Windows 10: BSOD - Windows 10 - "kernel power" - sleep/hibernate issue?

Hi

Last month i bought a new laptop for my girlfriend, a Lenovo Flex 2, 14" full hd touchscreen, i3 haswell 4030. It was a bargain because it was the last available (can't go back to the store and ask a new one, only a refund). At first boot (in W8.1) the laptop already got stuck in a bootloop after filling out the primary setup info, untill i disabled all updates in the W8.1 setup settings. This and the fact that we are no big fans of W8.1 made me update to W10 immediately (as in, after start up, install the necessary updates and update 2 hours later).

However, after the update to W10, i also immediately did a "W10 reset" since i had read that would be pretty much be like a fresh install, and the fact that there seemed to be problems in W8.1, i wanted to remove as much of the 8.1 leftovers as possible.

But ever since she started using the laptop, now fully W10, it has multiple BSOD crashes every day. I have made some screenshots below. I installed all the drivers from Lenovo's website, which are supposed to be W10 compatible. I removed a couple of programs of which i thought might be offenders, like Avast, Skype and Spotify, to no avail. I ran memtest86 to see if there was a problem with the RAM, but no errors to be found. At this point, i don't know if it's hardware or software related.

We did notice that the BSOD usually come minutes after opening the screen and waking from sleep/hibernation.

I can't return the laptop for a new one because it was the last one they had, and the price was really low, so i'd rather try to fix it, than get my money back. I contacted Lenovo but they want the computer in factory settings, meaning W8.1, and i rather not have to go through two OS installations and do all settings and installing programs etc over again, So i'm hoping someone here can help me.

Below the dump files as requested, and an aditional zipfile with screenshots and the big memory.dmp file as well (i saw it was requested on the microsoft forums as well).

Microsoft OneDrive - Access files anywhere. Create docs with free Office Online.

I'm also unsure if i can go back to W8.1 through factory settings (as requested by Lenovo should i need to bring it in) after the "one month" period has passed, that Microsoft gives you to roll back the OS.

Thanks in advance

Sleep & Hibernate issues

For some time now, my computer will not go into "Sleep" or "Hibernate" mode, unless I force it manually. In "Settings" , "Power & Sleep", I have it set to "Sleep" after 4 hours, but it does not go into "Sleep" mode, and stays on until I turn off the computer.
I can put it in "Sleep" mode manually from the "Start" menu power button icon, and I can do the same for "Hibernate". There is no setting for "Hibernate", under "Settings" , "Power & Sleep". How can I get the settings to work for "Sleep", and how can I add
"Hibernate" to the "Power & Sleep" menu in "Settings"?

 

One user keeps hibernating her PC by mistake?!

Tried looking. There are entries for Kernel-Power, but none of them occur at the time of the sleep. Event Viewer does not record the hibernation at all, which makes me think it has to be the machine.... but a brand new machine having exactly the same
issue as well.. with the same user!! I don't buy it...

 

Hi ozfunghi,

Welcome to the 10forums.

There are a few causes for the dumps I have checked so far.

Starting with the Intel Rapid Storage Technology

• Search and open msconfig
• Go to the tab services
• Check 'Hide Microsoft services'
• Search Intel Rapid Storage technology service and uncheck it
• Click apply > ok
• reboot if asked

This driver is the Wifi driver (Qualcomm Atheros AR956x if you look in the device manager)
It has been flagged multiple times, but I'm not sure if it is the driver or memory corruption.

If this test comes positive (zero errors) then the wifi driver needs updating.





Diagnostic Test

RAM TEST


Run MemTest86+ - Test RAM - Windows 10 Forums



Note



MemTest86+ needs to be run for at least 8 passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

 

Note Don't forget to reset driver verifier
To reset driver verifier:

• Open admin command prompt
• Type "verifier/reset" (without quotes) and press enter

 

Hi Axe,

I unchecked the intel rapid share feature as you explained.

As i explained in my first post, i had already run memtest86 (it took over 6 hours) but it came back without any errors. Now, i know this is not the same software as memtest86+ (started out the same, but branched and one became a commercial product and one remained open source if i remember correctly). I tried to boot memtest86+ from a USB stick, but it wouldn't boot. It did work with the free version of memtest86 (without the +). Is it still necessary to run memtest86+ if I already ran memtest86? I'm just asking because it took so long to finish.

As for the driver, i installed the latest driver from the Lenovo website weeks ago... (after the BSOD started). What other driver should i try? Or where should i look for it?

Thanks

 

2 things.
1 running memtest less then 8 passes isnt worth it, how many passes did you have?
2 MemTest86+ is better and recommended

 

It could very well have been 8 passes, i don't remember exactly, but it were multiple passes, and not 2 or 3. It also took all night. I will try to run memtest86+ tonight.

I can't find a better/newer driver though for the qualcomm atheros 956x. Windows says the latest driver has been installed, on the Lenovo website i can't find a better one.

 

Well, after trying 4 times, i'm giving up on memtest86+. The program just doesn't seem to be able to create a bootable usb stick. This is the reason why i did it with the "other" memtest86 last time, which worked immediately. Tried creating the bootable usb stick on two different systems, as administrator, zipped and unzipped... doesn't matter. Won't boot. And before anybody asks, i'm selecting to boot from USB in the boot menu, obviously.

 

Please read a thread with similar problems with MemTest86+ here

 

Thanks, but the only solution i'm reading on that thread is to boot from cd/dvd... but it's a slim laptop without a dvd drive. So that's not much help unless i go out and buy an external dvd writer. I don't understand because i used the same usb stick and booted it the exact same way with memtest86 and that worked just fine.

 

Before I forget

About the drivers, install them only from the manufacturer

 

Updated the info as requested.

So it seems i'm stuck at the moment, because there is no newer driver available for the Qualcomm Atheros and memtest86+ won't boot (the laptop doesn't have a DVD drive, see previous post).

The good news so far is that there hasn't been a BSOD since i disabled the intel rapid storage tech.

 

There is a great chance that the activity of IRST was causing all the crashes.
Usually with laptops it is not needed to enable it because they don't use RAID.

 

When i wake the laptop from sleep, it is also a lot snappier and quicker now. You can feel it's not "working" as it was before for minutes after waking. Edit, to clarify, by "working" i actually mean doing stuff in the background.

I'll see if the BSOD stay gone the next couple of days. If they do i'll set the topic to "solved". If anybody still has any ideas how to boot memtest86+, do share. Else i'll leave that be for the time being, the BSOD being gone is most important.
