Thinkpad Edge E420 Blue Screen/Black Screen Closing Laptop

Hey all,

 

My wife's laptop, e420, has been having issues for the last 3-4 months. It started where she would shut the laptop and it would not go to sleep, the screen would just be black. You would have to hit the power button to wake up. A new issue is that we get the dreaded blue screen. The error shows that there is a problem power management when shutting the laptop.

 

I have tried to debug the dump file with little help and I have updated all the drivers. I have a feeling the power management drivers became corrupt on an update but not sure. Any thoughts? I have updated the bios as well.

 

Thanks!

I'd start by repairing or reinstalling the OS and go from there. Then you'll know wether is hardware or software related.
