My external SSD drive has a led and its blinking, for sure it has power. Will check the other port as well to make sure it doesnt work on both, and report back

Hi Guys, sorry for not replying this board has been on my pile and I have some time to get back at it. I did a PRAM reset, connected an external USB boot drive and hold option, but no boot menu appears. No chime, do have a light on the external drive and a light on the USB mouse.

Hi guys i have a macbook pro early 2011 that keeps rebooting. It has been repaired before as I resoldered the legs of U7000 and C7513 has been resoldered. Board looks pretty OK though. Now it can run both ASD test EFI and OS and passes without issue, it also never reboots. Trying to boot any OS...

Unfortunately only have some donor boards lying around. Replaced all 3 IC and its been running fine now for over 3 hours, so seems to be fixed:). Thanks for the tip!

One thing i forgot to mention, before it does the shutdown, the fan starts spinning high. Thats why i initially thought its some sensor issue but ASD doesnt find any,

Yeah its a 3662, so these are the U7310, 20 and 30 correct?

Just wishful thinking, because im a noob :) PPBUS without battery is 12.57v Q7155 readings on pin 1-4 but OL on pin 5 The mac will not start, when i connect the battery no light on charger and PPBUS is 11.72v, it was stable so i didnt see it fluctuate as mentioned before.Tried it a few times...

Hello guys, i have this Late 2013 that reboots every 15 minutes to 2 hours. Cannot find anything on the logic board all very clean and ASD comes up with nothing. Are there any known issues with these boards this can relate too?

Good for holiday though :)

Hi guys i have an 820-3476 that runs off charger, orange and green light. As soon as I have the battery connected the light is off and PPBUS fluctuating between 8-4v. Did replace U7100 just because its easy :P but that didnt fix it ofcourse.Im pretty bad fixing battery related issues, some...

Got another one in today lol. Weird not many more people seems to have issues, must be the hot weather here in Thailand I guess!

Thanks bro:) you saved me my Saturday night! After replacing the missing D6910 from a 3437 working again as a new one. If you ever come to Bangkok I owe you a beer, or 2 :)!

Looks like D6910 is gone, also missing on my donor board, its like a black little cube right? Ill try what lewis recommended in another post: -> You can use D7012 from an 820-3437 or 820-00165 in a pinch but you should have donor boards and no do not use a wire!

I have this missing -> =PPDCIN_S5_CHGR_ISOL R7005 is OK, no short on pin 2, checking the rest now

Hi guys I have an 820-3462 with some small liquid damage around these components: Near Q2620 R2851 L6754 U5360 Q7220 De mac sometimes turned on but most of the time not. After replacing corroded R and clean up corrosion life was looking great. Ultrasoniced the board to get rid of the flux, and...

Kinda weird, customer comes to my office and tells me when it gets hot i get stripes. So the mac has no stripes at all, I ran Cinebench for 10 minutes and I get striped slowly getting more clear. At some point even pink bar in the display. This was a brand new display. Sending it to another shop...

Forgot to mention, I have swapped out these displays with another Mac sometime before, and it was working again which lead me thinking that the boards have some issue

Thing is, I replaced about 5-6 displays and had at least 8-10 people coming in with the same issues. Most of customer had the same issues weeks after we placed a new display. No liquid damage, no scratches nothing. So im getting very worried about replacing these display if they really fail that...

Hi Guys, just posting this out here to see if anyone of you have the same issue. Ive had already like 10-15 people come in with Macbook 12 inch, non touchbat and touchbar who get lines in the display as seen in attached pic. After replacing the display the lines are gone only for the same people...
