Dell Latitude D400 Power Adapter
Upon choosing a replacement adapter, selecting the Dell OEM charger is always going to be the safest and easiest way to go. If buying off-brand, it is imperative to note the output of amps and voltage. Because Dell has been known to use a single AC adapter that powers multiple other machines, be sure you choose the right one. A universal AC adapter can be used if you absolutely need to. The Dell Latitude D400 power adapter provides two functions, to charge any and all batteries while simultaneously providing power for the laptop.
Major signs the Dell power adapter is dead
- The majority of Dell power chargers can get quite warm when plugged in for 10 minutes or more
- The unit will not function while solely using the AC adapter
- Battery does not charge all the time
