    Hi all. I have a 2014 W540 on which I mainly use cad software (TurboCad 2018) and I was thinking of replacing it with a P52. The W540 runs an i7 4800MQ processor, has an SSD, 16Gb ram and runs Windows 10 Pro. It hasn't been the most reliable machine - early bios issues, stuttering issues, audio problems and a failed keyboard (the latter fixed under warranty), failed SSD, failed battery to name a few. It should have plenty of horsepower but it does seem to struggle with some of my large cad files (my plans are 2d, minimal rendering but the actual drawings cover very large areas, hundreds of layers and upward of 60 different views / paper spaces). On the big files it often hangs and there are long delays especially when snapping to points on a drawing. It may well be that it's just the nature of the drawings I'm doing. I tried the same drawings on my partners old E520 and it was much slower so perhaps it's just down to the processor and ram. I often have multiple applications open while drawing - Google Earth, Chrome, Adobe Acrobat, TurboCad, Dropbox.

    Apparently the basic functionality of Turbocad is single threaded and 16gb ram is recommended, along with an SSD. So my question is, do you think I would notice any significant increase in performance if I went to a P52 (currently thinking either the i7 - 8750H or i7 - 8850H versions, both with 16gb ram).


    Recently it has also started displaying it's unreliable characteristics again - not starting properly, having to reinstall several programs, blank screens etc. Might just be a Win 10 problem but perhaps more - however I draw plans for a living so need a fast laptop with minimal down time sorting out problems.

    Advice gratefully received!

    Forgot to add, the fan in the W540 does seem to be working overtime on plenty of occasions.

    I think it would be worth it, 5 years is a pretty big gap for computing power. Some companies do have allowance to purchase computer so if you got that then that'd be a no brainer.

    I'm a freelancer so it'll be my money! Was interested in comparing the clock speed of the W540 processor compared to the ones available in the P52 and in theory there isn't a huge difference. In reality I'm hoping that the difference would be more noticeable.

    Now I'm not a tech expert but that is interesting, especially the single thread and CPU mark. So although the clock speed of the 4800 is higher it seems like it is outperformed by quite a bit.

    Based on my horrible experience with the P51 my humble advice would be to forgo Lenovo entirely and buy an HP ZBook 15 G5 or 17 G5 at the give away prices on eBay right now. Based on reliability, upgradability, ease of access to internal components, and performance HP may have the best workstations on the market.

    I must say I didn't have the best of luck with my W540 at first but surely they would have sorted out any potential glitches on the P series by now? I know some people won't have any issues, others unfortunately will - irrespective of the make. Can any P series owners comment on this? I've had an HP before but that was ages ago and the ZBook was on my list but to get the same spec as the P52 with a 3 year warranty I'm looking at paying quite a bit more - but perhaps there's a good reason for that! I'm wary of eBay - the majority of similar specced G5's seem to be either used, refurbished with short shop rather than manufacturers warranties or much more money than a new Lenovo. Hmmmmmmmmmmm.

    The consensus on the Lenovo workstation forum is that most of the issues seem to have been worked out for the P52 (a year after release). If the P52 starts having random blue screens, though, then that is an issue. Lenovo will try to leave you with a dud machine, as they tried to do to me and other P51 users. I might add that the P52 has poor cooling so expect some throttling. There is a YouTube video on this where even repasting doesn't work because the single heatpipe is saturated already.

    I would be remiss if I didn't add that I loved the P51 until I started having problems: HP wasn't my first choice.

    Oh quite so: never buy any of these computers without the manufacturer's warranty. If the laptop has an original warranty then it is safe to buy it from anywhere. You can ask sellers for the serial number which you can verify on the manufacturer website. It will tell you how many years are left and whether the machine was serviced. It is kind of weird that an HP G5 model wouldn't have the manufacturer's warranty though: all of them should have 3 years standard.

    Thanks for the feedback. I'll continue my research.
