March 20, 2012 web AC Adapter Charger

The laptop power adapter is also known as power supply which 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.

Ac adapter buying tips

If you want to buy a new 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 canon nb-4l Battery 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 HP Pavilion dv9000 Battery 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 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 laptop Battery 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 you if it is receiving a current.
