Compaq NW8240 Power Adapter
When choosing a new AC adapter, the actual Compaq brand is always going to be the safest and easiest way to go. The Compaq NW8240 AC adapter has two main uses, to charge up the main battery and powering the laptop. A universal AC adapter is a possibility but only if necessary. Because Compaq has been known to use a single AC adapter that is most likely used on other laptop models, be sure you choose the right one. If buying off-brand, make note of both the volts and amps outputs.
Symptoms of a dying power adapter
- The unit will not run using just the AC power adapter
- Most Compaq adapters can get quite warm when plugged in for any length of time
- Your Compaq battery refuses to charge every time
