Acer Aspire 5740D Power Adapter
Upon choosing a replacement AC adapter, the actual Acer brand is the best one to choose. The Acer Aspire 5740D 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 can be used on other units, be certain you select the correct one for the Aspire 5740D model. If your decision is to purchase a different brand charger, make sure to check both the volts and amps outputs. A universal power adapter can be used but only if necessary.
How do you know if your laptop charger is not working right?
- The unit will not work while just using AC power
- Your Acer battery refuses to charge every time
- Most Acer adapters will get warm to the touch when they are plugged in for a period of time
