Toshiba laptop won't boot.

[xxxvegexxx]

My laptop won't boot: lights are on, the fan is spinning but the screen is always black.
I've tried both removing the power and pressing the power button for 1 min and replacing the CMOS battery with a new one. Is there something else I can try or is the mobo gone?

Did you remove the battery?

Yes.

If you're handy, try checking the memory modules. If it has more than two, try removing one and see if it boots.

I removed both memory modules and I've put them back and the laptop still didn't work. Then I've removed one and left the other in but still nothing...

Hi, did you try an external monitor?

The display ain't the problem: on my laptop there's a little red light that turns on when the bios has booted and this light doesn't turn on anymore.

Remove the battery and try to boot again.

Battery has been removed since the laptop stopped working so all the booting attempts were done without the battery.

Ok, what LED does not light, is it the LED for the WLAN?

Exactly, the WLAN LED ain't lighting.
The symbol under the LED is this one: http://us.123rf.com/400wm/400/400/medusa81/medusa811205/medusa81120500047/13830065-wireless-wlan-icon.jpg

It seems that something on the motherboard is defective, the laptop won't event POST. The last thing you could do is to disassemble the laptop, with just the motherboard with the adapter and plug to an external monitor, try to boot, if you have nothing on the monitor, then some component is defective.

The last thing that appeared on the monitor before it stopped working were some codes regarding HDD. It said that it wasn't able to recognize the HDD or something...

You can remove the HDD to see if it will POST, but I doubt the HDD stop the laptop from booting.

I've removed the HDD and turned the pc on but I still got the black screen. I've also inserted another HDD that I had from another broken laptop but still nothing. I guess the HDD ain't the problem.

No, try to go in the BIOS.

No, try to go in the BIOS.

And how do I do that from a black screen?

 

[jarotech]

If you can go to the BIOS, the screen will not be black. The BIOS is somehow before and part of the POST or vice versa.

I get it but how can I access the BIOS if when I power the laptop the screen stays black as nothing happened? Are there any key I should press?

 

[jarotech]

When you push the power, right after push F2 rapidly, but I'm sure it will not work, nothing to loose.

Do you think that the mobo failed and if yes how much would a new mobo for this laptop cost?

Yes, something on the motherboard is defective, you will paid between US$75 and US$150 for the motherboard depending where it come from, without the cost of the shipping.
