How long should it take for the “ME” to finish its process of getting “reacquainted” with hardware? I waited like 2 mins is this enough For the machine to boot? Sometimes I notice longer wait times than others

Thank you @piernov I will test this file as well

Ok I will try to writ it again @2informaticos

Unfortunately that didn’t work :( it also does nothing. But I removed the bios from the 820-3115 board awaiting pch and that bios chimes on this board but has no video :( so I guess I’ll just keep looking for another bios thank you 2informatico

Thank you very much. Do you happen to have one for 820-2850? That’s all I will need. If possible that would be great

Hi I purchased a board off eBay and I repaired the water damaged areas. but it has no bios chip I’d like to do a clean ME and switch serial# from a donor chip. I searched on this forum but all the “clean” or “test” bios say “in owners trash” or just don’t download. I wanted to use ME injector...

So I’m guessing cpu data lines are in short either another pch or cpu :(. Is this another “donor board” for the stock pile ?

Ok on ddr test module all are brightly lite except DQ14 I traced it back. it looks like it’s coupled with PP1v05_S0GPU but many are connected to the same line. In the manual which is Chinese :/ Ok I just re-read it “All must have the same brightness: a too dark diode can signal an open circuit...

Yes I have a ddr test module I will try it. thanks for the suggestion. I tried ddr 8500 and 10666 one slot at a time same results

Hi I have a board that I purchased it wasn’t turning on it had r5281, r5280 that where 2k each I replaced them with 1k and now I get a orange light. I also replaced c9560 as usual and I get a fan spin but no chime or video. When I remove the ram it does beep. With The usb mouse flashes about...

Thank you very much I have two different cameras and both don’t work. I’ll search for it :) wish me luck cause I need it

Ok yes als works I cover camera and key board lights intensify. I tried also re installing OS X and even erase ssd several time. Just in case it was a software issue :( I’m basically stuck.

Ok I’ll check it. I used around 380 to solder it and it’s the same symptoms as before :/ all inputs and no change on output

I’ve come back to this board once again I replaced BCM U3900 chip cleaned me region and nothing :( I resoldered the camera connector. Is it possible that I can send the file for bios and maybe you can clean the me :/ I’ve tried but maybe I’m not doing it right. I’ll go over the pier rails again...

Ok thank you 2informatico. May I ask one more question. Would it be better to invest in a ultrasonic or a bga machines? I have purchased at least 6 boards that either have pch or cpu issues. It’s more about trying to rescue what you can. Is it a wise investment ?

Do you think it’s worth checking CLKE0, CLKE1 or DMI connections for some sort of Signals or wave forms ? Or just call it quits ? Also thank you for your help

Yes I tested each slot individually both have same issue 1beep with out ram stick and 3 beeps with ram installed Both ram slots pass ram with DDR test card. All DDR test card illuminate

Hi I got yet another board that does 3 beeps I missing u7300 missing 19&20 But it seems I have all other signals. with ram installed Smbus is good I have 1 beep with ram removed. All measurements with ram installed 12800& 10666 tested with both 1-DDRREG_VTTSNS=.75 2-PP1v5_S3=1.5v...

Hi, @piernov thank you for you help :( honestly I’m gonna Use a modified digital cook top So I’m guessing it’s not classified as “decent” and I have a hozan bga hot air from the top. I also have a Quick 861On my desk. I see you’ve already answered my question About buying a new PCH above so...

Hi, I just wanted to recap. I wanted to find the exact reason why I wasn’t getting all my signals for lvds. I’m not sure this is correct but on pin 458 of u1800 I have a dead 0.00v short I removed (R2465, R2460, C2465,C2466,C7781,u7800) on this line and on u7800 Pin 1 (PP1V05_S0_PCH_VCCADPLL) I...
