Hi Krishna,Thank you for posting your query on Microsoft Community.I understand your concerns with Windows 10. Put your new battery in your laptop and open as administrator.4. Go into config and change 'Capacitypercent' to 0 (Zero) and then save. Tick 'use as administrator' or whatever you call it and also 'compatible with windows vista' instead of windows 7.3. Close all programs, and right click BIOS Update and then properties. Or 'Not compatible with Windows 7!' Or 'Battery is under 30%' and will not let you go any futher. Open the BIOS Update and you'll notice that it'll say 'Your battery isn't included.' Sony Bios Update Windows 7 Sony Vaio Bios Update Windows 7 64 Bit (The reason for this is because I can't use discs at the moment so ignore this one)2. Open the BIOS Update disc that is included with the new battery on a different computer, transferring the files to USB stick and putting them on my laptop. I also found that many people had the 'Your battery is plugged in, but it's not charging' problem, but none of the solutions worked for me. That didn't phase me as I like to prove myself right. Little did I realise, my new battery wouldn't charge as I needed to install the discs and update the BIOS but for that you needed 30% battery or more, not even plugging it in would do it.Īfter looking endlessly over the internet I realised that the battery I had bought was not compatible with windows 7 and the seller even explained in bold letters 'DO NOT BUY IF YOU HAVE WINDOWS 7 AS IT WILL NOT WORK'. My SONY VAIO VGN-CR21S/W is a beauty.I received my battery 24 hours before my charger so by the time my charger came, my battery was dead, oops.

Ash0770 here!Hi everyone, after my battery and battery charger dying on me I decided to buy a new charger and battery.
