I upgraded my 1240P Framework Laptop 13 with a 7840U mainboard, 2x 16 GB of DDR5-5600 from Crucial, 2 TB Solidigm P44 Pro, a 61 Wh battery, and a fresh Windows 11 install. I have the following issues that I believe the community might be able to assist with.
On BIOS version 3.03, my Framework has problems with some chargers, and I detailed the issue here.
USB Powered Portable Monitor
I own this external monitor. With my 1240P mainboard, I can output display and power to the monitor simultaneously via USB-C. With my 7840U mainboard, I can either output display or power to the monitor, but not both simultaneously via USB-C. I have confirmed I am using the correct ports (I’m using the rear left port and tried the rear right port). I can, however, output the display signal while receiving power (when the display is powered with an appropriate USB-PD charger).
External NVMe Enclosures
I own two USB 10 Gbps external NVMe enclosures A and B. These worked fine with my 1240P mainboard when paired with this SSD. However, neither of these enclosures works on my 7840U mainboard. They receive power, but the SSD is not detected. I have verified the enclosures and SSD still works with my Windows desktop PC.
Can’t help with solving the issue, but I’ve got the same mainboard and use a different enclosure without any issues. I also tested a different portable monitor that we had at work which worked fine. So I can at least confirm that USB-C monitors and NVME enclosures should work.
I am on Linux though, so it’s possible that maybe Windows has some problem with them, but it’s probably worth contacting Framework support if you haven’t already, as it seems likely that there might be an issue with the board, or maybe those particular devices do something the firmware wasn’t expecting or something like that.
