Acer Aspire 4720 Power Adapter
The Acer Aspire 4720 AC adapter provides two functions, to charge up the main battery and to provide a source of power for the unit. Because Acer uses one power charger that is most likely used on other laptop models, double-check the part number or model number of the adapter. If your decision is to purchase a different brand charger, make note of the output of amps and voltage. A universal power adapter is a possibility if you absolutely need to. When choosing a new adapter, choosing the Acer brand one is always going to be the safest and easiest way to go.
Symptoms of a poorly working Acer power adapter
- The laptop does not function using just the AC power adapter
- Most Acer AC adapters will get warm to the touch when plugged in for 10 minutes or more
- Your Acer battery refuses to charge every time
