MacBook Sleep Issue

[pieterjanprops]

wow, this thread make me realize I may have a problem with my MacBook!

Just to clarify... when I simply shut the lid to my MacBook the light on the right hand side stays solid. I have nothing plugged in except the power cord. Does this mean my MacBook is not really in sleep mode?

When not connected to the powercord, is your battery staying full or nog?

My problem was the EXPRESSCARD

I tried everything and nothing worked. So, I just removed my cardreader ExpressCard, and everything back to normal!!! Expansion cards, like EVDO card, may have drivers that prevent the computer from removing power from them, thus stopping sleep. You'll need to look for updated drivers, or just remove the cards in question.
Sorry for the Portugues.
