| PB 165 clock madness |
Posted by: croissantking on 2023-10-08 10:04:07
I only needed to open the Date and Time control panel under System 7.1 and it sorted itself out. I am really intrigued by this bizarre solution as I was sure it was a hardware problem. Obviously, the clock needs some sort of initialisation routine after the battery is replaced, but the code was not put into System 7.5 and later, probably got forgotten about. I wonder if the 7.1 Date and Time control panel will do the proper reset under later OSes.
Thanks @rollmastr |

Apparently 7.5 is kinda buggy on these machines, I just saw your other thread about the missing gray scales on the menu bars and such. |

Just to update with more detail - I had the PB apart this evening to swap out some RAM. This means I had to unplug the cable that goes to the interconnect board and therefore also the PRAM battery. On putting it all back together, the clock was in fast forward again.
You do have to boot into 7.1 to get it reset properly - opening the older Date & Time control panel under 7.5.x won’t do it. So keeping a 7.1 System Folder on the hard drive is a must if running a later OS.
As long as the backup battery keeps the RTC powered, I don’t expect it to go haywire again. |

I’m just mindful of the practicalities of trying to boot an earlier version on a Powerbook that’s set up with 7.5.
I have a friend with a 165c that this presumably applies to - we’ll see. Need to order more VL2330s… |

Another solution would be just to use 7.1 instead of 7.5. I’m actually considering this. |

Sorry for reviving this old thread. I was looking for information on this topic and thought it might be helpful to continue the discussion here. If this is not appropriate, please let me know.
@croissantking : exactly same problem on my PB165c. Unfortunately this machine wont let me boot OS7.1. Does it need some kind of system enabler?
@alexGS: do you have a valid Solution for your friends 165c?
Best Regards

Hello! Reviving threads is no problem.
Yes, I think the 165/180 use enabler 131 off the top of my head, maybe it’s a slightly different one for the colour models. You can find everything you need on Macintosh Garden. |

use the legacy recovery CD installer or the restoration CD, either should have a 7.1 install for the 165c. |

Thanks a lot for your help!
Booting was successful into 7.1.2 with enabler 131 on my Powerbook 165C. I was able to change the time and date.
After switching to the 7.5.3 HDD image, the time and date display remained correct and could be changed without any issues.

Well done. You’ll have to repeat the process any time you have the machine open! |
