I'm in trouble, ArchLabs and Manjaro freeze while loading

Technical Issues & Assistance
#1




My laptop froze in screensaver so I had to force reboot it, now I can’t boot into AL at all.
I restored a timeshift backup from a few days ago, nothing, chrooted into it and upgraded…Same problem with the Manjaro install, I can only boot into it with the fallback image that has kernel 5.7 but it takes a few minutes to boot, and this is on a SSD.
With ArchLabs I managed TWICE to get to the login screen/lightdm but after entering user and pass it freezes, no kbd no mouse after.
The big problem is that booting from a live USB it’s also very slow. I even deleted the esp partition, rebuild grub, updated the fstab with the new esp partition, commented out other partitions in fstab…
I am a bit lost here, I’m still a Linux noob that started using it a few months ago.

First thing you do is backup all your data and important info.
Second thing to do is test your HDD for errors. It maybe failing. :scream:

Yep, happened to me a little while back & as usual I didn t have any backups done.

Edit, had new ssd on hand, saved some time on reinstall.

#4

This is happening on a new SSD that I bought a few months ago. I do have a HDD present in the laptop but the esp and linux partitions are all on the SSD only.

#5

Backup your important data first, then fsck and gsmartcontrol may be helpful.

Is possibly a hardware issue rather than a software issue?

Try another OS like Ubuntu or something similar and see if it persists.

#7

Hey is your RAM going bad?

I always thought the problem is with the HDD so I bought a new SSD about 3-4months back and since then I had no other problems(I use the hdd only as storage now). Before I got the new SSD I did an overnight check on the RAM and there were no errors.

Booting from the live USB takes more than 5 minutes but for example today it froze 3-4 times in the booting menu after I pressed F12. I don’t know what the hell is wrong with this system, the laptop is almost 5 years old, thinking to get a new one but I’m still pissed because it was working just fine for me with the new SSD and 8GB of RAM it was enough for my needs.

#9

Is the CPU overclocked?

#10

Nope, except from the new added SSD everything is standard.

#11

Oh, wonder if the ssd s good or was defective.

#12

PROBLEM SOLVED!
So after trying different things without success my next step was to try a BIOS update, remove the HDD, retest SSD and RAM.

I think I swore for 10 minutes continuously :rofl: I wanted to do the BIOS update but the power test was failing and after inspection I realize that the battery was not working at all because was wrongly forced into its slot so I set it in correctly and did the BIOS update, now in 7-10 seconds I’m at the login screen. I can’t be 100% sure if the BIOS update or fixing the battery did the trick, but that doesn’t matter much right now. Everything back to normal! yayyy(paru) :smiley:

Thank you, imagine how glad I am :slight_smile: I was seriously thinking on spending some money on a new laptop or desktop, now I can waste those money on food and drinks :laughing:

So I learned that BIOS UPDATES can be VERY important sometimes, that’s something to remember.
