Gateway 3100 Power Adapter
The Gateway 3100 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 Gateway adapter is most likely used on other laptop models, make sure you check the part number for the correct one. A universal power adapter can be used if you are desperate. If your decision is to purchase a different brand charger, please check on both the volts and amps outputs. When choosing a new adapter, selecting the Gateway OEM charger is the best one to choose.
Signs the power charger will eventually need to be replaced
- Most Gateway AC adapters can get quite warm when they are plugged in for a period of time
- Your Gateway battery refuses to charge every time
- The laptop does not function using just the AC power adapter
