Re: Blinking

[Jerry Kemp]

I still have my G5, and it continues to run strong and without issue to this 
day.  Sorry you had problems with yours.   According to my Apple order form, I 
placed the order 22 August 2005, with arrival in early September.  As I recall, 
it was specifically ordered shortly after the announcement of the move to Intel 
CPU's.


Aside from upgrading RAM and HDD's, no other hardware mods have been done.

The G5 replaced an 8600, that had been used for 8+ years.  That was a great 
system for me too.  Only ever had one problem with the 8600.  As I left the 
military, the 8600 was in storage/transport for roughly a month and a half.


When unpacked, I had to "zap the PRAM" to get it going again.

Maybe I have just been luck with my PPC HW.

Rather than going to the G5 you could consider an old  Intel Mac that can run 
10.6. When my G5 failed I found a 20 in. 2009 iMac that would run my Adobe CS 
apps and likely most other software used with 10.4.11. You can add your MDD 
drives with external FireWire enclosure(s). The iMac can handle more RAM than 
an MDD and I think  a second monitor. And you get the benefit of a more modern 
web browser if you need it.

I will admit the dual 2.5 GHz LCS G5 that replaced my MDD dual 1.25 GHz  was a 
step up in speed until its power supply failed. The G5 PS is difficult and 
expensive to replace.


I still use a very old G4 Sawtooth with a very fast dual 1.25 GHz upgrade and 2 
GB RAM for many chores and it is only a little slower than my old MDD but its 
days are numbered.

Basing on my experience, if you really use your Mac everyday, adopting an
Intel one is way better than a previous one.
OTOH, if you just want to tinker with it, you'll likely love a G5 :-)

I don’t really have a ‘favorite'; we never got more than one or two here, and I 
never personally used one...I went from Windows PC’s to a second-hand G4 to a 
first gen Intel iMac for a few years, and then later to the 27” Quad i7 
mid-2010 I have now. 

(We in the IT department are the cobblers children of computers. I keep getting 
to set up everyone’s newer macs, but never use them. )

I know they used SATA HD’s and different RAM than G4’s. ISTR the card slots 
were different as well; they were pretty much completely different 
architectures from what went before.

Intel macs came along and pretty much replaced all PowerPC macs here within a 
few years. I surplussed the last G4 in the College about three years ago, and 
it had been sitting in a closet for a while before that.

Re: Blinking

[Jörg]

Hi Bruce,

Thanks. I know, this is the 4th PSU that's going South. I pulled my second
monitor, the 17-inch Apple display and the fans are running faster and keep
steady.

I hope to get some more years out of this one. All the other PSUs that died
before were Samsung, this one seems a bit louder but apparently also
stronger. I'm using all PCI slots and have 4 HDs installed.

BTW which would be your favorite (most reliable) G5? I would like to get
one eventually. Could I keep using my HDs, cards and RAM?

Best regards, Jörg.

Re: Blinking

[W.Adrian D'Alessio]

Someone here ( probably Bruce ) will know instantly what this means. But
until they get here you could try what I a lesser mechanic would do.

I would shut down and look at all connections. I would look inside to  see
if any sings of electrical odors or visible signs of burning was present On
any boards. I would pop the RAM and reseat it. I would pop any boards
present and reseat them. I would reset any non volatile RAM.

If the problem reappeared after a reboot I would disconnect everything and
take the machine outside for a bath.
 Placing it on a stack of newspaper I would pull all the cards and RAM.
Using contact cleaner or 90% rubbing alcohol I would douse it all and scrub
it with an old toothbrush. Paying special attention to contacts on card
edges and inside of slots. Looking for corrosion ( green gunk), or very
dull looking metal.
I would use a very soft paint brush  and more liquid to wash and scrub  all
sides of every board looking for soot, burn marks, broken contacts, bad
solder joints.

Rinse everything and look at how much grime  or airborne tobacco smoke
show up in the rinse on the paper. I have revived several Old Macs by just
doing this alone.

Blot it with clean paper towels to speed up air drying.

You might find that reseating things, or cleaning a dirty contact solved  a
problem.

Also on your model give the PMU button a tap.
You can find a diagram or photo online.

Some software issue may be involved somehow, but my gut tells me it is a
hardware thing. Connections are always the first thing to look at.

I see now that the monitor with the blinking button is getting dark on top.
