HP nx7300 won't standby or hibernate when closed

hello,

i recently had to do fresh install of xp pro sp2 on my nx7300 laptop.
since i have reinstalled the os, every time i close my laptop lid, it
only turns off the screen and does not hibernate or standby. in the
power options, advanced, when i close the lid of my portable computer,
my only options is "do nothing" there is no option to hibernate or
standby. i ran all win updates and installed the hp quick launch
buttons and touchpad. there are no device issues in device manager.

can someone let me know how to get the options to "hibernate or
standby" when i close my LT lid?

thanks
.
