I recently managed to upgrade the Framework to the 3.03 firmware update, but now when the laptop sleeps I get the dreaded ‘no boot device’ BIOS error.
My Framework 16 has a Lexar NM790 and a WD SN740. The Lexar firmware (12xxx on purchase) was the thing causing the issue, not the WD one. I upgraded the Lexar drive to 16949 and all was well. You need Lexar DiskMaster to do the upgrade (not a dissimilar app from WD Dashboard)
I hope this helps someone else with a Lexar drive!
