820-00923 no power

[Kyle93]

Arrived with liquid damage and severe damage to J9600. Data is important.

Diode mode reading on pin 4 J9600 is 0L and donar board is 0.432. Repaired all other traces on J9600

Is data still saveable if U8600 is replaced from donar board?

Check continuity between SSD_BOOT_L and SSD_BOOT_LB_L lines.

 

[Kyle93]

There is no continuity between SSD_BOOT_L and SSD_BOOT_LB_L lines. Does this need to be fixed at J9600?

 

[Kyle93]

Is it possible for this board to boot without J9600?

 

[2informaticos]

You must have continuity between all left/right pins of J9600.
If only one is bad, run wire between corresponding pads into board.

Internal SSD connects to PCH through J9600...

 

[Kyle93]

PP1V8_SUS is shorted. Removed everything but CPU but short remains.

CPU needs replacing now in order to retrieve data?

 

[Kyle93]

Can data still be retrieved even with this shorted CPU through J9600?

 

[2informaticos]

Data recovery tool exists, to recover data on this board.
Just need to connect it over J9600.

 

[Kyle93]

Which pins on J9600 need to function with continuity to retrieve data with tool? I already have the tool

 

[2informaticos]

All pins from the right side (regarding of schematic) connect to the tool.

 

[Kyle93]

No response on tool. All pins have continuity now but pin 4 SSD_BOOT_LB_L is 0.77 diode and on donar is 427. Is this bad U8600?

 

[2informaticos]

May have chip issue, or bad solder.

 

[Kyle93]

Trying to replace U8600 pad 315 PP1V8_SSD_HOT is missing however all other pads are present after cleanup. Will replacement U8600 still work for data recovery with this pad missing?

 

[2informaticos]

The other pads should support 1V8_SSD_HOT power rail.

 

[Kyle93]

To save trouble of replacing U8600 would the data be readable or even boot into the OS if U9120/U9200/U9100 were moved and soldered to a working 820-00923 board since these have the T1 chip?
