My mom has an old laptop, an ASUS F5SL bought in 2008. Although the battery is dead for a long time all other components used to function perfectly to this day. I just made a fresh install of Mint 18 XFCE to keep the 4.4 kernel series (Mint 19 wouldn't recognize the atheros wi-fi card no matter what I did, ath5k just wasn't there even when I installed the kernel headers and extras and there wasn't any other instruction to get it other than compiling and installing a vanilla kernel), and upgraded to 18.3 while keeping the kernel at 4.4.131. Now, I'm experiencing these problems and I don't even know which one to attack and how anymore given the computer's "quantum" state of things sometimes working, sometimes not, so I'll throw a list:
- The computer "sometimes" does not boot, and I'm suspecting whatever is wrong happens before GRUB. Sometimes, after the BIOS splash, there is just a cursor blinking and nothing happens. Other times, grub shows up, LM splash screen comes up and computer boots perfectly.
- The computer "sometimes" cannot suspend. I realize that the most common reason is the swap being too small, but the computer has 2 GB ram and 4.1 GB swap, so that's not an issue. Other than that, I have no idea.
When I say cannot suspend, the screen goes black but is not turned off and the computer just keeps on running indefinitely. Magic REISUB does not work in this case (even if there's no kernel panic), the computer does not come back from suspend and the only way to get out is turning off the computer. This happens randomly, all suspending methods including inactivity, closing the lid and calling pm-suspend sometimes work and sometimes fail.
- The computer randomly turns off "sometimes", just while surfing the web using Firefox and doing nothing fancy.
- The computer "sometimes" cannot shut down, most cases experiencing a kernel panic while others just freeze like the cannot suspend case. Other times, the computer just shuts down, and it does it fine and real quick.
memtest returns fine and the SMART of the HDD is fine except high airflow temperature (turkish).
I'd appreciate any comments on where to start. I checked a lot of logs but when I searched for the stuff I found interesting over the net, I didn't have any meaningful hit backs from search engines. Just name it and I'll post the log here.
Thanks for your time,
