I don't know if these things use a latching relay or a triac, but it looks like the latching device driver (just a transistor) is not operating.  That would certainly account for the behaviour as switching off the mains switch would automatically unlatch the power device. 

I must admit that I don't usually switch off the PSU at the back of the PC, but it's no hardship I guess.  I doubt that there is a safety issue except that leaving the PSU on all the time would not be a good idea.

Matt,

Is this a very new computer, especially a gaming type?  The reason I ask is that I recently built a fancy desktop system for a friend that had all sorts of fancy lights on the mother-board (I wasn't expecting that!) which stayed on until I used the switch at the back - just like yours.  The computer itself certainly switched off.

Ubuntu / Re: Laptop crashed & won't boot. (solved)

I haven't a clue about partitions but as I understand it, sda1 is the main Ubuntu partition and sda2 (the one your system complained about) is an extended partition (at least on mine), although it's interesting that your system info mentions only sda1 and sda5

https://www.lifewire.com/extended-partitions-2181304 says:
An extended partition is a primary partition that subdivides into logical partitions. Operating systems have no problem managing physical and logical partitions, so you're free to subdivide an extended partition into as many logical partitions as you need to install as many different operating systems or separate virtual hard drives as you like.

I am guessing also that as your computer complained: "/dev/sda2 contains files system with errors" it must have been mounted. 

Not that all this matters as you have solved the problem.  Just saying.... ;)

I've not used fsck so looked it up when Sezo suggested it.
Everywhere I looked was a warning that one must unmount the device before using fsck - not doing so may result in corruption of the file-system. 
I'll remember that!

Ah!  It means using Terminal Commands like we used at the beginning and that you found a bit confusing - which it can be. 
If you like I'll have a think about straightforward way of doing it and come back to you.  Let me know.

Actually, it was Tony who suggested that method just now, but it's our pleasure, Goalie.   

There might be a way of making your task easier rather than changing permissions for each file individually, but if you have just a few then best carry on as you are doing as any other method would involve use of the command line. 

Cheers!

Ah, that's related simply to the permissions - if you can't write to a file, then you can't delete it either.  One can think of deleting as a kind of writing;  one is doing something to the file, and one needs the appropriate permission for that.

Hope that helps.

If you are happy with that idea in principle then yes; please do mark you first post title as [SOLVED]. 

Using "open as root" is always a good idea to try - there's nothing to lose.  We did do that earlier without success which is why we sought other solutions.  Have a go now just out of interest. 
You've been very patient and I am pleased that the problem is more or less resolved. 

May I make a suggestion about your file names?  Creating file names that contain spaces and any special characters (, ' : ; [ ] etc.), except for underscore and hyphen, will eventually lead to tears, especially when you come to manipulate them in the terminal.  Trust me: I know!  The hard way. 
For example, '3 - SECURITY CODES March 2015 to -----[334kb]'  would be acceptable as  '3-SECURITY-CODES_March-2015-to-xx'.  Numerals are fine but in this case you can find the file size easily by other methods.

Best wishes,
   Keith

JPG attachments: 100kB if you can manage it.

Q1. There were actually two questions, but I am guessing that your personal files exist only on your USB stick and that's why you want to open them there.  True?
Q2. Is there any reason why you can't move them all to your PC (where they will then become be accessible)?

We've already tried that, Goalie - I remember it well.
By the way; I had to reduce your attachment by a factor of ten. 

Would you respond to the questions in my previous post, please - you may have missed it.

OK.  We'll worry about the delete bit later. 

Since moving a file changes the permissions so you can write to it, then I don't think you have a problem because you are not going to modify files on the USB stick as it's a backup medium.  True?
Is it true that you have backup these files to your USB in order to put them into Mint 20 (or some other OS) when you upgrade?

A few questions first to help me understand.  A simple yes/no should suffice:

Q1. Are you are concerned only about the files in the folder called '2 - MINT 19.3  HOME FOLDER - Jan 18th 2021' on the USB stick?
Q2. Are those files a backup of files already on your PC?
Q3. Are all the other files on your USB stick locked as well?
Q4. You have proved that by copying a locked file from '2 - MINT 19.3  HOME FOLDER - Jan 18th 2021' to the Desktop you can open and modify the file (Read & write).  True?

I'll just have to make sure I don't delete files that aren't on the PC.

I do hope you don't mean that!  I hope you mean "I'll just have to make sure I don't delete files that are on the PC" !! Please confirm that. 
As for Root:  It matters not, but you might feel more comfortable closing the file manager and re-starting it. 

Let me know when you want to delete the USB files - just pressing "Delete" is  not enough!
