macbook can not hibernate while connected to external monitor

Question

I have a late 2008 macbook pro unibody 15. I use it with an external monitor. Before upgrading to leopard, I used the widget "deep sleep" to put it into hibernation mode. Now I updated to snow leopard, and when using the external monitor, it does not work, only works without the monitor connected, anybody can help?

This thread on macrumors seems to address the same issue but with Lion:

Can you just use the keyboard shortcut to put it to sleep? The keyboard combo seems to be: "Command + Option then hold Eject"

Does this help? This doesn't use your widget, but it seems quite simple (only takes a couple seconds).

EDIT: I found this link where they turned off the setting to ask for a password on wake-up. It's worth a try...
