Windows 10: WIN10 BSOD on lenovo yoga 920

hello all,


When my notebook gets off sleep mode, it, almost every times, crashes.

It then generates a minidump file.


this is the summary from the crash


DRIVER_POWER_STATE_FAILURE

caused by driver : WUDFRd.sys

caused by address : WUDFRd.sys+fbf4

crash address : ntoskrnl.exe+198430

my win10 is up to date, and memory is fine (checked up by win10 utility).

sfc /scannow is ok also, and every thing seems uptodate (although i'm not sure on how to check that all drivers are up to date)...


As no driver seems to be directly pointed by bsod minidump, could you give me an hint on how to analyse the dump, if there is a way ?


thanks (im more a linux guy than a windows guy, so im not sure where to start).

:)

 

Lenovo Yoga 920 / Qualcomm Atheros QCA61X4a -- slow wifi


Hi Krib,

Not sure why your Yoga 920 is acting up but if you've got Lenovo Companion you could open it and click System Update to see if there are any drivers for the Wi-Fi card. I'm running a 2017 Lenovo ThinkPad X1 Yoga and have no Wi-Fi issues. The laptop is running Windows 10 Pro. with the Fall Creator Update (1709).

Anyway see if there are any drivers for that laptop and go from there.

Lenovo Launches Yoga 11S Convertible

Lenovo announced that customers can place orders for the IdeaPad Yoga 11S beginning today on www.lenovo.com or pre-order on www.bestbuy.com. The acclaimed 360° flip and fold Yoga 11S premiered in January at the International Consumer Electronics Show, following its popular predecessor, the IdeaPad Yoga 13.

Sized well for mobility in a thin, 11.6-inch design, the Yoga 11S Ultrabook convertible comes with choices of a powerful third generation Core i3, i5 or i7 Intel processor giving consumers the ability to create high-performance content and presentations and seamless graphics that make it a great entertainment device.





Yoga in Four Modes
Yoga converts into four special modes to fit the changing ways people are using technology. It offers a new way to experience mobile computing, letting people define which mode works best for them in their environments, from the park and the coffee shop to in transit, at home or at the office.

For example, users can watch movies like never before by putting Yoga in tent mode while enjoying the convertible's rich Dolby Home Theatre audio. They can convert Yoga into stand mode for a different environment; good for things like swiping through family photos using the high definition IPS screen's 10-finger multitouch support. Yoga even supports hand gestures so consumers can just wave their hand in front of the webcam to instantly advance photos, videos and other content.

In tablet mode, Yoga makes exploring Windows 8 apps fun and up close with its 11-inch touchscreen. And in laptop mode, Yoga offers a great typing experience with its comfortable and responsive keyboard. Additionally, the Yoga 11S has a soft-touch exterior and comes in attractive Silver Grey and Clementine Orange colors.

"Consumers around the world loved our first Yoga for its unique flip and fold and multi-mode design," said Jay Parker, president, Lenovo, North America. "We're continuing to develop the Yoga franchise with the new Yoga 11s, and due to Yoga's popularity already, we've created a pre-sale program so customers can get their hands on one before it even hits the shelves."

"The IdeaPad Yoga 11S is a great example of the commitment Lenovo is making to continued innovation with Windows," said Jordan Chrysafidis, vice president, Worldwide OEM Marketing, Microsoft Corp. "The commitment is evident in its beautiful hardware designs that exhibit flexibility, mobility and extended battery life; combining that with the new touch capabilities of Windows 8 provides an experience that is sure to delight customers."

"Lenovo continues to deliver on its reputation for innovative Ultrabook designs and experiences that people are hungry for with the new IdeaPad Yoga 11S," said Navin Shenoy, vice president and general manager of Intel's Mobile Client Platforms. "We created our new line of low power 3rd gen Core processors for products like Yoga, to give people a full PC experience in thinner and lighter convertible designs."

Beginning today, customers can place orders on www.lenovo.com and www.bestbuy.com. Models will be available in Best Buy stores starting on June 23. Multiple configurations will be available with suggested list price starting at $799.99
