curious if anyone knows, but I have a laptop and the adapter quit working. Bought a new one a couple of weeks ago. Well it looks to be going out. I have an adapter from another older laptop and wonder if it might work to charge the battery. The adapter, for laptop in question, is input of 100-240v -2.4A 50/60 Hz with an output of 19v 4.74A. The adapter, i'd like to try, is input of 100-240v 1.8A 50-60Hz with an output of 19V 2.6A 50W Max. My thoughts/logic is that the one should work to charge. Being a lesser amp I would not expect full output from charger, but more or less a slow trickle effect. Kind of like lowering amps on car battery to give a deeper charge. Am I correct, or would I likely mess up the computer? again input and output volts are the same and so is the plug.
