A questão
O leitor de superusuário waivek quer saber como impedir que dispositivos eletrônicos próximos desliguem a tela do seu laptop:
About six months ago, the display on my Toshiba laptop started turning off whenever I placed my mobile phone or sound bar next to it. If I move them away, the display turns back on. How can I fix this so that I can keep other devices next to my laptop?

A resposta
O contribuidor do SuperUser Rahul2001 tem a resposta para nós:
Most laptops have something known as a Reed Switch. This is an electronic component that switches the display on or off. Your display lid has a magnet, and whenever the lid comes down, the switch detects it and switches the display off to save power. It looks like this switch is detecting the magnets in your mobile phone and sound bar speaker.
Since this issue has just started recently, it probably means that your switch has gone bad or become displaced. This can happen over time, especially if you dropped your laptop or knocked it against something. Here is what you can do:
Method 1 (Easy)
This way your laptop display will not switch off if you put the lid down, but other magnets will not turn it off either.
- Click the Start (Windows) Button
- Type Power Options and press enter
- In the left hand pane, click Choose what closing the lid does
- Under When I close the lid, select Do nothing (you can do this for battery or plugged-in modes, or both)
- Click Save Changes
Method 2 (Difficult and Potentially Expensive)
This way your laptop display will still switch off if you put the lid down.
- Open your laptop up or take it to a repair shop. Have them take out the reed switch or replace it with a less sensitive one
- If your laptop has multiple switches, you can take the one nearest the space bar out
Method 3 (For Hardcore DIY Enthusiasts and PC Building Geeks)
Do this if the issue persists even after replacing the switch. This way your laptop display will still switch off if you put the lid down, but your mobile phone will not trigger it.
- Open your laptop up
- Use wires to extend the connections and place the reed switch elsewhere
- Open the lid up and place the magnet correspondingly
