Dell Precision M3800 Power Adapter
Because Dell has been known to use a single AC adapter that powers multiple other machines, make sure you check the part number for the correct one. If you decide to buy an non-Dell adapter, make sure to check both the volts and amps outputs. When purchasing a replacement adapter, choosing the Dell brand one will probably be the safest way to go. The Dell Precision M3800 AC adapter has two main uses, charging the battery and to provide a source of power for the unit. A universal power adapter can be used if yours is unavailable or backordered.
Main clues the Dell power adapter is failing
- Most Dell AC adapters get warm when plugged in for any length of time
- Battery does not charge whatsoever
- The laptop does not work using just the AC power adapter
