If it’s a remotely controlled dimmer, it’s likely that RF interference from the switching power supply is causing the issue. You may need an AC mains RF filter, AKA a noise filter, and possibly an RF choke (ferrite core filter) for the line cord, cord to the laptop, or both.
How do you stop a light switch from controlling an outlet?
The easiest way to do this is to disconnect the red and black wire from the switch and wire nut them together. Use a blank cover to cover the switch box. This allows you to go back to switched outlets in the future if you want. Make sure there will still be a light controlled by a switch by the door.
Should I be worried if I see a very brief orange spark when I plug something into an electrical outlet?
On the other hand, repeated instances of yellow or orange sparks – for instance, seeing them every time you insert or remove a plug — are a warning sign. These sparks are indicators of danger: faulty or loose wiring, an old outlet, or any kind of electrical damage can lead to these brighter sparks.
Why do my lights turn off when I plug something in?
Probably a broken wire or bad connection in the box behind the outlet where you plugged in. I recommend getting an electrician to look at it RIGHT NOW. You could cause a fire in the wall and burn your house down.

What does an orange spark mean?
Orange sparks are like slow sparks that miss fire and creates other problems, so blue is more effective and that’s how ignitions are designed to properly be efficient. Orange sparks could mean ignition problem in the coil, a bad ground or too much resistance.
Should plug sockets spark?
Harmless sparks- When an appliance is plugged in to the mains, or turned on, electricity is transferred from the circuit, into the appliance. This can be a rapid process, and can sometimes result in a small, brief spark of static electricity. This is not something to worry about in most cases.

Can a bad electrical outlet affect others?
When they say that a bad outlet can cause the other outlets to not work, that usually refers to the normal outlet that you use every day to plug in your devices. However, the reason the other outlets aren’t working may actually be linked to another type of outlet — a GFCI outlet.
How often should electrical outlets be replaced?
Outlet and wire degradation – Outlets and the wires behind them can age in as little as five years. This can make them quite susceptible to harm. Over time, wires can settle, and this changes the way they make contact. If the changes are just right, they can cause sparking, arcing and fires.
How do you know if you have a bad GFCI?
Push Reset Button
If the GFCI won’t reset or the button doesn’t pop out when you press the “test” button, there may be no power to the GFCI or you may have a bad GFCI. Pro tip: If the “reset” button trips again every time you press it, there may be a dangerous current leak somewhere on the circuit.
Do outlets go bad?
Just like everything else, electrical outlets have an expiration date. They will perform their function for a while but eventually a time will come when they get worn out. A worn-out electrical outlet will either stop working completely or it will give you lots of problems.
What does it mean when an outlet sparks when plugging something in?
Normal sparking
Sometimes outlets flicker when you plug in an appliance because you are diverting fast-moving electrical current into it. This causes a quick draw on the available power, which results in a brief flash. This is likely normal unless it happens on a consistent basis.
Can an outlet catch fire with nothing plugged in?
An outlet can also catch fire even if nothing is plugged in. This can occur in homes that use aluminum wiring. If your house was built more than 50 years ago, chances are, it was built with aluminum wiring. Aluminum wires are more likely to catch fire, because aluminum is softer and expands more than copper.
Can an outlet cause a fire?
It can happen due to loose or corroded wires, wetness, or unplugging something from an overloaded outlet, and may even result in a fire. If the outlets are wired correctly, have been tightly secured, and stand in perfect condition, the chances of it catching fire are bleak.
Is it normal to see a spark when you unplug something?
Normal Spark
Electricity runs along circuits and back to the main grid without interruption. When a device is plugged into the outlet, some of the electricity transfers from the outlet to the device. When you unplug it, you’re breaking the electric contact, causing the spark.
Why is there a blue spark when I unplug something?
Just before a plug touches an outlet, when the two are very close to each other, an electrical current from the circuit will reach across the tiny gap and create a spark. This small, blue spark is normal.
What causes electrical sparks?
An electric spark is an abrupt electrical discharge that occurs when a sufficiently high electric field creates an ionized, electrically conductive channel through a normally-insulating medium, often air or other gases or gas mixtures.
