Synaptics causes BSOD on P650SE

Yes I've said it many times now, Clevo Control Center (Hotkey) is the cause.
Remove it completely including any folders and BSODs should stop, otherwise format and don't install it again.

Hotkeys should still work, they are working for me.

 

I was able to use the Fn key when I uninstalled CCC, but my headphone port stopped working.

 

My headphone port still works after uninstalling CCC, maybe you should try reinstalling sound drivers.

 

My port didnt stop working at first. I think it happened after I had put the system to sleep and then did a restart later on. I tried uninstall and reinstalling both the realtek and the creative drivers when it happened and neither fixed the issue. The only way I got the headphone port to start working again was to install CCC.

Edit: And by not working I mean no sound would be played through the headphones. Realtek would know that I plugged a device into the port and it would stop playing through the speakers but no sound would come from the headphones.

 

As I wrote before, audio port doesn't work after a deepsleep if hotkey driver is not installed. There's a dll in this software that redirect audio every time.

 

You are right. It doesn't work after a deep sleep.

 

As a few people in this thread have mentioned, HotKey - specifically, the filter driver HkKbdFltr.sys, is exactly the problem causing these BSODs. Removing or disabling the driver directly causes your keyboard to go completely unresponsive within Windows (and mice experience the same loss of functionality with the removal of the equivalent mouse driver HkMouFltr.sys). These drivers persist even if you uninstall HotKey.

The solution I applied was first removing HotKey (the application - just use the Control Panel's Add/Remove programs option), and then reinstalling Windows 10. The "system refresh" option, which deletes apps, reinstalls drivers and such, but leaves your files alone, works just fine for this. This will reinstall your keyboard and mouse drivers without installing the OEM's extra drivers. This will delete all of the applications you have on the same drive as your Windows 10 installation, so it can be a hassle if you've been using your computer for a while like I have, but Windows keeps a list of all removed apps so you can find them again pretty easily. Also, if you happened to install a bunch of your apps on a different drive, you can keep all of those.

As you can see, the end result is that HkKbdFltr.sys is gone, and I still have the use of my keyboard.


(The extra driver is some harmless-looking thing that shipped with Avast, you should only have the bottom three post-reinstall.)

I actually still have all of the hotkey functionality that my machine shipped with, including the touchpad disable control - there's just no informative popup for these, since that was part of Clevo's HotKey application. More importantly - no more BSODs! I can finally get through a few rounds of CS:GO without worrying that my keyboard driver will blue-screen my laptop in the middle of a defuse.

Hope this helps other folks with this issue!

 

A week ago I found the same issue many here found after a sudden crash & reboot of Windows 10 on my P670 whilst in a game. I read most of this thread before deciding to remove the Control Centre, and there had been no crashes or reboots since.

However there are other issues related to removing the Control Centre. Notably, the headphone jack doesn't work. And it's also a little more annoying to switch between the discrete or hybrid mode graphics.

So I've found a way to keep the Control Centre, but prevent the loading of the HKKbdFltr driver which is causing the issues. The driver is installed as a filter on the device, and it's pretty simple to remove it via regedit while leaving everything else as is.

To stop the driver loading, find your devices in regedit through a search for "HKKbdFltr" and "HKMouFltr" ( if you want to remove the mouse driver too ). Mine were found here:

Keyboard
HKLM\SYSTEM\CurrentControlSet\Control\Class\{4d36e96b-e325-11ce-bfc1-08002be10318}

Mouse
HKLM\SYSTEM\CurrentControlSet\Control\Class\{4d36e96f-e325-11ce-bfc1-08002be10318}

In each, you should see a UpperFilters entry. Simply double-click and remove the appropriate hk ( HotKey ) driver line. Don't change or delete anything else. Once you reboot, they should no longer be loaded. Here's mine now:



And I've been writing this listening to music through the headphones again.

 

Thanks, I just tried it, and I managed just about. However I found the mouse and keyboard filters to be in the same place, even when I searched specifically for them, so only had on hk line to remove not one for each. Hoping it works!

Update: this has been working for over a month now, I think that for the problems I was having (DRIVER_IRQL_NOT_LESS_OR_EQUAL SynTP.sys BSOD, and the BSOD blaming hkkbdfltr.sys) then Sammy34’s fix is the best option, I have had no problems or consequences to this fix other than the BSOD’s ceasing to affect me.

 

Is it still working for you?

 

Yep, still working perfectly after a month or so.

 

I uninstalled my touchpad driver and that fixed it for me.

 

I've been getting some BSOD's on my W230SD with the error:
AV_SynTP!unknown_function

I've gotten it about 3 times in the past week according to the W10 Reliability manager.

I used the above regedit to disable the keyboard filter, and will update here in the future and report if I'm still getting the error or not. But also, thanks for the info here, great resource.

 

Did you lose any functionality (gestures, for example)?

 

It still works, but without gestures. Windows 10 keeps insalling those Synaptics drivers back tho.

 

Guys, while reading the full thread it seems there is no definitive solution for the problem yet, am I correct?

 

Seems like most of the issues lately have been tied to the control center program. Not 100% of the time, but lately it seems to have helped others. Could also try removing synaptics, or doing a clean install, to see if that helps though.

 

I see. You should be able to prevent that; see Disable Automatic Download of Drivers from Windows Update (a little more than half way down the page), found here: http://www.howtogeek.com/223864/how-to-uninstall-and-block-updates-and-drivers-on-windows-10/

 

I've found that downloading the version of control center for your specific notebook from Sager's website works best. The company lists version 5.0000.0.6 for my NP9772, and that's what I will stick with after newer versions caused problems.

 

Generally, the drivers/software on the manufacturer's site are the ones they have tested and approved. A good amount of issues I've seen can be resolved by using the drivers from the manufacturer's site.

 

Sometimes. The problem is that most OEMs don't update their drivers with anything approaching regularity.

In Sager's case, the audio, chipset, GPU, Intel ME, and other components are very outdated. With all of these, the updated version from the specific hardware vendors are much improved.

 

They are designed to give you a known base to work from.

 

you mean to say, always go to Intel directly for your drivers etc.. get the latest support. Problem is many trackpads have issues and there is no fix anywhere for windows 10.

 

Right, and I get that completely. If you might be having an issue while using the newest drivers, then it might be worth trying the ones that are on a manufacturer's site. Not to say that new ones won't work, but there are some cases where using the ones listed for your model might be the most stable.

 

Have Manufacturers a dialogue with Microsoft about what they can or should NOT do, so Win update don't push out newer drivers that create instability on their customers' computers? New isn't always best although the Redmond Morons mean they can best. OEM's must demand that Micro$idiots don't push out newest drivers for their specific models hardware if the OS users don't want them or the manufacturer haven't tested and verified that they work as intended.

 

You can turn off automatic driver updates in your system settings. You'll have to manually find all drivers, but it is doable.

Yeah I know all that, but there are people who can't much about computers. It's a damn duty that OEM*s have a dialogue with the Redmond idiots. If you create computers so either test all new drivers and see that they work as intended / make your own or stop Microsoft genius idea to push out crap.

 

This is why we have forums. While users wait for things to be hashed out behind closed doors, as frustrating as it all might be, there is, at least, a helpful community having their own dialogues.

 

I found sammy34's solution on page 16 of this thread to fix my problems entirely with no side affects.

 

will this work for a ETD.sys as well which is like the trackpad on some other clevo's ?
NP9177 or P177 series gives me this issue always.

 

It worked in P370EM

 

I don't know whether this is still relevant, but I fixed this problem on my P650SG by installing the drivers from Synaptics' website. No more BSoDs related to the touchpad ever since install a couple of months ago.

 

Do you have HotKey (Clevo Control Center) installed?

 

Yes I still have it installed all the way without any other modifications.

 

Hello all.
I have same problem with syntp.sys bsod, but my pc is p650rp6-g. Can i try this solution as well?
Thanks.

 

Yes. It even fixed my P370EM3

 

Thank you! I'll try.

 

Isn't EM from 2012? Wow.

 

Yes it is. Drivers are not.

 

Thank you for sharing this! My P950HR have this BSOD for the first time ever today, and lets see if BSOD will still occurs after the fix.

 

I dont fully understand what to delete.. Here are screenshots please tell which line exactly to delete?
https://yadi.sk/i/VcHD0Sw73MgyqW

 

No image displayed. Can you attach it here, or post it inline?

 

I can see ur print. U just need to delete HKKbdFltr, dont touch the others. I also removed the mouse too, HKMouFltr. No more syntp.sys bluescreens

 

edit fixed

 

no more bdos but with this fix they keyboard's hotkeys don't work anymore.. i mean if you try to register an action with the keyboard using flexikey, it will record the action but when you play it, it won't reproduce it

 

Do you know a way to fix an unresponsive keyboard and mouse due to removing HkKbdFltr.sys and HkMouFltr.sys? Because now I can't log in or press f8 for startup settings

 

My keyboard and mouse are now unresponsive from deleting HkKbdFltr.sys and HkMouFltr.sys. I must have deleted it the wrong way because I can't log in or move my mouse. Is there a way to reverse what I did because I can't press f8 for startup settings due to my keyboard being unresponsive

 

If anyone needs a fix for this issue here is a .reg that already has the fix done!

All you need to do is add to the registry and reboot!

Syntp BSOD fixed!

I can confirm this fully fixes the problem. I used to have BSODs daily and it's been more than 1 month since I did that and NO more BSODs at all. Thank you

 

Yesterday HKKbdFltr BSOD happened for the first time. I will try this solution, but instead of refreshing Windows, I will try using Revo Uninstaller to delete CCC.
