Windows 10: Frequent BSOD on Thinkpad X200 tablet with two screens Solved

    Frequent BSOD on Thinkpad X200 tablet with two screens


    I upgraded to Windows 10 a few days ago, and have been experiencing frequent BSOD over time for different reasons. Attached is the log of the last one I just encountered today (there are also dumps from some of the earlier BSODs). It occurs when I am not by the computer as usual again. This time, my external monitor was plugged in but not switched on as an extended monitor. Before this one, the BSOD were usually coded as CRITICAL PROCESS DIED or SERVICE error or similar for different reasons. But most of them occur when there is no activity on the computer for a while. My external Dell monitor was usually plugged in as the extended monitor. Those BSOD also caused some hard driver errors which I have fixed yesterday. It also cannot automatically login despite I have set it up.

    Basic info on my computer: Lenovo Thinkpad X200 tablet, with Mobile Intel 4 Series chipset of graphics card. From my device manager, I didn't see any obvious problem with drivers so far. Intel does not provide a proper graphics driver for WIndows 10, but I want to use OpenGL.

    Hopefully you can help me figure out what's the problem and how to fix it. Thanks.

    Just got another BSOD while I left my office for a while. Attached is the dump file.

    PS: I tried to read the dump file by installing windows debugging tools, but I got the "win32 error 0n193" error. I tried to use the x86 windbg.exe, no success. If anyone can point out how to read the dump file by myself if analyzing the dump file will take a while, I would appreciate it!

    I saw your post on SF about the Windbg, maybe trying the W10 version and following this tutorial will help,

    WinDBG - Install Configure - Windows 10 Forums

    You shouldn't need to download symbols if you have the path set correctly.

    On to your dumps, your second upload is corrupted but there's a clear culprit in all your dumps,

    BugCheck 3B, {c0000096, fffff8012654223e, ffffd00023e0ae30, 0}

    Which is the power management port driver.

    You can see if this fixes it,

    Lenovo Power Management Driver for Windows 10 (32-bit, 64-bit), 8.1 (32-bit, 64-bit) - Laptop - Lenovo Support (US)

    Your specific model (X200) isn't listed but is listed in the readme.

    @derekimo, I just followed the Windows 10 instruction on installing WinDBG, and not I can read the .dmp files :) Thanks!

    On the BSOD, my model x200 only occurs in the Windows 7 system list of the README file. Anyway, I have installed the new driver, and will report back when the screen turned off in a few minutes under current setting.

    Glad you got the WinDbg working, You're welcome. :)

    Yeah, I saw that it was listed under win 7, but it's that driver in every dump so it's worth giving a try.

    Turns out, that driver does not solve the problem. It just crashed again while the screen saver was starting. Seems the same problem happened (see dump).

    Can I do anything for further tests? Or, is there any way to modify the current driver to make it work for Windows 10? I guess the Power Management driver provided by Lenovo may only work for Windows 7 on my machine...

    It doesn't look like it actually updates the driver,

    Is there a program installed for power management? You may want to uninstall that to test if helps.

    Seems there is a Power Manager software from Lenovo to serve as a UI. Now I am uninstalling it...

    So far, no BSODs show up! Several rounds of screen saving sessions have passed. I guess it works for me. I just found a few small issues, like the short key (Fn+F7) to switch the dual monitor modes stop working; I cannot set the starting & ending points to charge the battery. But I think those are fine for me.
    @derekimo, thanks for your careful analysis! I will tell the solution to other Thinkpad X200 users who have similar problems.

    You're welcome. Hopefully they get that sorted out so you can use it again if you want.
