Just left it in the exact configuration you requested for 5 minutes, nothing.
I agree, I haven't seen this behavior before on this model AND had correct vcore, not sure what to think.
PLT_RST_L goes high as soon as the USB-C ammeter jumps up to 20V, and remains high indefinitely.
I've already done so, the board hangs at 20V 0.4A after a few seconds, no activity on anything connected. Do I need to leave it for a significant period of time (more than a few minutes) for this test?
Got a replacement TL866II PLUS programmer, much easier to use when it's not defective.
First I followed the instructions below to clean my ME region, no changes observed afterwards
Then I flashed this BIOS image with a clean ME region that I...
This whole BIOS programming thing is going to make me loose my mind.
I bought the TL866II PLUS
And a WSON8 adapter board
And got the official software from Xgpro, plugged in the device, successfully...
No blinking light activity on a thumb drive or external SSD.
No external video output.
External video test procedure: Place board in housing for hall effect sensors, with no flexes connected, connect USB-C power and USB-C to HDMI adapter while the lid is open, wait 30 seconds, close lid, image...
Board hangs at 20V 0.4A after a few seconds indefinitely, or 0.5A when installed in the chassis with only the battery disconnected. All major power rails are present, trackpad clicks, no light on caps lock, no response on display. No signs of liquid damage.
I'm often unsure where to start...
I hear you... If I transplant the T2 from the donor board, could that theoretically work?
I see so many of these newer boards dead in the water and would like to raise the repair rate even if it takes throwing in some time and practice at NAND and T2 swaps, in particular this board is work...
Unfortunately I'm stuck in DFU after the NAND transplant, here's what I did:
-Verified that no NAND power rails were shorted on the donor board
-Replaced U9080 on the customer board, verified that all NAND voltages were now stable
-Moved 6x NANDs from an identical donor board with the same size...
