Dell Vostro 2520 Power Adapter
The Dell Vostro 2520 AC adapter is responsible for two things, to charge the onboard battery while simultaneously providing power for the laptop. When purchasing a replacement AC charger, choosing the Dell brand one is always going to be the safest and easiest way to go. If your decision is to purchase a different brand charger, make note of both the voltage and amperage output. A universal power adapter can be used if you are desperate. Due to the fact that one Dell adapter is probably used on other similar units, make sure you check the part number for the correct one.
Some warnings of a bad laptop charger
- Your Dell battery refuses to charge up completely
- Most Dell adapters will get warm to the touch when they are plugged in for a period of time
- The unit will not work using just the AC power adapter
