How to detect Samsung laptop power adapter failure?

 Samsung AC adapter (Power adapter) is a small portable electronic devices and electronic power supply conversion equipment, generally it consist of the shell, power transformers and rectifier circuit, according to the type of output can be divided into AC output and DC output type; by connection Divided into wall-mounted and desktop type. Widely supporting the telephone machine, game consoles, language repeater, Walkman, notebook computers, cell phones and other equipment.

Step 1: First, gently shake the power connector or battery to check whether the power adapter or notebook battery is well connected, if not normal, try to reinstall the AC adapter or battery. Possible fault conditions are the deformation of the power connector or the drop in battery contact.

Step 2: If the power supply or battery connector is good, the multimeter can be used to measure the output voltage of the AC adapter or battery to see if the output voltage is stable and whether the actual output voltage matches the nominal voltage of the power supply. If the output is unstable or the actual output voltage Discrepancies with product specifications, you need to replace the damaged AC adapter or battery.

Step 3: If the above detection steps are normal, you can infer the failure in the laptop power board or motherboard, here to open the laptop shell, and check the power board and the motherboard are in good contact.

Step 4: If the power board and the battery are in good contact, then use the DIY commonly used replacement method to check the power board is normal, if not normal, it should be replaced.

Step 5: If the above method to confirm the power board, battery are normal, it can be inferred that the laptop motherboard or other main components damaged (such as the boot circuit fault), then repair or replace the motherboard.

Laptop power adapter can be mixed?

My laptop's AC adapter is broken, I still have an old laptop. Can I use the old laptop's AC adapter to a new laptop?  If I use the old laptop's AC adapter to a new laptop, whether it will harm to my new laptop?

In general, the same brand of laptop power adapter, as long as the same wattage, the same interface, can be mixed. But do not recommend different brands or different wattage power adapter mix. Because of the different output wattage, it may cause harm to the laptop, such as voltage instability.

At present, the power of notebooks on the market is generally 90 watts and 65 watts, using integrated graphics, or low-end notebook configuration, is generally 65 watts. The use of independence alone, the configuration of high-end, or video games, are generally 90-watt. If the laptop's AC adapter is damaged can not be used, it is best to send the adapter to repair department to repair as soon as possible. If it is for emergency, check whether the two adapter output power and current voltage is the same before use. as the adapter's input current and voltage is not important to the general household voltage is 220V, so almost all laptop power Adapter is 100-240V ~ 1.5A words, as long as the output current and voltage values, and the same wattage, and then the same interface, you can mix. In general, the voltage stability, the same output wattage, no harm to the laptop.
Need to explain: Generally stated on the power AC adapter output voltage and current number, did not indicate the wattage, you need to calculate. Just the number of voltage and current multiplied by the number that is wattage. Multiplying the current by the voltage is equal to the wattage.

How to choose the power adapter?

When we buy goods, we will consider what brand, quality, price and so on. In fact, the purchase of latop AC adapter is the same, we will carefully consider before buying what brand, effect, noise, stability, convenience, etc. However, after use, all the disadvantages will be ignored, can be used is good, Unless it is really can not be used, will consider to replace. Next, I will tell you what kind of power adapter is a good adapter?

What we need to consider?

Stability

The stability of power adapters are mostly the same, all based on the over-current protection, EMI radiation, voltage deviation, ripple suppression, cross load, timing, dynamic test and so on the performance of the project, to come to whether the power AC adapter can be stable operated for a long time.

Depending on the environment, the performance of the data is also different, the stability will not be the same. Japan, the United States, Canada, etc., mains voltage is 110V, the stability of the power adapter in these two cases are different, but the power adapter has a 20% voltage fluctuation range, to use abroad, then do not worry too much.

Convenience

Convenience is one of the main factors for everyone to consider. Electronic products itself is for convenience reasons, slowly toward the small and sophisticated direction, the power adapter is the same naturally, I believe no one will be willing to carry large things. Convenience is based on the laptop AC adapter measurements, size, weight to consider, some light power adapter, its price will naturally be slightly higher.

Energy-saving

Now, we advocate a green trip to save energy, I believe we can understand. Power adapter is mainly used for conversion efficiency, the initial power conversion efficiency of only 60%, with the progress of technology and development, generally can reach more than 70%.
Another is the no-load loss, referring to the case of electronic products in standby, power AC adapter power loss. According to the different materials inside the power adapter, the loss rate is not the same. So when we do not use electronic products, it is best unplug the power AC adapter to save energy.

Durability

Durability can be used as a measure for all items except food. Due to the power adapter environment, its durability is relatively important. In addition to the normal use of connecting the electricity and electronic equipment, we often take the laptop  AC adapter everywhere, some bumps are inevitable, and the wire will be frequent folding, which determines its aging faster, the service life Will decrease.

Compatibility

As the power adapter does not have a unified interface standard, so the products on the market are different in the interface, when you select the laptop power adapter, you need to carefully compare, to avoid buying the wrong.
Another reason is that power adapters usually have voltage bumps. Power adapters with similar voltage levels are compatible as long as they do not exceed the maximum range of electronic products.

What do you need to pay attention to?

Power adapters, as electronic products. It will corrode or oxidize their internal electronic components to varying degrees if they are accidentally filled with water or exposed to damp conditions for extended periods of time.
laptop power AC adapter is actually a fragile electronic components, the internal components can not be beat. In particular, to prevent falling from a height during use, do not throw, beat or vibrate the charger. Rough handling of the charger will destroy the internal circuit board and cause a malfunction.
Do not place the charger where the temperature is too high. High temperatures will shorten the life of the electronics, destroy the charger and cause some plastic parts to deform or melt. Do not store the charger in an overcooled place. When the charger is operating in a cold environment, the internal temperature will increase and moisture will form inside the charger, damaging the circuit board.
You need to periodically clean the power AC adapter charging interface. When cleaning, use a damp cloth, or best to prepare a good quality antistatic cloth. Remember never to use dry cloth.
Power adapter in the cleaning do not use strong chemicals, cleaning agents or strong detergent. If you remove the appearance of the charger stains, you can use cotton with a small amount of anhydrous alcohol scrub.
