Just got my AMD 7840u batch 5 delivered today, out-of-box experience was so nice. Took less than 30 mins to assemble.
I replaced the thermal paste with a Thermal Grizzly Kryosheet graphene pad after taping off the capacitors with kapton tape.
Swapped the Wi-Fi card for the Intel AX210 just in case to prevent any funny wifi or driver issues with the mediatek.
Installed Linux Mint and switched to the 6.6.1 mainline kernel, so far so good.
96GB RAM works fine out of the box at 5600.
Ran “stress -c 16” for 30 minutes, CPU temp didn’t go above 80c.
Laptop feels super premium, trackpad and keyboard feel better than I was expecting. There’s a little screen wobble as expected but it’s not too bad.
The fingerprint reader took a little fiddling to get to work, I’m on Linux Mint XFCE.
When I tried to use fprintd-enroll I got the error that the firmware needed to be updated, but when I ran fwupd it said there was no new firmware so I had to follow this thread to fix it: https://knowledgebase.frame.work/en_us/updating-fingerprint-reader-firmware-on-linux-for-13th-gen-and-amd-ryzen-7040-series-laptops-HJrvxv_za
Then once I was able to use fprintd-enroll to add my fingerprints, I had to do apt install libpam-fprintd and follow these instructions to get the lightDM login and su and sudo to use fingerprint: https://wiki.archlinux.org/title/Fprint#Login_configuration
Now it’s working properly.
