Display Tray

How can I change windows 7 battery display?
I have a windows 7 laptop and it shows the battery in the system tray (as usual), but when i hover the cursor over it, i only get the percentage of charge. Is there a way I can get it to show the TIME remaining and not just the percent? first answer that works will be marked as best.
By default it should show the percentage remaining and time left like mine. What you can do is click on the battery icon, it’ll show you some more info and hopefully the time left. Im running Windows 7 on mine and when i hover onto it, it shows the %age and time left.
