The battery help...

Message #1 - Posted 2006/08/20 - dale

Hi,

I just replaced my G5 BATTERY with a new one as the clock keeps going back to 1970.

Now I replaced it yesterday, I shut down started the G5 up in another 12 hrs and it was 1970 again

A brand new battery, how come not holding charge?

Does anyone have this prob?

I read that something about the PMU.

Should I do that?

Thanks for any advice

Are you disconnecting it from the power supply? Regardless of the battery - Unix will reset every time if you turn off the power at the wall and/or pull the plug.

Yes,

Every time I turn G5 off, I turn mains power off from wall.

Then that would be your problem. Get a good quality surge protector - and leave the power on at the wall.

Unix might but OSX does not. The battery should keep the system time and date fine - mine certainly do e.g. we unplug all our computers from the wall for the night if there are thunderstorms coming and no problems with time/date.

One solution is to sync it with a time server (an option in the date/time preferences). This is ok if you are going online all the time. However, it would suggest its either a bad battery (test on a multimeter if you have one) or may point to a faulty motherboard in which case take it back.

Have no idea what you are doing - but Unix will reset to it's creation date if disconnected from power. Story ends.

HI Greg

Yes Im sure Unix does but not OSX. Try it.

Hey Nigel - Unix resets every time - and as OSX is based on Unix, so does it. Every Time.

Hi Greg

Yes I know OSX is based on UNIX - its one flavour amongst many of UNIX. All Im saying is unplug your mac from the wall overnight, restart it in the morning and see what the clock says - bet you its not 1970. Have a great day. Cheers
