Hacking How does the DS know when it's been closed?

[Steevsee]

Just playing around with my DS and got to thinking about this.

When you close the DS, the screens turn off and it goes into standby mode or whatever, to save battery, blah, blah.

But how does the Ds know that its been closed?

There's no obvious switches anywhere near the hinge, but once you close it far enough, the screens turn off. How?

Very mysterious! or am I missing something simple?

it has a !@#$% magnet. lol. have you tried it with a magnet and wave it at the back of the top screen? The magnets are besides the touchscreen. not sure

actually there is a magnet in each of the speakers.there is a sensor between the a,b,x, and y buttons (probably hall effect) which activates sleep mode when brought near a magnetic field.
