I get laptop?

timidapsin:


I bet no one ever thought of this until now.


So you have been using your laptops for years

And it is mostly plugged to an electric socket

Now people are wondering, what small cylinder?

Yes that small Cylinder

The cylinder is known as Ferrite Bead.



It isolates the laptop from the electro-magnetic noise that occurs from the waves picked up by the cable, or from the noise in AC-DC converter.

It is a kind of electronic choke


It dissipates high-frequency currents in a ferrite ceramic, and helps make the most powerful noise suppression device! It is called a core, block, or EMI ring.

So, that is what it is all about.


Do share this significant piece of knowledge with your friends. Of course, after asking them about it, and projecting yourself as the smarter one!

Ok.....seen and noted.

mine no get oo.

lofty900:
It's called surge protector.

Varistors are responsible for power surge in laptops .

Chuksemi:
The thing is I use an Acer506 double egded sound laptop. Comes with an in built electronic charger and bystand battery.

I don't need this. As a rich hausa boy.

Who ask you ?

not on apple laptops

Na for old lapy

I know this already .

Op thanks for the info, but you need to know that most original charger don't have it, why?

OP is talking of old model charger. This kind of charger is outdated.

This is like telling us about tube when cars are now running with tubeless tyre.

I have Acer and Lenevo charges here for instance, none of them have your legendary cylinder.

Thanks for the info

timidapsin:
its not surge protector

Its called the Ferrite bead
A ferrite bead, or ferrite choke, is a simple hollow cylinder or bead that is made of ferrite material and that is used in order to suppress or filter the amount of high frequency electromagnetic interference (EMI) noise found in electronic circuits.

Can u please use d language normal people understand.. ... Please en

I supposed u got issues with ur sight right..imagine u fooling urself just because u wanted to get noticed..I weep for u bro..if I were u I will just try to commit suicide like teebillz.
Can't u see what he circled in the pix before making such comment..no harm but its just too annoying wanting to correct someone and ended up the foolish one..

franktolk:
OP ...pls that's object is not cylindrical but rectangular . You got me a little confused when you said "cylinder" until I saw the picture .

Anyway ...it's a very informative and educative write up . Thumbs up !

Were you not taught the topic 'shapes' in Maths?
Does that look like letter 'I' to you? Haba!

Will this cylinder end fuel scarcity? Guy make I no vex for you ooo..
If anybody asks me why I had to quote the entire thing ehn...........

Don't have a laptop but have seen it though,I always take it as a design.........thanks op


Besides,i can use it as a necklace,if you ask me what kinda stuff is this?,my answer will be"its a lovely BEAD made of FERRITE material

I guessed it, was wrong. Just topped up my knowledge bank.

My macbook doesn't have that

My tablet charger also has it so... .... ..

Too technical. Please break it down. Thanks all the same.

What if the person just drank alcohol ?

Will it protect him ?

Just asking..

mine doesnt have it

Thank you

lofty900:
It's called surge protector.

It's an EMI filter

My Sony Bravia cinema board has it.

joey150:
I think na older laptop charger...3 laptops around me..different makes..not one has that stuff.. Besides why do only laptops have it then..TV,fridge and the rest nko??

Nobody still make these kind chargers now

@OP : Thank you oh ..... before, one useless computer village person de tell say na "extra stabilizer" and wan charge me more money.

So what would have happened or gone wrong if these EMI noise isn't filtered out??

Because a laptop is an inductive load with sensitive components in it and the waveform that will not disrupt the performance of this kind of systems is a sine wave. Therefore if there is noise in the waveform of the AC supply charging it, it would have gone through the circuitry in the power pack which consists of capacitors which must have cleared ripples to d best of its ability and the ferrite bead now stands as another phase of removing unwanted noise in the waveform before it is finally passed to the system. Its more like a protective measure. You should give credits to we engineers for our thinking.

well its old technology either way..modern chargers are smaller and thinner now...

Thanks for the very detailed explanation. Did you always know that? Or you just found out?

ladyF:
my Chinko laptop charger no get am. Chai!!!

Itz not fair o... U bn snubn me lately

Chai it's not how it looks o. I'm so sorry.
