So, a few days ago I got the 'Repairing disk errors. This might take over an hour to complete' message. For a couple of hours, it hadn't gone away from that message so someone decided to turn it off.

I believe this may have been a bad decision because now it will not turn on.

Here's what I've found so far:
1.The power button lights up.
2.The CD Drive spins discs
3.The fan turns on.
4. Screen is absolutely black like it's still off.
5. The Hard drive seems to only spin half way and the head doesn't not move.

It's Toshiba Satellite C55D-B5310. I've been searching everywhere but if I missed an answer to this question I would appreciate it if someone could direct me to that.

Thanks.
 
It sounds like it is actually on, but the display isn't. Sounds inside and the CD drive moving means it is on and getting power.

Try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.
