I’m not sure it’s not in me :/ I’m just trying to resolve all issues before it leaves so they have nothing to complain about. I found the usb issue it was d4600 along with 3 vias that I ran jumpers to. All I have left is the chime so if I solve it I will post it here so maybe it can help someone...

I forgot to ask. why is it not chiming ? Is it disable in nvram? Wouldn’t a PRAM reset it?

ok I will thanks

I checked them they’re all good. But I’ll go over them again. I also checked each pin individually for connection to ram. May I ask you can a question? I see their are several phases of the cpu is it at all possible that it not passing the data integrity because the cpu isn’t at the proper state...

ok will do thanks

Well I got the programmer and well 2 things I don’t know how to use it :/ and another bios does with the same numerations Also had 3 beeps :/ I guess it time to check all the power lines again :( if you come up with anything let me know I’ll be tracing from the ram to see what’s going on and out :/

Ok i was wrong it was booting I just had no chime. Weird thing is I just have no chime but the audio does work When it boot into OS X the audio works :/ . I’m not sure why I don’t get a chime I tried PRAM a few time and nothing. all I have left it to resolve no WiFi hardware installed and 1 usb...

Thank you very much

Thank you. You are always a great help :) I recurved the programmer on Monday-Wednesday I’ll let you know how it goes Thanks once again

Ok. 1-What would be the right usb mouse solid light ? I just wanna know for next time. 2- Also after a newer gpu “2017” is swapped and the client wanted the underfill replaced I was gonna use Loctite 3513. Because High temp silicone smells Strong so I’m hoping 3513 is better. Do you have a...

I did the one you told me to order. All lights illuminated. There like 5-6 leds that are brighter than others. :/ I also ordered a t866ii programmer to try a new clean bios. Do you know where I can find Both Versions? these boards can from a repair shop and aren’t in good shape :(

Someone had previously remove and mount it sideways I just removed it and placed correctly but it was shorted. So I took it off.. Yes blinking mouse and blinking usb stick

Ok so I removed the gpu and i have no chime. I checked the tona resistor r7402 12.55v and it’s 91k. Ppvcore_s0_cpu ph1,2,3 .78-.9v PPVCORE_so_axg_L=.458v Cpuimvp_boot1G=4.7v is this right ?

Hi I have another one of these. I’m getting 3 beeps. Fan is spinning and I checked u7300 enable signals and output at L7330 on pin 2 I have 1.5v. With no ram present it beeps once every second with ram installed it beeps 3 times. I tried 3 different modules. So I need some help

I’ll Iook in to a pre heater thanks.I just hesitant as I wasn’t sure if it was mux or not. It’s getting Burning hot so I’m assuming it’s internally shorted. I’ll pull and if it isn’t I’ll re-ball it. I’m also stuck on a short in this board. :(

Hi I have a question let’s say I have to remove a gpu and replace it . I have a quick station and do it by hand. Is it worth getting a bga rework station. I’ve done 3 Gpu in various boards so far and well it’s a little nerve racking. I was gonna attempt a mux replacement on but I’m not sure I...

I got it :) Q5501 and yes it’s all working now Thank you so much for your help

I’m checking r5271, r5270 and r5260, r5262, and the Vias for continuity. it’s booting quickly and just buggy with trackpad and fan speed I’m gonna see if I find the asd efi for this board to help me narrow it down

Ok so let me ask you this if I boot in to OS X and the fan spins high all the time with an erratic mouse, keyboard is a little laggy . Is it most likely a heat sensor issue? I was guessing maybe it can’t sense the temp and runs it at high to compensate?

I want to thank you for taking the time out to help me. it actually turned out to be just a faulty connector that was installed. It’s all good now
