Why? It's screen would flicker due to PWM. This is noted on your model at https://www.notebookcheck.net/Lenovo-Legion-Y720-7700HQ-Full-HD-GTX-1060-Laptop-Review.218710.0.html
It appears that the Asus does this as well. https://www.notebookcheck.net/Asus-ROG-GL503VD-DB74-7700HQ-GTX-1050-Laptop-Review.259452.0.html
This means these two are nearly identical and for now the 1060 gets the nod due to superior GPU performance.
As to weight I used such for work and didn't notice any troubles.
BUT for college users I worry about daily transport as they tend to schlep the laptop in backpacks and the laptops usually last about 2 years.
I am trying to choose between a Lenovo Legion Y720 80VR00CJUS and Asus ROG Strix GL503VM-DB74 Hero Edition. The exact specs are given in the following links:
1) Lenovo - Click on View Current Models
2) Asus - Details at the bottom of the page
My primary use is not gaming, but gaming laptops are suitable for my work. My application areas include machine learning (especially training Conv. neural network), simulation, 3d design, robotics and computer vision. This also means that I need to be able to use Ubuntu OS on dual boot without any serious issues.
I am looking for opinions/ advice from owners and users of these machines regarding the following:
1) Reliability/ Failure Rate - A 2009 report says that Asus has the lowest failure rate. I have owned a Lenovo y510p since 2014 and I was able to use it for around three years. Then I owned a Lenovo y700 for more than an year until I spilled water on it. What are your experiences with Asus?
2) Ubuntu OS - The last time I purchased a laptop, I picked Lenovo against Asus because of the reports that said GPU and touchpad of Asus laptops doesn't work well in Linux. I have also heard that those issues have been resolved in the later models. Kindly let me know if anyone can provide any inputs.
3) Does y720 have a faster SSHD/HDD compared to that of GL503VM? I saw a report which said that the SSHD on Asus machine is slower than that of y520 (I am assuming Y720 will have a faster one compared to Y520). I am not concerned about the boot up since both machines also have SSDs. I am interested in the time required for copying operations.
4) How many hours of battery life are you getting with moderate to heavy use?
5) I have never owned a laptop that weighs more than 6 lbs and Y720 weighs 7.05 lbs. Is it noticeably difficult to carry around on a regular basis?
