Compaq Prosignia 190 Power Adapter
If buying off-brand, make sure to check both the voltage and amperage output. Because Compaq uses one power charger that is most likely used on other laptop models, be certain you select the correct one for the Prosignia 190 model. The Compaq Prosignia 190 power adapter is responsible for two things, charging the battery and powering the laptop. When choosing a new adapter, choosing the Compaq brand one is the best one to choose. A universal power adapter is another possibility if you absolutely need to.
Clues to watch for to know your power adapter will soon need to be replaced
- Most Compaq AC adapters will get warm to the touch when they are plugged in for a period of time
- The unit will not operate using just the AC power adapter
- Your Compaq battery refuses to charge all the time
