I was using my laptop when the screen went blank, and then the battery went dead so I put it on charge and pressed the power button. The LED for the power button came on but nothing was happening, no sound from the laptop or anything, except for when you put a disc in the disc drive then the drive makes a sound like it is reading the disc. I have tried several things such as leaving it off for over one hour and leaving it on for over one hour. I even tried connecting it to a monitor in case the screen had broke but that didn't work. The screen remains completely blank as if the laptop hadn't even been turned on. I need it sorted out quick as I have lots of coursework to do and I don't want to have to format the hard drive either.

the white dash is a command cue and it is waiting for you to enter a command for the laptop to proceed
when you switch the laptop on , hold down the delete key until the bios screen appears

Look for the function (FN Key) combination. Most laptops have a power saver mode wherein you can power on and off the monitor only. This is done by using a FN key combination. It is usually FN+F1 or F2 for most laptops. Look through the keyboard, the sign for it is usually an icon of a monitor with some sort of X or line accross it. Press and hold down the FN key plus the key with that icon and it should bring up the display.

Were you working with laptop in battery mode, not plugged in a/c power? You could have drained your internal DC battery & at the same time damaged your B.I.O.S. [button type] battery inside the laptop. that the computer goes into POST means that it is trying to FIND itself, not finding the graphics card, it does not know what type of 'picture' ( usually black screen with ""DOS"" words ) to show you. 1st- turn laptop on, you should see name,what type of cpu (the "inner " workings of computer) and sometimes the amount of memory (clicking like a digital timer) If not, don't worry. Press f1,or DELETE, ESCAPE (ESC), or read your book to find the KEY to puts you into SETUP. There should be a menu and somewhere there are DEFAULT. USE THOSE! Reboot to see results.
Try taking the battery out before you turn it on. Have seen completely a dead dead battery keeping a laptop from starting up. Does the hard drive activity light flickering? If it is you can try holding down the Function button (FN) and there should be another button to hit to switch between LCD\CRT.
Connect your computers to an external monitor and press the appropriate F key combination (Shift + F7) to switch video output to the monitor. If you see an image on your monitor you have a bad LCD screen or back light inverter. If not you need a new motherboard. Guy that gets ticks, you need a new motherboard anyway.
I have the same problem, and my problem was that I have installed 4GB ram and that ram modules wasn't accepted with the new bios. So I installed the old modules and it all worked again, downgraded the bios to one version older and installed my 4GB ram modules and it all worked.
