Question about Toshiba Satellite (K000004080) Motherboard
My daughter's laptop won't turn on. The power button glows red, along the front of the laptop on the left side the power cord light is blue and the power light is red. The screen is black and there is no response when I push the power button. This computer is only 14 months old and this is the second time this has happened. The first time it was fixed under warranty which has now expired. I read that the fan could be dirty or the motherboard could need replacing. I'm no computer tech but would be willing to try to fix it myself since, with no warranty, what do I have to lose? Any suggestions you have would be greatly appreciated.
Open the back panels, blow out EVERYTHING and remove and re-insert everything. You could just have dirty contacts somewhere. The dust from the fans also travels around inside the computer.

Tips for a great answer:
A blacked-out screen doesn't necessarily indicate a broken monitor.
If the computer has run out of charge or is in hibernation or sleep mode,
if the screen is too dark, or if the display cable has come disconnected from the motherboard, the screen may appear black or fail to turn on.
To fix a blacked-out laptop screen, troubleshoot the screen settings, check the LCD connector and see if the computer is awake and receiving power.
Touch the touchpad or move the external mouse to see if the computer is asleep or hibernating. If the computer fails to respond, press "Enter" on the keyboard.
Press the power button if the screen remains black.
Confirm that the power indicator light, found at the front of the computer or above the keyboard, is glowing solid green or blue.
Confirm that the power adapter is plugged into the computer and into a wall outlet. Confirm that battery indicator light is glowing solid green or blue.
Hold down the "Fn" key. Press the up-arrow to see if the screen brightness increases.
Some computers also use the "F6" or "F7" keys to increase screen brightness.
Hold down the power button for 10 seconds to turn off the laptop.
Remove the AC adapter from the computer, close the screen, and then turn the PC over.
Slide the battery latch to eject the battery. Pull the battery out of its compartment.
Turn the computer back over, open the lid, and insert the edge of a flathead screwdriver or other flat, solid object beneath the bezel above the keyboard.
Wedge the edge of the keyboard bezel off of the top cover.
Work your way along the edge of the keyboard bezel to loosen it.
Pull the bezel off the laptop.
Trace the cable coming from the laptop screen to the connector found beneath the bezel. Reconnect the display cable to the motherboard if the cable has come loose from the connector.
Line up the tabs on the bezel with the slots along the top of the keyboard. Insert the right edge of the bezel into the gap above the keyboard, and then push the bezel back in place.
Turn the computer back on. If the laptop screen is still blacked out, connect an external monitor to the video port on the side of the PC to confirm that the video card isn't defective.
If the external monitor works, the LCD screen could be broken.
If the monitor doesn't work, the motherboard or video card might need to be replaced.
Hope this helps
