Dell Precision M70 Power Adapter
The Dell Precision M70 power adapter is needed for two reasons, to charge any and all batteries and powering the laptop. When purchasing a replacement AC charger, selecting the Dell OEM charger is always going to be the safest and easiest way to go. If you decide to buy an non-Dell adapter, it is imperative to note both the voltage and amperage output. A universal power adapter can be used if yours is unavailable or backordered. 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.
What signals that my AC adapter is not working right?
- The unit will not operate using just the AC power adapter
- Your Dell battery refuses to charge up at all
- Most Dell AC adapters will get very warm to the touch when plugged in for 10 minutes or more
