Well the Flashing "lock with 9" is Num Lock, the "blue lock with an A" is Caps Lock, and the "blue lock with a down arrow" is Scroll Lock. Hope that answers that question.
Now for the screen being blank usually means there is an issue with either your LCD display or an issue with the laptops video card. Plug in an external monitor and boot up the laptop if you still get a blank screen then there is an issue with the laptop's video card. If you can see your screen on the external monitor then there is an issue with the connection of the LCD displayon your laptop. You can try ifxing it your sleve by opening up the laptop and making sure the connection is firm or you can take it somewhere to get it fixed.
Your Back light has most likely gone out.. There is a possibility that your resolution may be to high or that you have it set to output on an external display... If its your res. you should be able to hit F8 at startup to enter safe mode... If it is the external display you need to hit FN + the key that has a little blue or yellow monitor (its a different key on each laptop)
If you are hooked up the the external monitor and/or TV and can see the desktop, you can probably reselect the internal display via software from Display Properties.
In most cases you can change from the external display to the internal and vice versa by holding down the blue Fn key, and hitting the proper number on the keyboard. The correct key has a blue icon meant to resemble a monitor on it.
This is if the repair/replacment of the internal screen was done correctly and the screen is actually working. If the screen is not actually working, though, this will not help you.
your external screen needs replacing...you would have to take it to an authorised repair person to replace it because it's very tricky to change.
