(SOLVED) Why Does My Laptop Keep Shocking Me?

Why does my Laptop keep shocking me?

The main reason why your laptop keeps shocking you is because of current leakage, faulty wiring or a faulty power supply.


Many of us have been electrocuted by our laptops or have felt a stinging feeling generated by little jolts of electricity rushing through our bodies.

This usually happens while your laptop is connected and has a metal backplate. Grabbing the top of your chargers may potentially cause you to get shocked. If you run into this bracket, there may be a simple solution to your dilemma.

In layman’s words, you’re seeing a little electrical burst from the power source that travels up the cabling and grounds through the casing.

It’s only a few microamps of electricity, and it’s not damaging or threatening. It’s simply something a switched-mode power supply does. To add to the confusion, not all adapters do this function.


Possible Causes:

  • Current Breach
  • Incorrect socket cabling
  • Faulty power supply


Current Breach

This occurs when the current flees from its designated route or surpasses the boundary defined by an insulator. In other terms, an unprotected cable in your laptop could be contacting the casing, causing you to get electrocuted.

Your laptop must have a metallic shell, and the adapters must be uncovered, as explained in the next section.


Incorrect socket cabling

In certain circumstances, the outlet you connect into is not correctly wired regarding anchoring or earthing.

Your sockets typically have 3 functions: the one on the right is the active one, from which electric current flows through anything you connect to and then escapes via the opening on the left (neutral).

The top/bottom opening is linked to the ground. It serves as a balancing, producing an alternate exit that, in this example, removes the current from the metallic exterior of your machine.

To test, insert a tester into the correct hole and it should glow. If you put it in the left opening or the upper one, and it glows, there is an issue with that connection.


Faulty power supply

One of the possible causes of an electric shock from your Laptop might be the charging adapter.

There could be uncovered padding, or you’ve been utilizing it for a long time, and that’s its way of reminding you to replace it.




How do I stop my Laptop from shocking me?

To stop your laptop from shocking you, get a three-pin battery charger or replaceits battery.


Possible Solutions:

  • Get a three-prong battery charger
  • Disconnect your laptop before actually attaching any accessories
  • Get another battery


Get a three-prong battery charger

Like your outlet, certain AC adaptors are connected to the ground, which is why the docking connector is there. This adds an extra degree of security by removing any stray current that might shock you or cause harm.


Disconnect your laptop before actually attaching any accessories

This is more of a precaution than a repair. However, if you wish to connect something to your Laptop while connected in, attempt to disconnect it first.


Get another battery

Getting a new battery is yet another simple technique to eliminate electrocution from your Laptop.A damaged battery might create an issue in your Laptop’s wiring, perhaps resulting in an electrical discharge when you contact the metal component of the case.


Why do I feel an electric shock when I touch my computer?

The reason you feel an electric shock when you touch your computer may be because there is a persistent leakage in your system or its power supply is a cause of concern.


Over a few of us have been stunned by our Laptop or have experienced a tingling feeling produced by little jots of electricity flowing through our bodies.

This generally occurs when the Laptop is connected in. You then discovered that every metal surface, such as fasteners, terminals, or even touching a plugged-in steel casing usb drive, shocked you.


When you contact the base of your charger, you may get shocked.


You could even see your screen flickering on and off for a few seconds. Because some of us sit our computers on our laps, it raises a lot of anxiety if your computer continues to shock you.


Possible Causes:

  • Current discharge
  • Adaptor not properly connected in
  • Socket wiring Error
  • Faulty power supply


Current Discharge

This current goes from its designated circuit in a hardware component to the base, or neutral, and in this example, from the Extension cable.

In other terms, electricity is flowing from your adapter to the floor, casing, or metal items in your computer due to faulty shielding or frayed wires.


Adaptor not properly connected in

This is the most common reason your computer continues to startle you. If you’ve discovered that your computer is connected but not charging, but instead shocks you, you’re in this group.

This is because just one of the connections is connected to the power source and the circuitry is not sealed. Instead, it grounds itself using the metals within your computer.


Socket wiring error

This is similar to the original one. The connection you inserted your computer into is not correctly wired according to IEEE cabling and earthing regulations.

Your plugs should usually have three slots. The middle (or right) hole, known as hot, permits electric current to flow out of the plug, whereas the first (or left) hole, known as neutral, allows electricity to flow back into the connector.

The bottom or upper hole is linked to the earth. It acts as an alternate exit, removing electricity from the metallic shell of your Laptop and safeguarding you from unintentional electrocution.

Insert a tester into these slots to see if the adapter is in excellent working order. When connected to the correct hole, the tester will light up.

If one of the other two holes lights up, the socket is bad. You might also try plugging your Laptop onto another outlet in a different unit to check if it is still in shock.


Faulty power supply

Your Laptop may be startling you due to a malfunctioning power adapter. This could be due to poor shielding or a bridging connection in the adapter.

You may have been using this adapter for a long time, which is simply a warning to purchase a new adaptor. To determine whether it is the converter, try an alternative functional adaptor (if you can find one) and see if the issue remains.

How do I stop static electricity when using my Laptop?

To stop static electricity when using your laptop, make sure you keep your power cord attached but turn the system off to keep it grounded. Avoid walking bare feet on carpeted floors till the issue is resolved.


Static electricity may be found not just on garments in everyday life, but also on laptops. Static electricity may also cause harm to laptops, potentially ruining the integral components inside the Laptop. 

These parts include the processor and motherboard’s graphical cards, since static charge can reach tens of millions or even several hundred thousand volts, breaking through into the parts.


Few simple steps to avoid laptop static electricity

Here are some useful tips for preventing static electricity from frying the insides of your computer:

  • Keep your power supply cord attached (but turn the unit off) to keep it grounded
  • Avoid pressing your bare feet on carpeted floors
  • Before touching components, touch a metal section of the chassis itself
  • Work on a firm, flat surface
  • Make use of an ESD mat
  • After you’ve used the laptop, please place it in an anti-static bag, ideally one that is dark
  • Use anti-static wristbands and attach them to your computer case

If you’re worried, don’t be; the likelihood of you destroying a part due to static charge is minimal.


Why did my laptop shock me and turn off?

The reason your laptop shocks you when it turns off is because high energy exists between the casing and the ground.


This may be in the 550 MHz and 50V range. It’s unclear why such a communication would be present in the case’s core, yet it is.

Your skin links the laptop cover to the ground and performs a circuit once your wet skin contacts the casing. The generated current is strong and sufficiently powerful that a sensitive patch of skin, such as the back of your forearm, can sense it at the site of contact.

The connections on the main cord are not interchangeable. One is linked to the ground at your local power station.

The other supplies alternating current (AC) at your conventional regional voltage, commonly 90-240V.

This indicates that one wire can offer a safe path to ground for the casing, whereas the other cannot. Depending on which direction you enter the connection, your casing will be earthed or not.


Why my Laptop gives electric shock while charging?

A possible reason your laptop gives you an electric shock while charging could be because of its faultypower adapter. It is also possible that there’s uncovered wiring somewhere around.


Users reported experiencing a little current shock or sense of voltage on their laptops while hooked into the charging dock for recharge; this occurs not just with a single company laptop but also along a broad range of machines comprising premium brands such as Apple.


Check that the power port is properly earthed

One source of electrical shock from your Laptop during use and charging occurs when the electrical port with which the Laptop is attached while recharging is not correctly earthed.


Follow the steps below to determine if the wall outlet causes the problem. You will require a power tester and a screwdriver with a lead within.

  • Insert a normal sharp object (tester) into the Bottom end of the power outlet. The tester’s indicator should be illuminated. This is typical
  • Insert a normal tester into the socket’s left opening. This isn’t normal if the led on the tester flashes even minimally
  • Insert a regular tester into the power outlet UPPER big opening. This isn’t usual if the lead on the tester flashes even a little


Why is my computer USB port giving me an electric shock?

The reason your computer USB port is giving you an electric shock could be because of a substantial leakage voltage on the machine.

Everything else attached to it will also experience a broken earth link between the IEC socket ground and the PSU’s outputs/chassis to earth the terminals.


Why is my laptop touchpad giving me electric shocks?

The reason your laptop touchpad is giving you an electric shock could be because its power adapter or charger is acting up.


Authentic Apple chargers are excellent in avoiding such a situation, while aftermarket adapters are all subpar. All switch mode power supplies can be higher or lower depending on the charger’s configuration.

There isn’t much anyone could do about it. Most switch-style power sources are created by resonance between the main and secondary coils. It all comes down to bad electrical design.



The type of electrical shock addressed here is not lethal, and it may not even be visible, causing just a tingling feeling.

In almost all circumstances, appropriate insulated wire in the outlet or charger may fix most of the issues.
