Date & Time always reset to 1904 upon startup - backup battery problem?

Message #1 - Posted 2001/11/04 - csong

Hi!,

I just bought a new iMac Indigo about a month ago. Since the last few days, I noticed that I have been receiving an error message upon startup that the date & time has been set to year 1904.

The sales personnel from Apple Centre told me that OS 9.1 had been experiencing this problem & asked me to trash the "Date & Time" preference file to solve the problem.

I have trashed the preference file a few times & still no luck. My instinct tells me that the internal backup battery is kaput.

I would like to know whether I can change the battery myself & what is the type of battery that I should get. Any suggestion will be much appreciated.

BTW, I have downloaded the pdf file from Apple Support regarding the procedure to change the iMac internal backup battery so I rather do it myself than having the iMac in the Apple Centre service dept. for 4 days!

Best regards,
csong

That's the first thing that comes to mind. If it's your battery than other things that the battery powers will also be disappearing. I don't have your model, so I don't know exactly what else you should check, but on my model things in the PRAM like amount of time in use, and control panel settings like mouse speed would disappear on every power-down.

Since I don't have your Mac I can't tell you how to get to your battery, but it should only be about a $10 part to swap out and see if it fixes your problem.

I've bought batteries from genuine Apple service folks that lasted as little as a year. Now I go down to a generic place like Batteries Plus when I need one, and get them for 1/10th the price. The info you downloaded from Apple should tell you what battery size/part number you need.

Good luck.

My new iBook does the same thing everytime there is a conflict. Any lookup will cause the date/time to do the exact same thing on a reboot.
