Windows 7 on Latitude E6400

In this case you got the newest .1872. Dell supplies the older .1855 which probably is optimized to get the brightness regulations right. On the other hand the .1872 supposedly makes the CPU support the GPU in matters of graphics calculations. That should increase your graphics performance. Haven't tested it myself, since I have no games at the moment and ain't in the mood for installing Team Fortress 2 by downloading it through Steam... takes a while...

Since the brightness regulation problem can be circumvented by closing the lid for a moment, I won't search for way to downgrade either way...

 

A good question. We face it every time a new drivers appears for download for a device that is already working OK.

I usually read the "Fixes and improvements" section of description and judge by that.

 

I just keep upgrading to the latest version... it never broke stuff.

 

I remember there was once a HDD firmware update which was harmful for HDD (Can't remember if it was for D620 or E6400). It was only up for a short time, before a fixed version was posted.

 

Yea, these once in a lifetime event, and you are talkjing about a firmware, NOT a driver, and you aim directly at the HDD.

 

I'm a stickler for staying updated with the most current firmware and drivers.

I want the best performance possbile out of my machine.

 

if you have the intel card, you get my wifi technology out of the newer drivers. if that isn't a reason to upgrade, i don't know what is. and there are currently compatibility issues with that for win7 which are supposed to be fixed with an update.

 

I am having a lot of audio quality problems on my E6400. My system specifications are P8400/X4500MHD/4GB/320GB/Intel5100.

I have installed Windows Server 2008 R2 x64 Standard on this machine (using it as a workstation), and it works like a champ barring the infuriating, frequent audio pops and clicks, regardless of the application (VLC, WMP or video in a browser) I am using.

My DPC latency also seems to be unreasonably high, averaging ~600us, with absolute max of 2300us (very rare).

I have the latest drivers installed for all components from Intel's site, and have also installed the latest version of 'IDT 92HDxxx HD Audio for Windows 7' driver (6.10.0.6217, A09) from Dell.

Any advice is appreciated. Thanks!

 

Yeah, I forgot to mention that I have already tried the following options:

1. Switching from IRRT to AHCI in the BIOS (in fact, my OS was installed with this setting)
2. Toggling Processor Scheduling between Background Services and Programs (currently on Background Services)
3. Installing/Uninstalling the latest Intel Matrix Storage Manager driver (v8.9 as of this post)
4. Praying to the Flying Spaghetti Monster, Cthulhu and then both of them together

The only thing left is to call Dell then, I guess?

PLEASE HELP!

 

Do you have any WWAN card installed? If so, temporarily disable it in the BIOS. If that doesn't work then try temporarily disabling other bits of hardware.
