Nope, just a normal boot, which is reassuring. Installing patched Catalina now.Now that it tries to boot ie. powers up do you get diagnostic led action?

I agree about the 2012 Macbook Pro, those are just great machines. I have a 2012 13” i7 with windows/mojave/catalina triple boot and it is just rock solid.Dig out the 2009 MacBook Pro 13 inch from the basement, where I store lots of my old techs. Removed old Windows installation, installed MacOS Ventura which is still being supported by Apple at this point. Dear to say, Core 2 Duo is really struggling with MacOS Ventura.
The laptop heats up pretty quickly with just few Safari tabs open. Webpage is rendering really slowly, especially webpages with lots of ads. Opening applications are slow as well, even with SSD installed on this laptop.
However, this thing still is capable to edit office work with online version of Microsoft Office, still able to watch videos and do some basic computing tasks. I just have to be really patient with this machine and understandable this isn't going to be as fast as newer computer.
What I found is that jumping from 2009 MacBook Pro to 2012 MacBook Pro, the difference is night and day. I tested MacOS Ventura on all unibody MacBook Pro (excluding 2008 15 inch), only 2012 MacBook Pro can run Ventura in acceptable speed.
For the Unibody MacBook Pros, Ventura is probably the highest OS that I am willing to go. Anything past MacOS Ventura is laggy mass even on 2012 MacBook Pro.

What a great year of Macbook Pro.
This looks more like a casing of a capacitor than IC to me.The front casing of a high-voltage switching IC.
It's a TO-220 case (common with transistors).This looks more like a casing of a capacitor than IC to me.

Oh, I see. The size was difficult to judge from the picture and, to be honest, I haven't followed the developement of power management IC for some time. Not my cup of tea.It's a TO-220 case (common with transistors).

I suspect if I got a good look at it, the rest of the device will still be stuck to a heatsink of some description. Anyhow, definitely a catastrophic failure.Oh, I see.

There is probably a screw holding it into the heatsink. There might also (or might not) be a thermal pad or mica insulator sheet between the device and the sink.I suspect if I got a good look at it, the rest of the device will still be stuck to a heatsink of some description.

What I did with an early Intel today....
Saved a 4,1 White MacBook from the recycle bin that is in BEAUTIFUL shape. Just installed 4 gigs of Ram, an SSD and a fresh install of 10.6 Snow Leopard.
Needless to say, the machine won't boot, and doesn't give a green light when plugged into a MagSafe charger. I was hopeful I could salvage some components but apart from the hard drive caddy and the case screws it looks like the machine is completely FUBAR'd.
I'll second that! Eek...I commend you for even trying!![]()
OMG... I think a tetanus shot and a Level A Hazmat suit wouldn't be an exaggeration with that. 🤮@DouglasCarroll gave us a sweet story about a beautiful saved A1181.
Now it's time for me to give you a story about one of the nastiest MacBooks I've ever come across in a recycling bin.
My condo's electronics recycling bin can be a veritable Vegas slot machine of electronic goodies. I've scored a working HP G36 laptop, a working Samsung Series 3 laptop (the latter of which had a functioning battery!), plus a needlessly massacred Thinkpad R61. I'm typing this out on the same gross Razer keyboard I fished out of that bin.
Today, while I was taking a trip to return a spoiled rainbow trout I'd gotten from my local grocery store (which seemed fine, until I opened up the plastic wrapping), I found a complete A1181, just sitting there in the bin. Opening it up showed there was signs of moisture on the screen, along with the lines and splotches that signified a cracked LCD - a total red flag. Still, I couldn't pass it up. Something told me it wasn't a good idea to bring it to my usual work space, so I quarantined it to my bathroom.

What the - what on earth happened here? The browning suggested to me the presence of a liquid that got burned on the battery surface. Maybe there was a battery leak? The battery itself seemed intact though with no signs of bulging...

I've seen water/liquid damaged MacBooks before, but nothing severe enough to leave the underside of the topcase browned like that. If it was something like juice, wine or beer, it would have surely left some kind of tell tale sensory cue (a colour, a smell, or a sticky residue on the keyboard). Everything was moist; the RAM and the hard drive, especially. It was at this point that I decided to glove up, something I've almost never done when dealing with used A1181s, even ones with insides caked with pet hair and dead bugs.

Good Lord. I know that has to be the result of corrosion and not mould, but it looks enough like mould to give me a serious case of the ick. I really want to know what happened here. Was it left out in the rain and then thrown in a storage bin somewhere?

Apart from stuff on the Internet, I've seen some machines that have been used and abused in my time in Mac repair, and as an early Intel Mac enthusiast (I still think about the beat up 4,1 I got once which used to belong to a private school) but nothing I've seen yet has been on this level. At least with DOA Macs, I've been able to salvage parts like the speakers, heatsink/fan and WiFi card.
Ah well. Lesson learned. Don't buy discounted seafood, no matter how "fine" it may look in the packaging.
You mean they are physically there but not visible in the About? Did they show originally when you first got it?OCLP'd the cMP up to Monterey. Once it had shaken itself a bit, it occurred to me to look at the 'About This Mac' page.
One CPU and one set of RAM is 'missing '.
Rats. But then I was going to be redoing the processors anyhow, at some point. That point just moved closer...
Yes and yes. But if I fire it up with a live Linux, I see all eight cores. Still only 8 of 12 GB of RAM, though.You mean they are physically there but not visible in the About? Did they show originally when you first got it?
Well, that is weird. 😵💫Yes and yes. But if I fire it up with a live Linux, I see all eight cores. Still only 8 of 12 GB of RAM, though.
