Is there a way to know the battery level of your wireless battery-operated keyboard and mouse?

@DAFRIAS -- I have a "multimeter" that I use in many ways, including testing those batteries.

Check both the VOLTAGE and the AMPERAGE output.

The chemistry inside the battery produces the VOLTAGE, but it is the simultaneous chemistry that produces the AMPERAGE.

 

Compare to one person trying to push an automobile, to adding 5 more people, each with the same strength as the first, to push 6 times as hard -- that is the AMPERAGE at work, to move the automobile.

Maybe the better question I need to ask is: "Is there an app the checks battery level on wireless keyboard and mouse"?

 

Also can HP come up with software for adjusting on board camera from wide angle to narrow angle and zoom in and out? The apps out there have advertisement and smileys and I don't like how they work.

Yes, HP could. But, would consumers buy such software?

 

In the world of stand-alone cameras (optical or digital), there are just two types of "zoom".

Either you have a lens on the camera that adjusts telescopically, to deliver full-resolution images into the camera's recording surface (digital or old-style film), or you have software that just "snips" the incoming image, reducing the resolution.

In your case, would it be OK to capture a still image, and use software to "crop" it to save the only the selected area?
