      Texas Instruments bq24745 bq24745RHDR bq24745RHDT Battery Charger IC for Laptop Computers Datasheet
      by Document Archive
      The bq24745 bq24745RHDR bq24745RHDT is a high-efficiency, synchronous battery charger with an integrated input-current comparator, offering low component count for space-constrained, multi-chemistry battery-charging applications. The input-current, charge-current, and charge-voltage DACs allow very high regulation accuracies that can be easily programmed by the system power-management microcontroller using the SMBus interface. The bq24745 charges two, three, or four series Li+ cells, and is available in a 28-pin, 5-mm x 5 mm QFN package.

      The bq24745 features dynamic power management...

      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.

      ⚠️ New Problem: One USB-C Port Only Works in One Orientation...

      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...
