Thinkpad P52 vs ZBook 15 G5 vs Precision 7530

03 Mar 2019

This is my experience working on the best mobile workstation of 2019 with specs matching Thinkpad P52 and ZBook 15 G5.

I wanted at least 15inch display processor i7-8750H, reasonable graphics P1000, at least max 64GB RAM, RJ45, trackpoint, physical resilience. I first decided to buy ZBook 15 G5 over Thinkpad P52 and Precision 7530, but ended up using Thinkpad P52.

I also shortly considered a wild card 14inch Latitude 5491 as it had attractive price, but it missed too many of the requirements (poor cooling, low max ram, poor physical resilience, low graphics).

Specs

Experience

I bought ZBook 15 G5, but ended up replacing it with Thinkpad P52.

  • Charging port is too thin and probably will be damaged soon
  • Page Up, Page Down keys are not as conveniently placed as on Thinkpads
  • Home, End, Insert keys were replaced by useless keys Desktop, Call, Hang Up contrary to Thinkpad
  • Home, End moved to the top right
  • Insert key completely removed!
  • Up and Down keys are stupidly thin!
  • While the notebook should have passed MIL tests it doesnt really seem resilient as Thinkpad
  • Without repaste the performance on Cinebench R15 drops to 1030 the same as on Thinkpad P52
  • Linux (Ubuntu) runs ok, except for trackpoint which doesn’t work on Ubuntu 18.04
  • Overall, I think I will be replacing the notebook with P52

Experience

Thinkpad P52 is my main machine now.

Update 2019-05-07

So far minor issues with P52

  • Refuses to charge sometimes even with 170W charger. Seems to be getting worse.
    • Battery issues were resolved during on-site support from Lenovo. Most probable cause was faulty power source, but the mainboard was fully removed during inspection (for no reason), so I cannot confirm the issue wasn’t incorrectly attached connector or needed hard reset.
  • Display cover seems too easy to bend
  • LTE modem supported but not yet installed in my version
  • I will be ordering LTE modem and will attempt to install it either with on-site support or manually.
Update 2019-11-02
  • Linux dmesg messages about “temperature above threshold” are gone after repaste. The service guy haven’t returned some of the screws.
  • I had to disassemble the whole notebook due to pouring almond butter all over it - faulty jar in my backpack.
  • I posted about thermals P52 vs P53 here.
Update 2020-04-26
  • Message “temperature above threshold” returned into dmesg log, so it seem that the improvement after repaste is only temporary.
  • I posted a video comparison of P52 vs G5.
