Did you check business-grade laptops ?
Lenovo has Thinkpad(T, P series etc) and Dell has Latitude, Precision (and Vostro too, but dont bother) and most IT companies use these in their work environment. You being in the IT business, hope you know better.
I bought Thinkpad Edge-430 in 2013, sold it in May, 2020. Never serviced, I even get 1hr battery usage at the time of selling.
My usage was browsing (my open tabs are more than 40), lots of overnight downloading movies (it has dolby gimmicks and it works fine too) and ran Ubuntu on Virtual box for programming stuff. Gaming was max CS. I rarely shut it down, always on sleep.
I upgraded to Dell Precision 3540 now.
Sometimes, I miss my thinkpad for its matte finish, screen and its keyboard/track pad. They are the best. PERIOD.
My point is business grade laptops have better build quality and last longer
I see my friend's Inspirons and HPs failing, it can be display/ports not working/ I even saw an overheating issue. Dont know about Asus or Acer
If, you can source the laptop from US, then, at 50K, you can get a great laptop.
I, actually missed a great discounted deal on "Lenovo Thinkbook", so "settled" for Precision
Few pointers-
1. Gfx card is really unnecessary if you are not into atleast moderate gaming/video editing stuff.
2. Check available upgrade ports for RAM and SSD (NVMe type). No SATA
3. Better to go for HDD version and upgrade to SSD after few months. Company equipped SSDs are very costly. Same with RAM chips.
