    Lenovo T470 Turn on and off in seconds while charge

    Lenovo T470 turns on and off in seconds while charging. But it won't turn on without charging.
    The power supply generates 0.1A, turns on with the orange LED, the fan spins for 1 second, and off.

    It looks like the motherboard has some work previously on the CPU and another component. came to me also without cmos battery.

    I don't have boardview for further examination.
    Please kindly assist me to solve this problems..

      What are the silk screen markings on the board? Should be 'NM-A931' or similar.

          Lenovo Legion 5 high fan spin turns off after 34 seconds
          by twonk9098
          Hi all,

          I have a Lenovo Legion 5 with a Ryzen 7 series CPU and RTX 3070 GPU. My issue is that it turns on and all seems fine except after a few seconds the fans spin up high and the laptop turns off after 34 seconds.
          I can get into bios and can even boot and login to Windows however after 34 seconds no matter if Im at the bios screen or booted into Windows it will just turn off.

          I have managed to run HWmonitor and the temperatures of the CPU and GPU are fine, I can also touch the heatsync which is warm but not hot.

          I have tried a few new bios but exactly...

          Lenovo 15iml05 Power led lights for 12 seconds then off 12 seconds

          Hello. I bought a faulty Lenovo ideapad 3, but it turns out the 3Valw buck converter burnt a hole through the board. I was able to clean it up, and remove all the shorts. I now can power the 3.3v rails from a bench power suppy while connecting the laptop to its psu, and I get the additional 5valw, 1.8v, and 1.05v, form what I can tell in the schematics, those are the only 4 voltages I should see before turning on, and they are present. When I hit the power button, the power indicator on the left side turns on (not the one on the power button), stays on for about 12 seconds, then turns off for...

          Lenovo S145-15IL won,t charge
          by Zippo978
          Hi everyone,
          I have a Lenovo motherboard Lenovo S145-15IL, NM-C711.
          Initially it wouldn't turn on, I replaced the PQ100 and PQ101 mosfets and the BIOS chip and it works perfectly except charging the battery which says it's connected and charging but the percentage doesn't go up. In pins 1 and 2 of the JBATT5201 I find 7.8V, and at the input of the PQ102 and 103 mosfets I have 19V.

          I don't understand why the battery doesn't charge, thanks in advance for your help.

          P:S: Thinking it was the battery I replaced it with a new one and updated the BIOS and Firmware....
