Do you re-ball with lead solder. Do you remove all edge bonding from VRAM. Do you use profiles or use your own sense. Don't buy these 2012 battered chips. I would not trust them to work even though they are likely genuine, they have had a hard life. I did buy one of these chips. It was the...

So it's working from the iGPU once external is plugged and unplugged. It's working from the GPU when monitor is plugged. It does fuck all when booted with only internal screen is in use unless monitor is plugged and unplugged. So what is telling the output to wake up?

iGPU I guess but.... Hmm, now in OS X if I plug in a mini display cable the internal screen wakes up. Internal will stay working if external is removed. Restart with internal only and back to the no output until I plug external display again. Start the machine up with external plugged in and...

SMC can and does fail without liquid.... I am not saying that is the problem, just that they DO fail.

I noticed you listed voltages for S0 rails... but..... No S5_PWRGD = no ADAPTOR_EN = no SLP_S5 There is no point looking at anything (power state wise) above 3.42V - 8.6V and S5 rails

Duke will be able to tell you that one but... The fact that they are old and battered, might be an issue. Are you re-balling them with lead solder? Using a profile or eye? Removing all edge bonding from VRAM?

That's from SEE-IC right? I have no idea where these things are made but the chip is probably genuine. The story is it's been knocking about for a few years and probably kicked accross the floor a few times. I have been told that some litttle china man just found these somehwre forgotten about...

Hi. Got a board here that was liquid damaged. U9000 was shorted, replaced U9000 and caps. Screen-side eDP connector was totally fucked so replaced also (screen now works perfect on this and another machine). Replaced J9000 Replaced U9100 Replaced R9018 Touched up U8900 with the iron too. This...

Good Point.

Not a chance. Think I'll just refuse them.

Had a couple of bords come back after replacing C9560. Replaced with larger non tant caps 2v 330uF but still getting shutdowns.... They are from donor boards though.

Bad RAM being the actual chips or possible the balls?

Probably smuggled under some little China man's hat. Find the China man, lift his hat!.. Man that would be a game. The idea of the game is to grab random China men from the crowd and see if you can get enough good chips without getting ripped off so you can make some money. If you make money...

Aside from the liquid.... Have hou tried checking if the EFI is OK? Slap a donor chip on there ONLY to test that it will chime and show you boot menu for a while. Had one similar the other day.

No Title I put a 0001 on it. See image for VBIOS

Sure it's interesting, I just don't have time for interesting. 1x wife, 1x 15 yr old, 6x cats, 3x dogs, a car a house and my own business with zero staff since everyone I employ is a useless cunt. Where's the tme man :(. If learning is advantageous then sure there is time. This is single case...

Thing is, who cares really. It's not as if doing BGA jobs on these 2011 / 10s is going to last very much longer. These are 7 / 8 year old machnes now. Some china man has to smuggle chips out the factory under his hat, then get them acccross boarders, and who the fuck knows if in 2018 they will...

Thank you.

I honestly have no idea. You're probably in a better possition to figure out why... Maybe VBIOS?? Chips are Samsung K4G20325FC-HC04 1GB I had to install R8610 to get the 005 to work at all. I can run FurMark and no issues. Use as normal without issues... ... Just, no problems at all. I have...

Well depending on what chips I order and where from I'm payng between £4 and £12 more. Even though the three people I buy from are all sourcing from what I beleive is the same chinese guys, I think the extra cash is probably worth it for knowing they are good chips and not having to buy by the...
