Computer Does Not Hibernate At Critical Battery Level

I have a Dell Latitude E6410. Via the Windows 7 power options I've indicated that I would like the computer to hibernate when it reaches the critical battery level of 15%. This NEVER happens. Instead my battery just drains down to ZERO and the computer shuts down. Awesome.

Does anyone know why my computer is ignoring the windows settings? Do I have to change some settings in the BIOS? Is something in the Dell Power Manager conflicting with the Windows power manager? Could some other piece of software I am running (NAV) interfere with this?

Any thoughts on how to solve this issue would be GREATLY appreciated.

 

Can you make it hibernate manually?

Absolutely.

 

A long shot. My E6320 came with the DEll power plan as the default. As a result my monitor (when docked) would not use the screen save properly. Changing to the win 7 Balanced profile fixed the issue - it may be worth a try.

Thanks for the idea. Already on balanced.

 

Probably. Dell System Manager and the associated business bloatware seem to the most problematic preloaded software that I've ever encountered. Yes, uninstalling seems to cure the latency and conflict woes. A clean install of Windows might even be a better idea.

 

Is there no downside to uninstalling the Dell Systems/Power manager. Don't I need that to control my keyboard backlighting and screen brightness?

 

What is your setting for Low Battery (it's normally 10%)? If this is lower than Critical Battery then Windows may be confused. I would be!

I have the levels set appropriately, with low higher than critical.

 

I wonder if the system knows when the battery is at some level? Could re-calibrating the battery help?
