Alienware 17 R1 Power Adapter
Because Alienware uses one power charger that powers multiple other machines, be sure you choose the right one. The Alienware 17 R1 AC adapter is needed for two reasons, to charge any and all batteries and to provide a source of power for the unit. If you decide to buy an non-Alienware adapter, please check on both the voltage and amperage output. When choosing a new charger, selecting the Alienware OEM charger is the best one to choose. A universal AC adapter is another possibility if you are desperate.
Indications your power adapter is failing
- The majority of Alienware power chargers can get quite warm when they are plugged in for a period of time
- Your Alienware battery refuses to charge at all
- The unit will not run without the battery installed
