My MacBook won't boot, no start chime, just the DVD spinning sound.

My MacBook won't boot, no start chime, just the DVD spinning sound.

I had to take my computer to work to be inventoried. I didn't turn it on. I brought it back home, and now it will not start. When the power button is pressed, I can hear the DVD spin, but there's no startup chime. The status light in the front is on solid, but dim. I inserted a boot disc, but it won't boot from that either—and now I can't get the disc out. Any ideas? Thanks.

"Hi! I'd first try to reset the PRAM. While connected to AC and with the power off, hold down the power button for about 10 seconds until you hear a tone and see the sleep light flicker.

Next, try reseating the RAM, and test the slots one at a time by booting with one empty, and then the other.

Is the screen black or white, and if it's white, are there any icons on it? If it's white, try booting while holding down the option key and let me know if you see the option menu."

"I don't know if this will work but try setting the SMC. Ralph

Just a thought, but something i like to try in cases like this: Remove all RAM and try to start it. If the computer starts error beeps you know that the firmware chip is alive. Start troubleshooting from there. It's all too easy to just say you'll need a new logicboard.

"The same issue happened to my MackBook Pro 2011

Fixed:

Power up, No startup sound, Solid power light, Black screen, Fan spinning, dvd drive and hard disk running,

Perform Option Command P R to reset Parameter RAM then shut down by hold on to Power Button. Then Power Up and immediately SHIFT CONTROL OPTION COMMAND Power button to reset SMC . Power down again. The put any CD into the CD drive and power up with holding the eject power. The CD make so noise and the the start up screen and boot up sound heard, The MBP17 2011 finally power up."
