Acer Aspire 8942 Power Adapter
When purchasing a replacement AC adapter, the actual Acer brand is the best one to choose. If you decide to buy an non-Acer adapter, please check on both the voltage and amperage output. The Acer Aspire 8942 AC adapter is needed for two reasons, to charge the onboard battery while simultaneously providing power for the laptop. Because Acer uses one power charger that can be used on other units, be certain to thoroughly note the part number that is needed for this model. A universal power adapter is another possibility if you are desperate.
What are the indications that my Acer power adapter is not working right?
- The unit will not run while solely using the AC adapter
- Battery does not charge every time
- Most Acer adapters get warm when they are plugged in for a period of time
