I have a Dell vostro 5590, which overheats under Kubuntu 20.04 (the CPU cores reaching 90+ degrees regularly, so is the package temperature, fans working often at top speed).
I currently have BIOS version 1.8.2, and I have seen here that the newest version is 1.11 (from the 1st of September 2020). Thus, I hope that if I upgrade my bios to the newest version, it will be fixed.
In this article, Dell are suggesting to create a blank bootable device, and to move the bios-upgrade
.exe file to it, booting into the bios (using F12) and updating.
This far, I have tried to create a live USB using:
KDE partition manager, deleting all partitions and making one partition using FAT32.
rufuson windows to create a bootable device using freeBSD (a long shot).
diskpartaccording to the steps here changing from ntfs to FAT32.
So far, when I reach the bios, it doesn't seem to recognize this as a bootable device, in any of the cases above, and when I'm trying the "Upgrade BIOS" option in the BIOS, I get nothing (no option to choose a file or anything active...).
Remark 1: from the same USB I was installing Kubuntu 20.04 on this machine, so it is working, checked it out before this process.
Remark 2: I have the
dell recovery utility on another USB drive, and it recognizes it, and even boots into it.
