Where did my green battery icon pic on taskbar go??

[jhk]

Hey everyone.. new thinkpad T60p owner. I noticed today my little sideways green battery icon on the taskbar has disappeared.. and i can't find a way to get it back. It is probably something simple, but don't know why it has disappeared. The only thing I have done is the basic new update/install for windows xp from the bottom right corner of the taskbar when it became yellow.. stating i had update to install. I really like the green battery thing.. pls help. Thanks,
Jae

Click Fn+F3, then "Manage Settings" and then "Options"

Check the option to "Show power manager guage in task bar."
