If the humming noise is coming from the base of the screen, then it's the inverter and it will need replaced. You can check to see if this is a screen related problem by connecting an external monitor, if everything functions correctly on the external, then it's in the screen area. If you still have a black screen on the external, then the problem is internal, and the humming would indicate a serious problem that may need some professional attention. Try the external and let me know. If it's something other than the screen area, we can try a few other things in order to track down the problem.

Have you tried an external monitor to see if the screen is faulty?
The fact that the DELL screen comes on shows that the bios is running. Try pressing F2 to get into the bios and reset to defaults.

I took my toshiba sat. 1415 apart. i have two wires, 1 black, 1 white with little round ends. they go from top half threw a hole to the bottom half at the top right corner. what does these wires connect...

They connect to the wireless card. If you flip the laptop on its back so the bottom is up and the front of the laptop is towards you, the wireless card access door is to the back of the laptop on the left side. It has a single screw holding the door in place. The little sockets on the card should have a small black and a small white triangle by each socket. That is where you clip the wires to. I believe the white cable connects to the left and black to the right. Below is an illustration of the card in the slot with the wires connected.

My laptop, an Acer Aspire 5715z, has a big ol' white patch on it with a smaller one at the top of the white one. It covers about half of the screen, and it has blue around the start of the white line.

Oh okay. Your screen is physically cracked. Its broken, its going to need to be replaced. Thats why a part of the screen is coming and then you see splotches on the screen. Looks like somebody hit directly with something or stepped on it. If you turn the laptop off and shine a light on it, you might be able to see where the crack originated.

In the meantime until you get another lcd screen, you can hook up an external monitor to the laptop and use it like that for now.

Acer Aspire 9810 Screen Problem

Hi No otto,
On the bottom row of keys, you will see one marked Fn, in a different color. Hodl that and look at your top row of keys. Should be one with a laptop screen, and a monitor. The little graphics will be the same color as the Fn key. Tap that once, wait, see if the screen comes to life. Usually that key is set to choose "Just laptop screen, just external monitor, or both", with each tap.
Good luck,
