Hi guys, I'm new and this is my first post, I don't know if there's necessity of a bit of presentation.
If not, well, I'm going to describe my problem:

I've this IBM Aptiva 2144-743 and I've decided to switch on it (the last time was soo many years ago) , but when I've clicked the button , the fan started up but It switch off immediately.
Soo thinking that was the power maybe? Then I've tryed to switch the red lever in the back of the pc, from 230V to 115V and........I messed up , there was a bang and some smoke comes out from the PSU fan.

I've tried to open it but I don't know how to do this

Can you give me some help, starting from open it? This is my first approach on a very old and magnificent machine, but I know nothing, really 🤣ù

I'm truly grateful, have a nice day !

Yeah I know, infact I don't want to open the Psu but The pc itself, I've searched for a video tutorial but I've found only a guy that "slide down" the cover, maybe there are some lives that I don't see?

page 4-2 or 128 of the pdf.

But you've 100% killed the power supply so your not going to be able to do much.

Your obviously learning (as flicking that switch will even kill new PSU's) and nothing wrong with that we all had to start somewhere but post pics of the power supply connecters here before doing anything else.
The good news is the PSU probably sacrificed itself and saved rest of the PC.

The standard AT power supply cable to the motherboard was in 2 parts. You always connect "black to black"

IBM's aren't necessarily standard though, Post here may help if it isn't a generic PSU but you would want to double check if its applicable to a 2144-743 as I'm not sure
