Most Laptop Battery Charger Defects are Simple to Identify

The laptop charger attaches between the wall power electric outlet and the laptop, switching mains voltage AC tolow voltage DC. If the charger does not work properly then the laptop battery power will eventually discharge when you turn on and run the laptop. If the charge indicator light on the laptop doesn't light up when you connect the charger into the AC power plug and the laptop, then no power is getting into the laptop and the charger may possibly be failing or defective. There are usually three elements to the battery charger, any one of which might and sometimes does go wrong.

Probably the most obvious first step would be to replace the mains plug fuse and verify that the electrical wires are properly hooked up within the plug. Various international locations have different electric systems so yours may not have a fuse. Also, if the mains plug has at sometime been replaced, then it may have been hooked up incorrectly so really should also be checked very carefully.

Check the power wire that connects from your wall power outlet to the battery charger isn't defective. You must meticulously examine each end of the cord where it joins to the ac power connector plus the socket that attaches to the charger. If you carefully manipulate the lead you may noticedamage where it is becoming detached from the plug or socket. You will need to switch the entire wire plug assemblyif it's badly twisted, bulging or revealsany deterioration.

Check the power supply itself. If it has an indicator light thatdoes notilluminatewhen you hook it up to the wall power supply, then the fault lies with the laptop charger.You can get a faulse result result if you connect the charger to the laptop when the laptop has a motherboard fault. So you ought to always test it with the battery chargerdisconnected from the laptop. Several battery chargers do not come with an indicator lamp or the light turns on as expected when you connect the mains power. Subsequent take a look at the cord where it joins the low voltage connection that inserts in to the laptop. It is quite common for the lead to fail at this point because the end user will generally bend it sharply. Sometimes if you move around the wire the laptop charge lamp will briefly turn on and off. Look into the wire where it comes out of the charger; this often breaks particularlyif you wind the lead around the body of the charger. If somebody has broken the cable either in the connector or anyplace around its length then your complete battery charger will need changing because you can't substitute just the cable. 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,however, the low 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. Therefore , if feasible you must not coil up the cabling after making use of the laptop. A laptop charger should last longer than the laptop if it is treated with care.
