News on Haswell based mobile Precision M6800 ?

No, german keyboard layout.

But do you expect the region specific layout to make any difference?
Isn't it just a different positioning of the same key parts?

 

Hi Sven,

I really think it is the Bios, because with my previous Toshiba Sattelite L670, I had a similar problem (left letters out while you were typing, the opposite actually...), which was solved after half a year with a bios update.
This also means that you don't have the problem with an external keyboard.
The Dell technician was not able to see the problem, because it rarely occurs sometimes...and then I have it 10 times in one row.
I will contact Dell again tomorrow (then I have the buisiness desk, which is a lot better) and will let you know the result.

 

it's something that happens when on windows and using the international keyboard layout. yours seems to be another problem entirely though, sorry

does anybody else have a problem with the fans? they make a weird noise once they spin up, almost as if they hit something. sounds a bit like a 'click', or like they start up too hard (just on start-up)...

 

No, I do not have that.
Did you take a look at the fans to see if rotating them manually touches anything like a cable, which could be brought out of the way?
The chassis bottom can be easily removed which lets you look at the fans at least from the bottom side.

 

Yes, I also have this problem so yours is not a pure coincidence. It's nice of you to share how you are to solve this. (I moved to a new home and don't have a screwdriver so far. Will try myself when I have)

EDIT: after opened the back cover, I found nothing wrong with the fan. Nothing blocks the fan and there is no additional resistance on the problematic fan compared to the one which is not noisy. However, the noise is still there.

 

New theory: it is caused by changed key press default delays in Windows.

This thread got me started: Studio XPS 16 - Keyboard Issue / Duplicate Characters - Laptop General Hardware Forum - Laptop - Dell Community

I just turned on the mentioned "Filter Keys" in "Ease of access keyboard settings" (Press <win> and type "ease of access" to find the option.
Turn key filtering on. That "disabled" the keyboard almost completely, especially the control keys like <win> and <alt>+<gr> did not work for me at all anymore - seems they are implemented as multi key sequences which get filtered... Just *disable* "Filter Keys" to get back to the default setting to stop duplicate letters. It seems the default without ever touching that option is a different one than toggling it on and off again.

I typed this all without a single duplicate - how cool.

Problem seems the will to make the configuration of keyboard params easier. If anyone needs more control, the values to play with are here:

HKEY_CURRENT_USER\Control Panel\Accessibility\Keyboard Response

Flags change between 126 to 127 when Filtering is toggled. The repeat/delay/bounce settings might be the key to optimize the behavior for the own typing style.

HTH anybody else who has this problem, too. And many thanks to HAL-9001 who inspired the work around ;-)

 

Anyone who has K4100M or K5100M, could you share your vBIOS file with me please? I am making my own vBIOS. You can easily get it from GPU-Z.0.7.5. Many thanks.

 

Does anyone know what the m6100 is based off of?

My m8900 took a crap and dell is replacing it with a m6100....


Just going by amd specs it looks like it is a desktop r7 260?

 

HWINFO64 at least identifies it as AMD Radeon HD 8950 (Saturn XT). Linux also identifies it as Saturn XT based. So far I haven't managed to make it work in Linux so if anyone has managed to do that I would be interested to hear with what drivers.

 

Maybe related:

• Ubuntu's site implies Dell supports Ubuntu for this configuration.
• Dell's M6800 drivers page has an update for Ubuntu 12.04.2 released on 2014-01-10, at least on the US site.
