P53 Problems

2019-09-25, 7:20 AM

So I already sent in a sorrt ticket, I have lots of major issues, I hope some of you guys have some solutions due to lenvo not really helping (I cant get a replacement at the current time due to school / work), I have the i9 model.

 

 

Problem #1:
The GPU (RTX Quadro 4000) works as intended for 30-60 mins but then almost randomly it seems to go into a state of low power/just very slow (Locked at 300 mhz), refreshing drivers does not fix the only way to fix is to restart the machine. I have tired may different versions of the drivers, no effect. Running the machine in detected graphics only, no effect. Manually controlling the clock speed, no effect. Not having any processes running on the gpu or having the gpu maxed out the hole time of the machine running, no effect. There is no rime or reason to it, hinders my workflow greatly. This issue was present on delivery of machine.

 

Problem #2:
Chassis is very bent and does not sit flat. Screws can be loss-end and retightend with the chassis flat but after a day it will warp its self back to the 1-2 degree difference in the feet. Putting it in my bag is a death wish for the bend so I just case carry it now. present on delivery.

 

(Did not include in ticket) Problem #3:

Something is really borked with the cooling software, This issue has been talked about in other threads (running -130mv helps but it still hinders workflow when the cpu bounces form 0.8 ghz to 4.8 ghz when all the cores are stressed instead of a constant throttle it like to do that werid thing where it over compendates and then under compasates itself (is even worst without undervolting))

 

(Did not include in ticket) Problem #4:

Horrble GPU coil wind, like really really load, 3 times loader then my open case desktop qutro, makes working on cad in class annything due to the horrble screaming

 

Any help would be greatly aprreated

Can you please post a picture of the warped chassis?

I've contacted Lenovo support about this and they've informed me the CPU issues is a known problem. Not sure how that translates into a solution, but I'm having exactly the same issues with it bouncing around in speed performance. It makes it almost unusable in the music software I'm trying to run on it. Let me know if you get any feedback from Lenovo about this issue. I really want to like the machine, but My 6 year old Xeon runs better for me than this one at this point.

I noticed the same thing with my P53, it does not sit flat on the table. VERY annoying everytime I lift my wrist it wobbles.

How old is the system?

I had a similar thread before about the gpu clocks and coil whine here :

https://forums.lenovo.com/t5/ThinkPad-P-and-W-Series-Mobile/Thinkpad-P53-Gpu-clocks-problem-and-coil-whine/m-p/4537535

 

My solution was to simply reinstall the stock windows 10 install that lenovo provided. It seems like their power plans screws something up and thermal throttles the gpu. Since I done that I had no gpu problems under sustain load for long hours.

 

I also have coil whine with the rtx 4000 and I think its gonna be a common issue on these devices since they pack such a powerfull gpu in a relatively small chassis.

 

Let me know if Lenovo resolves your problem cause I am curious and planning to set a ticket myself in regards of coil whine, as I find it unacceptrable on hardware like this.

I've been setting up my P53 with the XEON processor + the RTX5000 GPU this evening. So far I do not hear any coil whine when I use the GPU, the OLED screen is simply amazing for color accuracy (I had the factory X-Rite calibration performed) and brightness. I know that the other 4k UHD screen is a bit brighter, but the contrast level of the OLED panel puts a backlit LCD panel to shame. The only thing that I can see that might bother a critical user is that you can see a fine mesh grid for the touch capability very faintly on bright continuous areas, but you almost have to put your face on the glass to see it. I'm still working through my settings (and it will take another day or so), but I'm very pleased so far. BTW, the memory SODIMMS are first installed under the keyboard at the factory (a question that I posed several weeks ago) so adding additional memory is under the back panel where it is readily accessible.

I'm curious, how's the brightness on that OLED and the battery life?

 

I know the nits measurements on the sales page but not sure how that translates to real-world eyeballs. Typically I don't "outside" much but in the summer months, it would be a nice option and my current 4-year-old gaming Acer has about 250 nits,

not bright enough. I was also looking at the reg. 4k as I really would like the calibration.

The spec says 400, but the Samsung panel spec says as high as 600 nits to 450 nits. I keep the brightness setting 2 steps down from max because it is too bright for most of what I do. The OLED panel + the Intel 630 GPU yields between 4.5 - 5+ hours using IE11, Outlook, Netflix, etc. I have the NVIDIA RTX 5000 GPU as well. If I use that, then the battery life is somewhere between 3.5-4 hours using the same scenarios.The calibration spec that I use is DCI-P3 which yields stunning renditions on photos and streaming content. Of course, the system supports Dobly Vision as well as HDR. I don't use this system outside, but I do use it in my sun room without any problem. The AR/AS coating seems to mitigate most of the bright reflections. Of course, the fact that this is a glossy screen rather than a matt screen makes everything sharp.

Thanks very much for that!
