Compaq Armada 7400 Power Adapter
The Compaq Armada 7400 power adapter is responsible for two things, to charge the onboard battery while simultaneously providing power for the laptop. If you decide to buy an non-Compaq adapter, please check on both the voltage and amperage output. Due to the fact that one Compaq adapter powers multiple other machines, make sure you check the part number for the correct one. A universal AC adapter is a possibility if you are desperate. When purchasing a replacement adapter, the actual Compaq brand is the best one to choose.
Red flags of a defective charger
