Replacement Battery

A laptop power supply – also known as an A/C adapter and power brick – serves in the exact same capacity as a desktop or tower power supply in that it converts alternating current into direct current which your computer can then use. Most power bricks had an LED light that illuminates to let you know when power is available. However, even though the light may be illuminated on the power brick, there may not be enough voltage to actually charge the laptop due to damage, burn-out, or another reason. With an Ohm Meter, you can easily test an A/C adapter to see if it is supplying enough voltage.

Instructions
1.

Plug the A/C adapter directly into a wall outlet. Make sure the power cable is securely inserted into the power brick.
2.

Locate the A/C adapter’s output voltage,like Toshiba PA3715U-1ACA adapter Voltage ratings are usually located on the bottom of the power brick.
3.

On the Ohm Meter, plug the red wire into the slot marked with a + sign -this is positive. Plug the black wire into the slot marked with a – sign – this is negative. Make sure to plug the ends in without the plastic handles.
4.

Set the Ohm Meter to DCV (Direct Current Voltage) and make sure it is set to a number higher than the voltage listed on the power supply. Usually you will set the Ohm meter to the number 50.
5.

Place the tip of the of the black conductor on the outside edge of the Toshiba PA3468E adapter.
6.

Place the tip of the red conductor inside the adapter.
7.

To verify if power is being supplied, look at the needle reading; it should land on the voltage marking near the voltage listed on the back of the power supply.

If your laptop charger cable has suddenly stopped working it is likely the result of a short in the wire. If you have some extra time on your hands, you can find this short and try to repair the cable yourself. You’ll save money by not buying a whole new charger cable and the process doesn’t require very much knowledge of electronics.

Turn on your notebook computer and plug the adapter cord into the port on the computer.

Run your finger along the length of the Samsung laptop adapter cable, pinching it as you go. When the LED light at the end of the adapter flashes on and off you have found the short in the wire.

Use the stripper portion at the top of your wire cutters to strip about an inch of sheath off of the cable where the short is. Be careful to only strip the sheath and not the wire.

Twist the frayed ends of the wires together to reestablish the connection.

Wrap electrical tape around the gap in the sheath, being sure to cover the gap completely.

Laptop computers come with AC adapters designed specifically for the system. The adapter may operate with other systems as well, but use of an incorrect power source can damage the laptop hardware.

Compatibility
Each adapter has values for its input and output in terms of voltage and polarity. For the hp laptop adapter to be compatible with another system, these values must match the power needs of that computer. Reference the system’s documentation or its original adapter for specific information on power requirements.

Components
Most Toshiba laptop adapters come in two parts: a cord that connects to a wall socket and the adapter that connects to the computer. These two components also must be electrically compatible with each other to supply the correct amount of power.

Ports
Different manufacturers use different ports and hardware configurations with their adapters. Even if an SAMSUNG laptop adapter is electrically compatible with another system, it may not physically connect due to incompatible port configuration.

As soon as a laptop battery is built, the clock begins ticking on its lifespan. At most, a laptop battery can last around five years. However, if the battery is not cared for properly, you may find yourself needing to replace it after just one or two years. Purchasing a new laptop battery is an expensive investment; exercise proper care to maximize its lifespan.

Avoid using your laptop on plush surfaces or carpets, which prevent air from entering and leaving the unit freely. All of the Acer Laptop Battery laptop’s components must remain cool for the longest possible lifespan, and this includes the battery.

Avoid using the laptop on battery power until the laptop is completely dead. When lithium-ion batteries are allowed to discharge completely, their maximum capacity can be permanently reduced.

Remove the battery from the laptop if the laptop is connected to a reliable power source and will remain so for an extended period. When a laptop is running on AC power, the battery is regularly “topped off” by the charger. Asus Laptop Battery This keeps the battery within higher temperature ranges than it should be stored at, and the repeated “top-off” charges cause wear.

Store the laptop in a comfortable room-temperature environment when it is not being used. High temperatures will cause the maximum capacity of the battery to be decreased, even when the battery is not in use.

Avoid placing the battery into long-term storage with a completely full or empty charge. Dell Laptop Battery If the battery will not be used for a prolonged period, place it into a zip-top plastic bag and store it in the refrigerator charged to about 40 percent of its maximum capacity.

If you own a laptop, you may at some point notice that its laptop adapter has failed or is deteriorating, with wires suddenly exposed. Over the last few years, Dell laptops have been known as being faulty, and the adapter is no exception. However, with the right tools, skill and caution, you can repair your adapter by yourself.

Instructions
Examine the LED light that is on when your Dell laptop’s adapter is plugged in and is in working condition. If the light blinks when you wiggle the power adapter while it’s plugged in, it means there is a problem, possibly a short in a wire inside it.

Turn off your Dell laptop and unplug the adapter as well. Then, open the Dell adapter’s clamshell case by using a 7mm flat-headed screwdriver, inserting it between the clamshell and the AC power socket (two- or three-pronged). Keep the blade close to the outer edge of the socket and twist clockwise and counter-clockwise alternately in an attempt to get the clamshell to pop open on either or both sides.

Use either the screwdriver or a 7-mm thin Swiss army knife to cut a crack along the edge of the clamshell, then utilize the blade to expand the crack by about an inch and a half. Separate the outer layer from the interior and tightly twist it.

Cut off the large choke, also known as a ferrite, on your Dell adapter if it is too close to the barrel connector. Use a wire stripper to do this so that you can strip the coax rather than having to sheath away with a cheap tool. Strip away about one inch of the outer sheath, then twist the braid shield together.

Use the knife to remove about 1/4 inch of the insulation from the center electrode and tightly twist it, using a soldering iron to seal the connector. Use electrical tape on it if your soldering is not perfect.

With some skill and much caution, you can repair your Dell laptop’s adapter.

Laptop batteries power the laptop when it is not or cannot be plugged into an electrical outlet. This makes the laptop portable, allowing the user to use the laptop whenever and wherever they choose. Laptop batteries have a normal life span of 12 to 36 months. During this time, the battery life will slowly diminish, meaning the battery won’t be able to power the laptop for as long. However, reconditioning the battery can help recover or restore some of the lost efficiency on NiCD or NiMH batteries. There is no way to restore or recover a lithium ion battery and draining the battery should not be purposely done.

Instructions
1.Plug the AC adapter into the laptop.such as Samsung Laptop Batteries Allow the battery to fully charge. This process will take four to eight hours depending on laptop battery type and size.

2.Remove the AC adapter. Turn the laptop on.
3.Allow the laptop battery to continue to provide power to the laptop until the battery is completely drained. Once the laptop shuts off, the battery has been drained, or discharged.

4.Perform this process a total of three times prior to the batteries first use and every three months thereafter. You can also go through this process when you notice a loss of efficiency. If you do not perform this process, you may not get full life from the battery.

A laptop charger supplies a laptop with energy while it is plugged into an electrical outlet. The energy charges the computer’s battery while also powering the computer. There are several reasons a laptop charger may need repairs. For example, the charger may become frayed so that the plastic exposes the wiring. If the charger is frayed, it may no longer work to charge the computer and could become a fire hazard. Many laptop charger repairs can be completed without taking the computer to a repair shop.

Examine the laptop charger to look for bent and frayed areas in the cord. Also look at the portion of the charger that plugs into the computer to see if any pins are bent or dirty. Look at the plug that goes into the wall to ensure that the pins are secure and straight.

Clean the portion of the charger that goes into the computer. If the metal components of the charger are dirty or bent, they will not properly connect within the computer, which means that it may not charge correctly. Use a cotton swab and isopropyl alcohol to wipe the surface of the metal and pins.

Move any stuck or bent pins within the portion of the charger that is inserted into the computer. If a pin is stuck or bent, the charge may not transmit to the computer properly. Use your finger to gently move or straighten the pins.

Repair any frayed areas of the cord using a silicone sealer. Protect the area you are working on by laying down painter’s tape. Smooth sealer over the frayed area and allow it to dry according to the directions on the product label.
