    Hello, my name is Collins Lawrence frm Uganda.
    I bought Lenovo laptop mode G50-30. it’s one month out of warranty hut all ports are non functional.
    The technician frm the shop where I bought it is telling me that it’s the problem with the motherboard. he has installed Windows 10 but I bought with Windows 8.1.

    Am confused because the computer can be powered on, en it opens. I had thought its the problem with drivers but the technician says It’s motherboard problem.

    that I need to buy a motherboard. May I be helped without buying the motherboard?

    replace the motherboard is the last choice, first install drivers, if doesn’t help check bios setting.

    Boot into the BIOS via the UEFI Firmware Settings or by pressing the OneKey Recovery button (while the computer is turned off).

    Wait for the BIOS screen to appear. Find the factory reset option.
    Select the option or press the button to load your factory defaults.
    Save your changes and confirm your selection if necessary.

    Hi Friends,
    many times when you solder a new ITe ec and try to program it with svod(with correct pinout downloaded), we get a message “ITE series not detected”. This is very common issue while replacing Lenovo G50 series with NM-A311/271/282 etc motherboards.


    You just need to trigger the motherboard once(means press power switch once) after connecting with svod and after doing setup,connecting adaper and gnd. In otherwords you need to press power switch once after doing all whatever is required to program ec.

    Learnt it the hard way after replacing 3 IT8586E ec on Lenovo NM-A311 mb and getting same error on svod-ITE series not detected.

    Hope it helps someone
