Acer TravelMate 4740G Power Adapter
The Acer TravelMate 4740G AC adapter is responsible for two things, to charge up the main battery 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, double-check the part number or model number of the adapter. When choosing a new AC adapter, selecting the Acer OEM charger is always going to be the safest and easiest way to go. A universal power adapter is a possibility if you absolutely need to. If buying off-brand, it is imperative to note both the voltage and amperage output.
Clues to watch for to know your power adapter should need replacing
- Most Acer AC adapters can get quite warm when they are plugged in for a period of time
- Battery does not charge whatsoever
- The laptop does not work while solely using the AC adapter
