Recently took delivery of a Latitude 6430u.
Upgraded the 64GB SSD to 256GB.
Used an external CDROM and the Win 7 64bit restore CD to restore the system.
Followed the guide to re-image, etc. Installed everything in exactly the right order.
I still have a yellow triangle for "PCI Simple Communications Controller"
I have installed the chipset drivers and they installed successfully.
Any ideas?
