Dell Studio 1749 Power Adapter
Upon choosing a replacement adapter, selecting the Dell OEM charger is always going to be the safest and easiest way to go. Because Dell has been known to use a single AC adapter that is probably used on other similar units, be sure you choose the right one. A universal AC adapter is a possibility but only if necessary. If your decision is to purchase a different brand charger, make sure to check both the voltage and amperage output. The Dell Studio 1749 power adapter is needed for two reasons, charging the battery and powering the laptop.
Major warnings to watch for in a failing Dell power adapter
- Battery does not charge up whatsoever
- The unit will not work while just using AC power
- Most Dell AC adapters will get warm to the touch when plugged in for 10 minutes or more
