Windows 7 Laptop Sleeping issues

[t3dw4rd0]

I recently upgraded from Vista to Windows 7 (64 bit) on my Acer 4810T-8480. One problem I've been noticing frequently is that when I tell the computer to sleep or even just close the laptop lid, the screen will go black, but the power light will stay on, as opposed to blinking orange as it used to with Vista. Does anyone know how to solve this? I should be able to provide any other necessary specs.

EDIT: Solved, the wifi card in my laptop was waking my computer up continuously so it would not power off. I just had to change the settings in device manager.
