Dell XPS M140 Power Adapter
When purchasing a replacement AC adapter, choosing the Dell brand one is usually going to be the safest choice. Due to the fact that one Dell adapter is most likely used on other laptop models, double-check the part number or model number of the adapter. The Dell XPS M140 power adapter is needed for two reasons, to charge up the main battery and to provide a source of power for the unit. A universal power adapter can be used if you absolutely need to. If your decision is to purchase a different brand charger, please check on both the volts and amps outputs.
Important signs the Dell power adapter will eventually need to be replaced
- Battery does not charge up whatsoever
- The majority of Dell power chargers can get quite warm when plugged in for 10 minutes or more
- The laptop does not work using just the AC power adapter
