ACPI errors at boot on ASUS Q500A using Mint

My grandson’s Asus shows a quick list of errors on the bios screen then lags before finally booting.

He likes this computer so much better with Linux than Windows, but the lag time when booting seems to be getting more noticeable. Is there a fix or should we change distros? If there is a need to change for better performance, what distro would be better for this laptop?
any help is appreciated. Thank you.

Well unfortunately that doesn’t show us any errors.

This is taken directly from Mint forums:
Logfiles are kept in the directory /var/log. Usually you find a bunch with the same name, with the older ones of those having a .1, .2, .3, etc., postfixed to their name so you know that isn’t the log file to look at for your current session. Probably the older ones are gzipped as well. syslog is usually a good place to start, or syslog.1 if older. Check the timestamps at the head of the file to see if it starts before or after the problems you had.

Depending on your desktop environment, there may also be a “System Log” or “Log Viewer” application installed that you can use to browse the log files.

As a beginner I’m not good using the terminal w/o a script. Does this photo help at all?

I can see the errors but it’s not easy typing the bug out lol, anyway lets get some info.
Screenshots are annoying to try an help when on mobile.

In a terminal run these 3 commands separately. They will produce text files in your home directory.

1st run this:
inxi -Fxz > inxi.txt

2nd run this:
sudo parted -l > parted.txt

3rd run this:
dmesg > dmesg.txt

What we’re doing here with the “command > file.txt” is outputting terminal output to a text file in the current directory
Once complete you can open and copy paste them in the replies, then you can delete them.

I got:
Warning:Unable to open /dev/sf0 read-write (Read-only file system). /dev/sr0
Error: /dev/sr0: unrecognized disk label

The first and third commands rendered nothing.
The second command was where I got the response. (You probably already knew that…).

Not sure what you did, but this is the expected output. granted this is a Virtual Machine I’m doing it from but it is Mint Cinnamon 20.3

I am using Cinnamon 20.2, if that makes a difference

Curious, have you resized any partitions etc on this system?

This may be the root of the problem:

I know nothing about partitions. I looked up how to find them. There is a CD drive (?) built into this computer. I am sorry I didn’t think to tell you that in the beginning.

In case you can’t read it: Partition 1… 537 MB FAT, Partition 2…750 GB Ext 4
Size 537 —530 MB Free
Device /dev/sda1
Partition Type EFI System
Contents FAT (32-bit version)–Mounted at /boot/efi


Definitely looks off, I do not see a Linux partition. I used Mint 20.3 iso, did the standard install and erase, granted my “disk” sizes are made out of only 20GB vs 750GB, you should have a 3rd one for a running machine. If you still have your bootable thumbdrive, I would suggest booting to it and running disks again and comparing. As you can see from my screens of “Disks” on my VM:

can you attatch the dmesg.txt file, it is locate in your home directory.

That is one long file! I’ve no idea how to send anything like this. I will go on Telegram and ask. If I get an answer before you get to this, I will send the file to you.
Also, I don’t have the original original thumb drive. If I need to, I will make another one.
Thanks for your patience.

Simply attach it just like you did the pictures/screen shots

dmesg.txt (76.6 KB)

Let me know if this is correct.

It worked jsut fine. i looked through it and see the ACPI error messages. Some digging resulted in certain hardware producing the ACPI error messages related to power monitoring sensor. Were you the same one whose laptop was only lasting about 40mins and could not see the percentages or approximate time remaining?

In any event I found a couple bug threads related to the AE_AML_BUFFER_LIMIT and fixes.

Again, this seems to be hardware related and I can only suggest these fixes/work arounds.
You could try a different Ubuntu based distro or attempt those fixes as suggested in the threads by blacklisting the module it loads for power monitoring and loading a different one.

I hope this is of some help.

I also noticed at the end of your demsg txt a couple things.

First your inxi output says your running Intel HD for graphics but dmesg showed a modprobe for nvidia. When you first get booted into your desktop does Cinnamon ask you to check your video drivers? My VM does, I will scan through it to see if it too is modprobing for Nvidia.

Second, I see UFW blocking a lot of internal network 192.168.1.# (each is directly followed by it’s ipv6 counterpart). Just noticed it is all.

I am wondering about the partitions. #1 is just MB, while #2 is 750 GB. Below the bar in the photo is a settings icon. I back and clicked on it and saw options to resize, delete, add, etc… Does the fact that the first one is highlighted and the second isn’t mean anything significant? Also if I save Trevor’s school files to a thumb drive and reinstall Mint or another distortion, will they work properly after the new installation? Thanks again


I meant distribution!
