Dell Precision M4700 Power Adapter
The Dell Precision M4700 power adapter is needed for two reasons, to charge up the main battery and powering the laptop. When purchasing a replacement charger, the actual Dell brand is always going to be the safest and easiest way to go. A universal AC adapter can be used if you are desperate. Due to the fact that one Dell adapter can be used on other units, make sure you check the part number for the correct one. If you decide to buy an non-Dell adapter, it is imperative to note both the volts and amps outputs.
Signals the power charger has to be replaced
- Your Dell battery refuses to charge up completely
- Most Dell AC adapters can get quite warm when they are plugged in for a period of time
- The unit will not operate without the battery installed
