Acer E380 - Shut off power light when in sleep mode?

Does anyone know of any utilities that would make it so the (extremely bright) blue LED power light won't blink when in sleep mode? Just turn the thing off in sleep mode is what I'd like to do.

I keep my computer in my bedroom. I'd like to be able to put it in sleep mode rather than a full power-off, but the blinking blue drives me nuts! I'm running Windows XP Pro x64 Edition, with 4 gigs of RAM, so apparently Hibernate will not function, or I'd use that instead.
