If you are looking for a new adapter, you should check the following:
1. Your new adapter must have exactly the same plug (adapter tip) as the original one.
2. The output voltage must be the same, the amperage could be the same or a little higher than on the original power adapter. For example, if my laptop requires 19v-3.42A adapter, I can safely use 19v-3.95A adapter.
3. Polarity on the new adapter’s plug must be the same as on the original one.
