Windows 7 on Latitude E6400

E series owners used to complain about latency problems, but the newer drivers seemingly have eliminated most, if not all, of these problems. There is a long thread on E series latency here on this board. Just do a search for it. I would say don't worry about it.

 

take a look at the changelog provided by intel, but it solves a lot of major issues, including hangs, etc. and it is also better in terms of the dpc latency. edit, even dell has it up now.

 

Thanks. Under E6400, Vista 64-bit, SATA Drives, the Dell Drivers and Downloads page lists two Intel Matrix Storage Manager-related downloads, both dated 23 April 2009 and having a Level of Importance of "Urgent": an application and a driver. The Fixes and Enhancements for both files simply states: "This release resolves an issue where the user may hear interruptions during Audio/Video playback." Is this what you a referring to? The instructions for both files make no mention of one another; should they both be installed?

Windows 7's Device Manager indicates that everything is fine on my system. I'm also not aware of any performance problems. So I'm not sure what benefit installing these items would bring to me.

 

FYI to those following my ramblings:

Uninstalling the Security Manager did *not* break the fingerprint reader. I was *sure* that the fingerprint reader would break--after all, it *didn't* work until I installed the Security Manager.

The only perceived change of uninstalling the Security Manager happens at boot time or when the desktop is locked; instead of the user name and password prompt, a message appears stating "Press CTRL + ALT + DELETE to unlock this computer"--as though the computer were part of a domain (it's not). Pressing those keys results in the normal user name and password prompt appearing. Interesting side-effect.

I wonder how these results are affected by TPM. (I'm not sure, but I believe that TPM has to be enabled in the BIOS before the fingerprint reader will function. Does anyone know whether that is so? Do E6400 users here typically enable TPM?)

 

Sorry, if these were answered before. It's a long thread, plus I imagine that they're going to be common questions:

1. Can I upgrade from 32 bit Vista to 64 bit 7?
2. Will I have to download all of the drivers if I do?
3. Will I have to download the drivers if I stick with 32 bit?
3. If yes, do you think it's worth it or should I stick with Vista or 32 bit 7?

I have 4GB of RAM by the way

 

you cannot upgrade across architectures. If you stick with 32 bit, you shouldn't have to update any drivers. you should use 64 bit, especially if you have more than 3GB of ram. and even if you don't, it is still a benefit.

 

Win7 x64 loads all the drivers except the Broadcom USH. You may also want to install DCP system manager, and that's about it.

If you stick with 32bit and do an upgrade, then you don't need to install any driver or program.

 

I'm sorry if I didn't quite understand. I think you're saying that I'm going to have to install 64 bit from scratch. It still might be worth it, but it's going to be a pain in the butt.

 

Nha. 20-25min to install Vista/Win7 64-bit.

 

Installing win7x64 or x86 is pretty easy, since almost all the drivers are installed automatically. And there are very few updates. The pain is in reinstalling all your applications and loading all your files.

Installing a new Vista OS is a royal pain-in-the-butt, since you have to install all the drivers, the updates and then stuff like language packs.

Been there, done that, many times.
