Are these instructions ok?

That's the kind of info I'd need. Step by step with pics if possible!

Or do it yourself. If you decide to do this, I recommend using a loop of 'Sellotape' firmly stuck to the flat top of the battery before removal, this is for you to hold whilst releasing the clip that secures the battery. This will help prevent the battery slipping out of your hand and landing across exposed conductors / components, which if there is any life in the battery, could otherwise damage the motherboard.

That's the alert I just got on my Dell. I have googled but to be honest, I'm not confident about fixing this. The advice 'dhg' got here from Dell seems the one to go for but how do I do that?

Not a laptop, btw. Dell Optiplex 745 should that make any difference. Ubuntu 14.04LTS with all updates installed.

I would echo Noel's comments and make just one change. I would never unplug the computer from the mains before removing the side panel and touching the frame to ground yourself. Where is that static electricity to go if you've removed the plug? Once you've done that, you can then safely remove the plug from the wall or perhaps more easily accomplished, remove the plug from the power inlet on the machine. That way, you're still holding on to the machine thus not generating any more static.
You might also want to investigate options for clearing the CMOS memory. How to do that depends on the motherboard in the machine.

Bev,
Look at this https://www.youtube.com/watch?v=MgbPT_plXC8
I'm sure you can find a dell specific manual of how to change the battery as well - usually via the dell website.
If the video shows a computer and it looks like yours watch it through and consider if you're happy changing the battery.
The battery is a cr2032 which is common. You'll need a small cross head screwdriver.
If you decide not to go ahead, it should be a relatively easy & quick job for a computer shop.
If you decide to go ahead, I would say this. Power up the computer for a while first, then whilst it is turned on, make sure you touch the metal case, this will earth you and remove any static electricity. Don't move around much or do anything that would generate static electricity until you're finished.
Now turn the computer OFF and remove the power leads. change the battery as described. If you do it quickly, you probably won't need to clear the bios, or load bios defualts, but you may need to set the bios date and time.
If you don't change it quickly enough, or the battery is completely flat, you'll at least need to press f2 to go into the bios, & set the date and time, and possibly load system defaults - but don't do the latter unless it's not working.
Selotape tip is a nice idea, but may not be necessary if the computer is flat on a surface.
Hope that helps.
There are loads of youtube videos of how to change battery on that model if you don't like this one. Good luck.

I was wearing a cotton t-shirt doing this by the way but I have just changed the CMOS battery. I am happy. The difficulty was getting the blighter out of the slot it was in. Still. :¬)

Well, I hope so. I've not had a system battery low message.

Although I do have a phantom floppy disk icon now. How do I remove it? There's no option to in any of the menus I've looked at. (Right clicking doesn't work, for example either.)

I've fixed this now, I think. *May* have been related to an Ubuntu upgrade as others have had it too. (May not of course...)
