Acer Aspire 5749 Power Adapter
The Acer Aspire 5749 power adapter has two main uses, to charge up the main battery and powering the laptop. Because Acer has been known to use a single AC adapter that is most likely used on other laptop models, be certain to thoroughly note the part number that is needed for this model. When choosing a new AC charger, the actual Acer brand is the best one to choose. A universal power adapter is another possibility if you are desperate. If your decision is to purchase a different brand charger, it is imperative to note both the voltage and amperage output.
Signs your AC adapter is going out
- Most Acer adapters get warm when they are plugged in for a period of time
- The unit will not run while solely using the AC adapter
- Battery does not charge up all the time
