I needed a new charger as my original one became faulty and kept losing its connection to my laptop. I was relieved to have a new charger so that my PC would stop beeping every time its connector moved. So for that reason, it gets 3 stars. It loses 2, as the cable is a little bit too short in comparison to the original cable, and this means that it often disconnects midway where the adaptor box links the two cables. Otherwise, a decent replacement for old.
