Acer TravelMate 4740Z Power Adapter
If your decision is to purchase a different brand charger, please check on both the volts and amps outputs. Upon choosing a replacement adapter, the actual Acer brand will probably be the safest way to go. The Acer TravelMate 4740Z power adapter is needed for two reasons, to charge up the main battery and to provide a source of power for the unit. Due to the fact that one Acer adapter powers multiple other machines, be certain you select the correct one for the TravelMate 4740Z model. A universal power adapter can be used if yours is unavailable or backordered.
Major signs of a poorly working AC adapter
- The laptop does not function without the battery installed
- Most Acer AC adapters will get warm to the touch when plugged in for any length of time
- Your Acer battery refuses to charge whatsoever
