Battery Power draining even when PC is Off?

    Hi,
    I am just clueless about this. I turned my computer off with the battery at 100% ( I was using power cord
    with outlet). I disconnected from the server at the coffee shop, went to " Shut Down" on Windows icon menu, turned machne off. This morning I turn my PC on and the battery is at around 2%. I've had this happen ( at different levels) a few times. What is going on?

    It can be like sleep sate not shutdown. This was implemented in windows 8.

    Can you remove the battery? Isolate the variables. Shut it down with the battery fully charged, then remove the battery. Leave it over night. Put the battery back in and turn it on. Did it drain again? If so, then it's the battery and needs to be replaced. If not, then Windows prevented shutting down for some reason and you can check your event logger for why. If you still can't figure it out, dual boot Linux, then shut down from Linux. If it still drains, then it wasn't windows, it was your computer itself. Something is shorting out.

    The new state in Windows 8 was kernel hibernation, but the system still fully powers off. My guess is you closed the lid before it completed the shutdown process, and was in a standard sleep state.

    Good point. I remember seeing some lights inside after shutting down the machine.

    Good idea, scientific method, except too much going on; trying to see if someone already did it and get it out of the way, use scientific method when I have more time.

    I had a problem like this once. Pressing the power button would send it into hibernate. If you immediately closed the lid the computer would sleep in the middle of the hibernate and just run full power until you opened it up again. Then it would actually finish the hibernate.
