Hello. My Toshiba laptop stopped working. When I press power button, it lights up, battery indicator and power too. But display is off, no BIOS. I've tried battery tricks, connecting trought VGA/HDMI to external monitor, but no signal, resetted BIOS by CMOS battery, putting in and out RAM stick, checked other disks, but still nothing. Only fan spinning. No leds on numlock and capslock.
|Sorry for my english :( |

It may actually be working and just the display isn't. 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.
