    ASUS X512DA BIOS MOD
    by Oficinadopc
    I'm trying to enable this Asus X512DA. This model came without backlit and I ordered a keyboard with backlit. As I've been searching on the internet, It seems that the bios as to be modified at the offset DD to 7E. Since I don't have enough knowledge to the task, is there anyone who can make it for me? I attach the original bios file.

    Really appreciate the help...

    Quecoo T12-958 soldering station - INVER error?
    by spleenharvester
    I bought a T12-958 recently with an M8 handle and until now it has worked very well. The tip wasn't earthed but that was easily resolved.

    Now, whenever it is switched on, it heats up to about 70*C then shows an [INVER] error on the screen and stops. In order to fix it I have to either unplug and re-plug the handle, or unplug and re-insert the tip from the handle. While doing that it changes to [ERROR], then it finishes heating up and works perfectly. Until it's turned off, after which it will show [INVER] again next time it is turned on.

    Any idea what the problem is?

    A1706 short PP3V3_S5
    by madjid911
    Hi friends,

    I have a macbook pro A1706 820-00923-A that won't start no signs of life, no liquid, checking the voltages I found PP3V3_S5 was shorted, I removed all the processor coils, but when I 'injects a voltage it is the processor which reacts, can you confirm to me that this is definitely coming from there please?

    I have 20V on the usb-c connector, and 13v stable on​ ppbus_g3h.
    I saw that a track had burned out on PPVIN_2V7NAND_LB after resistor R9350
    I injected voltage on L7660 pin 1 in short but only the processor reacts

    Thanks for your...

    Working on this macbook, showing 5v 0A from charger - dead. Board is clean - no liquid, owner said he left it charging and died. Some voltages:

    After looking at board closely found L8430 damaged/blown open circuit so replaced it. No change, still 5v 0A - I'm thinking over current on L8430 (PP3V8_AON_MPMU_ISNS_VIN) killed U8100?

    A1708 820-00840 20v 0a
    by sewsulle
    Good Afternoon,
    This is my first post here so I apologize if I miss something.

    I'm working on an A1708 that draws 20v and 0a with the board removed.
    When installed in the machine, it takes 20v and 0.1a. The fan spins up and the trackpad clicks.

    Some measurements:
    PPBUS_G3H: 13.13v
    PP3V3_S5: 3.3v
    PP5V_S4: 5.1v
    PP3V3_S0: 0.6v

    Any help would be appreciated. Let me know if more measurements would help.
    Thanks in advance

    by chickenhawk88
    I was wondering if you guys know anyone that sells Super IO chip ITE IT8390-256 flashed with your specific laptop. Im debating to see if this available out there vs buying chip and programmer myself. Right now the chip plus programmer is about $60. But i still need the file that goes on chip. The laptop is RAZER BLADE 15 RZ09-0369.

    Looking for help with a Viewsonic VP230mb where the backlight comes on only momentarily
    by lostone
    Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.

    First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
    When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...

    by Ariel Ruiz
    Hi, I will appreciate if I can get some advice on my problem.

    - I have an Acer Aspire A315-41-R8J9, with Ryzen 5 APU (no GPU).
    - The laptop can be started (blue led on) but it shows no picture (blank screen), and it looks to be somewhat active, as the fan spins, and processor gets hot.
    - I visually inspected and tested some components, with no obvious issues.
    - I disconnected not-essential peripherals.
    - When testing PL401, I got sparks, smoke smell, and the Acer logo briefly showed in screen but then shut down.
    - I tried to re-flash BIOS from USB (Fn+Esc),...
