Dell Vostro A90 Power Adapter
The Dell Vostro A90 AC adapter has two main uses, to charge the onboard battery while simultaneously providing power for the laptop. If your decision is to purchase a different brand charger, make note of both the voltage and amperage output. Because Dell uses one power charger that can be used on other units, be sure you choose the right one. Upon choosing a replacement charger, selecting the Dell OEM charger is the best one to choose. A universal AC adapter is a possibility if you absolutely need to.
Chief elements of a declining AC adapter
- The laptop does not work without the battery installed
- Most Dell adapters will get warm to the touch when plugged in for any length of time
- Your Dell battery refuses to charge every time
