Like all the electronic devices, eventually laptop ac adapters will
stop working too. There are lots of causes from exposure to the extreme
temperatures, excessive wire bending, or simply that it is the aging adapter.
Unluckily, there is no sure amount of time which adapters may last. Their
lifespan is relying on how much they are used. Below I will list several ways
of checking wither your adapter has already ceased working.
Check Your laptop
Your laptop ac adapter may not get your notebook powered due to the
loose connector. Make sure that all connectors are correctly inserted. Check
the ac adapter box too. usually the laptop ac adapters have an LED light which
lights up when the adapter is supplying power to the laptop. If the light is
off, then your laptop should not receive any power.
After you have already checked all the connectors of your adapter,
have a look at electrical outlet. The problem may merely be that power socket
which you are connected is not working anymore. Change the sockets to solve
this issue. For the DC AC adapter of your laptop, check the DC-jack. This
adapter must snugly fit. If you can get your adapter plugged in only the right
angle or spot, then the DC-jack could be broken.(HP Pavilion dv4 Laptop Battery)
Check the Adapter
A bent cable could be the culprit of the malfunctioning AC adapter.
Think about this just like a garden hose. And if you bend or pinch a garden
hose when it is running water, so the water are not able to exit the hose. An
AC adapter will work in the similar basic way.
Make certain nothing is resting on the power cable like notebook
bag, a book, or anything else that may pinch your adapter cable. If nothing may
bend the cable, then check the cable itself. So, the consistent bending from
storing the adapter might expose the wires within the cable. This exposure may
cause it to stop working properly.(HP Elitebook 8730w Laptop Battery)
