I used to have the Logitech solar keyboard and I ran it completely in a building with no windows. It picked up the light from the ceiling tube lights. I ran it until the battery stopped holding a charge and then ordered a new battery from Amazon and replaced it. So the keyboard lasted until I finally left the company and the keyboard was still going strong.

I do not know if the Lenovo works as well, but the solar cells look a little more beefy then the Logitech one, so might get a better charge in low light.

I like the feel of the keyboard (Logitech) and I am now using the MX Keys keyboard, which has a somewhat similar feeling.

I'm wondering this too.


I've used the K780 for about 6 years now for work and its held up quite well. My colleagues use the K750 and find it to work well still.

Now you can charge your keyboard from the sun instead of your computer, think of the minutes of battery power you'll save over the next few years.

It can absorb indoor lights as power. Unless you use it in a dark basement, then you're good to go.

Do you think this would work with a Dell?

The K750 battery is not advertised as user replaceable. You pretty much have to break the battery tray in order to do so. That's my experience. Anyone knows if this Lenovo has an actual user replacable battery?

There are YouTube videos on how to replace the battery. It was simple. But you must find the exact battery that will work. Someone recommended a battery on Amazon and there were comments about replacing the battery successfully in the keyboard. But again, I work in IT, so it was simple for me and YouTube is your friend.

The sun doesn't shine there, is that why it's called the dark continent?
