    820-3437 no camera u3900

    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...

    T2 firmware update process?

    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...

    Remote management Issue

    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...

    820-3787 CPU FETs, what are the number of the pieces to replace

    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...

    820-3787 CPU FETs, what are the number of the pieces to replace

    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...

    820-00840 5v not turning on

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

    820-00840 5v not turning on

    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...

    820-00138 Powers and boots, but no green light.

    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...

    820-00138 Powers and boots, but no green light.

    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...

    820-00138 Powers and boots, but no green light.

    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.

    820-00138 Powers and boots, but no green light.

    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...

    820-00923 Takes a looooong time to wake from sleep?

    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...

    Tons of untouched/clean boards for sale!

    Also, to clarify: These are not "parts" boards. These are boards with a very high chance of repair, not ones we've picked through and discarded. These are directly from our stock of repairable boards.

    Tons of untouched/clean boards for sale!

    We could arrange international shipping, but would ask you to cover the costs. These boards can get heavy when we ship 50+, so the cost is likely to be quite high. I'll try to PM you now--thanks!

    Tons of untouched/clean boards for sale!

    We have too many boards! We have inventory that's dying on the vine because we simply don't have the time or manpower to repair them all. In addition, we're also rolling over stock and clearing out some older model boards. Before we slaved away to get them all listed on eBay or sold to our...

    A1706 - Critical software update

    Make sure your trackpad and trackpad cable are both working and not gunked up. These units will boot to the software update if there's a problem with the trackpad, FYI.
