my standby button is greyed out after re-installing Windows XP

my standby button is greyed out after re-installing Windows XP: "

Hello,



My hard drive crashed last weekend so I put in a new one this week. Then I re-installed Windows XP and all the drivers. Everything seems to be working except my standby button is greyed out and I can't standby or hibernate. In the power options screen, there's no hibernation tab.



I tried re-installing the video driver, chipset drivers, etc., but that didn't help. Any ideas?? :confused:



My computer is a Dell Inspiron 600m laptop.





thanks for any help! :)
