Buying a new Ac Power Adapter, you should follow this rule:
The adapter’s output voltage (V) must be the same such as for original one, also the amperage (A) could be the same or higher than on the original ac power adapter.

Example: If my laptop requires 16(V) - 3.5(A) ac adapter, I can also safely use 16(V)-3.9(A) ac power adapter.
