Hi Guys and girls I hope you can help
I have a Samsung np300e5a which is not powering
we have 2 bad caps (I think) but from the caps or pdf I cant figure what they are or want to replace them with
I would be grateful for and help

I believe the components b513 b503


Photo of the damage (but it has cleaned up nice



Photo of one I did last week same model


we believe the components failed due to a load from a faulty mouse dongle on the usb

any help would be gratefully received

Re: Bad Caps Samsung NP300

There is post here that had the same story.

Apparently you didn't read and it was stated that those components are Inductors.

You can see in diagram that it's not connected to ground and makes it a inductor not a cap.

By the icon in diagram you can see it's got a coil shape.

Find a similar inductor and change it.

Check the pads and be sure are not shorted to ground.
