New ThinkPad T520 and need help with hibernate mode

Just purchased a new TP T520 (i7, 8 gb ram, 500 gb disk, docking station) and love it. But when I've used the Windows Hibernate option (Start/Shutdown/Hibernate) and then come back and get the TP out of my bag a few hours later the battery is almost dead. It seems to not really be turning off as I've experianced with other laptops in the past (vs. sleep mode). I've checked all of the power settings and can't find anything that seems to address this. Any suggestions?

 

1. In Power Manager, is Power Plan > Advanced Settings > Hybrid Sleep on or off?

2. In Device Manager, under Power properties for individual devices, make sure that nothing is allowed to wake the computer.

John, thanks for the help.

I started Power Mgr and hybrid sleep is off, but allow wake timers is on. Under Global Power settings enable always on usb was checked.

 

Even hybrid sleep should not almost drain the battery in a few hours.

Have a look at the System Log in Event Viewer and see if anything is waking the computer when it is hibernating.

Great idea to cehck event viewer. I just looked and sure enough when I tried to hibernate it the event log says it was going to sleep, not hibernate. then late last night it looks like the google update service woke up and tried to connect to the web.

 

I also checked the device mgr and the ethernet connection was set to wake up mode and I uncehcked that.

 

Wake timers really suck in notebooks. They should be disabled by default. Otherwise your notebook might wake up in your bag when you are travelling, etc. Not really fun.

My work notebook (not a ThinkPad) did that a couple of times. As its a quad core machine, it starts to warm up pretty quickly when inside a closed bag.
