I wasn't fully convinced these problems are due to the battery. That's why I listed the four things I found "odd". On the other hand, I recall hearing and reading that the output of lithium batteries is almost flat (better than any other type of battery), but then very quickly drops (faster than any other type of battery) as it reaches end-of-life.
Back to diagnosing the real cause of the problems... Is there a Fedora command that I can use to check the hard drive (not the file systems) for bad blocks, sectors, tracks, etc? Is there a Fedora command that I can use to check the controller? Both problems occurred immediately after doing a "dnf upgrade". What is that telling us? Does "dnf upgrade" access the hard drive or the controller in a way that normal daily use does not? Is there something different about the first boot after a "dnf upgrade" vs other boots? I shut down every night, and boot up every morning. When I bought the system 4+ years ago, I bought separate parts. This is a DIY desktop. I was advised to buy more power supply than needed. I did so. So unless the power supply is failing, I would think it's not a good candidate for the cause of the two problems. There have been no problems until this month, and I've been doing weekly patches since I got the system in 2013. I was/am not in the mood to change the battery! Since I've already bought the new one and have no other use for it, and since the old one is 4+ years old, I plan to change the battery either Friday or Saturday. But you know what they say: "If you want to make God laugh, tell Him your plans!". I did watch the youtube that Tim provided. I don't recall seeing screws on the underside of the motherboard. I'll look again Friday or Saturday (God willing!). Thanks, Bill. _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org
