When I started this process of driver updates, I had no internet access on the laptop, and at that point I had not tracked down the list of "install things in this order". So, I installed the "Intel Chipset Driver" from the list of options:
https://www.dell.com/support/home/us/en/04/product-support/product/precision-m6400/drivers
Then I tried to install the "Intel Mobile Chipset, v.9.0.0.1009, A00" but got warned that these were older than already installed so I exited that setup.
Then, since I have the laptop currently hard wired to the modem, I installed the Network "Broadcom 57XX Gigabit Integrated Controller, 59XX 10/100 Ethernet Controller, v.XP v10.85 Vista v10.100.0.0, A00" controller.
This gave me internet access..... which is when I tried to get any Dell Automated Support working..... all of which failed.
It was then that I tracked down the list of "install driver order" and started working my way down the list.
Next I back-tracked and installed the "Dell System Software Utility", but since then I tried to stick to the list. There was no "Accelerometer" to be found.... so I skipped that.
For each install I've done as much reading as possible and/or checking the "unknowns" in device manager for the actual device info.
At this point, I really want to get the graphics driver issue resolved, but nothing seems to work. Device Manager says I have a "Standard VGA Graphics Adaptor" installed and working fine, but the display is poor..... XP doesn't have my nVidia FX3700M on any listing...... and I can't use the drivers I've tried from Dell or nVidia.
I'm also quite certain that none of my .NET Framework updates will get rid of that damn "Inventory Collection Failed" message when I try to install the Dell Display Drivers..... but it does give me something to play with!
Sucks to be me!
Hope you're having a nice day..... :b
