Asus U47A-RS51 Power Adapter
The Asus U47A-RS51 power adapter provides two functions, to charge the onboard battery and powering the laptop. When purchasing a replacement AC charger, choosing the Asus brand one is always going to be the safest and easiest way to go. Due to the fact that one Asus adapter is most likely used on other laptop models, double-check the part number or model number of the adapter. A universal AC adapter can be used if yours is unavailable or backordered. If you decide to buy an non-Asus adapter, make note of both the volts and amps outputs.
Symptoms of a defective Asus power adapter
- The laptop does not function while just using AC power
- Your Asus battery refuses to charge all the time
- Most Asus AC adapters will get warm to the touch when plugged in for any length of time
