    Fixed: Lenovo P14s Gen 1 (type 20Y1, 20Y2) Laptop (ThinkPad) bricked by a withdrawn BIOS update (r1buj82w)
    by akwky
    Hi!
    Went dumpster-diving and found a bricked Lenovo P14S in trash, few weeks earlier. Symptoms - no screen, no POST, no beep, just keyboard LEDs flashing on powerup. Mute button+LED was responding though, and the display self-test was still working (via the key combo Ctrl+Fn+Power held for some seconds, see the Service manual).

    Incidentally, Windows 11 have recently started auto-flashing computer BIOS in our region. Even more suspiciously, Lenovo has released a BIOS update just few days before the PC was trashed. About a week later, the BIOS update image has been oficially marked...

    A1706 2017 critical update
    by iMuhtaseb
    this board suffered from a bad trackpad and bad keyboard after liquid damage; board was turning on no issues..
    we've replaced the bad trackpad and bad keyboard no issues whatsoever.. during 2nd final checkup we booted to an external macOS and there started the critical update issue; it boots externally but to the internal SSD it shows critical update; tried Wi-Fi tried Ethernet tried Hotspot same thing..
    One weird symptom is it takes too long to power on and show the Apple logo for some reason..

    Update bios EFCN58WW to EFCN59WW for solving The Connected AC adapter has a lower wattage than the recommended AC adapter




    I have a Lenovo Legion 5 15imh05a device that I bought used online. It came with a 20V 8.5A 170W charger.

    The BIOS version is EFCN58WW.

    When I turn on the device, it displays the message:
    "The Connected AC adapter has a lower wattage than the recommended AC adapter..."

    The device rarely charges the battery, and even when it does, it doesn't show that it's charging.

    I've tried
