4015 module explain two leds induction function

Hello there,just wanted to know that I have a dell laptop charger with the output of 19.5voltage which is what it’s showing on the multimeter however, when I plug the wire, it’s not charging onto my laptop. I have also bought a new charger and it’s charges but the old charger doesn’t charge up. I have bought 4 chargers as well but it’s also the same voltage for all for of them in the multi-meter. The needle pin of the charger is not damaged either. If there is a video for this, could you please send me the link to find out what the error is please?
