    Need a HP 255 G8 (HPL51 LA-L021P) BIOS
    by mitchw
    Looking for a BIOS for HP 255 G8 (HPL51 LA-L021P).

    The main problem is that the laptop will crash while booting to OS. Will crash even on booting from USB, like a Ubuntu or to a Windows 11 installer.
    Before junking the board I would try the new BIOS if it does anything.

    Thank you!...

    Asus X705UV bios
    by MDSI
    Hello.

    I have an Asus X705UV which no longer starts since the last Windows update. I suspect Windows Update of having tried to update the bios and having corrupted it, because currently, I have the charging indicator when I plug in the charger and I have the power indicator when I press the on/off button but nothing more, not even a fan running.
    Could someone check this bios and if it is broken, repair it?

    Sorry in advance, google translate is useful but not perfect. 😂

    Thank you in advance !​ 🙏...

    Sony LED 65X9005A shuts down after few seconds - looking for help
    by tec3000
    Hi community! Germany calling I am wondering if you guys can help me out. I have an issue with my Sony LED TV. I've been told this is a good place to ask. Thanks for anyone who will reply and offer advice. Appreciated!

    I have a KD-65X9005A Sony 4k LED TV. For a few weeks I've got this problem where I turn on the TV and within a few seconds the TV starts getting darker until it shuts itself off and I get the 4 blinking error code. HOWEVER there is one exception: Whenever I switch to the i-Manual, a full screen on-screen instruction manual, the TV never turns off. I tested for hours!...

    Hello guys,

    Got my hands on this laptop and started troubleshooting. The only thing I know is it turned off and never came on. No lights and not coming on.

    Started doing some checks and found the main rail present everywhere. Something weird though as the gate of the first input mosfet is 3.7V and the output is 20.3V.
    Tried to trace the gate and it looks like it's connected to pin 61 on the io. Is the IO supposed to monitor the gate voltage?

    5V and 3.3V are missing from the coils. Found by lifting PL6202(on the 5V rail) the clicking fet sound goes...
