Battery discharging even when plugged in

I have a t400 and my battery (9cell) is discharging even when the laptop is plugged in.
BIOS is verified, so when it is shutdown it won't consume useless power (lan, usb, etc).
Even if the laptop is plugged, when _shutdown_, it still consumes power from battery. Apparently it also happens if it is _on_.

Power manager is on "always fully charge". It was also set on "optimise battery". 

The power consumption is not much but is decreasing by 1% every 1 - 1.5 days.

Is this normal ? How can I fix it ?

Re: Battery discharging even when plugged in

hey amb00,

curious to know when the power supply is plugged in, you did say that the battery is discharging. What's the rate of consumption?

And while you check on that do check the following link

Re: Battery discharging even when plugged in

My T400 battery discharges a bit over a few days too. Seems normal. I think it goes down faster the more I game.
