G3 B&W Will Not Start Up

Nothing at all happens when trying to start it from either the front switch or the keyboard.

I mistakenly disconnected the power to my Blue & White G3 early in its start up sequence. It made a noise (clunk) that I had never heard before, seemingly coming from the area behind the front manual startup button.

Now, the computer will not start up at all. Nothing at all happens when trying to start it from either the front switch or the keyboard. I have swapped in a fresh battery; checked the seating of boards, cards and cable connections; etc.

Any idea what broke? [Does the front-mounted switch mechanism contain startup/timing relays that likely broke?] Can I fix (replace) the broken part myself, e.g., get the part of E-bay or otherwise? Or, must it go into a shop?

Thank you.

I would try to press the "Cuda-switch" for a few seconds. You will find this on the motherboard. As far as I remember it is a little push-button about 1/4 inch across. I guess you will find more if you performa a google-search on "Cuda Switch" e.g http://resale.headgap.com/osxnotesbw.html

Thank you for bringing the CUDA switch to my attention. The computer is now fully functional again.

Resetting the CUDA switch on the mother board fully restored the computer.
