I want to see if anyone can shed some light on the problems I have been having with my Powerbook:
Powerbook Wallstreet, upgraded with Powerlogix 466, 256 Ram, IBM 20gig hd, Running system 9.1 Problem: After the system has been shut down overnight, the Powerbook will have several start up problems including bombs with various errors such as bus error, illegal instruction, etc. and freezes. It takes several forced re-starts but it eventually goes through and makes it to the end. Once a successful start-up is done, it runs all day fine without any problems. So far, I have re-installed the system software twice (I was running OSX, but removed it thinking the problem was in there), checked everything that was possible with Techtool Pro, tried with extensions off, without any peripherals connected, without battery or cd in bays, zapped the PRAM, all to no avail. I saw about resetting the Open Firmware command and tried this also. I was not able to bring up the screen using the key command, using System Disk utility from Apple, I can check the command manually and hold the keys down to bring up the screen, but then it will not allow any typing to give commands (frozen?). I have seen some feeds referring to the PMU unit as a possible culprit. I think the back up battery is also history (it is a few years old now), does anyone have any ideas or had similar problems that can give some insight? And, is there anyway of checking boards such as the PMU outside of shipping the system off to a service center? I appreciate any help, thanks.
