When did MacBooks became famous for "bad solder joints"?

> When did MacBooks became famous for "bad solder joints"? There has been more[1] than one[2] case where GPUs in MBPs stopped working because of bad solder joints. And ifixit has a guide about how to fix your mac by putting it in the oven[3] to reflow the solder joints. 1: https://www.macupgrades.co.uk/store/product_info.php?product... 2: https://www.apple.com/support/macbookpro-videoissues/ 3: https://ifixit.org/blo…

More than one case in 20+ millions units sold?

I'm not sure that qualifies as "famous for".

> they have tremendous brand loyalty, but will need to be more careful in the future. Does that really matter though? I was just discussing this with someone over the weekend... his thesis was that people buy Apple because of branding, which might be true as far as the majority of customers are concerned... But for people like me (powerusers), MacBooks are simply the best possible choice. Everything else is either ad…

You claim to be a "poweruser", but then go and speak out of pure ignorance when it comes to Linux. You say "Apple hardware is beyond superior", when in reality Apple glorifies form over function with soldered, unserviceable parts (and actively lobbies against self-repair), and removal of ports (very anti-poweruser, if you ask me), all of which turn their laptops into disposable gadgets meant for the consumer demograp…

Apple hardware is good-ish. For proof you should look at the equivalent laptops from Dell etc and notice that they are cheaper, but not by much. Beyond superior? Nope. They still have better screens (colors not number of pixels!) and faster storage, but that's about it. And they fucked up the keyboards lately.

The one thing that makes Apple crap still superior is the HW/OS integration. I switched from Linux to OS X because of that, not the actual hardware.

Back to the power something, I do custom embedded Linux-es for a living. I still would like my base OS to "just work". systemd... can't trust Linux any more.

From what I've read, it's stable at ~92°C.[0] That seems damn high to me, but then I'm most familiar with desktops and servers, where you can cool far more aggressively. So is long term ~92°C hard on CPUs? 0) https://www.cnet.com/news/apple-macbook-pro-speed-throttling...

My old MacBook Pro I had for more than 5 years is 90% of the time around 100C. Whenever I'm working or playing. It's still working good.

100C is the boiling point of water.

100C is the boiling point of water.

So what? What's the boiling point of water got to do with anything? Is your CPU made of water?

The article made it seem like this only affected a small number of units? Their quality control probably doesn’t look at every single unit. Although it’s interesting that they didn’t find it at all, since reading HN and reddit gave me the impression it was very widespread.

Apple always claims their issues affect a small number of units. I have seen zero people that tested the i9 MBP and did not see major throttling. The issue is clearly the result of a fundamental defect in how they were managing power and thermals.

> affect a small number of units

Same story with the keyboard that was a fundamental enough design flaw to include 2 design bandaids in as many years.

No but your lap is (mostly)

When people say the ‘CPU’ in this thread, they don’t mean the whole main computer unit, if that’s what you’re thinking. They mean just the little chip inside. There’s a cooling system so it isn’t actually anywhere near that hot on your lap.

I hope there is no water whatsoever in your chips.

True. But I've used laptops where the fan exhaust was unbearably hot. And I'm sure that was much cooler than 90°C.

So maybe someone could check exhaust temperature on a 2018 Macbook Pro with i7 under heavy load. I get that the exhaust ports are on the back, near the display hinge. But that still might be iffy, for those who cross their legs.
