Acer Aspire ES1-331 Power Adapter
When choosing a new AC adapter, selecting the Acer OEM charger is always going to be the safest and easiest way to go. The Acer Aspire ES1-331 AC adapter is needed for two reasons, charging the battery while simultaneously providing power for the laptop. Because Acer has been known to use a single AC adapter that can be used on other units, double-check the part number or model number of the adapter. If buying off-brand, make note of both the volts and amps outputs. A universal AC adapter is another possibility if you are desperate.
What are the signs that the Acer power adapter is not working right?
- Your Acer battery refuses to charge up completely
- Most Acer AC adapters will get very warm to the touch when they are plugged in for a period of time
- The unit will not work while just using AC power
