    Three 820-01700 32GB Logic Boards Same Issue: Won't Wake From Hibernate
    by ugamazing
    I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!

    We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre...

    Apple M1 Boards & Exclamatory Error?
    by ugamazing
    We've now created a stack of 10 boards that have the same issue, which we suspect to be CPU-related. The issue is very simple--the board will not boot to anything, only showing the exclamatory sign inside a circle. No amount of DFU/restore, wipe/erase, etc, will resolve the issue. No boards have physical damage. We went ahead and replaced the SSD nands on two boards (one 02020, one 02016) and the issue remained exactly the same. We are considering replacing the CPU on one of the boards using a locked CPU, just so we can see if it resolves the issue.

    Has anyone else run into this...

    Best place to source RAM chips? 8GB 820-00850 boards to 16GB or 32GB
    by ugamazing
    I'm looking to upgrade several 8GB 820-00850 boards to 16GB or 32GB for personal use. I am curious what the best practice and process is for sourcing new replacement chips, and what vendor(s) you guys prefer? Another question is, how do I find compatible chips and their corresponding part/model numbers? For example, in the 820-00850 schematic, the DDR chip U2600 model listed (EDFB232A1MA) corresponds to 1x32GB chip. Of course, I would need 4x8GB chips to replace the 4x2GB chips currently on the board. How do I find compatible 8GB chips? Is it as simple as searching "BGA178 8GB 2133"...

    Request for documentation DELL XPS 13 9370
    by ChefDownloads
    Hi all, I am trying to repair a motherboard of a DELL XPS 13 9370 i7 16GB RAM that I bought. The seller misled me with the state of the equipment and it turns out that they have put an ape with a tin soldering iron in his hand doing nothing on this board.... there are several components moved out of place and many others fail. I have many boards of all kinds saved to donate components and this way I will recover it, at least try with everything. In this case I am fortunate to have enough time to try. The information of the board is;
    EDO30
    LA-E672P
