Compaq Presario 1100 Power Adapter
The Compaq Presario 1100 AC adapter has two main uses, to charge up the main battery while simultaneously providing power for the laptop. Because Compaq uses one power charger that is probably used on other similar units, double-check the part number or model number of the adapter. If your decision is to purchase a different brand charger, it is imperative to note the output of amps and voltage. When purchasing a replacement charger, selecting the Compaq OEM charger will probably be the safest way to go. A universal AC adapter is another possibility if you absolutely need to.
Signs the power charger has very little life left
- Battery does not charge up at all
- The laptop does not run using just the AC power adapter
- Most Compaq adapters get warm when plugged in for any length of time
