I hold a Sony Vaio VGN-FS550 an the monitor flickers from really bright to weak. Any thinking??
Answer:
If the computer switches from bright to smaller number bright when the mains power/charger is disconnected after that is a conventional power saving piece.
If the mains are still plugged surrounded by when you do this, you could have a loose nouns in the charger or within the cable that connects the screen to the laptops motherboard, or a loose nouns in within the monitor itself. If the monitor is really dark that you can see almost nil there might be a problem near the screens put a bet on light.
If it really bothers you contact a reliable PC technician.
You own one of two problems: Either your video card is bad, or, more probable, the monitor cable is bad. Sometimes the ribbon that connects the blind to the laptop base can come loose or catch pinched. You'll need a professional to look at it. It's really assured to take a laptop apart, but incredibly hard to take it back together.
