Just had to comment, there is no such thing as too many questions (assuming you actually want to learn, which you seem to)Thank you very much again, and sorry if I am making too much questions
It's a laptop, which makes me think that maybe its ground is not the plug's ground, but the batteries? Or maybe im completely wrong hahaBueno. Now, is your PC a desktop or laptop?
Wall plug doesn't have fuses your house does.By the way, at the back of the oscilloscope it says "Fuses inside" (you can see it in one of the images i posted above). Does that mean i don't have to include any fuses in the wall plug?
Thank you again

Some Euro plugs have the fuses in the plugs.Wall plug doesn't have fuses your house does.
In the 80s almost all TVs had live chassis, so some repairmen disconnected the earth lead inside the scope's mains plug - but this is *VERY* naughty and you shouldn't do it!Thanks for the answer! I didnt get it completely clear though... The yellow green wire has no end... I understand it is not 100% necessary, but advisable for security issues... Is it in this case VERY advisable?
As well, how can i know, in a normal plug socket, which one is live and which one is neutral? I'm spanish and here the plugs are simetrical...
Finally, you say i will need a fuse. Does that mean that i have to add a fuse between the plug and the oscope?
Thank you!
The local mains voltage is 220V, and the plug used here is the one with two cylindrical connectors, here a picture:Hello,
What is your local mains voltage?
What kind of plug is normaly used in your country?

It may seem a bit obvious - but I'd have a quick look inside the scope to make sure the end of the mains lead isn't all that someone's mucked about with.The local mains voltage is 220V, and the plug used here is the one with two cylindrical connectors, here a picture:
Seems like someone could have made it into a scope for field use. Pack a mini-inverter inside and run it on 12 volts DC!It may seem a bit obvious - but I'd have a quick look inside the scope to make sure the end of the mains lead isn't all that someone's mucked about with.
There should be a sound clip gallery of the sound when something unsuitable is plugged into the mains - my favourite is; "Ponk".Seems like someone could have made it into a scope for field use. Pack a mini-inverter inside and run it on 12 volts DC!
Too late for this comment though, he already said it fires up on mains power.
I have a big, heavy 32" Philips CRT Television in my basement that makes a similar noise when I turn it on. A big Gjoink - when powered up. It startles everyone in the room every time it happens. I thought it would crap out in the first week I had it but it has managed to startle people for nearly 15 years!There should be a sound clip gallery of the sound when something unsuitable is plugged into the mains - my favourite is; "Ponk".
