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...

Hello,

I'm hoping someone could help me confirm if I have identified the following parts correctly.

Apparently the DP cable became stuck inside the graphics card and was yanked out. This caused some sort of short which burned the DP contacts and blew some resistors and ferrite beads.

The parts needing replacement are on the back of the board behind the HDMI input.

I have identified the parts as the following:

C6037: MLCC 0.1uf/16v(0402)x7R W05

R6016: RES 499 OHM 1/16W (0402) 1%

LB10911: Ferrite Bead (0402)...

You have a laptop that does not power on, powers on but shows no image, crashes, etc… You want to fix it but you don't know where to start.

There are 2 situations:

1. You just want your laptop fixed
2. You want to learn about fixing laptops

Sorry, but if you're in situation number 1, we recommend you to use the services of a trustworthy professional repair shop.
Unfortunately, if you're not serious about learning, you will waste your time and money, and you will make us waste our time as well.

If you are in situation number 2, then please continue and...

First time dealing with one of these 2023 16" units, and the board model is 820-02917. No schematic available from what I can tell, but a somewhat similar one in 820-02918. I am going to reference certain chips using the 02918 schematic because it will at least let you know what I'm looking at:

Unit had liquid-damage to U5500/UF400/UF500 areas. Had to do a ton of precision cleaning since we don't have any parts for this model yet. Got everything cleaned up but had a few resistors with burned pads that we replaced fine, but without knowing where to check for continuity, hard to...
