The 190/5300 are notorious for having the power connector lose connection with the motherboard. Give that a check as well next time you open it up.

So  I went to the tip finally to dump my old stripped and unwanted iMac and eMac carcasses and at the bottom of one of the e-waste bins, I happened to find none other than an Apple…

A drill press (or mill) and a 1/32 end mill below the parting line. Replace the battery, then I use beige caulk so if I ever need to get into it again then it's just a razor blade.…

I dont run a pram battery in my 475, I just use the double flip of the power switch method which bypasses that issue.

As james_w in the uk i'll add that I used this battery for mine : http://www.componentshop.co.uk/6v-4-5ah-sealed-lead-acid-battery.html(they also carry a 5ah battery of the same si…

Thanks, I did not know.

oh and what Doug said too... those TDK LC power supplies are known for not working,  they need all the filter caps changed. but in my experience if the psu is no good, the computer…

yeah cap that 650 too.  it needs is. for sure.  the only machines that ( need ) a pram battery is the quadra/LC 475/605 and the Powermac 6100. you will get no video.       Well the…

when i re cell them i always just use this... it works out really great. http://www.ebay.com/itm/UPG-6V-5AH-UB645-Replacement-for-UPS-Battery-for-APC-AP200-/191402741759?pt=LH_Def…

Can you test the voltage?  It's possible the power supply could be going bad and the HDDs aren't getting enough power.

Some years ago I rebuilt several batteries for the Mac Portable, and I found that by using a hack saw at the seam it was fairly easy to cut off the top and remove and replace the g…

Great, thanks for the tips guys, I'll give it another go with your techniques! @BadGoldEagle, gotta keep it cheap for now, so it'll have to be DIY!

Uniserver's method should work pretty well The only thing i'll add is that if you can't get it to crack take a sharp knife and score round the seal and try giving it another go (t…

This is known, has been posted about.

Damn.  Recap then.  I suppose I should do my Q650 at the same time - even though it works perfectly. Could a flat battery cause a problem like this too? I will test with the Zip …

I gave the battery to an "expert". He cracked it open and replaced the cells inside. Total cost was high but not unreasonably high, about 60 euros for the batteries plus fit. Kn…

sure maybe you have bad luck.  or maybe you need to recap them... that sounds like a good idea.

@uniserver - Two logic boards, both of which were working a couple of months ago, now display the same fault at the same time?  Is that not a bit of a coincidence?

Had a bit of a positive development which I posted about here because I couldn't find this thread (even though it was staring me in the face lol)... basically put a 3rd video card …

defor said: Any chance you'd be interested in parting with the 200MP (with or without the matching) name badge? I'd really like to reassemble my old system from college (nost…

I'd dump the 1400c - if you have a maxed out Duo 2300c, it's a much nicer machine and more interesting machine to play around with with although the keyboard is pretty horrible to …

I would try the basic basic setup. Pull all RAM except 2 x 16 MB DIMMS, A twin turbo card if you still have it or the oldest PCI video card in PCI Slot 1 (close to the CPU), conne…

If it is an older 9600, it may not be compatible with the 604ev CPU from your 8600. What is the CPU speed marked on the front of the 9600 case? Or if that doesn't exist, the mother…

My recommendation after owning all three would be the 1400c and the 2300c. The 3400c is notorious for failing as already mentioned, and 8.6 on a 1400c with 64MB RAM is perfect. As …

i have done about 4 of them different ways, the last one i did, placed the battery on a 2x4 and used a dead blow and hit the seam all the way around and it broke free , turned out …
