#1 Phillips Screwdriver is about all you need as far as tools

There is option in display properties (can't remember the exact tab at the moment) that allows you to use a web link associated with your background, uncheck that and the issue should resolve (I think the url link associated is now invalid)

try the lcd inverter chip. it is commonly 90% of the time the problem.

I think you may be referring to the green power light and the orange hard drive activity light.you should have a power icon located on the bottom bar on the desktop near the clock that indicates battery power.

how did you check the inverter is okay because unless you have a $5000 machine its pretty tricky "or the same laptop"

dark screen. inverter is bad
nothing to do with the board.

the lcd screen may be causing this. Try to connect the laptop to an external monitor and have both working at the same time by toggling Fn F8 on the keyboard. Wait until it goes black on the LCD. post back what happens. If the external monitor wont go out when the lcd does, the lcd may have to be replaced. If the monitor goes out too, it's a video card issue which may be resolved by reinstalling the driver.

That sounds like you have something loose ..

Here is an on-line service manual for that

I would look specifically @ the LCD/monitor lead and its connections

Try holding the "fn" key and up-down arrow to lighten or darken it.

Check first by connecting it to an external monitor. If you see that it is the same problem in the external monitor then I think there is something wrong with your video card. See if you can re seat the video card.

This issues also come from the cable that connects the LCD with the motherboard. Have you opened the Laptop anytime and moved the cable?

Check these first. It sounds something loose or a something related to video card.

check your power cord and make sure it's plugged in all the way, and if it is, check your brightness setting.

Usually it's the Fn key + an arrow key. Make sure the brightness is up all the way
