After my battery died, my second RAM slot says empty in system profiler

My battery is now completely dead after leaving it asleep for three days. I have removed it and am running from my power adapter. I tried my roommate's battery and it works fine. Now however, in system profiler is says I have 512 MB RAM and my second slot is empty. It showed 2 X 512 MB before the battery died.

Suggestions for getting the second chip back?

1.67 GHz PowerPC G4, Mac OS X (10.5.4)

When you use your roommate's battery, does it show up in System Profiler? Under the "Battery Information", you should see something like this:

Charge Information:
Charge remaining (mAh): 4297
Charging: No
Full charge capacity (mAh): 4431
Health Information:
Cycle count: 15
Battery Installed: Yes
Amperage (mA): 0
Voltage (mV): 12440

Yours may say "Yes" under "Charging".

If your battery is not full, and your PB is not charging the battery, then there is something wrong with your DC-In Board or/and logic board. It's cheaper to replace the DC-In Board.

If you are okay with using your PB always plugged in and want your RAM back, you could purchase a 1 gig RAM stick to go in your upper slot only.

Good luck!

Thanks for your post.
When I tried the other battery, the PB does charge the battery successfully.
In the System Profiler however, it does still only show the one stick of 512MB RAM.

So I should go with a new battery and a 1G stick of RAM.

Thanks for your help!

Glad to hear that the PB is able to charge! Before you get that battery, maybe you can first check to see if yours falls within the serial numbers of the recalled battery?

Apple will send you a free replacement if you qualify. (Just trying to help you save a few bucks!)

Thanks!
This battery doesn't fall in the call back. It is actually the replacement I got from the recall.

Thanks again.

dafall: Many of the batteries that were supplied as replacements under the recall have proved to be defective in much the same way yours has, and some of their owners have been successful in persuading Apple to replace the bad batteries again. Call 1-800-275-2273 and ask to have yours replaced.
