Issues with my Powerbook-shaped Boat Anchor

I finally got my Wallstreet all set up exactly how I wanted it; negotiated with the seller for a working battery and found a cheap wireless card to stick in it. All was peachy. Then suddenly today it stopped working! Gordon Bennett!!

It’s always had an annoying habit of taking 10 seconds to do anything when you turn it on, i.e. startup sound, 10 seconds of black then screen and startup. Then I noticed it wouldn’t wake up from sleep sometimes, and you had to press command-control-start to reset it. Fine I thought, I’ll shut it down instead of putting it to sleep. So I did that, and still it wouldn’t start up today from batteries, no matter what I tried. I took it back to the office and plugged it in. It immediately whirred and the power light came on, then after about 10 seconds began to start up then gave me a bomb with a bus error. The trackpad wouldn't work so I restarted from the keyboard and after another 10 second delay it started up properly but somehow it had disrupted the space-time continuum and taken me back in time to 3am on 1 January 1901*. Oddly though, none of the other clocks in the building have been altered and 1901 seems exactly the same as 2007. Perhaps it has somehow transported itself into a parallel universe that is 106 years behind us, but somehow has left behind its essence in our own time?

Anyway, any thoughts as to what the blazes is going on and what, if anything, I can do about it?

*Heh, I drafted this post in word and it highlighted that date and invited me to schedule a meeting.

That is normal with OS 9. (Not OS X though ;) )

Reset the NVRAM.

Bad battery? Battery not charging for some reason?
I took it back to the office and plugged it in. It immediately whirred and the power light came on,
That is normal if the internal backup battery has been drained. It also happens with PMU or w/e reset.

Sounds like the lithium backup battery pack may be dead. Open up the case and get to the battery. Check to see if you get a 3.6 volt reading or higher. If not, the battery needs to be replaced.

After replacing the battery, reset the PMU/CUDA by pressing the reset button once for one second. Then, reset the PRAM. Yeah, I know. This will reset everything how you set it, but that's what happens.

Also, watch the power supply and rechargeable battery; make sure they're up to par.

Thank you gentlemen. The main power battery is brand new and has been working perfectly so I'm sure that's not the problem. I'm dumb so you'll have to explain a few things to me...

1. How do you reset the NVRAM?

2. Where is the reset button on these things? Does it have one? On the back panel it says "Reset=Shift, Fn, Ctrl & Start". Will pressing that reset the PMU/CUDA (whatever that is)? :)

3. How do you reset the PRAM again? Ctrl-option-PR is it?

4. Oh and what's this internal battery - is that the same as the PRAM battery?

Thanks [8D]

1. How do you reset the NVRAM?
hold down Command+option+O+F while booting and when you get a cli prompt (Open Firmware) type the following:reset-nvram (press return)

set-defaults (press return)

reset-all (press return)

After reset-all the Mac will reboot.

2. Where is the reset button on these things? Does it have one? On the back panel it says "Reset=Shift, Fn, Ctrl & Start". Will pressing that reset the PMU/CUDA (whatever that is)? :)
According to the documents I have that will reset the PMU (Power Management Unit). Wait a good 5 seconds before pressing the power button again after that though.
3. How do you reset the PRAM again? Ctrl-option-PR is it?
Command+Option+P+R while booting. Hold it down until you hear one additional chime after the initial one.
4. Oh and what's this internal battery - is that the same as the PRAM battery?
It is kinda an enhanced PRAM batt that can keep the computer running while sleeping for a while so you do not have to shut down to swap main batts.
Information about the Wallstreet and PDQ internal backup battery can be found here:

Thanks, is there any other way to reset the NVRAM? I have never been able to get the machine to go into open firware. It just boots up as per usual.

Oh blast, I think I pressed that about 10 times in quick succession, in between pressing the start button as well. Oh well, still works. You don't have any idea where to get the replacement batteries, do you?

Not that I know of. Have you tried holding down the keys while pressing the power button to ensure no timing issues?

Online vendors? Might be able to find em in electronic stores in a city.

Probably not. I'll try it. Thanx [8D]

Yeh, I got the part number from that link so I should be able to find 'em somewhere. Hope they're not too hard to replace.
