Hardly ever, the battery charger itself might stop working; this can be difficult to diagnose with out substituting it with a replacement.

Laptop chargers do not generally fail, nonetheless, the reduced voltage lead and connector frequently stops working because of the wire fracturing particularly if a person has bent it sharply or wound it around the battery charger.
