Why in the world if you care about battery life do you put a 12th gen Intel H-series CPU in your laptop, and not a 5th or 6th gen AMD CPU?
My Lenovo gaming laptop gets 5-6 hours with a 4th gen AMD H-series on a 60Wh battery.

Re: 99Wh Battery Linux Laptop
#52Do 10 hours of battery life "while surfing the web with Wi-Fi" really strike anyone as a strong argument these days? I'm a bit uncertain. I got 9 hours of the same out of my 2017 MacBook Air's measly battery when it was new 5 years ago . I know for a fact I don't need 14 CPU cores to get my browsing habits satisified. This laptop is trying to be a "premium business workstation" by packing a CPU that's crazy powerful…
FWIW, 10 hours of battery life with a discrete GPU enabled is fairly unprecedented. Even the 16" Macbooks that shipped with discrete GPUs would struggle to sustain the CPU and GPU for 5 hours of parallel use.
Why would anyone, these days, need a discrete GPU for surfing the web? This detail, too, just like the CPU, falls short on the fact that making actual use of its power cuts battery time down to nothing. They should just market it for what it really is: a workstation laptop with 3 hours of battery life.

#53> Configure your InfinityBook Pro 14 optionally with the NVIDIA GeForce RTX 3050 Ti and turn your lightweight business laptop into an ultra-portable gaming console! Why are so many Linux laptops NVIDIA? It know that we have the OS kernel + blob userspace option now, but it's still early days. My desktop is AMD, my laptop is NVIDIA, and the difference is night-and-day. I would honestly have an IGPU in a laptop over NV…
Because NVidia works in Linux. Intel isn't really accelerated, and AMD is buggy and doesn't do GPU compute acceleration terribly well.
Re: 99Wh Battery Linux Laptop
#54Isn't it a searing indictment of the entire Intel laptop chip lineup that a MacBook Air M1 has half the battery capacity (50Wh) while giving easily twice the battery life with as good or better performance -- and with no fans!
It's also a searing indictment of Linux. I get less than half the battery life on my Alienware AMD laptop under Linux than under Windows. I don't know what Linux is doing wrong here, but it is not energy efficient.
Why do you run Linux on Alienware hardware?
Re: 99Wh Battery Linux Laptop
#55For Dell Latitude laptops you can get 120Wh batteries (3rd party), and they also run Linux just fine. Also they're well-built and have good keyboards.
Re: 99Wh Battery Linux Laptop
#56I'm typing this on my 1 year old Tuxedo InfinityBook (S 14 Gen6, not the Pro). Now I'm definitely spoiled by the Lenovo X1 series, but I'm not happy. The hardware is a rebrand from clevo-computer.com - some minor spare parts can be had from there. The system is VERY prone to overheating, the fan is noisy. They claim the fan noise is "not annoying" which is only true in the short term. I have opened up the bottom shel…
Not having owned one personally, the questionable quality of the engineering and QC of Clevo-based laptops has what has kept me away from them. Reviews for them are almost always some shade of "this is mediocre" or "this would be nice if not for X, Y, and Z". While they still have a ways to go, I'm more hopeful for Framework since they do their own engineering, and I'm interested to see what system76 does in the self…
I've owned 2. One for 4+ years the other is 3 months old. They've been fine for me and I move them around a lot. the only issue is junk getting stuck in the fan and replacement was fairly easy. The hinged chipped when it hit the floor once (the plastic surrounding the hinge part.) Spare parts are readily available. I like Mat screens and they tend to have them.
The AMD cpu model I'm using for work is really quite good on power and fast (Ryzen 7 5700u).
Re: 99Wh Battery Linux Laptop
#57How can they claim 16h of work - I own an Asus m16 with the same CPU and a 90Wh battery and after some tweaking my Ubuntu drains 9.xWh without touching anything ... With Firefox open it already consumes 12wH - so I guess I can be happy if I can get 6h of work done with one load and this laptop here can't do much better...

Alienware? I suspect you have a dedicated graphics card? Or any other "performance"-component for that matter, which typically requires proprietary software counterpart (drivers) to run efficiently . Most vendors only ship decent Windows drivers, and the Linux counterpart (if any) is considered "good enough". I would not consider this the fault of kernel developers. Often there is basically nothing they can do. You j…
Probably an Optimus setup on the Windows side. It basically powers down the graphics card most of the time and switches to the lighter Intel graphics instead. Linux support for Optimus is poor and usually you end up having to choose either good battery life or good gaming performance.
Re: 99Wh Battery Linux Laptop
#59which is great until you see that the proc is basically a 35w monster. (peak 115watts)
https://ark.intel.com/content/www/us/en/ark/products/132228/...
45W - yes, minimum 35W but 45W much more likely in default settings.
But yes I would worry about cooling in a 14" form factor with an Intel "45W" CPU that supports a peak of 115W.

I used a dell xps with ubuntu/gnome for years that used to get me 7-10 hours of battery life as long as I turned wifi off and was working in sublime text. This was more than I got on windows, and more than my macbook got at the time
Linux is great
