Troubleshooting Dell Laptop AC Adapter problems

The laptop computer power adapter as also known as power supply and is usually molded as a brick.  This converts high volatge electrical current  electricity from a wall outlet into the required low voltage  DC which is needed to power your notebook.

The adapter supplies the necessary voltage for the laptop to power on, charge the battery and run the various other parts that make up your notebook. It is very important to purchase and use the proper adapter.  Buying and installing an incorrect adapter can cause damage to your laptop or simply not power it on.  As for Dell laptops , for example, the Dell laptop battery charger has a label with a barcode on it.  The Dell part number is imprinted on this sticker and it begins with “CN” or “D/PN” followed by a series of numbers.  The first set of numbers is your part number.  With this number you can now locate the correct charger or a compatible one .

Ac adapter buying tips

If you want to buy a new NIKON EN-EL9 Battery charger, check the adjacent notes:
1. Your new charger needs to have the same plug (adapter tip) as the original one.
2. Your new charger must output the same voltage as the original one.
3. The polarity on the new adapter’s plug must be the same as on the original OEM  one.

You can find the output voltage and amperage on a label behind the adapter.  Also when you buy a new adapter, you can follow this simple rule: The output voltage must be identical, the amperage can be similar or higher than the original unit. For example, if your laptop requires a 19v-3.42A adapter, you can safely use a 19v-3.95A charger.

How to test or restore a laptop AC charger?

Most newer notebook power chargers are plastered and you cannot open and repair them.  If the adapter is dead  it is highly recommended, and usually much more cost effective, to purchase a new one.

How can you tell if the AC charger is dead?  Well, you can try testing it with a voltmeter.  Let’s say you are testing a 15V adapter and the output is 15.45V.   That is normal and there is nada actually wrong if the output voltage reads a bit higher.  But, if you are getting 0V, the adapter is by all odds DOA or “dead.”

Now, if you accidentally have broken  the adapter plug, you can try replacing it with a new one.  Just make sure the new tip has the same size as the old one.  Take out or cut off the old damaged plug and solder on a new one.  It is wise to have some sort of technical skill before attempting to repair the dell inspiron 1420 battery charger.  Always unplug the battery charger from the wall outlet before attempting a repair.

It would be hard to dispute that your laptop AC adapter may be the single most important piece of equipment you need. Without it, you wouldn’t be able to use your computer after an hour or two. AC adapters run your computer and recharge the battery. Unfortunately, they do not last forever and they can be quite expensive to replace.

Eliminate the Obvious

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.

Check the Power Brick

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.

How to do When Your Battery Won’t Charge?

If your battery won’t charge and you’ve eliminated the obvious reasons concerning your adapter, you might want to take a look at your battery. Turn off your computer, remove the battery and check the connectors to make sure they are free of damage and debris. Replace the battery, making sure it fits properly and locks into place, and then reboot your computer.

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.

Use Your Laptop AC Adapter efficiently

Many people  use a laptop day and and night, and it becomes an neccessity for human beings.  For them, they may reache an agreement that laptop AC adapter is the most frugail part of the laptop. Most people have accepted this as a reality and just buy a brand new one when the  last one  go to hell.

Let’s give you some tips as followed, take my dell laptop as an example,

1.keep water away from inside the adapter. As we know, the laptop AC adapter is  small and it can be taken with the user very easily. But the structure in the inside of it is very dedicated and compact. If it is fallen into water or flooded in water, that will get into the inside of it and the adapter may not work as usual because the inside part is damaged and the electricity can’t be connected to the laptop well. Sometimes the laptop AC adapter will get shut off suddenly. So please keep the HP Pavilion dv6000 Battery AC adapter far away from water.
2. keep it cool. Many people pay a lot attention to the heat of their laptop and usually take many measures to keep the heat elimination good. But there are few people to take good care of that of their AC adapter. In fact, laptop AC adapter get hotter as the laptop is used. If the heat elimination is not good, the laptop AC adapter is damaged easily. So remember not to put the laptop AC adapter on the cotton or some other things where the heat elimination is not good.
3. Do not charge and discharge it often.  the cord and the power suplier will be seperated and very loose.
4. Know the part number. If you by accident destroy your adopter, know the number as mine is Dell PA-10. Then you can get a replacement efficiently. For it’s easy to find one which number is PA-10. Then check the reviews and the stars represent by the customers.
