Haha, OK... NP. The Green Dot.? It was the Green Dot wasn't it? I vaugly remember this in another post. Lol. Take care man.

Its original... Since the hot air seems to fix it for like a day, shouldnt it be something around there? I didn't want to just start switching components blind to fix it. I would rather track it down and know exactly what it is. https://photos.app.goo.gl/iGF5vurGniLQUgJT6 Thanks Duke. Take care.

No liquid. This board has G3H PP3V42, S5 Rails, but wont always go into S3. I find that when Im missing S3 that PM_SLP_S4_L is missing as well. If I heat area around 7201 with hot air, I get all power rails back and machine boots. I have replaced U7201 thinking that it was shorting PM_SLP to...

Yes, I have 1.65V on CPU Vcore. Will check other recommendations. Thanks guys.

Hi. This board has liquid damage on C6412 with damage also on C6432. The fan will spin up 3 times before staying on when power is applied. Also I have 1.65V on CPUVCORE. No display. Missing EDP_PANEL_PWR_OR_PSR_EN on pin 1 R8319. PP5VS4 is present. Checked U8330 and I have PP3V3_S0 on pin 8...

Sorry. I forgot to mention that I have replaced the cable with 821-00184. Trackpad works. External KB works. More concerned with booting issues. also will not chime due to no audio. Internal KB shows in Sys Report. Only power button working. This with new KB and connector. Thanks Duke!

Ok Thanks a lot.

Was liquid damage around ISL, KB connector and SMC. All that as been replaced. It will now turn on and boot, but is very slow to display LCD and will only eventually display LCD and boot with an SSD or via USB is installed. Without a drive attached it will turn on, fans spin but screen will...

I have this board that boots, chimes and PRAM's. It will boot to white screen and never give ? or search for other boot devices when holding down "option" key. Also cannot boot to recovery. I have already tried another BIOS from a known working board for testing. I am aware that this will most...

Hey Duke! The display on his computer randomly will freeze with have a checker like grid on it. Becomes totally unresponsive. History - I know that the display was recently replaced by Apple for a blueish line across it. Thank you.

Does anyone have access to this? Thanks in advance.

dukefawks Inwerp Sector errors when hooked via USB adapter to PC running HD Tune. https://photos.app.goo.gl/XXqigPwwqYZorZ773 Like I said this is the third hard drive I have changed for this customer in a years time and I am getting suspicious of what could be the cause. :confused: So I...

Hey man thanks for the response. Switched RAM on both slots... Same outcome. :(

Another 2011 A1286 that will shut down as soon as Apple logo appears when internal or external HDD is attached. This is on battery only and internal HDD unplugged. https://photos.app.goo.gl/sdYpveMtFoRYMOqV2 When on charger only and internal HDD unplugged it wont even make it to chime. This...

I have a 2011 A1286 that is back for the 3rd time due to hard drive failure. Partition is unrecoverable. I have tried EasUS and Disk Drill so far. My question is, is it possible for a board or cable to be causing this recurring problem? I have replaced the drive 3 times like i said. Thanks for...

Hi.820-2915, no liquid. Would power up then shut down almost instantly. Found that cPU_Vcore was missing and U7400 wasnt putting out voltage to FETs. I replaced U7400 and all HS FETS. After this, computer booted into OS. Then I checked VCORE and found it was fluctuating between .75V and 1.1V...

jamiehorn1 At the time when I replaced R7121/22 I was getting 3 Ohms on R7151/52, so I figured everything was OK on the battery side. Shortly after my post, R7121/22 went out again. This time R7151/52 went out as well. Replaced everything again including R7150, R7120 and transistors on Batt...

Hi- Customer was using aftermarket charger. Was 3.42 on PPBUS. Bad magsafe i/o board, R7122, R7121 and ISL. Replaced all said components, and now have 12.56V and a booting machine. The problem is when both battery and charger are plugged in, the light on the charger goes dead and computer no...
