Re: faulty smd - can be identify ?

thank you so much for your support. the smd is from a Turbo-X laptop. for the motherboard you can see the photo. i dont know more about this motherboard.
it was given to me from a friend as not working.
i google also for the schematic of this motherboard but the only thing i can find is some bios files. can anyone help also for the schematic?

thank you again for your great support.

Schematic requests go here: https://www.badcaps.net/forum/forumdisplay.php?f=41 .Don`t bother requesting it though,as its not available.

The board is a Pegatron D15D .Look at the Typical Application Circuit in the richtek datasheet,look for the four high side and low side mosfets on the board and test those.Before replacing the IC check the resistance to gnd for short on pins 3,8,13,18 after the old one is desoldered.

Can someone identify that component for me and what measurement does it have? Thank you

The pads and placement look like bulk caps.

The larger PCB track area = GROUND.

The other side of these pads = probably a power rail.

Check the voltage of that power rail and suspecting it to be 3v3 or 5v0.

Based on this assumption, you can place bulk caps onboard rated for the peak voltage of 6v3 and capacitance that is available to you - perhaps 22uf / 47uf for each. Need to confirm the body size of the pads so we can confirm if it is 1206 (appears to be) - perhaps were tantalum style but ceramic caps will be fine here.

Start with the voltage check.
