Update: I got the latest A1052 to boot! The cables for the DC and battery boards were unplugged for some bizarre reason.

 

Anyway, it is, quite unsurprisingly, identical to the other one in every way except for one: it has sound from the internal speakers! Using the other's sound board, no less....

 

So, this means logic board, I guess? Could the speakers themselves have gone bad somehow?

Headphone jack. I had a 17” G4 with the same problem. Turned out the sensor inside the headphone jack was messed up, so it thought headphones were plugged in, causing the internal speaker to not work.  Apparently this was a common issue and some could be fixed with a shot of compressed air or isopropyl.

How could it be the headphone jack when the same sound board from the mute A1052 works perfectly in the other one?

 

Also, the Sound preference pane reports the output device as "Internal Speakers", as expected.

Oh, Wow! That's neat!!

 

No it wasn't too hard. Just had to resolder the contacts, which seems to be a common cause of inoperative power ports on these.

 

I did notice the writing on the battery cover, but it's not too noticeable, so I'm OK with leaving it there (besides, it adds character).

 

Did you want it back, now that it's in tip-top working condition?

No thanks, I had actually bought it off eBay (advertised as untested/broken) not long before just to harvest the CD drive bezel. I have an Indigo iBook that I got from shopgoodwill last year, in great shape except for that missing bezel.

2 years almost to the day since my last post here!

 

I finally have something that might be worth mentioning here: a free Dell UltraSharp 2007WFPB I rescued from a dumpster at the local transfer station.

 

It's intact, with no apparent cracks or breaks in the LCD (some hefty scratches, though), but it won't power on.

 

I suspect it's due to bad caps in the power supply, but before I spend $12 on the thing, I want to know for certain if that will fix it. Otherwise, I'll put it back where I got it (except the stand, as I have another display that could use it if this one's permanently shot).

And, 11 months later...

 

I actually have something worthwhile to post here:  I was just given a decent looking 2009 iMac!

 

It's the smaller size (22"?), and that's about all I know for now.

 

I'll post more when I dig in tomorrow....

 

In the meantime, here's a quick 'n dirty picture of it:

Before I continue, I'd like to thank @Cory5412 for re-integrating my 2017 Latest... thread with my 2013 thread, which I thought was lost until I accidentally rediscovered it a few days ago.

 

OK, so with that out of the way, let's discuss the iMac!

 

It's the Early 2009 20" model, with base 2.4 GHz Core2 Duo E8135 CPU.  I'm not sure of RAM, but I suspect that it's either 2 or 4 GB (I'll have to boot it up and check).

 

Anyway, I'm thinking of ways I can upgrade it to be a bit more useful.  However, being that it's at the extreme edge of what's considered usefully modern, I'm not expecting to gain much out of the effort, save perhaps for the experience gained in disassembly (I've never operated on any of these iMacs before; only with the G3 iMacs do I have any significant experience), and am aware that it's not a super cost effective machine to dump upgrades into, but I want to anyway "Because I Can."

 

That being said, I want to know if I can upgrade the CPU.  I've read conflicting reports on exactly what's possible, so I'm not exactly clear on the matter.

 

Be that as it may, if it is possible, I'd like to upgrade it with a Core2 Quad of some kind (allegedly, the Core2 Extreme X9100, Core2 Quad Q9100, and Core2 Quad QX9300 are at least mechanically compatible, as are the C2D T9900 and E8435, the latter of which was apparently Apple's top-end BTO CPU option for this model), because I think that would offer the best performance.

 

Aside from that, I'll at least want to max out the RAM (8 GB, I believe), and upgrade the hard disk (I have a 1 TB drive that's seen minimal use, so I think I'll use that).

 

Soo... thoughts?  Suggestions??  Comments???

What looks exciting to me is that you can use the Catalina Patcher on this model of iMac to install Mac OS Catalina. Big Sur might also be possible with a bit more work. In terms of maxing the computer out, I think you should opt for an SSD drive over anything else, even if its an $18 256GB drive. The computer will be considerably more usable and faster this way.

 

I still regularly use a 2010 27" iMac. I have installed an i7 870, 16GB RAM, a 512GB SSD, and an AMD RX560. My computer is still completely usable, and if I wanted to, I could even install Big Sur onto it. Unfortunately, I'm not sure this 2009 iMac will take quite as many powerful upgrades, especially in the CPU & GPU department (256MB of VRAM might be a bit rough to use, for instance), but I do agree that it would be pretty interesting to max the computer out just to see what it is like.

 

I'm sure there must be some sort of faster CPU that you can install. My 2010 iMac's CPU is just a standard Socket 1156. Do keep in mind that it might not be worth buying the absolute best CPU, but rather something very close to it. The absolute best CPUs for a given socket have inflated prices, and you are likely never to notice a difference.

 

Have fun!

@davidg5678 That's good to know!

 

However, I just made a mistake:  it's an Early 2008, not 2009 as I had originally said. 

 

So far, the main thing that changes is that RAM is limited to 6 GB DDR2, vs. 8 GB DDR3, and the GPU is a measly Radeon 2400 XT w/ 128 MB VRAM, so I seriously doubt Catalina would be a very pleasurable experience, especially with this iMac configured as is. 

 

I think I can maybe get High Sierra on it, though, and perhaps with an SSD and a GPU upgrade (if possible), performance therein will be decent., even with 6 GB RAM. 

 

We'll see...

OK, did some more reading, and it seems the Early 2008s don't work with quad core CPUs, which is too bad. 

 

However, I can upgrade from the stock C2D E8135 (2.4 GHz) to a C2D E8335 (2.93 GHz), which was available I think as a BTO/CTO option on the 24" iMac, which isn't earth shattering, but an improvement nevertheless (and, I can find them for about $10, so it's cheap). 

 

Next I'll research possible GPU options, as I don't think the stock graphics will perform terribly well on anything past El Capitan.

Progress update to self...

 

I just finished tearing down the iMac and giving it a good deep clean so it doesn't have all kinds of tobacco residue in it (it's not the grossest I've seen, but it wasn't great), so now it should run a bit cooler.

 

I didn't refresh the CPU/GPU heatsink paste because I don't have any handy, but I did install a 1 TB spinning drive, so while it may not be substantially faster, it will at least have more storage space.

 

Anyway, it's back together now, with only one extra screw left over :)
