Acer Aspire 5720 Power Adapter
Because Acer uses one power charger that is probably used on other similar units, make sure you check the part number for the correct one. Upon choosing a replacement AC charger, selecting the Acer OEM charger will probably be the safest way to go. If you decide to buy an non-Acer adapter, please check on both the voltage and amperage output. A universal power adapter is another possibility if you absolutely need to. The Acer Aspire 5720 AC adapter is needed for two reasons, to charge up the main battery while simultaneously providing power for the laptop.
Clues to watch for to know your AC adapter is dead
- Battery does not charge up at all
- The majority of Acer power chargers can get quite warm when they are plugged in for a period of time
- The laptop does not operate while just using AC power
