    Search BIOS thinkpad e14/e15

    Hello,
    I have 2 laptops E14 and one E15 with the same problem: don't turn on (no led) I suspect the bios and I have buy an CH341A.
    But now I need a new bios...
    I give below the older bios, can you check it please, or give a valid version of BIOS?

    I will be very grateful to you

    At first, this is the numbs of a e14: 20TA-00EWFR
    with a bios chip: Gigadevice GD25Q80
    Motherboard: GE4B0/GE5B0 NM-D011

    thanks

              What is the point in giving you a bios,what are you going to flash it to.A bios can only be flashed to the correct chip. You must make a backup before erasing or flashing any other bios. Find all SPI chips using the schematic/boardview https://www.badcaps.net/forum/troubl...-1-0-schematic

                          If you have a WSON adapter board yes.Its essential that you make a good backup before erasing the chip or trying to flash any other bios.Post your backups here and we can check if they`re any good or not.If you don`t make backups you will make more problems for yourself.
