NP8662, win 7 x64, Constant 10% CPU usage, fingerprint reader

Hey guys

Finally got my 8662, and apart from two dead pixels (such is life, I guess... and I didn't get the dead pixel warranty) which came up on the last couple of days, everything is great.

However, I'm having this issue which I'm not sure is entirely normal. The WUDFHost.exe process is using a constant 10% of my cpu.

I used process explorer as suggested on the win 7 forums to find out what that process is doing or which dll's it's calling and after some digging around I found out it's constantly calling tcwbf.dll, which after making a search on my hard drive comes up as being part of the UPEK set of drivers for the fingerprint reader.

So my question is this, those of you running win 7 and using your fingerprint readers, do you also get this constant 10% cpu usage, or was something screwed up during my driver installation?

When I first installed win 7, it recognized the fingerprint reader from the getgo and installed some drivers. Afterwards I went and downloaded the protector suite 2009 for win 7 and installed it in order to be able to use it.


Did I do something wrong, or is this the way it's supposed to be?

 

Did you install specific drivers for this, or is windows using some sort of generics? Obviously you want to use the latest, specific drivers, assuming they're available. If that's what you've done, I'd try different versions of the drivers (older ones).

 

" apart from two dead pixels"

I have read here in NBR ( I will search and see if I can find who exactly it was, but I do know it was a Clevo owner with lots of posts that I respect or I would not remember) said that he messaged or rubbed his dead pixel out.. also I think there was some software loading re-loading to stimulate the spot..

Sounds kinky.. but it worked.. I think that you may have a shot at fixxing the pixels is my point and I hope this helped. I will edit after I search if I can find exactly who it was..

Be well and nice rig, JW

This is not what I read but maybe helps as well.. http://forum.notebookreview.com/showthread.php?t=103404

more to follow if I can find it.. http://www.notebookreview.com/searc...FNT:666666;GIMP:666666;FORID:11&hl=en&x=7&y=8

Sorry I could not find the exact post I wanted but here in NBR is a TON of good info.. I hope theis helps.

 

wow thanks a lot JWnFL! I hope it works! +rep!


and Brandon, thanks for your reply. I think I'm on the only win7 drivers upek has made so there's no way of trying out other drivers.

 

Damn it! how often do people get dead pixels with there new 8662? i hope i dont get any.

 

I didn't get the warranty and I didn't get any dead pixels. So the stars do align, and I believe quite often since I've read a lot about the NP8662 on the forum here and it is rare to hear a complaint about dead pixels.

Good luck

 

rivehn: None for me either. Usually you only hear from the few that have problems, and not the many that have none.

rsm86: I'm running 7 and I don't have the same problem. I don't use the protector suite though. I just updated the fingerprint driver and use the features built into 7.

I did have a similar problem before, but for me it was windows media player connecting to the internet, or something like that. I googled around for the answer. You should do the same.

 

Thanks for the replies both of you.

 

I also am using the protector suite 2009 for Win7x64 but I don't have that problem. Try reinstalling them?

 

will do, thanks

 

Why didn't you return the laptop rsm86? Sager let's you give back the lappy anytime for any reason before 30days after the purchase. So you call them and ask for a replacement screen, and if they say no you return it and get another one.

 

because it took about 3 weeks just to get here, and i need it for school work. Plus shipping to and from costa rica is expensive!

 

I was just in Liberia man, coulda brought it back for you..

 

oh man you shoulda let me known! haha. Liberia is like 5 hours away from me though


so anyways, in case anyone ever runs into this problem: I uninstalled the protector suite 2009 and upek driver and now no more 10% constant cpu usage (strangely enough though, I can still log on to windows with the fingerprint reader, so I don't think the driver uninstall stuck... the protector suite however is fully gone).
