Acer Aspire E5-491G Power Adapter
The Acer Aspire E5-491G power adapter is responsible for two things, to charge any and all batteries and to provide a source of power for the unit. Due to the fact that one Acer adapter is most likely used on other laptop models, make sure you check the part number for the correct one. If you decide to buy an non-Acer adapter, it is imperative to note both the volts and amps outputs. A universal AC adapter is another possibility if you absolutely need to. When purchasing a replacement AC adapter, selecting the Acer OEM charger is usually going to be the safest choice.
Signals to watch for in a bad Acer power adapter
- The majority of Acer power chargers get warm when plugged in for any length of time
- Battery does not charge up at all
- The unit will not operate while just using AC power
