    Re: very challenging issue! lenovo G50-80?

    To give a little more insight:
    This is my board type aclu3/aclu4 uma nm-a362 rev1

    when you plug in charger the led lights up. you hold the power button led goes off. Press power button turns on again. If you connect the batter the battery led lights up and chargers.. It just does not post no fan, keyboard light. I checked and cleaned ram swapped it around used external display. still black screen. The only strange thing is 7volts on pin5 Pu904

        Lenovo legion 5 pro startup issue
        by shahnld
        Good day Experts
        I have a lenovo Legion pro 5 16ACH6H with AMD RYZEN 7 5800H and RTX3070,.

        A weird issue has troubled me. If i power on off the laptop 20 times then only power LED will lit but no fan spin no display. At this stage gpu, vram. DDR voltage. 5v 3.3v 1.8v and the rest are present and cpu core is stuck at 0.84v.

        And sometimes lets say the 21st time it will boot perfectly and there is image and everything is working perfectly and at this stage i see cpu core...

        Lenovo Ideapad 5 15ARE05 startup issue
        by db80
        Hello friends,

        I've been racking my brain over the past few months on the following issue:
        I have a Lenovo Ideapad 5 15ARE05 laptop that basically works fine as long it starts up at all.

        If you shut it down, often you hear the HDD still spinning and the Power LED remains on, it only shuts down if you force it (pressing the power button for like 15 seconds).
        Then, if you want to Switch it on, nothing happens, only the Power LED lights on, nothing else. If you leave it, then after like 30-60mins it turns on itself.
        I tried all the common alleged „fixes“...

        For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification.

        Lenovo Ideapad 3 15ALC6 motherboard issue
        by totof
        Hello,
        I have a Lenovo Ideapad 3-15ALC6 computer that I'm trying to repair.
        Initially, the computer wouldn't start, and there was no power consumption from the charger. The board itself is reference HS261&HS561&HS761 NM-D521 rev 3.0, where you can find the schematic and board view here: https://www.badcaps.net/forum/troubl...-hs761-nm-d521

        When I opened it, I noticed three burnt components near...

        Lenovo P43s won't boot with internal battery connected – looking for help diagnosing battery issue
        by code share
        Hi everyone,

        I'm having an issue with my Lenovo ThinkPad P43s. The laptop does not power on when the internal battery is connected, but it works fine on AC power alone (battery disconnected). Once the battery is reconnected, the system becomes completely unresponsive — no lights, no fan spin, nothing.

        Here's what I've tried so far:
        • Power/EC reset (held power button for 60 seconds with battery and AC disconnected)
        • Booted successfully on AC power only with the battery disconnected
        • Visual inspection of the battery — no swelling, burn marks, or connector damage
        • Battery
        ...
