Windows 10

I did that with my Dell battery many years ago. Do not know of any third party software. I can only suggest to keep an eye on Lenovo website and get in touch with support to get info if an update is coming.
 
Or that I got him Apple's new OS

On a serious note, it accepted the Win 8 license & has started the installation process..
 
the latest power management works but the only problem is that its one feature of restricting the charge once battery percentage reaches 50 % was not working.
In my laptop one file was created when reset was performed and from there i got the version of power management i was using before.
Visited the lenovo support and luckily got that old version software.
The old version of power management also has this feature and its working .
Thats what i need :D
finally a relief :D
