We use this exact same laptop at Red Hat, and meh! I like the laptop sometimes, but I've actually had plenty of times where it's more of a pain. For example, I run multiple 4k displays on my desktop, and using the Lenovo thunderbolt docking station with multiple 4k displays does not work. two 1440p displays are fine, but not two 4k UHD displays.

To prevent overheating on my X1 ThinkPad under Fedora I set the CPU governor to the power safe mode. As an added benefit it makes the laptop almost silent even when using all the cores/threads to compile huge C++ code base that may the memory usage towards 32 GB. Surely it compiles slower, but the slowdown is less than 25%

Can you elaborate on how to set the CPU on that mode? Is a command or BIOS setting? I would like to do the same on Ubuntu.

Given that IBM has transitioned to MacBooks for corporate use, have at least some Red Hat developers moved to MacBooks as well?

On the PC front, do you find that other workstations (Precision, Elitebooks) are better supported with regards to Linux and associated peripherals?

Earlier quoted context omitted.

According to the official documentation [1], the 13" M1 MacBook Pro also has this limitation: > If you're using a Mac with the M1 chip: > > On iMac, Mac mini, MacBook Air, and 13-inch MacBook Pro, you can connect one external display using either of the Thunderbolt / USB 4 ports. [1] - https://support.apple.com/en-afri/HT202351

To be fair, several of my work laptops had a similar sentence in their user handbook, but two monitors were possible if you connected the wires before booting the laptop. Really strange limitation, as it never scaled with bandwidth - so 4k 90+Hz was doable, but 2x 1080p60hz wasn't.

Some intel laptops (Ivybridge chips definitely, sandy Bridge probably) had such warnings because officially the chip couldn't support running three displays due lacking enough clock generators. Given the almost-analog nature of HDMI and naive LVDS, this meant trouble.

Thing is, Display Port has much more different physical layer derived from PCIE, and so connecting two displays by DP and running internal screen with LVDS worked just fine.

I recently acquired a ThinkBook 16p Gen 2, and while a different machine entirely to the ThinkPad, I must say that this is an _absolute beast_ of a machine. It's a total joy to use. It's the most fun I have had using a laptop since my first MacBook. Moving from the MBP to the ThinkBook has made me realize how... boring MacBooks are - not saying that's a bad thing. MacBooks do 'just work'. But the ThinkBook? The machi…

You have no issues with thermal throttling or inane power limits on Linux? Which kernel version are you running?

These issues were caused by buggy intel software back in T460-T480 era - lenovo considered the problem big enough to consider not using Intel thermal management code in future designs

Your comment is so incredibly divorced from reality. Plastic doesn't grow on trees either. Its production has huge impacts on the environment. Aluminum is highly and easily recyclable. In fact Apple makes their MacBook enclosures from 100% recycled aluminum. No other computer manufacturer can make the same claim regarding the production of their plastic body notebooks. The idea that plastic can be infinitely recycled…

> No other computer manufacturer can make the same claim regarding the production of their plastic body notebooks.

I seriously believe it's time we start considering Apple a religion.

Technology company HP Inc., Palo Alto, California, has a product and service portfolio that includes personal computer systems, printers and 3D printing solutions. Increasingly, the company’s products are manufactured using recycled-content plastics

All the ocean-bound plastic that HP incorporates into its products is PET. The company says its HP Elite c1030 Chromebook Enterprise laptop is the world’s first Chromebook made with ocean-bound plastic. The device also is made from 75 percent recycled aluminum and features a keyboard made from 50 percent recycled plastics

HP is using ocean-bound plastics in its products, with the Dragonfly is made of 80% recycled materials

HP has just launched new ENVY notebooks that offer creators the freedom. The ENVY laptops are also made from recycled aluminum

In 2018, we began implementing the use of an innovative bio-based packaging made from bamboo and sugar cane fiber. The material is not only 100 percent biodegradable, it is lighter than previous packaging and its strength characteristics enable design improvements that reduce overall package size.

This new packaging was used to to ship memory cards and one of our ThinkPad models. With lighter packaging materials and package weight, the result was 6.7 percent less transportation CO2 emissions. We are therefore looking to expand the use of this bamboo and sugar cane fiber packaging innovation.

Over a decade ago, Lenovo began using 100% recycled and recyclable packaging material. Instead of using polystyrene packaging, we now encourage the use of molded pulp, fiber and low-density polyethylene (LDPE).

Lenovo unveiled their latest range of gizmos at CES 2022 a short while back, including the new ThinkPad Z Series of laptops featuring eco-friendly designs. The ThinkPad series is made from 75% recycled materials, the Z13 and Z16 are made from 100% recycled aluminium

just to name a couple of them.

Every brand out there is greenwashing its name...

Anyway

Apple has committed to be 100% carbon neutral in terms of its supply chain and products *by 2030*

You just need to write 1 to /sys/devices/system/cpu/intel_pstate/no_turbo , like in

sudo sh -c 'printf 1 > /sys/devices/system/cpu/intel_pstate/no_turbo'

Writing 0 re-enables turbo. Note it is not the same as the power-saving mode in Gnome settings under the Power section. This is more similar to Low-power mode in MacOS which also prevents Turbo boost.

EDIT: I was wrong to call it power-saving mode in the grandparent comment. It should be called no-turbo mode there.

This is not even close to correct. The vast majority of plastics can't even be truly recycled once. Not back into their original form, anyway. Saying Macs become "e-trash in a couple years" is similarly way way off the mark. Expected life for many Macs is a decade or more. I have one that is from 1984 that still works perfectly. After that, much of the machine is fully recyclable, and the case is 100% recyclable.

> I have one that is from 1984 that

I too own a Commodore 64 from 1983, an Atari ST, an Amiga 500 and a 286 Amstrad PC.

> Saying Macs become "e-trash in a couple years" is similarly way way off the mark

They are forced out of the market by the company upgrade policies.

What is the value of an Intel Mac now that Mx(s) are out?

I had to chime in that, if 14" vs 15.6" is not a deal breaker, P14s Gen 2 with Ryzen 5850U, 32GB RAM and integrated GPU is the most performant, silent, portable and generally capable laptop I ever had (and I've changed a lot). I got greedy and switched to a MBP 14 with M1 Pro, which is also great, but almost everything (speakers and trackpad excepted) on P14s was either on par or even better (perf, ports, weight, noi…

I hope the P14s Gen 2 is better than Gen 1, because that's the worst device I've ever owned (by a very wide margin). It constantly overheats, the CPU throttles down, and it becomes slower than my now ancient x230 ...

Are you referring to an AMD-based model? I had a Yoga Slim 7 with 4700U and P14s Gen 2 with 5850U and both were flawless in terms of performance, thermals and noise

This is a usually cited concern for so many people and I'm curious to know why because I rarely unplug my laptop, like most people I know.

This mindset is similar to what people with wired headphones think of Airpods et al. It's not an apparent benefit when you're in the bubble of thinking it's normal to have a wire going across your torso all day and hearing the thuds and bumps propagate through the wire to your ears. But when you buy a pair of wireless buds and have them for a week - you don't go back. You've discovered freedom. Likewise, with battery…

i had wireless headphones and true-wireless ones later on and i still went back. i mostly use my wired headset now and have a fiio bluetooth receiver for the times i would prefer to be more mobile.

i switch between two computers, a phone and a tablet quite a bit during the day, so having to fiddle with bluetooth settings every time i switch is more of a deal-breaker for me than some microphonic noises from the cable

I find it rather peculiar that tech folks think a plastic laptop is good build quality considering what we have from Apple and others. I wish more linux laptops had the build quality and support of macbooks. This isn't a rant from an Apple fan, this is a rant from a laptop fan. ThinkPad's aren't good laptops despite what the guy with the pocket protector says. They are flimsy and feel cheap. They still have 20th cent…

im guessing you live in a warm climate so. i don't and metal laptops are nearly always cold and sap the heat from your hands.

im not sure i would like carrying all that extra weight around either. its not like i an going out on an expedition everyday where i need my laptop to hold up in all sorts of extreme situations. ive never even dropped or broken any of my "plastic" laptops and I've been using them for a few decades now
