@torture Thank you .The strange fact is I don't need to power on NLBA .It can read the bat info.But NLBA1 output led not on.
Can someone assist me to unlock this battery Dell PC764?
NLBA1 can read the clock & data But charge and discharge terminated.
Post a picture of the chip and the fuse.
Having in view Manufacture Name is Panasonic, chip is likely max1781 there.
