yes, there is a gas in a light bulb you energise it and it glows.
There are lights inside it so when you turn it on it glows.
when it's red, that means the sunroof stays in position when turn off the car. push it in to turn it green. when green, it closes automatically when you shut off the car.
I will take it to the dealership or call them.
You can turn it on and it will show indication of the battery percentage. You will also notice that there is light that glows up when you connect charger. There are changes in laptops over the years. If the light is blinking then wait for it to glow continuously which will mean that it is charged. If the light orange then wait it to turn green.
Try to get one more monitor just to check. If another monitor works with your computer, you have most likely problems with your video card (if you are not lucky it can be motherboard, or motherboard + video card).
disconnect your battery and then reconnect. The light should reset and turn off.
it depends on what kind of monitor
Make sure the screen isnt cracked or anything. If it isn't then just change the battery. If that doesnt work get it fixed by a professional mechanic.
Did someone turn down the brightness control?
it might be broken try to get a new one.
The Mantle is the part of the lantern that glows when lit. They are 1 inch mesh bags that get tied onto the gas line. You light the mantle without turning the gas on. Once it's burnt off, turn the gas on and light the lantern.
