    by smic717394
    Hi,

    I need a bit of help. I have a Macbook pro end 2011 8.2. I bought it of a customer cheap because it has a bulged battery. I replaced the battery and upgraded the ram 2x8GB total 16GB, and replaced the HDD with a SSD. What happens with this laptop is very strange and I don't know where to begin. The laptop doesn't panic, tha fans run normal even when the kernel is 100%. If I reset the SMS, will run normal for about 30 to 1 hour then the kernel_task goes to 95% and the laptop become unusable. If I reset the sms agail will run again normally for some time. I thought is the battery,...

    need help to modify a bios dumped from set-top box
    by jason0503
    The set-top box has a TV silicon tuner IC MXL608, which has a programmable channel selection filter (6MHz/7MHz/8MHz), and the default value is 8MHZ, but the manufacturer sets the set-top box to 6MHZ. How can I change this value by modifying the dumped bios? I tried using UEFITool.exe, but it doesn't work. The BIOS of the TV box is different from that of the computer. I don't know how to modify it or what tool to use. I downloaded the data sheet of MXL608, which mentioned that when the value of SYMBOL is set to 2.85, BW=6MHZ. When the value of SYMBOL is 3.75, BW=8MHZ, but I can't find the corresponding...

    ASUS M5A78L-M LX - PWR button works sometimes, CPU stuck in reset
    by kotel studios
    Hi,
    Firstly I'd like to apologize if this was posted in the wrong forum (I'm new here )
    Recently I got an ASUS M5A78L-M LX board in a scrap lot. Saw one broken cap which I've replaced. No broken traces and missing components. While soldering a new cap a bit of solder got onto components bellow SB (opposite of the two lythic caps). Didn't see it and powered the board on.
    I was greeted with it not starting. Came back to it a day later and shorted the PS_ON with GND to force it on. It sprung to life but with CPU stuck in reset (it was an FX 4600 I believe). Thats when I saw the...

    This BIOS dump came from a Samsung Galaxy Pro NP950XDB-KC3US that will NOT POST. It powers on, has keyboard backlight, fan spin, and a flashing blue LED near the USB-C port.
    I don't know if anyone here can clean this BIOS dump for me. I have purchased an identical used motherboard, which will arrive next week. I should be able to get a good BIOS dump from that working board.

    by sauce
    Hi,

    I would like some help on my wife's laptop Dell XPS 9343 with LA-B441P motherboard.

    AC adapter is not recognized so I bought another used one and still the same !

    It was of course working with the old one the bios was saying 45W adapter but now it says adapter unknown.

    I don't know if the used one is also defective or it's a motherboard issue.

    I have already repaired this laptop to give it to my wife (the PD102 TVS was bad).

    For now what I checked :
    - If i measure old adapter the center pin measure nothing...
