    Macbook Pro A1707 820-00281 Stuck @5V
    by JasonC89
    So I have an Macbook Pro that came in for no power (I dont do a lot og Macbook repairs). After some testing I found it was only getting 5V with very little current draw, if any.
    I searched around for shorts, and didnt find any. No real signs of liquid damage etc.

    Following a couple of questions from other members here I was able to further test voltages etc. Im now at a point where PP3V3_G3H is showing, but only at 2.23V.
    I have 5v on the Enable pin.
    Also the dual diode D6902 is showing :
    5.19V @ Pin 1
    0v @ Pin 2
    4.15V @ Pin 3

    I have a lenovo ideapad 5 14itl05, board LA-K321P, That will only power up on Battery only, or with battery disconnected and power adapter only. If battery is connected and usb-c power plug connected. It only works on battery and will not charge. I can however force it to charge by connecting the battery from a disconnected state while the power USB c plug is powering the laptop.

    Additionally....to add to this strange situation. The usb-c power plug ONLY works to power the laptop on one side when inserted into the boards power usb c plug. If you rotate it 180 degrees, the board gets...

    Dell LED Monitor Model SE2717H
    by angelos
    Hi Guys, i just have a question that is probably easy to answer if you have experience on such matters.
    My Dell Monitors screen was damaged by lightning via the HDMI port. The monitor does come on but cannot display HDMI or VGA image. it says no signal.
    I have ordered the board on Aliexpress. They say 100% working. Don't trust. it.
    My question is, after installing the new board, is there anything else I need to do in order to make this board work. I know on some TV's you need to load software on the board to make it work but this is a monitor or even having to go into service...

    Hisense 55E76GQTUK screen removal?
    by Runlinc
    Hi all, I need to change the backlights in a Hisense 55E76GQTUK. The screen is glued to the chassis, what is the easiest way of delaminating the screen from the chassis please?
    also what double sided tape would you recommend to glue it back in? ….. or is that a question to ask once the screen is out in one piece?
    Many thanks for any ideas you have.

    Asus M7600R BIOS Password request/removal
    by Johnny h
    Hello,

    I'm hoping someone can assist me.
    I have an Asus Vivobook 16x Pro OLED laptop which has a BIOS password, and I can't seem to find it.
    It still boots into Windows (boots from whatever SSD is installed but not from USB).

    The model number is M7600R and serial number is N8N0CX03H71131C.

    I tried AMITSESetup Decryptor but the password I got doesn't make sense (it's got a line break and special characters).
    I also tried to use *************** MOD EDIT ,redacted************** and it also gave me the funny password of

    by EazyBone
    Another eazybone post took on this OLED now.

    Symptoms. Hit power, white light shows briefly and then 5 blink red code. TCON issue per chart on first picture.

    I'm thinking I have a power board issue though, which is one of the options

    Now to check pin voltages from PSU to main and PSU to tcon

    Pic 2

    1 tcon on 12 -- 0v (when I hit power this goes to 3.1 stays for short time and back to zero)
    2 bl err -- 0.16
    3 evdd on --0
    4. Ac off det 3.187
    5 power on -- 3.362 BUT fluctuating randomly to 3.352
