Airplanes have bags/boxes to throw li-ion batteries into and extinguish any particular fire. The law is that you can only bring aboard Li-ion batteries of size 100 watt-hrs or smaller on any airplane ( https://www.tsa.gov/travel/security-screening/whatcanibring/... ). I think the airline crews are confident they can handle 100 watt-hours worth of burning, but no more than that!

You can't extinguish a lithium ion battery fire by smothering it. The fire creates its own oxygen. You can contain the fire, and you can immerse it in enough water that it cools below the burning temperature and shorts out through the water.

I'm not sure if they are smothering the fire. The strategy seems like it's just a safe place to keep the fire until later.

You won't have buckets and buckets of water on an airplane. You need a solution to safely contain the fire and keep the passengers safe.

This is the literal reason I switched to OSX. I dislike the impractical design of Macbooks - horrible connectivity and no way to swap batteries. However the combination of 15 hrs battery life + closing the lid and it not melting a hole in my bag trumps any negatives.

One interesting tidbit is that Macbooks will (don't know since when) start booting up if you press any key after having shut the laptop down. That's a bummer when you want to go clean your keyboard and don't want the laptop running at the same time.

Same issue here. 2020 Intel MBP, and when fully shutdown, pressing any key will turn it on. I would far prefer have a single, explicit power button. They even have one that seems as if it should be the power button (the touch ID sensor/key).

I have had some sort of problem with battery discharging on my MBP after shutting down fully from Windows. I can't use sleep/hibernate on Windows at all because it crashes upon restarting, with a kernel panic that is reported to Apple next time I start MacOS. That seems to have to do with initiating the Touch Bar. Things are fine when sleeping or shutting down from MacOS, but three times now I have shutdown from Windows and disconnected from power, then the battery is almost fully discharged (1-2%) when I turn on the computer less than 24 hours later. I don't understand what might be happening while it is fully shutdown.

I stopped using my Microsoft Surface Pro because it had the same issues. It's a clusterfuck of bad design decisions at Microsoft, the most offensive one being that they prioritize the execution of their scheduled spyware upload (telemetry) over honoring the agreement with the user that a sleeping PC will remain asleep unless the user takes action. It'll even install updates at night and then make reboot sounds to wak…

I was chasing this issue with my previous desktop which, at the time, was in my bedroom. I've always preferred sleep/hibernate over shutting it down but when Windows decided it knew better and to constantly wake it from sleep in the middle of the night to do updates, filling my room with light from all the case/fan leds, I was about ready to go Office Space on the thing. What was worse, it wouldn't go back to sleep a…

Try disabling Windows update’s ability to wake via GPO.

Having neutered Windows update my PC actually feels like a PC again.

I’d recommend just using a long term service channel version of Windows. It’s designed for embedded systems like MRIs so I doesn’t do any of the auto install and restart crap. Also doesn’t have the telemetry or most any other bloat ware Windows usually comes with.

> doesn’t do any of the auto install and restart crap That's misleading. LTSC version does everything regular versions do exactl wrt automatic updates and wakeups. Only difference is you can disable these with group policy in enterprise versions (which ltsc is)

You can absolutely disable them in the Pro and Home editions.

Far be it for me to defend Microsoft here, but I feel like if you leave unsaved documents open overnight, you are asking for trouble. Why a person would ever walk away from a computer without saving is beyond me. This whole post is actually pretty confusing to me. I don't use Windows that frequently myself, but my work laptop, my wife's laptop, my child's laptop, and my Surface Pro 1 all have Windows 10 on them, and…

> Why a person would ever walk away from a computer without saving is beyond me. Because it's extremely convenient and I don't remember ever losing anything on my Mac. I close the lid in the evening, open it the next morning and everything is there exactly like I left it. MariaDB is still running, my IDE is still running, and I can jump right in. Day after day after day, my uptime is usually the number of days since…

The longest I’ve had my work laptop up is around 40 days. Usually shorter, as it slowly corrupts itself until it BSODed with memory management or page fault.

I'm not unfamiliar with Linux and I've been looking into switching recently after a long string of Windows "features" causing problems, but unfortunately gaming isn't the only area Microsoft has an advantage. Linux still doesn't support HDR, for instance. It also has a lot of problems with desktop compositing, because the switch from X to Wayland is at the point where neither of them are good options. That's not even…

Why is anyone interested in HDR? 16M colors should be enough for anyone. I do have minor issues when scaling my 4K screen to a lower resolution, and starting a fullscreen game, but that’s about it.

It's not about the colors so much as the fantastic contrast, it really makes games/videos feel more alive.

My 2017 MBP that was fully spec’d out is both the most expensive and worst laptop I’ve ever owned. -Rarely ever goes to sleep -It’s the same model Facebook returned a few thousand of because it randomly voltage surges the USB-C ports and fries stuff plugged into it. Apple refuses to acknowledge this, even though a bad voltage surge blew out the left speaker. -Keyboards been replaced four times -NVRAM needs to be rese…

I'm missing the relevance here? Are you just trying to point out that MacBooks are also imperfect? I had a 2017 as well. And before that a 2013. And since then a 2019 16-inch and a 2020 M1. Yes, the 2017 sucked balls in ways that I can't even begin to count. The 2013 was f*cking flawless. I've similarly had almost zero problems with the 2019 16-inch MBP or my 2020 M1. There's just something especially crappy about th…

Oh yeah I loved my 2010 and 2014. Looking forward to the M1X. The 2017 is just a special kind of awful

My XPS 13 on Ubuntu while sleping randomly turns on in my backpack and tries to melt a hole/burns the battery to 0. So I think at least SOME of it might be hardware related.

As I understood it, it's an ACPI configuration, more or less 'forced' by Microsoft, to ensure this cool new S0 is the default. See [0] [1] and [2]. The fix/work-around is to tell the kernel to not do that, and just use traditional S3 sleep. Adding `mem_sleep_default=deep` to your kernel cmdline should fix it. Been doing this on my XPS13 for 3 years now and it's fine. [0] https://bugzilla.kernel.org/show_bug.cgi?id=19…

S3 is no longer available on newer XPS notebooks (e.g. 9310). S0ix works fine with Linux but I've found it typically requires tweaking and testing.

dmesg | grep ACPI | grep supports [ 0.193967] ACPI: (supports S0 S4 S5)

sudo cat /sys/power/mem_sleep [s2idle]

I never understood why I should be hibernating instead of suspending so I can't talk about that - but I haven't seen a laptop unable to suspend for years. That could be luck and not buying laptops with terrible linux support but I wouldn't paint the situation as this tragic. The experience out of the box is still crap because the ACPI signals from the hardware are often a complete mess - but disabling most of them ge…

> and not buying laptops with terrible linux support but I wouldn't paint the situation as this tragic. Please tell me the name of a laptop which has excellent support for Linux. At this point, I'm ready to go out of my way to spend more money than I can afford if that gets me excellent Linux compatibility. I know, for a fact, that AMD based ThinkPads don't qualify. The Intel based FrameWork laptop has issues with su…
