Compaq Presario CQ42 Power Adapter
If your decision is to purchase a different brand charger, please check on both the voltage and amperage output. The Compaq Presario CQ42 AC adapter is needed for two reasons, to charge the onboard battery and to provide a source of power for the unit. Upon choosing a replacement charger, selecting the Compaq OEM charger is always going to be the safest and easiest way to go. Due to the fact that one Compaq adapter powers multiple other machines, be certain you select the correct one for the Presario CQ42 model. A universal power adapter is a possibility if you are desperate.
Major signs the Compaq power adapter should be replaced
- The majority of Compaq power chargers get warm when they are plugged in for a period of time
- Your Compaq battery refuses to charge up whatsoever
- The unit will not function while solely using the AC adapter
