Compaq NC6400 Power Adapter
Because Compaq uses one power charger that powers multiple other machines, be certain to thoroughly note the part number that is needed for this model. Upon choosing a replacement adapter, the actual Compaq brand will probably be the safest way to go. The Compaq NC6400 power adapter is responsible for two things, to charge up the main battery and powering the laptop. A universal power adapter is another possibility but only if necessary. If buying off-brand, make sure to check both the volts and amps outputs.
Red flags of a poorly working power adapter
- Your Compaq battery refuses to charge whatsoever
- The laptop does not run while solely using the AC adapter
- The majority of Compaq power chargers get warm when plugged in for 10 minutes or more
