One day in October, m@y old Lenovo IdeaPad 110-15lBR failed to boot up. After checking the charger connections, I noticed there were no power lights lit up anywhere. I took a chance on this exact replacement charger, but still no power lights. I disassembled the case & ordered an exact replacement battery, which once installed, charged up with this charger & showed power lights lit up...IdeaPad is still useful. Look for my review of the replacement battery next.
