I just installed Win 7 on my XPS13 L322X and have everything working with these exceptions:
1. The A15 BIOS update fails with “Unexpected error, please reboot and try again” Code 0x00000207. I have downloaded it twice and saved it to the desktop but same error occurs. I currently have A10 running. 2. Two devices still do not have drivers after I followed all your steps: – Intel 7 Series/C216 Chipset Family USB 3.0 Extensible Host Controller Installation Disk – 1E31 (hardware ID is DEV_1E31) – Unknown Device (Hardware ID ACPI\INT33A0)
Can anyone identify drivers for these?
Plus I have a trivial issue with my Inland Bluetooth mouse: I can’t get it into Discoverable mode to pair it with the XPS13. It shows up in the Bluetooth Devices pane but it doesn’t work. Any ideas?
Currently the latest BIOS available for Dell XPS 13 (L322X) is A10 version. I would suggest you to install all drivers available under chipset section to fix the issue. Please enter your service tag # on the link below, select the OS, then download the chipset driver from chipset section onto the system and install it.
