Clock keeps changing.

Every so often my computers clock keeps changing to the mid 70's ! Is
my computer half hippy ?? Anyone know whats up ?

Thanks.

 

That is a classic symptom of the PRAM battery dying. m.

 

Sorry,

Power Book G4 running 10.48. Less than 2 years old !!

Thanks.

Possibly PMU is being reset involuntarily? m.

 

On one of my Macs, this happened every time it lost power,
whether by utility drop or by turning it off. Replacing
the battery did not help. Apparently the battery charging
components were defective.

Solution one is just never turn it off and never have a
power outage. Since that is not feasible, solution two
is to configure NTP sync with other machines.

 

Thus spake Wes Groleau:

Which model Mac?

I was under the presumption that the PRAM battery isn't rechargeable, but a
sacrificial "replace every 5 years" one.

Which means that either your replacement battery is bad or the other
circuitry which connects the battery to the PRAM is wonky.

 

That would be four replacement batteries in a 350-MHz slot-loading iMac.

My other identical machine does have a charging voltage across the
battery connectors when plugged in but otherwise turned off. And
I did use it to recharge a battery discharged in the first machine.

I thought the same as you until I read otherwise someplace I don't
recall.

Either way, NTP makes it irrelevant. Every time any of my machines
boots up, it asks all the others for the correct time. And several
times each day, all of them check themselves against one of a large
collection of NTP servers.

You can set up a simpler version of this by the GUI pref panes.

After the christening of his baby brother in church, Jason sobbed
all the way home in the back seat of the car. His father asked him
three times what was wrong. Finally, the boy replied, "That preacher
said he wanted us brought up in a Christian home, and I wanted to
stay with you guys."

 

Yes that whats happens to me also. Pain in the butt when you are on
the move all the time and not connected to the web.
