Login screen goes back many times when I try to entry in Fedora

Hello,

I recently installed Fedora 40 (Lab Scientific) on a laptop with an ONKYO motherboard with an i5 M450 processor. With Fedora and any GNU/Linux that I had previously installed (Debian and Kubuntu), there was a problem with the suspend resource. The laptop turns off by itself and only it starts working again when I turn it on, it resumes working from the point where it stopped, but it does this action indefinitely. I solved this problem via GRUB by disabling suspend. After that, the installation went on normally. However, when I started it and tried to log in, I needed to insert many times password to entry finally in system. When I insert password the system seems to start process to entry in gui but go back for login screen many times.
The graphic interface is KDE and the login manager is SDDM.
The computer’s BIOS is very simples (!) and it doesn’t have config suspend item available (!!). Or it is hidden and I don’t still found it. What am I doing wrong and how can I solve this problem?

Hello,

As nobody answered my question, can somebody indicate a topic related to help me?
I go to appreciate any suggestion.

The keyboard on this 2017 laptop has a number of erratic keys that can’t be used in passwords where blind entry is needed. Have you tried using an external keyboard?

Your laptop is old enough that you need to consider replacing it. If disabling suspend
still has issues, you could be experiencing hardware faults.

Hello George,

Yes, I used a external keyboard and the problem continued! And when I finally entry in the system, I type on normally with all keys. It is strange because I already installed NetBSD and Windows 10 its and I didn’t have problems like this. With FreeBSD I really needed to use a external keyboard but without others problems. I want to give this notebook for my daughter to study. Linux has many free educations resources that Windows doesn’t have.

For most students, it is an advantage to use a system that is reasonably current and reliable. There are currently bargain prices for refurbished “enterprise” grade laptops 3–5 years old (either because a company downsized or they were using models that don’t officially support Windows 11). I worked with colleagues from developing countries where budgets for new hardware were tight, but they could often find older “unloved and unwanted” system sitting in a closet because people above them in the org chart had upgraded.

Hello George,

You are right but this laptop is what I have to give for now.
