Acer Extensa 670 Power Adapter
Due to the fact that one Acer adapter powers multiple other machines, make sure you check the part number for the correct one. The Acer Extensa 670 AC adapter is needed for two reasons, to charge the onboard battery and powering the laptop. If you decide to buy an non-Acer adapter, make note of both the voltage and amperage output. When choosing a new AC adapter, choosing the Acer brand one is the best one to choose. A universal AC adapter can be used if yours is unavailable or backordered.
Cues to watch for in a failing laptop charger
- The laptop does not work while just using AC power
- Most Acer AC adapters will get warm to the touch when they are plugged in for a period of time
- Your Acer battery refuses to charge at all
