Dell Inspiron 640M Power Adapter
If buying off-brand, please check on both the volts and amps outputs. The Dell Inspiron 640M AC adapter is needed for two reasons, charging the battery and powering the laptop. A universal power adapter can be used if you absolutely need to. Due to the fact that one Dell adapter powers multiple other machines, be certain you select the correct one for the Inspiron 640M model. Upon choosing a replacement AC charger, selecting the Dell OEM charger is usually going to be the safest choice.
Clues poorly running charger
- The laptop does not operate using just the AC power adapter

- Battery does not charge completely

Please be sure to note the part number before placing an order for a new power adapter. The Dell laptop will be better off if you buy the right parts. Dell Inspiron 640M power adapter is going to be better in brand new condition for a variety of reasons, including wear and tear on any older used one. Be sure to always get computer parts from a site you know if you purchase through a website.
