mouse a few days ago when all the issues started. Sure enough, it was set for wake-on and as soon as i disabled that, all was back to normal.
