    Asus X555LD No Charge

    Hello,

    I have a Asus X555LD that does not show any life at all. It is only 1 year old and had very little use. I have looked at the motherboard for any idication to any bad components (only a visual look) but on looking I noticed a chip that had 2 pins soldered together.

    I have attached an image of the chip. The markings are 4955N RAX90, this flags up as 'Power MOSFET'.

    Should these pins be joined? It looks well joined to be honest I just thought it was strange.

    Yes, that's normal. It's a 3+1 on one side, 4 on the other. The single pin on the right is the gate of the MOSFET.

      Ah I'm not so lucky then .

      Is it easy to investigate the board or is it not worth doing?
