Most Laptop Battery Charger Defects are Simple to Identify
The laptop battery charger connects in between the wall power electricity plug and the laptop, changing mains voltage AC to reduced voltage DC. If the charger does not work properly then the laptop battery power will ultimately discharge when you switch on the laptop.
You will find three items that may fail connected with the laptop battery charger; if any fail then the battery pack will no longer be charged and the laptop may at some point shut off due to a lack of power. If the power light does not come on after you link up the electric power pack then it may possibly be faulty. You will find three parts to the laptop electrical power supply, any can fail preventing the battery recharging or directly powering the laptop. Ultimately the battery will run out of power and the laptop will probably fail to operate. Should the laptop charge lights no longer turn on then it is most likely that the laptop charger is not supplying energy.
Probably the most obvious steps 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 exactly where it joins to the ac power connector plus the socket that attaches to the charger. If you carefully manipulate the lead you may notice exactly where it is becoming detached from the plug or socket. You will need to switch the entire wire plug assembly when it's badly twisted, bulging or reveals slight deterioration.
Check the power supply itself. If it has an indicator light that will not illuminate if you hook it up to the wall power supply, then the fault lies with the laptop charger. This can nonetheless can provide the wrong result in the event you connect the charger to the laptop when the laptop has a motherboard fault. So you ought to always test with the battery charger shut off 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 particularly should 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, 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. Therefore , if feasible you must not coil up the cabling right after making use of the laptop, but do detach it from your wall power plug to save electricity.
