Latitude E6400 Owner's Lounge

Windows can get confused. I would uninstall both and then let Windows search for new hardware.

The driver might be the Ricoh R5C847. There is nothing else in the E6400 downloads (it might be part of the Intel chipset).

The SD card reader does not use a proprietary driver. Windows loads a generic one for it. I recommend the same as John. If it doesn't work, try reinstalling the driver in Windows Safe Mode.

If it still doesn't work, reinstall the chipset driver; it controls the USB hubs and the card reader is an USB device.

 

Thanks John and Vikram, that seems to have done the trick (I didn't need to reinstall the chipset driver).

+rep to both

EDIT: can't rep you again yet John. You've been too good for me lately. Be mean for a change

 

The feedback here that the problem is solved is enough to keep me happy.

John

 

Alas, it's not. Upon another reboot the same problem arose again.

I will now reinstall the chipset drivers. Should I do so in any particular order? I was thinking of doing the following:

1) Uninstall both "SD Host" devices from the Device Manager
2) Reinstall chipset drivers from Dell website
3) Let Windows search for new hardware and install whatever it wants to

Is this ok?

 

This seems fine. Keep in mind that you may have to reinstall the IDT audio driver if you experience any problems. I usually do that.

 

I'm using the Vista sound drivers, I get more volume that way. Thanks for the tip though

 

What kind of "fancy effects" are "harder" for this GPU?

Where did you get proof that the image quality over VGA with the Quadro is better? Also, Photoshop CS4 uses OpenGL, not CUDA.

What does this mean? Of course the driver layer supports calls from the software.

I'm not here to "challenge" anyone. I just wanted some clarification.

Thanks!

 

If that doesn't work then it may be time to search the Microsoft KB for SD card related bugs. Is the Vista the original Dell installation or your own?

I can't say, because I did not test them all (there are kinda too much of them ), and it depends how they are made, and probably other stuff into the mix (I never programed games, only applications). I need to install MANY MANY games to try and analyze all this. But what I know is that I can put MY games (the Witcher, Far cry) with better quality settings (more polygon) without seeing as much performance drop as if I add higher quality shadows, lightning and stuff. For example, in the game The Witcher, I can put max texture, max number of small animals (3D objects) and I don't see any VISIBLE drop in fps in the game than if I put the lowest settings on these. But if I increase shadow or lighting to even medium settings (in these 2 specified games)... where my old Geforce 6600GT didn't show much difficulty. However, it MUST be considered that these games are simply not optimized for the Quadro/Quadro on Laptop video cards... But what is for SURE is that, the video is design to render a lot polygons and apparently Anti-aliasing (and some other effects not usually used in games) for CAD type of software. If you look at the Windows Index Experience, the Aero desktop score is lower than it's calculated gaming performance... which is something that doesn't make sense for standard gaming video card (its usually the contrary or the same values)

Here is a documentation from Nvidia: http://www.nvidia.com/object/quadro_geforce.html


Apparently by installing the Geforce drivers instead of the Quadro a gaming performance boost will occur. Which does for me when I installed the Geforce drivers over the Dell's ones. I still see the Quadro as being a Quadro despite installing the Geforce drivers... it's probably a firmware or GPU tweak type of thing. I need to look more into it.

I tried it with a friend laptop with the Intel 4500HD... but the different is, as i said, is slim. Using the same VGA cable, the Intel shows sort of vibrartion onto the image when you have 2 lines close together.. like you see on my laptop with either video cards when you look at the background of country in http://www.speedtest.net/
On higher resolutions (1600x1200), you can see the Intel video card being a tiny bit more blurry over the Nvidia card. That is what we concluded anyways. I understand that this is not a viable test, because the best way is to use the identical laptop to ensure it is not a question of interference. but considering that the motherboard manufacture is the same, and that the laptop brands are the same, it could be concluded it is most likely not an issue. The laptop that was tested was the Dell Studio 15 with the Intel 4500MHD video card using a high-end 17inch NEC CRT monitor at 1280x1024 @ 85Hz, and 1600x1200 @ 85 and 75Hz.

Yes sorry about that...
Adobe presented it's next version of Adobe's Photoshop at NVIDIA's Editor's Day. And promoted to run some things under Nvidia GPU at several evens including that one. Adobe never talked about ATI or other video cards other than Nvidia's. And heavy rumors was speculating it would see CUDA. I don't use this software at all. My apologies again, I was miss informed. Thank you for correcting me.
