    Power Issues with Lenovo IdeaPad S540-15iwl

    Noob here trying to troubleshoot a
    Lenovo
    IdeaPad S540-15iwl
    Model: 81NE
    CPU: Intel i5-8265U
    GPU: UMA
    RAM: 8GB removable 4GB Soldered on (12GB total)
    Storage NVME
    Bios Version APCN38WW

    Sticker on Motherboard:
    FRU5B20S42213
    911
    8S5B2042213HBDG9AY118P
    ---
    The system cannot boot with Battery connected new & old battery
    The system cannot restart, CTRL+ALT+DELETE does not work in bios either however saving a setting in the bios and exiting will reboot the laptop.

    What I've done so far:

    Bios update (from Lenovo's support page) [No Change]
    Replaced battery [No Change]
    Disconnected Primary & CMOS Battery, left unplugged for a week. [No Change]
    Removed Wifi card [No Change]
    Disconnected Fingerprint module [No Change]
    Removed SSD/NVME [No Change]
    Removed Ram that can be removed [No Change]
    I also tried to connect the battery after it has booted up. This causes the system to, hard freeze, sometimes immediately sometimes up to 5 minutes.
    Powering on, connecting battery, then disconnecting PSU- Still freezes.
    The system will still shut down by holding the power button for 6 seconds.

    Does anyone have a solution?

      Lenovo IdeaPad Gaming 3 15ACH - Ideapad 3 well known solder joint issues
      by Nagyesz
      I have a Lenovo IdeaPad Gaming 3 15ACH, which has started exhibiting the well-known issues of the Lenovo IdeaPad 3.

      All stress tests run perfectly, and there are no performance issues. However, the solder joints are almost certainly starting to fail. If the top two screws on the back are not screwed in, moving the screen results in a BSOD or, in some cases, a slight artifact and freeze. This is a 2023 notebook..

      How can I extend its lifespan? Could reflow help?

      It has ryzen 5 5500h, rtx 2050, no soldered ram.

      Example of the artifacts:

      Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
      by Bowline
      My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

      Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

      My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
      The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
      I have tried multiple different Dell power adapters. My Dell...

      NM-B452

      Hi guys. I've used the forum a lot but never asked questions before. I had a Lenovo come in that was shorted on the 20V rail. I fixed that and thought my job was done until I realized it wasn't charging the battery. Here is what I've checked so far

      On the BQ24780SRUYR charging ic
      VCC 20V
      SMBUS lines
      SDA 3.3V
      SCL 3.3V
      Current Sensing lines
      ACP/ACN 2.3 ohms
      SRP/SRN 21.2 ohms
      REGEN line 6V
      PHASE .84V with no battery installed(this may be normal)

      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
