G3 Pismo Powerbook - power? and bootup issues, won't see hd?
I have a G3 Powerbook Pismo/Firewire which has been old faithful (and I’m fond of it, I even met my lovely wife on it) but I think this could herald the end, or at least the end of me spending any money on it...I’m running OSX.3.9 with 128meg of RAM.
I haven’t run with a battery for at least a couple of years, until recently I was living in Australia and they were too expensive....my battery was getting old, when my original yo-you ps/charger suffered the infamous insulation breakdown/corrosion near the terminal, it shorted out and the battery died that day. I replaced it with a new updated-looking yo-you with the white power cord - the old one was clear, and was breaking down inside, you could see it arcing and I’d replaced it with a generic cord....the old yo-yo also seemed to cause a great surge when it was plugged in - a big arc when it hit the contacts. new one didn’t.
I was trying to solve some network printing issues on it - with an HP 7210 Officejet, where their support stuff suggested printing issues could be solved by booting into Classic to install the OS9 drivers (I had previously done this by stealth by booting into a Classic partion and transferring the files over, I didn’t know you could boot into full OS9 mode on an OSX volume)
When I booted into Classic I couldn’t remember the filename of the installer I wanted and wasn’t configured in Classic for the net, so I tried to go back into OSX - then the fun started.
I could not get back into OSX - when I booted with the option key, I could see three system folder choices- the OS9 one, the OS9 partion (also with OS9 on it) and TWO OSX folders to my surprise - I had recently replaced the internal drive with a Samsung drive, (the Seagate drive rather prematurely started making clacking noises - haven’t RMA’d it yet, but it’s under warranty. I haven’t had good luck with harddrives in this laptop, this one’s my fourth....I did check temperature around the drives once, and it was within the manufacturer’s tolerance, but just....and no, the fan on the left never runs, I wish it would, it’s a lap-baker. Fan came on just once or twice, I wish I could force it to run more often.) and assumed that the cloning process (I used Carbon Copy Cloner) was responsible. I didn’t have any choice but to clone, because all my installer disks are still on their way from Australia with the rest of my stuff...
Anyway, I chose the OSX folder that had the mac face, as I seem to remember that indicates the system drive. Then it wouldn’t boot into OSX and eventually wouldn’t boot at all, just the blinking system folder/questionmark (I have noticed since installing the new drive it would always do that for a while then boot) - then it wouldn’t do anything at all.
Went to bed. This morning got a little more response after reseating/p-raming etc. I may have also accidentally gone into programmer mode - got the beep and the sleep light flashed rapidly, but it seemed ok in this regard when I disconnected power and pushed reset (remember there’s no main battery in this laptop)
I have not been able to boot with the ‘new’ hdd at all, it was working fine til all this started.
I have a Firewire caddy/cartridge system and a laptop adapter, also a USB mini drive box, by putting the old laptop drive in the self-powered (not bus powered) Firewire box, and putting the ‘new’ drive in the USB housing, I was able to get it to boot, although it took ages and ages, and a few different configurations, it seemed to hang at the loading Apple file system thingy...
So I am wondering if the swap OS thing was a coincidence, or whether the rebooting etc sent the power supply over the edge - the bottom of the yo-yo says it’s 24vdc, but testing without load (and insulating the outer sleeve to avoid a short) it’s reading around 16-17vdc. I don’t know if this is open-and-shut but I’ve seen marginal PC power supplies prevent hard drives from getting up to speed. On the other hand, since I was testing it without load, it might have been in some low-power mode.
I also wonder about the PRAM battery, occasionally I have to reset the clock if it hasn’t been plugged in (which seems to keep the PRAM up) - since there’s no main battery - but unplugged the PRAM (original) battery’s reading about 6.4vdc.
I then put the old seagate drive in the laptop, and was able to boot off it - is it just that the new drive’s faulty? I’ve been able to run disk utility and norton’s over it, and it hasn’t found any major faults - a couple of minor one’s I’m attributing to it not being the boot drive -so I’m confused...it’s accessible whilst it’s in the powered firewire box, files can be opened etc - but not when it’s in the USB enclosure.
Is it just the power supply? Am I going crazy? do I just throw more money at this thing? Maybe it's time for a replacement, but I'm not sure what I'd buy...
All suggestions appreciated.
On another point, I saw some mention of heatsink paste - there's a sort of pad on top of the heatsink thing under the heatshield, is that a replacement for heatsink paste, or is that underneath? Is it worth redoing? Thing has always run hot...
