MB sleeps when power removed?

I noticed something just now, and looked at the energy saver settings, and cannot figure out why my MB does this. I run it closed right now, but in a few more weeks I'll be using it alot more away from home.

I noticed that if I pull off the magsafe power adaptor, the computer instantly goes into sleep. I can wake it pretty easily with the remote, but after typing in the password, it "flashes" for less than a second whatever the screen was before it went to sleep, then goes back to sleep. I can repeat this as many times as I want, but the thing won't stay awake until I reconnect the magsafe.

It's set to go to sleep if inactive for 15 minutes, and display sleep is set as the same. Battery meter says it is completely charged and my health is darn near perfect according to Coconut.

What have I done to make it sleep when Magsafe is removed?!?

[edit] with the MB screen open, it does not sleep when magsafe is removed. I'm sure I've got some setting off. Which one, though?

That's how it should be? I don't understand this part. If your screen is open, then your computer should not sleep when you remove the magsafe. If your screen is closed, then your computer should go to sleep. What am I missing here?

From my understanding, the computer is running in clamshell mode. The problem might be that you have no devices attached though... Taking the adaptor out changes the power settings, remember. :)

I am running in clamshell mode.

The problem is, it won't wake up correctly. It seems to, for less than a second, then seems to b esleeping again. It will only "flash" the desktop at me, then goes back to sleep.

I have tonnes of devices attached! KVM swich for monitor, mouse, keyboard. External monitor (obvious, for clamshell mode to work well :) ), speakers, sometimes an external drive or two and an ethernet cable.

As for taking the power adaptor out, changing settings, I have the settings set for it to go to sleep after 15 minutes of inactivity whenrunning off of the battery. Why would it chnage my settings for battery usage when it goes to battery usage?

Sorry for being confusing. I'm saying your computer will notice that the adaptor isn't plugged in and will revert back to your battery settings. Nevertheless, it shouldn't be behaving like this, especially if you have devices connected. Try the SMU reset and see how things go. :)
