I have L520 (TYPE: 5017-AJ3) and 4 original batteries FRU: 42t4912, 2x 42t4765, 42t4791. I bought the L530 without the battery. However, the batteries from L520 do not work in L530. After install bateriies on L530 laptop they displays a message "The battery installed is not supported by this system and will not harge. Please replace the battery with correct Lenovo battery for this system. Press ESC for continue.
Laptop L530 runs on battery, but it does not charge.
Is it possible to force them to operate?

This has been covered in a few other threads. Lenovo came out with some new RapidCharge thing and the *30 series laptops have it and the *20 do not. The newer batteries work on the previous laptops, but older batteries do not charge on the new line.
