    New drivers are installed. What power plans are available to you and what one are you using?

    powercfg /list from a Command Prompt will show you.

    Please fill out your System Specs:

    See here: System Specs - Fill in at Ten Forums

    The more information you can provide the better.

    Also, it looks like there is a BIOS update for your T420s laptop. You have a lot of these Event Viewer entries:
      Log Name: System
      Source: ACPI
      Date: 2018-01-23T19:02:13.092
      Event ID: 15
      Task: N/A
      Level: Warning
      Opcode: N/A
      Keyword: Classic
      User: N/A
      User Name: N/A
      Computer: DESKTOP-062859K
    : The embedded controller (EC) returned data when none was requested. The BIOS might be trying to access the EC without synchronizing with the operating system. This data will be ignored. No further action is necessary; however, you should check with your computer manufacturer for an upgraded BIOS.
    so it would be a good idea to update to the latest available BIOS :

    Thanks for looking at the drivers.

    Here is power scheme info:

    Existing Power Schemes (* Active)-----------------------------------Power Scheme GUID: 1e59434a-f765-42ed-9b18-fceb3998b9ed (Timers off (Presentation))Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e (Balanced)Power Scheme GUID: 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c (High performance) *

    I will start to work on my system specs - that is going to take me a while...

    You are using the High Performance power scheme which means there should be no reduction of power to any of your devices, that's good. I was expecting to see one of the other schemes set active and maybe that being the cause of the problem you are seeing but it doesn't look like that's the case.

    Maybe updating the BIOS will help.

    BSOD is now much worse - happens every time I try to plug power in or out...

    This occurred after recent Centrino 6205 driver update. I tried to go into device manager to roll back the driver for the Centrino 6205, but the device manager says the current driver installed is from 4/30/2015??? I am totally confused...

    There is no Bios update since Lenovo doesn't support windows 10 for my Lenovo T420s...

    Recent dump file is attached

    BIOS has nothing to do with the Operating System, strictly hardware. As I showed, there is a newer BIOS update than the one you currently have installed.

    Not sure whats happening wit the Centrino driver. Dump shows the Tue Jan 6 11:19:19 2015, same as before, unless that file in the new driver did not get updated, which happens some times.

    Thanks for your help - when I went to the link you provided for Bios Update, it only listed older operating systems, so I assumed they didn't want it to be used with Windows 10. So I should just update Bios with the Bios listed for windows 7, 8?

    I am not sure I understand about the wireless driver - should I update again or should I ???

    Thanks for all help!

    if you already updated successfully then updating again will not make any difference. Dumps still show the same driver problems, LAN and WiFi.

    Let's try enabling Driver Verifier, see if that shows us anything different.

    Driver Verifier
    is a diagnostic tool built into Windows 10, it is designed to verify both native Microsoft drivers and third party drivers. Driver Verifier's verification process involves putting heavy stress on drivers with the intention of making bad, outdated, incompatible or misbehaving drivers fail. The required result is a BSOD (Blue Screen of Death) which will generate a crash dump for debugging purposes.
    Machines exposed to Driver Verifier will run very sluggishly due to the stress being applied to the drivers.

    Driver Verifier - Enable and Disable in Windows 10

    Pay close attention to PART TWO and make sure the correct boxes are checked.

    It is not advised to run Driver Verifier for more than 48 hours at a time. Disable Driver Verifier after 48 hours or after receiving a BSOD, whichever happens soonest.

    Always create a Restore Point prior to enabling Driver Verifier.

    What we're looking for is a verifier generated BSOD with a mini dump that will tell us what driver caused it. If you get a BSOD, run the new log collector and upload the resulting zip file. It collects similar data.

    Make sure you understand how to disable Driver Verifier.
