Compaq Armada 4200 Power Adapter
Because Compaq has been known to use a single AC adapter that is most likely used on other laptop models, make sure you check the part number for the correct one. If your decision is to purchase a different brand charger, make sure to check the output of amps and voltage. When choosing a new charger, choosing the Compaq brand one is usually going to be the safest choice. A universal power adapter is a possibility if you absolutely need to. The Compaq Armada 4200 AC adapter is responsible for two things, to charge the onboard battery and to provide a source of power for the unit.
Important clues of an unhealthy Compaq power adapter
- Most Compaq adapters will get very warm to the touch when plugged in for 10 minutes or more
- Battery does not charge up every time
- The laptop does not function without the battery installed
