Compaq Presario CQ58 Power Adapter
If your decision is to purchase a different brand charger, make note of the output of amps and voltage. When purchasing a replacement charger, choosing the Compaq brand one is the best one to choose. Because Compaq uses one power charger that is probably used on other similar units, make sure you check the part number for the correct one. A universal power adapter can be used if you are desperate. The Compaq Presario CQ58 AC adapter is needed for two reasons, to charge any and all batteries while simultaneously providing power for the laptop.
General warnings to watch for in a bad laptop charger
- The laptop does not run without the battery installed
- Most Compaq adapters get warm when plugged in for any length of time
- Battery does not charge at all
