    lenovo flex 5 14ITL05 bios and motherboard fault

    my laptop is lenovo flex 5 14ITL05

    recently my power supply for this laptop developed a fault.
    which caused a short in my usb c port -- verified with a new charger.

    rant: so, i went to the repair tech in my country, he asked for a huge repair cost when i decided to get it done someplace else this "great person" nicked my bios chip, asked me to be aware for repair scams lol.
    I was stupid and unable to find the flaw at the moment. Another repair tech told me that my bios chip was stolen and an 8mb bios chip is in place of that. he told me that a 32 mb bios chip should be there.

    he got my laptop booting but did not repair the usb c fault, told me to use the dc barrel connector adapter. i thought of using a connector (usb c to barrel type) with my new adapter, he said it was not possible.

    the laptop works, charges, atleast i cannot detect the flaws. but once i shut down it does not powerup like it should . it takes a long time to show lenovo logo. sometimes keyboard flashes several times.

    using lenovo vantage i thought of updating the bios as he (2nd guy) told he had to flash bios he had difficulty finding it.

    the lenovo vantage cannot update the outdated bios. stating that 16 mb space required

    I am sure the bios chip has the right size 256 mb and the same part number W25R256JVEIQ as in the schematic. i have checked personally.
    why does it say 16 mb disk space needed.

          Summary of BIOS Whitelist Removal Problem


          Problem:

          Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
          by Wahaz
          Hello,

          I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
          So I thought it was a Bios problem.
          I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....

          Lenovo Legion T5-26AMR5 Desktop - Corrupt BIOS
          by grimacelord
          Hello there.

          I am working on a Lenovo Legion T5-26AMR5 desktop that currently has a corrupt BIOS and I have been unsuccessful thus far in trying to fix it myself.

          History:

          1. This computer came to me initially with an error message that said "BiInitializeLibrary failed 0xc0000001" or "0135 fan error". It would always be one of the two errors. It should be noted that when it produced the fan error, there was no physical problem with the fans. They were all spinning just fine.

          I searched for this error online and discovered...
