From: aa778@cleveland.Freenet.Edu (Fred Horvat) Subject: CPU battery Date: Fri Aug 21 09:25:21 1992 Hello, I recently had a problem with my Portfolio that I'd like to share. My batteries where running low (I got the Low Battery message) so I replaced the Ni-cads with a fresh set and then I started getting some strange error messages at the DOS prompt. Divide error, Divide by Zero........ real winners. So I pulled out the batteries and got out the AC adapter figuring that one of the new batteries may not have been fully charged. I plugged it in and pushed the reset button on the underside of the Portfolio and the same thing happened. I thought at this point the Portfolio had died. I thought about it for a while and remembered that even when you turn off a desktop computer for 30-60 seconds there is enough electricity still zooming around in the PC that memory still contains all the information. That's why for Virus Check programs to work properly you need to do a cold boot after the PC has sat turned off for a couple of minutes. OK back to my saga. Well to make matters worse on the Portfolio there is a lithium battery built in to the motherboard. This is why when you change batteries nothing is lost in memory because there is still a battery working. I needed to clear memory completely and do a cold boot. I took out the batteries and unplugged the AC adapter and let the Portfolio sit for a few days (from what I read somewhere a couple of hours should have done but I wanted to be real sure). I put in a fresh set of batteries and it came back great. I still had to restore all files but hey I back up after every session so no big deal. The moral to the story if you get heart stopping messages remove all external power sources let the Portfolio sit for a day? and put new batteries in and cross your fingers it just might work. -- Fred Horvat, aa778 Your Atari Portfolio SYGOP And all your Atari SYGOPs,xx004
