How To Know If I Have A Faulty Laptop Ac Adapter
The main reasons that AC adapters fail are damage to the power brick from dropping or jarring it
, cord damage from pets or pests and damaging the cord by winding it or bending it repeatedly. You can extend the life of your adapter by treating it gently, never pulling the cord to remove the plug from the wall and never pinching the cord in drawers, under furniture legs or in doors. Always keep your AC adapter in a cool place and uncovered.
Plug your AC adapter into a different outlet and see if your laptop charges. If your laptop fails to charge when plugged in, a faulty power outlet rather than the adapter itself is likely to blame.
Purchase a new AC adapter and see if your laptop functions properly with it. If your laptop won't power or stay on, the problem is with the computer itself. If the battery still doesn't charge, replace your battery.
A laptop charger is considered to be the most valuable accessory of a laptop for without it the battery's energy cannot be replenished. Most of the time we forget to take care for our chargers and just place them in any surface. Often times this action can result to its destruction of the laptop charger if not initially addressed. You may think that it is just alright to simply ignore caring for our chargers but as owners of one, it is our responsibility.
Remove the battery from your laptop and attempt to use the computer with the AC adapter plugged in. If your computer still functions, your AC adapter works fine. If your battery won't charge, the problem is with the battery, not with the AC adapter.
Plug your AC adapter into another laptop of the same make and model to see if the computer functions and to see if the battery charges. If the second laptop functions properly, your laptop is likely the root of the problem.
Buying a new charger for laptop are often time consuming because you have to look for it in local computer shops if you do not have access in the internet or do not have a money account on line to pay them. So before consider buying why don't you consider taking care of it? Taking care is easy just follow these simple tips:
Before plugging the charger in the power outlet, make sure the product is made to fit the voltage circuit requirement such as 110 or 220V. The same goes with plugging the AC adapter connector in the laptop under the specific laptop model your charger serves.
If your AC power adapter is not working, it's best to eliminate the most obvious reasons before really starting to troubleshoot. Make sure that the outlet is live by plugging in another device such as a lamp. Check that the plug is secure in the wall and that the input is securely in the jack on your computer's end. You should also check that the prongs on the plug end are not broken off inside the plastic and have come loose, severing the current connection. Check the cord for fraying and damage.
If you've determined that the outlet is working, disconnect the power adapter from the computer and plug it directly into the wall, bypassing any power strips or surge protectors. Your brick, which is the black box in the middle of your cord, should have an LED light on it that, when powered, should turn green. If yours does not have an LED light, feel the brick for heat and vibrations that will tell if you if it is receiving a current.
