When a SONY SGPAC10V1 laptop power AC adapter
is plugged in to a laptop and the laptop is turned on, you will notice
the adapter may be warm to the touch. The more the laptop gets used, the
warmer the AC adapter may become. A relatively warm power adapter is normal, especially when the laptop is being used and the battery is being charged.
However, if the SONY SGPAC10V1 Adapter Charger
is quite hot, that it could hurt your hand after touching it for just a
few seconds, this is a potential problem. Sometimes the heat coming out
is so powerful that it even melts the casing itself in case of chargers
or melts the things we keep closer to it. We less often care about heat
comes from charging adapters
than from the machine itself. While the laptop temperature depends on
the workload, battery type, and the cooling measures of the design,
overheating of laptop chargers
are also related to these factors. An adapter that hot is a warning
sign that something could be wrong with the adapter or the laptop.
Before we try to fix the overheating of chargers, we need to know why it is getting overly heated. We’ll discuss some of the aspects where chargers can be overheated.Laptop chargers consist of an electronic circuit that converts analog current into direct current of suitable power and voltage. It involves rectification, switching and filtering which are done by diodes and semiconductor IC’s. The switching IC’s or transistors are the most heating parts as they handle most power. The whole circuit board is usually enclosed in a plastic casing generally with no ventilation or cooling fans. This is why chargers tend to heat even at low workloads. There are many reasons why a charging SMPS adapter overheats:
Some laptop comes with batteries that draw too much current to charge. If the charging current is greater than the rated current of the charger, there is a risk that you will burn the charger and battery. It’s better to replace your battery if this is the case. In order to verify that the battery is causing the problem, remove the battery from the Notebook and power on the notebook with charger plugged in. If it behaves normally, problem is with the battery.
CHECK ADAPTER
The first thing to check is whether the laptop battery is gaining any charge with the adapter plugged into an outlet. If it is, then the issue is most likely with the AC adapter itself. If the battery is not charging, there could be an issue with the power connection in the laptop, as well as the SONY SGPAC10V1 adapter.
Also,
check the end of the adapter cord that connects to the laptop, as well
as the power connection on the SONY laptop, for any possible damage.
This damage may include a bent pin inside the connector or bend/break
marks in the metal jacket of the connector. If you notice any damage,
replace the SONY SGPAC10V1 adapter or have the laptop repaired.
If you notice the SONY SGPAC10V1 Adapter is very hot, turn off your computer and unplug the power adapter
from the wall outlet. Let it cool down completely, then plug it back in
to the wall outlet and turn on the laptop. Monitor the temperature of
the adapter for a while and if it becomes hot again, take the laptop and
power adapter to a computer repair shop and have them check it. An
issue like this is not something you want to ignore, as it could cause
serious damage to a laptop or even potentially start a fire.
What to Do
Replacing the Charger
If your SONY SGPAC10V1 charger ever
becomes so hot that it can melt other items, is too hot to hold or
becomes a fire risk, it's time to replace your charger. With regular
use, chargers -- like other electronic devices -- wear away certain
components, which results in malfunction. If the charger or
transformer becomes too hot and malfunctions, it could result in excess
voltage ruining your laptop. Since you don't want a chargermalfunction
to affect your laptop, it's best to disconnect an excessively
heated charger and bring it to a computer repair store for evaluation
and possible replacement.
REPLACED BATTERY
If your laptop charger is heating up during charging after replacing the battery, the battery must be of a different rating. It happens sometimes that batteries of same serial number is manufactured with different rating. For Eg, the SONY SGPAC10V1 battery is available asSONY SGPAC10V1 Long Life Notebook Battery with extended backup. This might draw excess current than rated current of SONY SGPAC10V1 charger which would cause overheating.Additionally, if you have melting the charger tip specifically, it should be a problem of high resistance caused by poor connection between the charging socket/port and the charger pin. If you have any dirt or corrosion on the pin of the charger, try to clean it up. If it doesn’t work, you can get your SONY SGPAC10V1 charger pin or tip replaced without costing too much.
If you have checked all the above things, and your laptop charger keeps overheating, it is time for you to consult a technician.
