Laptop Adapter Light Turns Off When Plugged In

Laptop Adapter Light Turns Off When Plugged In. A list of devices will appear. I have tried many ways to get around this issue, 1 being cleaning the insides and adding a new thermal paste coat (reduced the temp by 10c or so).

I did took it apart and look for some problem around. Right click the desktop anywhere that its blank and choose properties from the menu that comes up. The problem is the power management on the mother board is defective.

But when i plug any* power adapter into this specific optiplex, the light on the adapter immediately goes out. My inspirion 13 7000s series laptop stopped charging. I saw the threads about the motherboard might be faulty.

It Could Be Set To Turn Off When Power Cord Plugged In.


As soon as i tried to plug it back into the computer, however, the blue light immediately turns off. Click "manage," then "device manager." step 3: Other adapters do the exact same thing.

In The Window, Click The Screen Saver.


*poof* (though without an actual noise. The problem is the power management on the mother board is defective. The laptop power supply light goes off when plugged in

It Involves The Power Adapter Light Going Out When It Is Plugged Into The Laptop.


I cannot start the computer without the adapter as the battery is dead. In some laptops, a blinking light means that the charger is charging the battery. The fact that the light on the charger turns off whenever you plug it in to the laptop indicates that the problem is most certainly an electrical issue.

Eventually The Blue Light Came Back On The Cord After I Plugged It In.


If the battery has stopped charging and the manual hasn't said anything about a blinking light when the battery is charging, you may have a short on the motherboard that keeps forcing the charger to shut down. I noticed this problem when the laptop charge has reached more than 90%. When first time same problem (adaptor green light goes off when connected to laptop) happened, i guessed its some kind of short circuit inside laptop.
