Share HD Pics of both Sides of the Motherboard. You made Sure, the Adapter is working properly? I believe, we have to Work without Schematics Here.

Hi,

Could you tell part number on the ic next to the speaker connector (2nd picture)? I have a board with damaged chip and can't find what that is. Also some of the resistors above it are broken, would appreciate if you could tell resistance of those.

Maybe someone had better luck finding schematic / boardview for this model?

Do you have a USB-C ammeter to check current draw and voltage? You can also try checking if you have 3.3V present on power button.

If it is similar to apple board, most likely there will be a chip for the USB-C to negotiate voltage. You could also have a frozen/corrupt BIOS.

PS; Try using font color and size that will contrast well with your picture.

Hp spectre x360 no power help!

Hi all,

I have the above laptop, motherboard is DA0X36MBAE0 REV:E which does not have power. it is using USB type C for power.

I plugged in Hp adaptor and also power pack but i do not getting any voltages anywhere.
i removed usb type c connector from board to see if there is any problem with the board, one of them traces are missing (main one at the corner) and the second one looks good but when i tried to install it back IS NOT SETTING ALL THE WAY DOWN ON THE BOARD and i thing it does not make good contact with the board that is why i do not have any power (that is my opinion).
i tried to find the part from ebay part #181106 but there is nothing..
I measured for short on TPS65988 charging ic and there is no short..

Does anyone can Help!!!

Thanks
