That's related to your video card. https://forums.geforce.com/default/topic/546712/bsod-nvlddmkm-sys-problem/ might help.
If (1) reinstalling the driver (or installing the latest version), (2) system restore and (3) going back to factory conditions don't help, it's a hardware issue. A work-around might be to only unplug when the machine is turned off or in sleep or hibernate mode.
Hi, I have problem with nvlddmkm.sys. Whenever I unplug my notebook from power and keep it run on battery, I get that blue screen. Please help, thanks
