Blue Screen on Hibernate

[SrsAdm]

Hi,

After a couple of trouble-free year with my DELL Latitude, I've started getting crashes when trying to hibernate. Its showing DRIVER_POWER_STATE_FAILURE (9F) and produces a Mini Dump, but I can't seem to tie it down to an executable. Any help gratefully accepted. I've attached a zip with the dump files.

Thanks in Advance

Have you changed your network connection at all? New network card, wi-fi card, ethernet adapter, new drivers for them?

It is likely related to your networking. Make sure your drivers are up-to-date and go into control panel>device manager and locate your network devices and under the power management tab make sure they are set to never sleep.

Hi Thanks for the reply. I haven't added or changed anything on the networking side as its been stable for at least a year. I'll try the power settings and post a reply.

Do you use Windows Updates and have the box checked to treat Recommended updates the same as critical updates?

If so then it is very possible Microsoft updated your driver for you.

Definitely give the power management settings a look.

Hi,

I changed the power settings but its still crashing. I do let Microsoft update non critical stuff, so I guess that a driver was updated by MS, so I'll just have to go through and start removing stuff

Hi,

I've taken a look at the latest minidump and its given me a bit more information...

I looked at what used eacfilt.sys and the only thing that seemed suspicious was a Cisco VPN Client that I used to use to access a customers systems. I uninstalled this (although I haven't updated it since it was installed) and bingo! So far I've been able to hibernate without issue.

I'll keep an eye on it, but fingers crossed!

Thanks for all the help!

You can go in to control panel > device manager and look at your network drivers and see if any have a "rollback driver" available. But if rolling back the driver does solve the problem them you will need to go into Microsoft Updates and hide the update for that driver or it will keep getting installed.
