Two different notebook power supplies - can I use them?

I have a 60 watt (19v X 3.19amps) original power supply and a second power supply I grabbed from someone's dead notebook. It is 75watts (19 V 3.95amps). My question is this: will the more powerfull supply kill my laptop, my battery, or me? If this was a normal PC, I wouldn't worry about a more powerful power supply, but I don't know how notebooks/batteries draw power.

Yes. Your original supply is rated to provide the required current (3.19 amps) at the required, regulated voltage. The other one is rated at the same voltage. The greater current rating (3.95 amps) just means it will continue to provide the rated voltage under a greater load.

Your notebook will not draw anymore current than it needs as it operates up to the maximum available from the supply. 🙂
