Boot slow after battery was low

[VandiumRoadrunner]

So I was working with my laptop, and then with the battery around 8% I wrapped up my work, but did not turn off my machine. Half an hour later, no battery so I went to plug it in, and my boot was incredibly low. It took me 56s to get to the password log in. Usually the machine boots in 10-15s with the BIOS showing up for a second and then the /dev/sda1 black screen. Now the BIOS comes up the same, but for 20-30s a black screen is showing then followed by /dev/sda1 boot screen.

Could this be a log error or corruption? I ran

Code: [Select]

dmseg

as I read online that this could reviel log errors. I got the following in red error.

Code: [Select]

This was then followed by

[PCNetSpec]

talpa-vetting is something to do with sophos anti-virus on-access scanning .. have you installed this ?

Try running:

Code: [Select]

sudo touch /forcesfck

then reboot.

Once that reboot finishes, reboot again and check if booting is now speedier again.

If not, please post the output from:

Code: [Select]

systemd-analyze critical-chain

and

Code: [Select]

systemd-analyze blame

[VandiumRoadrunner]

Thanks PCNetSpec for getting back to me.

Yes, I do have sophos anti-virus running, and I think that is the problem.

I ran:

Code: [Select]

[b]sudo[/b] touch /forcesfck

and booted twice, but no avail.

Here are the code outputs, respectively as you gave them to me.

I think I see sophos eating up the most rescouces so I guess that the battery drain must have corrupted something. Is a complete uninstall and purge the best way to fix this error? I am not married to sophos, I just have it as a precaution because as a teacher I frequently get .doc and .zip files from the web. Let me know if this is the only solution or if there is another fix. Is there anything else you think that is slowing me down?

Thank you again so much.

[PCNetSpec]

Yeah I'd purge sophos .. I'd then not bother reinstalling it, microsoft office macro viruses are highly unlikely to affect a Linux host OS and office suites such as LibreOffice have macros disabled by default anyway.

.zip files are another matter, it depends what they contain .. but simply put, if you don't "run" any binary executables they contain "as root" you're safe.

Basically if you're ever doing anything with one of the zip files and their contents and are prompted for your password, DO NOT enter it.

About the ONLY reason I can think of for AV in Linux is if you want to make sure nothing you pass on to a Windows user contains a Windows virus .. and unless that was an automated process (such as you're running a mail server) I'd be more likely to scan things I got from one Windows user and planned on passing on to another using something online such as virustotal.

IMHO real time on-access AV scanners in Linux not only use system resources for no benefit, but actually make Linux LESS secure, because at the end of the day for them to work they must have elevated privileges, therefore becoming an attack surface all of their own .. but it's your system, if AV somehow makes you feel safer.....

[VandiumRoadrunner]

Thanks for the tips about office macros and  AV's. I'm a noob, and learning as I go, so AV was simply one of those regular things that I thought I need.

I purged sophos, but for a weird reason that only shaved of like 5s so I am still booting about 45s.

So running :

Code: [Select]

dmesg

and still have the two errors that I was showed earlier. I'll give more context:

Is Samba causing this problem? I am not sure.

How is this stem connected to your router ? .. wireless ?

Have you set up any kind of network mounts ?

Are you actually using btrfs ? .. if unsure, post the output from:

Code: [Select]

df -T | awk '{print $1,$2,$NF}' | grep "^/dev"

And is this a LiveUSB ?

Are you currently able to write anything to the disk .. such as creating a new file in your home folder ?

So, this is how I see the situation. When I originally installed linux, I was replacing a corrupted Windows 7 OS. When I did the partitioning or I knew I had /dev/sda1 and /dev/sda2. This is not a live usb, its on my hard drive. Granted, I do not know if I needed to have these two "files" or "partitions" (I'm sorry, 6 months and still learning the lingo). But, until Wednesday evening, I never say this /dev/sda5 Solaris Swap folder ever (I am referencing when you see the black screen right before you type in your password ones sees something like [files304203420:034230block] and the /dev/sda1 and /dev/sda2 and I have not seen this /dev/sda5 folder. I am confused as to why it is here and what it means. Does my machine detect a usb or port and try to connect to it before it goes to the hard drive and boot Peppermint properly? That is what I am thinking. Is there something in the boot menu F2 or F12 that I can do to fix the problem.

I have no idea how I got into this pickle, I just went from 8% battery to 0% battery on my laptop and then plugged up and rebooted. Sorry for the hassle.

[VandiumRoadrunner]

So I reread your questions, and I use wireless mostly. I don't "mount" anything as in a usb hotspot or anything like that.

[VandiumRoadrunner]

On Wednesday when this all happened, I updated two things: Chrome and linux-tools-virtual-hwe-16.04-edge. Could the linux tools have something to do with, and if so could I uninstall the newest versions for the one before?

[murraymint]

sda5 is your Linux swap partition. It usually gets created automatically at installation and works similarly to the "page file" in Windows. I wouldn't worry about that, it's something that's supposed to be there and shouldn't cause an extra delay.

[PCNetSpec]

Okay, can you run:

Code: [Select]

dmesg > ~/Desktop/dmesg.txt

you'll then find a file on your desktop called dmesg.txt

Can you host that online somewhere and post a link to it ?

Hello PCNetSpec

I am writing to say that I have still been looking for a solution online, and I ran across an forum blog that you also assisted on https://linuxforums.org.uk/index.php?topic=12919.15

Can you comment on if the same strategy would work for me? Thanks again.
