Toshiba Satellite U840W Power Adapter
If buying off-brand, it is imperative to note the output of amps and voltage. Upon choosing a replacement AC charger, choosing the Toshiba brand one will probably be the safest way to go. The Toshiba Satellite U840W power adapter provides two functions, to charge the onboard battery and powering the laptop. A universal AC adapter can be used if you absolutely need to. Because Toshiba uses one power charger that is probably used on other similar units, be certain to thoroughly note the part number that is needed for this model.
Subtle cues of a deteriorating laptop charger
- The laptop does not work while just using AC power
- The majority of Toshiba power chargers will get very warm to the touch when plugged in for any length of time
- Your Toshiba battery refuses to charge up at all
