After searching around.. I find that the symptoms might point towards a logic board failure, however I am still not convinced that's the problem..
I hope to get at least 2 more years use out of this system.. I no longer use it for graphic or video intensive operations..
the problem:
Current problem.. / related to previous issues, I think
OS X Leopard - current update
system will freeze - mouse & keyboard input will not respond.. (infrequent)
before permission fix w- onyx & disk utility, but after OS update
- system would boot fine, however would not go into sleep mode
Previous problems
OS X Tiger
One day, this computer decided to freak out on me.
- Keyboard & Mouse would work/respond long enough to type in the login password, after initial load up.. no response from keyboard/mouse
- upon hard reset, things would function well for awhile then freeze up and either a) repeat the above issue, or b) go into kernel panic screen
- Sometimes I would get the "no hard-drive" symbol, system would not boot
- Rarely, system would lock up and fans would rev up fast & loud
- system would not go into or wake from sleep mode.
Steps I took to solve/diagnose this issuee:
- switching USB input ports
- Removing / replacing RAM
- Replacing main HD
- Upgrading OS from Tiger to Leopard
- Running Onyx & disk utility to repair permissions.
- Ran Hardware diagnostic CD/DVD - Nothing wrong was found
Summary[/B
I'm not sure what other steps I can take on my own to diagnose the issue or determine what's wrong. The system certainly seems stable since the OS update & permission repair, however it's still early.
Some suggest a power supply going bad, some suggest a bad logic board..
