Try charging on the right and not on the left

Re: Try charging on the right and not on the left
#72I noticed my 2019 MacBook Pro physically hot to touch even after being idle for 8 hours at night. Now I unplug my USB-C monitor and USB-C-to-USB-A adapter at the end of the day and that has solved the problem. Now when I come to the machine in the morning, it is nice and cool, and I plug-in my peripherals again. It seems Apple has noticed this sub-par pro performance and moved back to the MagSafe charger in the lates…

My late-2020 MacBook Pro also stays warm (even hot, sometimes) while supposedly sleeping. It can also no longer charge on the right side, that just stopped working. Had to rearrange my desk to satisfy the power bugs on the laptop.
Quality has gone way down, I don't quite see myself ever getting a Mac laptop again, after being on OSX laptops ever since OSX 10.0 came out.
Re: Try charging on the right and not on the left
#73This doesn't make sense, and I'm a bit worried: I "cheaped" out and have a "left side only USB-C" MBPro from 2019. Should I understand that having any kind of load on the measly 2 ports I have on my 1600€ computer will lead to abysmal performance? Like, attaching a USB hub to add basic necessity like HDMI or USB A?
I have a 2019 MBP that runs hot because it's supporting an external monitor. The year before every laptop became a WFH desktop, Apple decided that running an external monitor could be a massive heat issue and nobody would care. It's literally burning out my work laptop, and soon I'll have to ask IT for a new one. Apple doesn't care, though: they already got paid. As I understand it, though, most of the thermal issues…
If you're worried about thermal damage to your laptop, maybe you can prevent it? Some ideas:
- Leave the laptop screen open. You can turn off the screen by setting its brightness to the minimum setting.
- Power your USB devices from a powered USB hub.
- Point a small fan at the side of the computer.
- Clean the laptop's cooling system of dust and lint. Keep the laptop on a stack of books so the intake vent is raised above any surface that can collect dust.

Yeah, Apple hardware may be worse than it used to be. But as far as I can tell, it's still at the top. Can you point out a company that consistently makes better hardware than Apple does?
Literally any random gaming laptop on Amazon probably won't have any of these problems, while also having ethernet ports etc.
They'd also cost half as much and allow you to upgrade disk and ram.

Power draw from the GPU is a lot lower on Monterey. Still not as good as driving only the internal display, but about ~40% lower compared to previous OSs. Lower power mode also helps another 15%.

#76Earlier this year, suddenly had my 2017 MacBook pro freak out and freeze on using the camera or screenshare: fans would go nuts and cpu meters were completely loaded. After reinstalling and upgrading the OS with no luck it occurred to me to check for dust. Indeed, there was much dust and after a good proper clean all is normal again. I used compressed air for best results.

> literally burning out my work laptop
Is there any actual evidence for running a CPU near its thermal ceiling causing premature failure vs a cpu running at a 10-20c lower temp?
When I hear people saying things like “my PC is dying”, this is usually due to thermal throttling from dust buildup or malware running causing excessive CPU usage. It’s not like the CPU is getting crispy around the edges and parts of it stop working so only a smaller portion is still available to do work or something.
There seems to be a lot of conjecture out there about the longevity of a CPU vs heat, but I’m wondering if this has ever been actually studied in a scientific way. I understand that electromigration is real, and it could e.g. cause a trace to eventually blow out.
This is the closest thing to a real scientific explanation that I could find https://www.reddit.com/r/hardware/comments/5l3ufj/is_there_a... but it still doesn’t go into why / how / the physical mechanics of it.
https://forums.tomshardware.com/threads/cpu-electromigration... Also attempts to explore this in a fairly scientific manner, but it’s focused on over-volting and overclocking vs normal (especially mobile, where CPU voltages tend to be less tweakable) operation.
TL;DR In my experience, CPU/GPU temps don’t matter as long as they are not causing throttling. Running within a few degrees of the thermal limit (Tjunction max ) 24x7 for years won’t affect the longevity of a CPU/GPU in any functional way, and won’t cause slowdowns, only failure, possibly of a subsystem like USB or other on-die subsystems. If anyone has anything showing otherwise, please share it!

The laptop is practically new. I keep it standing vertically on its side, with the lid closed, plugged into an external monitor. It's still uncomfortably warm to the touch.

I don't care about power draw, I care about the fact that my laptop gets physically too hot to touch while running an external monitor.
