Compaq 6720T Power Adapter
When choosing a new charger, choosing the Compaq brand one is the best one to choose. Because Compaq has been known to use a single AC adapter that is most likely used on other laptop models, be certain to thoroughly note the part number that is needed for this model. A universal AC adapter is a possibility if you are desperate. The Compaq 6720T power adapter has two main uses, charging the battery while simultaneously providing power for the laptop. If your decision is to purchase a different brand charger, please check on both the volts and amps outputs.
General indicators that your AC adapter is not going to last much longer
- Your Compaq battery refuses to charge up at all
- The laptop does not function while just using AC power
- Most Compaq AC adapters will get warm to the touch when they are plugged in for a period of time
