If the charger does not work then the laptop battery will eventually discharge as soon as you start up the laptop. When the re-charge warning light on the laptop doesn't illuminate after you hook up the battery charger to the electric outlet and the laptop, and then no electricity gets to the laptop then a battery charger may be faulty. You'll find often three parts to the charger, any one of which can and sometimes do fail.

One of the most obvious steps is usually to change the AC power plug fuse and examine that the wires are properly attached inside the plug. Various nations around the world have a variety of electrical systems so yours may perhaps not need a fuse. Additionally, if the AC power plug has at sometime been modified, then it may possibly have been hooked up wrongly so really should be checked very carefully.

The mains cord should be carefully inspected making sure that it has no breaks or bulges. Check specially at the ends by gently twisting the cord and making sure that the insulating material hasn't started to come out from the power cord. If there's any chance that the plug or cable is defective or broken it ought to be swapped out for safety reasons.

The laptop battery charger itself hardly ever fails and might only be identified by substituting an alternative, even so, the low voltage wire and connection very regularly fail. Look at extremely thoroughly exactly where the cable joins the low voltage connector that plugs into the laptop; this very often stops working if the wire was bent forcefully. If you try shifting the cord very slightly the laptop may perhaps swap recharging and not charging. Additionally look at just where the reduced voltage cable leaves the charger, this will often break at this point particularly if the cord is regularly wound round the charger box. Unfortunately, if the reduced voltage cable or connector interconnection is broken or cracked in any way then the entire charger will have to be swapped out.

Laptop chargers do not generally break, having said that, the reduced voltage cord and connection usually breaks because of the lead fracturing particularly if someone has bent it sharply or wound it about the battery charger. Therefore if feasible you must not coil up the cords following utilizing the laptop, however do remove it from your ac power socket.
