Laptop AC adapters are an important component of any laptop. Without them, users will be left without power or the ability to recharge the battery. Since AC adapters are an external part, however, they can often take a lot of abuse, leading to failure. Here we will examine some of the most common failure points for laptop AC adapter. 

Without a doubt, the most vulnerable parts of a Laptop AC adapter is it’s cables. Most designs incorporate a thin cable connecting the laptop to the transformer, and then a thicker cable from the transformer to the wall outlet. The thin cable is often the most susceptible to damage. It can get bent sharply, wrapped too tightly, or even kinked or knotted, causing damage to the cables inside. When this happens, there will often be a short in the cable, causing intermittent problems. Some Gateway AC Adapters utilize a 90 degree curved adapter plug that minimizes the stress on the connection at the laptop and many aftermarket ac adapters include this feature. In some cases, wiggling the cable will cause the adapter to work again temporarily, but it is recommended that it be replaced to avoid any risk of electric shock.

Another common failure point for AC adapters is the connectors. There is often a connector between the AC cable and transformer, and another where the DC cable plugs into the laptop itself. This connector is often fairly small by necessity and prone to damage over time as the user continually plugs and unplugs the connector. In some cases, the internal connector of the laptop can also become damaged, so it is a good idea to determine which part is defective before replacement.

The transformer is contained within the large “brick” part of an AC adapter. It is less likely to be damaged than other components because it is designed to be rugged. Nevertheless, repeated dropping or other types of abuse can sometimes cause the adapter to malfunction, and it will need to be replaced.

When you have determined that your AC adapter needs replaced, you can visit an online retailer and search for your model to find a replacement part. You can also try doing a more general search, like Dell Laptop AC Adapter or one that pertains to your brand of laptop.

Different users have different using habits in regular work so that the laptop system and Li-ion battery will perform differently from each other in many aspects. Each time after completing work on the laptop, have you unplugged the Laptop AC adapter from the motherland computer to provide it a good rest to cool down and save power energy? Actually, the radiation of the charging adapter is also very powerful if not disconnected.

Will the HP pavilion dv5000 adapter charge the lithium-ion battery and computer after shutting down? 

After shut down, the whole computer device will have a full rest without getting any power energy from external resources. As a matter of fact, the lithium-ion batteries won’t be charged after being full even though the power supply is connected with it. Of course, if the battery is not full, the charger will supply power energy to the battery after full. 

Why the plug and pin are of high work temperature even if the laptop computer is off? 

It is truth that when the laptop is shut down, the adapter is also working. Of course, the mains supply won’t reach other laptop accessories rather than the adapter itself. The self-charging has occurred to the adapter as long as the socket is connected with the plug pins. If possible, users had better disconnect HP pavilion dv5000 adapter and cool it down to maintain the whole charger in good performance to get longer lifespan. 

The dangerous influence from laptop AC adapter in radiation

As is known to all, radiation is harmful to our health while that of HP pavilion dv5000 adapter is powerful enough if users haven’t unplugged the charger when sleeping every day. Of course, it will also waste electric charge to some extent. If the battery happens to be deep discharge, users can leave some power energy inside and then disconnect it from outlet. It is unnecessary to fully charge the batteries every time.
