    HP ENVY Laptop 17-cg1008ca Motherboard GPT70 LA-J504P
    by eagleeyez
    Hi,

    I am looking for the schematic of this motherboard or this component, PQB4 reference (Unable to read the text beyond P5)

    Also, if someone with experience could tell me, why would this component burn in order to avoid this happening again?

    Thank you.​

    Asus Vivobook S14 Flip OLED TP3402 AFUWINGUI memory dump error for decoding lost BIOS password
    by Przmx
    Hello everyone,

    I'm an owner of an Asus Vivobook S 14 Flip OLED TP3402 laptop (TP3402ZA-KN063WA)
    with serial number: NBN0LP019584459
    and I lost the BIOS password that I set in this laptop one year ago.

    I tried to recover the password using the AMITSESetup method described on the forum. I found that it is possible by software to obtain the BIOS file from my computer (afuwin.rom), but when trying to do so in AFUWINGUIx64 I received the error number 31 "Unable to read contents from specified file" shown in the attachment. I don't have a programmer,...

    How do I flash bios to an Alienware M16 R1 AMD edition?
    by Arc717
    I am trying to downgrade my bios on my Alienware so I can undervolt & overclock my CPU, and overclock my ram. I need to get to bios 1.2.2 for this. Dell doesn't allow downgrades, and their bios file is an exe compiled in c++, so I can't decompile it easily. I am wondering if I can flash the bios manually using a usb flasher. I would like to know if this is possible, and if so, where the bios chip would be. I know flashers are pretty cheap and the bios chip is 8-pin. There are two of these chips only when I open the back panel of the laptop. I'm not sure if there are any on the other side of...

    ATX brown wire sense range
    by harp
    I thinking to modify some ATX ver 1 supply, and wonder what if I connect 10k pot on 12v and center tap on brown wire? What range of 3.3v correction can to expect, or something will blow up if I close to rails, leave narrow 3.3v range?

    It is KA7500B ic, but 3v3 sense is connected to TL431, I am not sure there is any connection between.

    Hp pavilion 14 - No display
    by Nagyesz
    Hi all,
    Model: HP Pavilion 14-ce3010nh 8BV97EA
    Board number: DAG7ALMB8C0 - G7AL REV C
    Issue: I have an HP Pavilion 14-ce3010nh 8BV97EA laptop. When plugged into the charger, it turns on, but there is no display, the fans do not run, and the processor gets slightly warm. Unfortunately, I haven't been able to figure out what the problem is. I've reflashed the BIOS twice without any success. No post. Already tried out with another ram stick with no luck

    I measured the voltage with the HP turned on in red, and I measured their resistance with the HP turned off in green....

    Huawai Matebook X Pro Mach-W29 - No display
    by Sofian75
    The laptop is working fine except that there is nothing on the screen.
    I can use it with a HDMI cable on my monitor, the laptop display is not detected in the windows device manager.
    I ve already ordered a new LCD assembly but I am worried that it could be a waste of money if the problem is somewhere else.

    I took of the screen and can't find anything wrong with the cables, except I have 3v instead of 19v on what I assume to be the power pin (?)
    What should I check?
    Could it be a corrupted bios issue?

    I can't find a detailed bordview so really don't...

    Lenovo Legion 5 15IAH7 - NM-E241 Rev 1.0 - BIOS fix needed
    by Mirenia
    Hello everyone,

    My Legion 5 15IAH7 won't post. won't boot. No fans, no keyboard backlight.
    Online power led and charging led lights up.

    My guess is that there is some issue with the BIOS.

    It's the NM-E241 Rev 1.0 motherboard.

    As I found out there are two BIOS dumps needed for this board.
    One 16MB and one 8MB.

    I've got both uploaded. Can you maybe check and fix this BIOS files?

    Thanks a lot in advantage ...
