MS-16R61 Rev 2.0 EC not responding after repacement

[questore]

Hello adventurers

I have this board and it came from a friend with a shorted EC.
I have ordered a new one and replaced it.
Now i have 4 Milliamps draw on pluging
3VALW and 5VALW present (i know nothing about RSMRST and ECRST because web only has boardview for 16r3 and this modell looks competly different)
For EC flash i need KSO3 KSI4 KSI7 KSI6 KSI5. These are all 3.3v EXCEPT KSO3 is 2.2V
I have checked the FFC cable connections and they are OK.
I have removed and Reballed the IC again, but no change.
Do you have idea why EC not responding...

Good day, everyone! Can anyone please share a board layout (complete with components, test points, etc.) of iPad Pro 10.5 (Model : A1709)? There is already a schematic diagram of iPad Pro 10.5 here but somehow it lacks the complete board layout. I need to know where the specific Test Points (TP) are on the motherboard. I hope someone can help me.

Hi all forum members,

Few days ago, i might have forgotten to close my home fridge freezer door completely. The next day, the ice cubes and frozen meat almost melted halfway and the freezer doesn't feel cool. I shut it off, wipe dry and let it air dry for one whole day. The next day i switched on the fridge, the compressor run for a second and it shuts off(no vibration and no sound at all) only the internal freezer compartment fan is running but is not cooling even i switched on a full day.
After shut off, i dismantle the rear water pan holder and reached to the compressor wiring....

Hi all
I have one of those machines. Clevo PC70DP.

Machine starts, but turns off quite quick. Just before turning off one can hear fans are spinning at high speed. Can be turned back on again right away.
So, feels like overheat problem.
I cleaned up fans and heatsinks and replaced thermal paste. I can now see CPU runs cooler and machine stays on for longer, but still same.

Few more findings:
1. on-board NVIDIA card is not found. Not showing up in Windows or in BIOS.
2. I tried to run CPU stress test. CPU stays at about 65 degrees. Works...

Hi all,

title says it all. I have Airpods Max which no charing light. Reset lights show up when i connect a USB charger and push the buttons but not loading or bluetooth reaction. USB meter shows 5v, 0,6a and 1,8-3,2w (differs on used charger).
The videos i found about repairs are more something like a try and error with changing parts or battery replacement but no direct fault analysis.
So maybe anybody here has experience in repairs or can help me to locate the problem? My stomach tells me that i need a new battery but 50€ for a feeling is too much.

Hello everyone,

I need the EC firmware dump for Dell Latitude 5420, motherboard GDF40 LA-K491P Rev 3.0 (A02).

The embedded controller is MEC5107-LJ (UE1).

The EC flash chip is W25Q80DV, 8Mbit (1MB).

I already have the 32MB BIOS dump (W25Q256JV), but my system is still not powering on — just amber blink. I suspect the EC firmware is missing or corrupted.

If anyone has this board and can share their EC dump from the 25Q80DV, I’d be very grateful.

Thank you in advance!...
