    Prevent tab bonding issue?

    Hello!

    Thank you for a great forum. I'm no expert by no means, just trying to learn.

    I've read some about the tab bonding issue that affect almost all manufacturers(?), maybe Samsung is over-represented?

    From what I can understand, it looses connectivity when overheated. Would added cooling prevent the issue?

    I use a small dab of thermal paste on the Ic on the driver help it transfer heat to the chassis better.

      MacBook Air A2337 (820-02016) USB-C Port Issue – Only Works in One Orientation (CC Line Problem?)
      by rounin
      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.

      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...

      HP 15-cw1002ua strange keyboard issue

      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)
      I initially thought it was a keyboard malfunction (internal short, etc.),
      but when I press and hold...

      Alienware 15 R2 Service Tag: DL7NN32 ISSUE (Battery is not charging)
      by Simone Vergani
      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:

      Dynabook Satellite Pro C50D-B-100 - BIOS Issue, Black Screen
      by wizard13
      Hello everyone,

      I am experiencing a BIOS-related issue with my Dynabook Satellite Pro C50D-B-100. When I power on the laptop, the screen stays black, and there is no response from the system. I suspect a corrupted BIOS.

      I have checked the forum and the available documentation but could not find a solution specific to my issue.
