Hi,

This computer only shows the power light on the button (white) The fan and hard disk are spinning. No Beep tones. I saw a post about the BIST test. I tried that and the screen lights up with different colors. Mother board problem? Is there something else I can try?

Thanks

You can try replacing the RAM (memory). If there are two memory modules take out one and try to start the laptop with just one module. Try another module if this does not help.
Other things that may prevent the laptop from booting is hard drive (rarely happens) and may be the LCD screen is faulty. But as you said the BIST shows different colors so the LCD should work.
