Qosmio X505-Q870 black screen? Or unpowered screen.

Hi all. I have a Qosmio X505 that seems to have somehow... died. I can turn it on or off, yet the screen never seems to get powered. Or perhaps its never getting a video signal. Either way, the screen never comes on. I don't know if this is related, but a couple days after the screen died, the keyboard backlight also stopped working. As stated I can turn the thing on, but it never does anything. It never throws an audible code, the screen never comes on, and the sounds that its making never change pitch. Often times you can tell something is wrong with a device when the sounds its making just stay the same and never change. Not very scientific I know, but maybe its some kind of indicator. Who knows.

Anyway, has anyone here ever experienced this problem? I took out the RAM, the hard drive, and the battery. The computer acts as though it can't even tell there has been any change lol. So what should I do? I've read a little here and there on these notebooks, and it seems that they have a habit of the motherboard dying. Or would this be more along the lines of the GPU?

 

Update: I did a little testing.

The fan does indeed come on when you turn the computer on. When I plug in the charger and turn it on, I have 3 of 5 lights. The three lights that come on, are power, battery, and charging. The other two do not. They are the hard drive light, and the one that looks like a piece of paper with the top right corner folded. I do not know what that one is.

When I hooked up the HDMI output on the laptop to my monitor on the gaming rig, the monitor simply says "No signal".

 

It is odd that only 3 of the 5 lights are responding; which would indicate the hard drive is having issues [note: the icon of the "piece of paper" is the "page file usage" indicator]. If you have a spare laptop harddrive laying around, you may want to try hooking it up to your Qosmio and see if that works.

However, I am not an expert when it comes to these types of issues; hopefully someone more knowledgeable can chime in.

Good luck

 

Well I put the hard drive from the broken Qosimo, into my dad's Acer. And it seems to work perfectly. So unfortunately for me, its not a hard drive issue. I'm guessing the motherboard is dead. Is there anywhere that sells refurbished laptop motherboards?

 

Or is there a well known place in the US that I can send the motherboard to, for refurbishment?

 

Take a chance here?;

Or search ebay, you should be able to find a replacement board there.
Often when a laptop model line is closed out, the unsold systems get stripped and sold as parts by the people who have them. ebay is usually loaded with such hardware.

Sending it out to a total stranger can be a big gamble.
