I know that installing MacOS "SHOULD" initiate a mid-setup prompt that a board is enrolled in DEP, and if it doesn't, it will "usually" pop up in MacOS post-install in the top-right corner of the screen. However, I've had some boards recently that show no notifications of DEP, and a few days...

Yeah it's your LP8550. It's annoying, but not a "problem". Just not as smooth and buttery.

Cheapest is from China via eBay/Ali/etc. You can get most models for <$20.00/each that way. Best way is of course accumulation from previous duds/no-fix boards, etc.

This isn't as easy to Google as expected; but I feel like I recall a customer mentioning the 2018+ Touchbar TouchID buttons (not Airs) are programmable or re-pairable. I feel like a customer mentioned that Apple told them their TouchID button wasn't re-pairable, "because it's not a 2018 or 2019...

Yeah I don't know why people say to leave U3900 alone; I've replaced dozens of them and it DOES fix the camera issue 95% of the time (assuming no damage elsewhere, connector is good, etc). It's not hard at all. You can find stencils all over for it; search chip part# and you'll find it. I don't...

Hey Guys! I just saw these replies; I think the funky forum migrations made me overlook them all. PLEASE MESSAGE ME DIRECTLY AND I'LL REPLY BACK TO YOU. Thanks!

AWESOME--thanks so much, PE!

I've seen it referenced a few times on here that the T2 units can suffer from corrupted/damaged T2 firmware, which can be updated via DFU mode using a process. I did see where it was mentioned to "search the forum for recent topics...", but didn't find anything useful when doing so. It also...

This is all kinds of shady. If the laptop is not stolen, all you have to do is call up Epsilon and explain that you purchased a decommissioned laptop from an eCycler that is still tied to their Remote Management account. This is ALL based on serial number, so you aren't going to bypass it by...

TCRS, are you using FDM6708s or 6808s? Replacing only the power supplies or controller as well? The way we test is to let the unit sleep overnight (6+ hours). If CPU is damaged/bad, it usually either won't wake from sleep (most common--LCD stays black, etc), or will wake/crash instantly. I've...

Man, I'd say don't waste your time. This "fix" works minimally at best, and the issue recurs after a very short time. IF you insist on this repair, do it ONLY on 3662/00138 boards. The DG boards just do not like this repair, and don't seem to "take" the repair around 90% of the time. The IG...

Yep exactly. The "short" isn't really there. Just error from instrumentation and discharge. OP ignore it.

Guys, he's obviously checking for a short IMMEDIATELY after powering off the board. OP, let the board discharge for 2-3 minutes and then check for short on ppbus. It will show a short if you check it immediately after removing power. If it shows a short, then check again after 30 seconds. Keep...

Using genuine 85W magsafe2 charger, yeah; tried 3 different ones. I just bridged pins 4/5 of U7000 and no change. :( I will check system report and report back soon; I might throw another SMC on there to be sure. I did pull from a parts board, so who knows. Would be wild if it had the exact...

Yes :( Thinking a PCB issue at this point. Literally everything else works except charging and green light. Board runs from charger, and will run from charged battery. All functions normal, but no green light and no charging ("battery is not charging"). All signals present and normal; ONEWIRE...

Yeah, tried about a dozen. No luck. Thinking this one might be a PCB fault, but no cracks or damage visible. Might go ahead and call it quits on this one in the interest of time.

Got one that has me stumped; first one in a while of this type! 1. 820-00138, no liquid, no damage from aftermarket charger or anything at all. Board powers on and boots, but has no green light. 2. Confirmed SMC_BC_ACOK, SYS_ONEWIRE, 3v42, etc, are all present across board and near SMC. 3...

I have an 820-00923 with a few different symptoms that I believe "might" be caused by a bad SMC. Basically, it either won't wake from sleep, or takes a very, very long time. Additionally, the power button TouchID and SMC reset functions work, but the button will not turn the board/unit on or...

Dead CPU, RIP.
