Is there a utility for windows 7 which will give me the time remaining until my laptop battery is fully charged. GNOME power manager has this functionality, So i was wondering if there is a counterpart for windows 7
There are lots of utilities that claim to do that.
BatteryBar is the one I've using lately, and I'm very happy with it!
It uses what they call "Statistical Time Prediction". This is how it looks like when the battery is charging:
Basically, the OS shows all the information available to it. The "time Left to Charge" parameter is dependent on the hardware you're using and its manufacturer. If your laptop's manufacturer provides a power driver, I suggest installing it.
Case in point: I have 2 laptops, a Lenovo T400 and a Dell Mini 9. Both have Windows 7 installed. On the Dell, all I can see is "xx% remaining". On the T400 I also get time left to charge, and i can actually configure (through the Lenovo Power Manager applet) what will be shown when the laptop is charging and when.
I recommend visiting the manufacturer's site and looking for the appropriate driver.
