Re: Laptop no longer booting...
At first glance, I think your laptop is dying.
I carry an Ubuntu install on a USB stick for rescuing PCs, and based on what you wrote you appear to have tried the right things if the issue was only software/OS based.
To retrieve your data, you may have to remove the Hard Drive and use on of those SATA-to-USB gizmos. I have one (SATA/IDE to USB) I only use once in a great while, but it save been a life saver (data saver?) for those folks that needed the help.
I think the issue is NOT your hard drive, or the USB/CD boot would have worked, so there is a good chance you can save the data on the drive.
Look at all those flashing lights! I'll take one!
