Compaq Presario 1800T Power Adapter
If buying off-brand, make sure to check the output of amps and voltage. Because Compaq uses one power charger that powers multiple other machines, be certain you select the correct one for the Presario 1800T model. The Compaq Presario 1800T AC adapter provides two functions, to charge up the main battery and to provide a source of power for the unit. Upon choosing a replacement charger, the actual Compaq brand will probably be the safest way to go. A universal AC adapter is a possibility but only if necessary.
Signals the Compaq power adapter will need to be replaced
- The majority of Compaq power chargers will get very warm to the touch when they are plugged in for a period of time
- Battery does not charge up at all
- The laptop does not work using just the AC power adapter
