Toshiba Satellite pro S300M-EZ2401 Not getting to BIOS!

Hi,

I have a Toshiba Satellite pro laptop S300M-EZ2401. When i press the power button, the lights & fans come on, but nothing shows up on the screen. The power light (not AC power light) is flashing green-orange-orange-green-orange-orange...
(I don't know where to find the Toshiba blink codes either.)
The fan also throttles to full speed.
I don't know what happened to it.
I have tested/replaced/troubleshooted the HDD, RAM, AC Power, and primary and CMOS battery. Nothing so far has worked.

It does not get to (or show) the BIOS or make any noise.
I think it may be an issue with the GPU or screen or graphics something..

Could you Please help?



Thanks.

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.

You may also want to try hitting CTRL + SHIFT + WIN + B to try and reset your graphics driver as another possible fix.

Well, my only monitor's power supply blew last week; I'll get back to you once I try that.
