Dell Laptop TPM Issue
I have a work laptop, Dell Latitude 5480. After a trip to a remote office I was using it on the train back and it didn't shut down properly, resulting in the battery running out. Ever since, the laptop shows ‘Alert! TPM device is not detected!’ when powered on or rebooting and I have to press F1 to get it to continue to booting Windows. This had been going on for a while and the potential solutions I found for this that I found online involved disconnecting the battery for a while, which I didn't really want to do. Today I found this suggestion using the BIOS recovery process and it worked for me:
- Power down the laptop and disconnect the AC power
Whilst holding down the Ctrl and Esc keys, plug the AC power back in
- The laptop boots into a BIOS Recovery screen, with a few different options
Let go of the Ctrl and Esc keys
- Select the "Reset BIOS Settings to Defaults" option
- Click "Exit"
After doing this, I had no more TPM warnings when booting and TPM 2.0 was visible in Windows security settings.
Fedora Project
Updated perl-Unicode-UTF8 to 0.64 in F-44 and Rawhide:
Unicode::UTF8 now allows noncharacters; they receive no special handling and are processed like any other code point
According to Corrigendum #9, noncharacters (the values U+nFFFE and U+nFFFF, where n is from 0 to 10^16, and the values U+FDD0..U+FDEF) are permanently reserved but should be allowed in interchange
Local Packages
Updated perl-Unicode-UTF8 to 0.64 as per the Fedora version
