Battery management laptop software?

[jaydee]

Does anyone know of Windows software that will manage the battery charge/discharge state? When it's plugged in, I'd like the battery to charge to about 75% and stop charging. When it gets down to about 50%, charge it back up again to 75%. Of course, also have a setting that will charge it all the way to 100% on demand for longer trips away from the power outlet.

Does this exist? I've looked around and I found a proprietary programs that work on Lenovo and Samsung laptops, but that's it.

I was also interested of something like this for an Asus but I coudnt find it.Apparently HP laptops have a software for battery management.

Bump... Does anyone know of any software that does this? Only Dell seems to have it for their laptops. I don't think it should be that hard to code, why is there no third party software that can control charge? Windows already suspends charging at 100% until the battery has discharged to 95% or something... So why don't we have software that can stop it at a set percentage and start it again?
I've been doing some reading at Battery University and it seems that the best zone to stay in for batteries is 65-75%. That's it, all of 10% to play in for best longevity...

Such software capability is available in my Lenovo T420 (uses native WIN7 OS).

You might go out to the Lenovo website, download the power management application and try to install it to see what happens. A guess though is that the BIOS needs to also support such power management for such app to work.

Because it's not a small thing to code. Windows does not do suspend charging. Windows can be configured to respond to certain battery percentages (throttling, shutdown, sleeping, etc) but Windows by default does not have any tie-in into the the Battery Management System. That is purely tied to the laptop's Battery Management hardware and requisite firmware that controls it.

As you mentioned, some laptop manufacturers build software that interacts with their laptop's battery management hardware (Lenovo, Dell, etc) but those are proprietary pieces of software specifically written to interface with their battery management hardware.

Several battery management systems have absolutely no configuration ability. Their parameters are burned into the firmware and set in stone. It is very much a case-by-case basis. If your laptop manufacturer does not have a software tool to interact with their battery management system, then you're not going to readily be able to selectively control it.
