What is the cylinder on a charger?
It’s a ferrite core that’s used to reduce the electromagnetic interference from the cable, which acts as an ‘unintentional’ antenna, and other devices. The atoms in the core align in such a manner that they cancel the noise.
What does the cylinder on my computer mean?
On a desktop, the hard drive activity light is usually positioned on the front of the computer case. Often times the LED will be shaped like a cylinder, representing the cylindrical platters that make up the part of the hard drive that stores the data.
Why is the cylinder on my PC blinking red?
It tells you when your hard drive is being accessed, or actually an internal storage at all. If you can’t get a computer to display anything you can look at that light. If you boot it up and wait a bit. and it blinks at random intervals but constantly then you are good.
What are the 4 lights on a laptop?

- Hard drive activity light – Hard drive activity indicator. Blinking white when the laptop reads or writes data.
- Battery light – Battery power management indicator. Battery State.
What is inside ferrite bead?
Ferrite beads are one of the simplest and least expensive types of interference filters to install on preexisting electronic cabling. Inside the bead component, a coil of wire runs between layers of ferrite to form a multi-turn inductor around the high-permeability core.
What does a ferrite do?
Ferrite beads are passive electronic components that can suppress high frequency signals on a power supply line. They are normally placed around a power/ground line pair that is incoming to a particular device, such as the power cord for your laptop.
What is the function of a power supply cylinder?
These cylinders are responsible for stopping very large deviation of power over supply through the cable and power surges in currents that pass through the cable and prevent ‘choke’ within the wire to make it any further supply the current to the device.
What are these cylindrical shaped bumps in laptop chargers?
These cylindrical shaped bumps are not only found in laptop chargers but also in many other power cords, such as: mouse, keyboard, monitor cables, printer cables etc. These bumps are theoretically called as ferrite beads or ferrite chokes.

What is the blob at the end of a charger?
Most of the chargers are straight forward i.e they do not have any bulges or bumps of the wire. But there are some chargers which have a blob at the connecting end of the cord. Mostly these chargers belong to laptops, printers, and digital cameras.
