Is there any way to tell what in this PowerBook 5300 has failed? I'm getting
only the 3 chimes after the initial boot "gong".

It would be nice to be able to do some troubleshooting, by process of
elimination, but I need to know what the power-on test is looking for.

Will the test pass successfully without a RAM card? A hard drive? Keyboard?

Trackpad?

I could, module-by-module, reduce the PB to just a power supply and mother

board if I knew that the power-on test wasn't expecting all of these modules.

I've checked the Apple Support archives and can't find any information about

the power-on test.

Any clues?

Do you ever see the happy computer icon?

For starts, have you attempted to startup using a floppy disc having the
system? Inserting the floppy before starting the boot will force the computer
to attempt a floppy start. I recommend for test, any of System 6.04 through
7.5.

I'm sure the startup includes a test of the RAM. At boot, the computer puts
the System into RAM.

I know a defective keyboard can, but not always, prevent booting. I had to
replace the "bronze" keyboard (only $64) when I was unable to clean out all the
Latte'.

If it would help, I could dust off the 5300 and pull the kbd to see what
happens.

Let me know.
