AC-9260: The miniport has failed a power transition to operational power

[KThef]

HP AY168SA, stock configuration with replacement wifi card & clean install of Windows 10

Using the latest Intel PRO set drivers (March 20).

Using latest HP BIOS & drivers.

With secure boot turned on, the error is very inconsistent and the event log shows a variety of obscure error messages.

With secure boot turned off, the card fails to initialise with "The miniport has failed a power transition to operational power" (followed by a variety of assorted error messages) after the machine has been in stand by. restarting the machine brings the card back online. Uninstalling and reinstalling the card, or disabling it, causes the machine to hard reset.

Hello!

I've tried configuring the power management as suggested, this seems to have had little effect.

Furthermore, sometimes when the wireless deactivates, it will not re activate even if I pull the battery, press and hold power button, etc - so in a way it might be worse now but this could all be down to random chance as the problem is reasonably inconsistent to start with. Sometimes it will suspend / resume or turn off / on without issue, sometimes not.

The device is definitely remembering it's previous state when powered down but I can see no pattern other than that it is definitely related to powering the device off and on. The problem will not occur if the laptop is not turned off. I have used it for 30 hours straight with zero problems, closed it, re opened it, and then had no wifi.

Cheers!

Hello kimthefirst,

Thanks for your reply.Checking the http://h10032.www1.hp.com/ctg/Manual/c05087748 Maintenance and Service Guide for your system (page 62), we noticed Intel® Wireless-AC 9260 is not part of the recommended spare WLAN modules.As explained before, it is highly possible the issue is caused by compatibility. At this point we recommend https://support.hp.com/us-en/contact-hp contacting HP* for further assistance.NOTE: Links to third party sites are being offered for your convenience and should not be viewed as an endorsement by Intel of the content, products, or services offered there.Best regards,Eugenio F.

Dear Kimthefirst!

Have you found a solution? I have almost the same problem.

The difference is that my Intel wifi adapter is in recommended list of wifi modules of my HP pavilion laptop.

Many thanks in advance!
