@R3drooster

If you want to be positive look on the bottom of your laptop.

Look for the input voltage. "It could be under the battery"

Goto Teng Da Xing to know more.

It should be 18.5V  and  6.5A or 4.74A.

V x A = Watts

@R3drooster

You can use one of the following adapters

120-W AC adapter part # -001
90-W AC adapter part # -001

65W is probaly not enough power to run your computer. My motebooks normally have 3 AC adpters:

(a) Normal can be x W,

(b) Travelling (lighter) can be 70% to 80% of x W,

(c) For docking station can be 1.3 to 1.5 of x W.

For example x = 90W, traveling AC adapter is around 65 W and the one for docking station can be from 120W to 135W.

Regards.
