battery??

Message #1 - Posted 2006/02/09 - Cato

The date on all new documents is 1904. I think this is a sign that the little battery in my IMac is cactus.
Is this correct?
If not, how do I change this date since date/time is showing correct date.

CORRECT - or you have unplugged your mac from the wall. Both will do this.

To reset the date & time simply go to your system preference (OSX) or control panels (OS9)

The battery is to keep all your preferences in tact WHEN you unplug your Mac from the wall. It always draws a trickle of charge.

Hi Cato ...

Absolutley correct. The little battery keeps the PRAM (Paramater RAM) alive when the machine is unplugged or turned off. Depending on what type of iMac you have, it's a fiddly, but not too tough job to replace it. Do a google for a service manual / 'pull apart' document. But first, find out what type of battery your iMac takes, and buy a replacement ...

How do I change this date since date/time is showing correct date?

All of the documents that you created after the time reset, but before you reset the time, will have the 1904 creation date. If you open and modify them in the application in which they were created, that will chabge the modification date.

You might be able to find a utility tohack the date if it's that important to you ... if using OS 9, use ResEdit - OS X, FileXaminer should do the trick.

Hope this helps,

Mikey Mike

This happens sometimes, especially with laptops - just reset the date in the date and time control panel and all will be well. Yes you will need to adjust your files creates since the date was 1904 but just opening them and saving again should be fine. If after a restart the date reverts to 1904 then replace the internal battery - they are usually a 3.3 volt battery that you can buy for Dick Smith.

Thank you fo the replies. On earler systems it was possible to purge the PRAM. Can this be done in 10.4?

Turn on the computer and press and hold the Command-Option-P-R keys. Hold the keys down until the computer restarts and you hear the startup sound for the second time. However if your PRAM battery is dead then this wont help
