BSOD during Sleep and power off on Ideapad U330 Touch

I have an Ideapad U330Touch with Windows 8.1 since one year without any problems. Since about a month ago the system does not power down or does not properly go into sleep mode. In all situations there is finally a time out and the system generates a minidump Driver Power State Failure with bug check code x9F and parameter 1 = 3, a device object has been blocking an IRP for too long a time.

 

By using the windows debugger I came to the conclusion that the Intel Wireless-N 7260 driver netwbw02.sys causes these problems.

 

I updated every driver from lenovo and other vendors I could find and I also used the latest BIOS version. I removed also programs which I installed at the time when I got the first BSOD problems. Finally nothing solved the BSOD problem. 

 

The only thing that solved the problem is when I remove the Wireless Lan device from the configuration. When I do that everything works fine no matter which drivers I use.  I have used about 4 different Intel Wireless-N 7260 drivers but non of them solved this problem.

 

When the system shuts down without a BSOD it starts very fast but when it had a BSOD during a shutdown starting the system takes quite a long time. ALso windows does not save certain changed settings becasuse of these BSODs.

 

To me it is obvious that the Intel Wireless-N 7260 LAN  card causes this problem. I want to hear from other forum mebers what they think about my problem before I go to the repair shop for replacing this LAN card.

 

I also saw from other entries in this forum that there are many problems/failures with these Intel LAN cards. Are there any other options for the Ideapad U330 Touch?

 

I hope to hear soon from the forum members and Lenovo support engineers.

 

Thank you so far for showing your interest and support.
