A2141 - 820-01700 no power

[hgoncalves]

Hi.

I have an A2141 - 820-01700 with no power, with only 20V on ampmetter.

I've no history of it (just stoped working client say) and nothing seams oxidated on motherboard.

PP2V5_NAND_SSD0 is shorted.

After removing U9580 and L9580, PP2V5_NAND_SSD is still shorted and nothing heats on infrared camera with 2.7V.

PP2V5_NAND_SSD is 0.045 on diode reading and 39 ohm to ground.

Can something else be shorting PP2V5_NAND_SSD that's escaping me?

Can you help?

Not pure short, so no easy to heat anything with low voltage.
You can try with 3V, using a performant thermal camera.
May need to wait few minutes, to detect few degrees differences.
