Compaq Presario 2100 Power Adapter
Due to the fact that one Compaq adapter is most likely used on other laptop models, double-check the part number or model number of the adapter. When purchasing a replacement charger, selecting the Compaq OEM charger is the best one to choose. If buying off-brand, make note of both the voltage and amperage output. The Compaq Presario 2100 power adapter provides two functions, charging the battery while simultaneously providing power for the laptop. A universal power adapter can be used if you absolutely need to.
General indicators that your power adapter will need replacing
- The unit will not function while solely using the AC adapter
- Your Compaq battery refuses to charge up at all
- The majority of Compaq power chargers get warm when plugged in for any length of time
