Whenever I plug the power adapter of my laptop into the socket, my monitor (not the laptop's display), which is attached to the same power strip, briefly turns black for about a second and briefly flickers.
Is it harmful to the power adapter or the monitor?
Why is that?
Can you avoid that somehow?
Do you mean a very short flavkern or does it take a short time until it has a picture again? If it is the first, it is normal and mab can't prevent it. Otherwise I would go to the repair service with it.
I guess a short-term overvoltage or a lack of current… Try it with different plugs
(I'm not an electrical master is just an idea of mine)
As already written in the question, the monitor goes black for about a second and then shows the picture again perfectly.
Then I'm convinced that it is not defective… I always have it when I connect a new screen to the computer or with the PC using the power plug from the same. The computers probably want to tell us that everything was done correctly.
It is perfectly normal. The device switches to mains operation and parts of the electronics are briefly completely switched off.
The monitor is constantly connected to the electricity.
But not the notebook's HDMI output.
The connector strip is of poor quality, cables or plug connections are bad, cross section too small. Buy new power strip with surge protection. Filters also help with voltage drops.
"Is that harmless?" I would have expected now rather as a question. Because:
The flickering on the monitor indicates a voltage drop. Where does he come from?
Bad connection ==> narrowed cable cross-section, increased temperature development = fire hazard.
Cable cross-section too small, use a different connector strip (sometimes add the performance of the devices and pay attention to the specification of the connector strips), permanently increased material fatigue due to increased heat development ==> replace the connector strip.
Laptop power supply too cheap, doesn't really matter, as long as there's a real (and not just invented by the Far East) GS mark on it. Or VDE or CE. Otherwise, a malfunction would also be feared here. Tried another power supply?
In addition, the following should generally be avoided: hang the extension cord on the extension cord, the plug connections and the cable length are counterproductive and can lead to errors. Connect several high loads to a power strip, the supply line could not be designed for the current strength and neighboring plug contacts could heat up excessively.
Such a flickering can also come from the entrance… I would only take note of it, but nothing more. Why activate large people here when you simply plug the monitor into something else with a little common sense and then test again… Or try that with a different monitor. Everyone needs a laptop, which is best glued to the tabletop… It's not that easy to find mistakes.
