    lenovo legion 5 15ach6h Power on No Image

    Hi, I have here Lenovo Legion 5 15ACH6H.
    Power on.
    Power Light is on.
    Keyboard Ligth is on.
    CPU Fun is On.
    CPU/GPU will normal hot.
    BIOS already updated.
    I found today that the BIOS battery only has 2.7V, is could that be the reason?

      Check 1.8V ALW to 1.8v VS transfer is correct or not. The most common fault on legion's is 1.8VS drops down to 0.9V-1.2V.

          PR1046 pin 1 and PR1043 pin 1 has 1.8V
          Is that what you meant with 1.8ALW and 1.8VVS?

              You've not even mentioned the mb markings. How do i verify without knowing which board it is? Is it NM-D562?

                              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                              by Tynan Dill
                              I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                              Upon bringing it home and plugging it up, it showed a standby light.

                              I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                              The screen seems to blackout and stay black, but with a flashlight I can see the display.

                              With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                              Assuming...

                              Hi,

                              i've got problem with Lenovo legion 7 16achg6 - no power, laptop on lab PSU does not draw any power/does not power on. While on original charger, laptop does show battery charge(orange led). After power button, top LED's are lighting up - CPU/GPU cold, only heat comes from battery mosfets (up to 45degree, which seems normal on this laptop). Checked First mosfets - correct reading Source and drain 20V - Gate 26.3V. Battery 15.4V, Bios 1.8V, Power button 3.3v. Checked on different BIOS - no change.

                              Board model: NM-D563 Rev 2.0 (AMD Ryzen...

                              Lenovo X240 - motherboard replacement for X250, no image.
                              by andrhouseolly
                              Friends. I beg you to help me in this situation.
                              Lenovo X240 with a video problem. Native Intel drivers are not installed,
                              after installation, a black screen. It works with the standard Microsoft driver.
                              Understanding that there are problems with the video core,
                              I ordered a motherboard from Lenovo X250.
                              The laptop turns on, starts up, there is no image on the internal display.
                              The image is output to the external monitor.
                              I ordered another motherboard from Lenovo X250.
                              The laptop turns on, starts up, there is no image on the internal display.
                              ...
