    Guys I have set top box which has no power on in specific case. When I insert antenna plug which has 12V on it because of dB gain device on top of antenna, device if its turned off, it will not turn on.
    After I need to open the case and short + and - on ABS10 chip and after that device will turn on, without antenna plugged in, after its turned on I can plug in antenna and it will work fine, but I notice there is some extra heat inside the unit.

    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 ...

    T430 laptop doesn't power on- please help me troubleshoot w/multimeter (fixing for fun)
    by max_smart
    Hi all,

    First off, this forum really helped me out by advising me to cut some ribbon connectors to the LCD panel in order to fix a 70" TV (lots of threads on Sharp TVs with this issue). I didn't believe that it could work, but it did.

    Now I've been encouraged to try to diagnose something quite a bit more complicated. That is an old T430 motherboard. I work on a college campus so I have access to pretty decent tools. I found the schematic for the motherboard on the site, and have been following traces and taking DC measurements from things. I also don't mind...
