I lost the screws that came with the kit. Does it matter what screw is used, as long as there are washers.

Re: TNPA5623 Screws Arcing Issue
I would use some good quality screws that are stainless and have lock washers but not the kind that will mar the board, the lock washers have to be underneath the standard washer and the screws that go to the SC board to the buffers cannot be longer than the end of the board if they go too far they arc against the back side of the panelDid I leave the soldering iron on? -

Re: TNPA5623 Screws Arcing Issue

Hi everyone,
I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.
🛠 Original Issue
The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.
I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

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 guys!
I have a strange issue with my laptop keyboard and I'm lost trying to detect what's wrong - the KB9028Q-C or the keyboard itself.
It powers on OK and has no other issues except the following:- CAPS LOCK does not work at all
- Fn button toggles Flight Mode
- When I press 't' or '5', it produces 't5', and when I press 'y' or '6', it produces 'y6'
- (with SHIFT pressed: 't%' and 'y^' respectively)
but when I press and hold...06-27-2025, 01:10 AM -
Hello everyone,
I'm experiencing an issue with my Alienware 15 R2 (Service Tag: DL7NN32). The laptop works perfectly when connected to the AC adapter — it powers on and functions normally. However, the battery does not charge. If I disconnect the DC adapter, the laptop shuts down immediately, as the battery is at 0%. I have replaced the battery with a new compatible one, but the issue persists. I also replaced the AC adapter with a compatible one, but the battery still doesn't charge.
To assist with troubleshooting, I'm attaching two power circuit schematics:- Power
