    Gigabyte G5 KE BIOS Password
    by GIGX
    Hello everyone! This is my first post. Hope I dont mess it up I have found this site recently and was hoping if what im about to ask can be done. I have a [U][B]Gigabyte G5 KE[/B][/U] laptop. When I first bought it I did set a Administrator BIOS password but I have forgotten it. It would be very nice if I could gain access to the BIOS again. So is this possible and how should I proceed? The BIOS brand is [B]INSYDE[/B]. Im very new to this so I dont have any experience to be honest. Hope its fine. Thanks a lot in advance.Hello everyone! This is my first post.

    Lenovo ideapad 520, NM-B452 not powering up
    by FrozenHaxor
    Hey, I'm repairing a board from liquid damaged laptop, managed to get 5V and 3.3V rails up, some passives were corroded away. Only problem right now is no reaction to power button, there is no PCH_PWR_EN signal, DPWROK_EC is 2.5V, +1.0VALW is missing. Replaced KBC with brand new one, reprogrammed. No change. Any ideas? Schematic and boardview are available, attached them at the bottom. Boardview file can be opened by "BoardViewer" software.



    Please don't mind the damage near UC4, it was caused by liquid damage and there is battery connector on the other side,...

    optocoupler? B3PBE0000060
    by jm1234
    Hi,
    I'm troubleshooting SN board of Panasonic plasma TV and I'm curious about a component that looks like an optocoupler, it has 5 legs though. I tried to check between legs 1-2, but no diode junction there, it's open. So either that is not a diode there or it's burnt.
    For future searches, the part num is B3PBE0000060, the label on the component says 9157 and N219.
    Any idea?

    Asus X571GT - DA0XKTMB8C0
    by Luís Amaral
    Hello, I have this equipment on bench Asus X571GT and it's driving me crazy, the problem is when it enters the operating system it turns off! I've already reprogrammed the BIOS, tested the software, just connected the motherboard with a USB disk and it does the same, I've already changed the charger IC... with the thermal camera I don't see anything heating up.... I've already disabled the dedicated graphics and it does the same... I don't know what to do anymore!

    Any tips guys ?...

    How to program a specific flash region of a Nations N32G455RE MCU?
    by Nikan.e
    Greetings and salutations!

    I have a device that uses an N32G455RE. Unfortunately, its flash got corrupted. I have a dump of a working chip.
    How can I program a specific region of the flash or the whole flash without touching the RAM, option registers, etc.?
    I do not have a J-Link debugger and won't buy one, as I am not rich.
    I have flashed a Nucleo board with an ST-Link to a J-Link just to find out that the ST-J-Link only supports ST chips.

    What would be the cheapest and easiest option to program the Nations chip's flash without touching registers etc.?...

    Acer Nitro 5 (AN515-54) No charge No power
    by earwig_nick
    Hello all,
    I'm working on an Acer Nitro 5 (AN515-54) with motherboard EH5VF LA-501P with a short on the power rail.
    I'm just learning board level diagnostic, but here is what I've found so far.
    I injected 1.5v to one of the positive leads on the DC jack connector (PJP101) and read about 1.4a to ground.
    I felt around for heat and found the MOSFET at PQB12 is rippin hot!
    when i pulled the MOSFET from the board the short went away. In my mind it was a faulty MOSFET.
    Ordered a replacement and got it installed only to find it gets very hot again and the short returns....

    Old KSC Digmoda DDC552 Bang and Olufson ICE amp My mission to repair.
    by abajor
    I'm about to take a journey into repairing this 3 Channel ICE amp. It's got a bunch of fun components I am not familiar with like Direct Stream Digital chips. It also has some onboard Digital Signal Processor which I haven't identified yet.

    I am not familiar with ICE amp circuits other than they are a type of PWM amplifier so I'm assuming they require a ton of high frequency filtering on the output. I'm also assuming that the output of the DSD chips probably directly feed the ICE amp signal since DSD is also essentially PWM or creating an averaged AC signal using high frequency ~2MHz...
