Have you tested here CD/DVD drive with a bootable disc. If the optical drive doesn’t work in Windows, it doesn’t mean the drive is bad. Try booting the laptop from a bootable CD (Windows installation CD, live Linux CD, etc…) If the laptop boots but cannot read the same CD in Windows, this is software related problem.

i said try portable dvd rather than replace it, then i found all 3 usb ports dead and speaker

Again, this could be software problem. If you can start the laptop from a bootable CD, try booting it from Ubuntu disc.
After it boots Ubuntu, test USB ports and sound again.

i need board schematic, i want to try repair it before replace the board. or any suggestion ???

Sometimes, turning the computer off, pressing the power button for 10 seconds, and turning the computer on fixes the problem as the mobo might be heated up, it worked before with me.

It might help if your laptop stopped turning on completely, but it will not help to fix failed USB ports.
