From: DanKaye on 6 Oct 2005 14:12 I hope someone can help me. Here's the situation: I have an old 500 series Powerbook (540?) and it's been sitting for like 3-4 years with the ac adaptor plugged in and batteries in it. (I know this was dumb, to keep it plugged in, but I just kind of forgot about it there...) So I go to pull some files off this old 500 series PowerPC laptop the other day, and I opened up the top and it turned on (from sleep mode?) right away, I began exploring it and pulling stuff off onto a floppy (no cd - this unit is like about 10 years old...) So anyway, all was well, until after about half an hour, and then a message came on saying the battery was running low (?)(I thought I was running on AC!) and it would shut down. So it shut down. Now, I cannot get it to restart. First of all: I cannot even remember how to turn the power on. It has a key in the upper right of the keyboard with a left pointing triangle. As I recall, this is the Power button, right? But if it is, it is not working, I cannot get this thing to turn back on even though it is still plugged in to the wall outlet. I took out and re-seated the batteries, and the power cord, but still no luck. Why did it turn itself off due to low battery power if it is plugged in to the wall? And how do I get it back on, and working purely through AC, not the battery? Any help would be greatly appreciated. I have some old files on here that I would really like to archive onto floppy and then cd. Thanks for your help!

You may want to download the "Getting Started" manual from the Apple support site. It has a fairly detailed troubleshooting section.

At first it didn't work, but then after leaving the computer sit overnight, it started again. I turned it off after transferring some files onto a disk, and unplugged it to move it, and now once again it won't start! This makes no sense to me. If it was the Power Supply it would not have worked at all, but it did work, until I shut it down. But now it won't start, again.

Wow. You had it running, were able to transfer files, and then shut it off again? Why in the world would you do such a stupid thing? -- Life. Nature's way of keeping meat fresh. -- Dr. Who

It booted fine after replacement. The PRAM battery for the 540 costs only about $10 (e.g., powerbookguy.com) - it may be worth a try. I assume you tried resetting the PMU again?
