Compaq Presario CQ40 Power Adapter
If your decision is to purchase a different brand charger, please check on both the volts and amps outputs. When choosing a new adapter, selecting the Compaq OEM charger is the best one to choose. Because Compaq uses one power charger that can be used on other units, be certain to thoroughly note the part number that is needed for this model. A universal power adapter is a possibility if yours is unavailable or backordered. The Compaq Presario CQ40 power adapter is needed for two reasons, to charge the onboard battery while simultaneously providing power for the laptop.
What symptoms are present when the Compaq power adapter is in need of replacing?
- The unit will not function without the battery installed
- Your Compaq battery refuses to charge up completely
- Most Compaq AC adapters get warm when plugged in for 10 minutes or more
