Solved Driver Power State Failure after enter sleep mode

I am using lenovo G580-20150.
I know this problem have been opened a tread but the problem i dont' think it's same so i woud like to ask for some solution after listening to my problem.
I have been user of windows 8 and 8.1 for quite some time.
everything works fine for me for the windows that i currently using , windows 8.1.
including i can put in sleep and wake it as usual.


but ! since past few days i notice that my computer getting weird when i enter sleep mode (for example closing the lid)
it crash... it bsod.

And it occur since the day after i installed somekind of VPN software and wiFI sharing that my friend gave me.
After that day, i can't put my computer into sleep. whenever i do that it keep crash.

at first , i thought lenovo energy management that cause the prob
so i uninstalled... it still makes no different , still i can't put my computer to sleep.
after that i uninstalled the vpn and wifi sharing software, it still makes no different.
But i am very sure that the vpn and wifi sharing software cause the problem.

Because before this everything works fine until that two software comes to my computer. I really need someone that able to analysis the dmp file. TQ

I willing to learn and contribute if i were given the opportunity . tq

Hi Eric & Welcome to the forums ^_^,

I have analysed your dump files and below has been provided an analysis of the same for informative purposes :-
Now, as we can see from the Dump file analysis, "tunnel.sys" has been blamed which is the Microsoft's Tunneling Driver but since it is a component of Windows, chance of it being the culprit is extremely low. This means your guess that the BSOD are caused by the VPN Software.

On checking the Drivers, I found the SoftEther VPN installed on your system. Please uninstall it from the system and see if the system still BSOD's or not.

Let me know how it goes ^_^.

Hi there, tq for ur information. The problem still occur after uninstall the vpn software. So i format the computer and it fixed the problem.

Glad to hear that the problem has been fixed ^_^.

In case of any further problem, do not hesitate to post back. Kindly mark this thread as Solved ^_^
