Dell Vostro 3555 Power Adapter
The Dell Vostro 3555 AC adapter provides two functions, charging the battery while simultaneously providing power for the laptop. When choosing a new AC adapter, choosing the Dell brand one will probably be the safest way to go. A universal AC adapter is a possibility if yours is unavailable or backordered. Because Dell uses one power charger that is probably used on other similar units, make sure you check the part number for the correct one. If you decide to buy an non-Dell adapter, make sure to check the output of amps and voltage.
Major indications to watch for in a failing Dell power adapter
- The unit will not function using just the AC power adapter
- Your Dell battery refuses to charge up at all
- Most Dell adapters get warm when they are plugged in for a period of time
