So... i go out of town to visit my friend, and i left my laptop power supply at home.

i have an alienware m11x r1, power supply is 65w and i think 19.5v 4.62a

my friend here has a hp dv8t with a 90w power, and output is 19v, 4.74A

can i use my friends charger, or will that kill my laptop, even thought volts are 0.5 less

his power supply fits but im not sure if i should use it or not...

It should work, the watts is only the driving power of the power supply, its the volts that matter in this case.

Since the volts and Amps are within range of the specified requirements it should work.
