Does anyone know of a battery optimizer / calibration tool for getting a little more battery life in Win 8.1 on Thinkpad T520? Back when I had Win 7 on this same laptop I had such a thing (drained your battery then recharged it, something like that,) It must have been either native to Win 7 or part of ThinkVantage I guess? I don't care if the tool is third-party, part of Windows, or from Lenovo, just as long as it doesn't require installing ThinkVantage. I don't have TV now and don't want to install it because it's big and bloaty and everything's running flawlessly without it.
I searched for hours and it looks like pretty much all the websites that have info on this kind of thing have dumped their articles that are for Win 7/8 and you can only find Win 10/11 now.
