The most durable refurb/after leasing HPs with i5/i7 n-gen?

How long are HPs supposed to last (built after 2010) . I am interested in built quality - if bough after leasing from corporation - so at least 3 years old - how long would it work on average? I know sometimes capacitors on mobo dies. Hdd of course. But generally electronics with stiff casing (business laptops) should last at least 6 years ?

Any suggestions what model of refurbished HPs should I look for (which i5/i7 generation is the most durable?

 

Look for Sandy bridge or newer (that is the first 4-numbered i5/i7 processors).
In the Elitebook range those would be 14" 8460p, 15" 8560p/w etc. Comparable Lenovo range would be t420, t520.

This is from performance view: first gen iCores were not that good compared to second and later generations.

In physical durability view: choose an Elitebook. When you have one in your hands, you'll know why. They are not the same as consumer products.

Probook line is a hit-and-miss, some of them are pretty good while others seem to be rebadged Pavilions.

I recently ditched a t420 for 8460p as my work laptop. I use whatever I get my hands on when some customers lease ends, sometimes there can be gems along the way.

What size and other requirements you have?

 

I need no PWM display or any good for eyes - so I heard 8740w or 8540w has dreamcolor panel with no PWM. I need cpu and GPU for Matlab and similiar calculations but on amateur level. Also I d like to connect to my 3x 3,5 jack creative 5.1 audio.
I do not play games. Just mutlimedia + work.
I need desktop replacement i do not move laptop around to much - it sits on a desk 90% of time.

 

My "desktop" at home is HP 8560w that sits in the advanced docking station. Connected to two 24" displays and external kb/mouse. I've replaced optical drive with hdd caddy, so I have internal ssd and hdd. Bluray drive is in the docking station.

Computer itself is fairly good, i7 2630QM, 16GB ram and Quadro 2000 gpu. In addition I have two 4TB external usb3 drives connected.

I dont see any need to replace this one anytime soon but if I did, it would probably be 8760w or 8770w i7 because they have one more internal hdd slot and their gpu is upgradeable with some effort.... and it would sit right in my docking station.

For best upgradeability look for i7 models because they usually have 4 sodimm slots, giving you cheap-ish 16GB or full 32GB option. i5's support only two sodimms.
