Interesting! At face value, it does look like RD560 is open or high resistance (or corroded underneath). It's a 50 milliohm 1/3W current sense resistor, can't say I've ever seen a CSR actually fail, but then that's just me.

There are plenty of these resistors on older boards (search for 107S00017 in FlexBV shows many models have it). So if you have some old T1 or T2 boards you should be able to locate a donor. Failing that, closest I found was one from LittleFuse (P/N: L4CC0306QLR050FNR). Available from Mouser or Digikey....

Thanks Flea, I think you are on the money. There appears to be an A and B variant from SUHMS for this. No publicly available datasheet for it unfortunately. Did a search in FlexBV and found it in the Lenovo 203013-1 schematic amongst others. Appears to be for the VCCIN_AUX rail in that one.

CPU was shorted anyway.

Have a 440 G8 fitted with a DAX8QAMB8D0 REV D motherboard. One IC is cracked down the middle, and I suspect this is probably the system agent rail for the CPU. It's dead short, but just wanted to know what IC this is before I take it off. Highly likely CPU is shorted but anyway.

I think the markings (as best as I can make them) are

MPM3
2941
B381

I wiped it with IPA but the first two numbers of the 2nd row disappeared.

Edit: Took the IC off, CPU is shorted. I guess it was driven too hard, failed then 19V straight into the CPU. No...

I ended up ordering a 2SJ3072-190111F connector off Aliexpress. It's electrically the same, with same pin footprint, just slightly different dimensions. It still fit perfectly in the chassis and also worked with headphones as well.

BTW, thank you so much for the schematic!! I'd have never found this part if I didn't get the original part number from the schematic.

Thanks Flea. I had modified U366 with another dump prior to finding the leaky cap (thinking it was an EC update failure). Once the cap was replaced, the laptop booted up, however reported an Endpoint Security failure. I did try a downgrade to V1.30 to reflash but it bricked the machine. Restoring both my original dumps resolved that so messing with the EC bios you will get this problem.

The primary fault was the leaky cap on P3V3_RTC pulling it down to 0.75V. It measured 12 ohms initially, but went full short when I injected 3V onto it....

Not sure what the go is with this one. I had left it doing final Windows 11 updates, when I came back to it later had high fan spin and forcibly turned it off with power button. Not sure if this was a bad Windows F/W update or not. Now all I get is 7 orange blinks on the battery light when the power is applied either via barrel adaptor or USB-C. This doesn't seem to line up with anything in the manual. AFAIK, it was already on V1.31 BIOS which is supposed to be the latest.

One other weird thing is it is flattening the BIOS battery after I just have replaced it but I think that is...

You can remove it yourself.

I'm after the audio jack for the audio sub-board 6-71-NH5S8-D01 (AJ-HP-COMBO1). Existing one is broken after a fall. Part number is a Singatron 2SJ3072-112111F. Just cannot find a distributor for it.

Anyone know of a distributor for Singatron connectors? Taiwanese laptops are so frustrating to find parts for!
