Re: P53 Performance Issues - Thermal/Power Throttling?

2019-12-21, 0:06 AM

Hi nvsnow,

I'm looking forward to someone finding the relevant settings difference from the Microsoft plain installation.

 

Unfortunately, in the recent years Microsoft modified their System Builder program and I no longer can access it. I cannot renew my membership since I'm not a company, and so I don't have a listed company name. They want a listed business address that I cannot provide. So, I can't access the OEM Pre-installation kits nor their docs about the customization options.

 

My take is that companies should provide an installable customization package for their machines that can be added to a plain Windows installation. It would be useful to troubleshoot issues. Strangely, I would expect Lenovo Vantage to do those setting customization related to power, or that the power management drivers would do such customizations. It appears, from the thread listed above, that it is not the case.

 

As I already mentioned, my P52 is running 1809 from Microsoft installation media, on which I transfered most of the found Lenovo customizations not installed by Vantage. I don't have "bad" throttling behavior, but I do have "normal" thermal throttling. I kept the Lenovo installation of Windows 10 Pro 1903 in multiboot, so if you want to compare installs, I can. Just tell me precisely what you want compared and I'll do my best to compare.

Am I correct that although there is no official fix from Lenovo, all the thermal/power throttling issues of the P53 have been solved by using the methods described in this thread?

Appreciate the offer, Martin.. This all seems strange, but I'm glad that not all of these abstract theories are so not getting dismissed - we just need a couple willing ears :)

 

Other than benmarking tests, it's strange how depending on installation, one install will take on a desktop config path and another go down the laptop path. Is there something in the bios or configuration somewhere that defines how featuers get configured?

Re: P53 Performance Issues - Thermal/Power Throttling?

Hi all,

I just checked in my P52 my factory install of Windows 10 1903, and the APS function is there. I exported the drivers and tried to install APS in my Windows 10 1809 and no go. It won't install. I tried with the APS file on ThinkVantage Technologies downloads, but the file seems outdated and is not compatible. Oddly, it seems compatible with P51 and earlier.

 

That means that I can confirm my Windows 10 1809 installed from Microsoft media does not have APS, and won't install it, and that my Windows 10 1903 installed at the factory by Lenovo has it. There are settings for APS in Lenovo Vantage, like an ON-OFF switch and a sensitivity slider, on my factory 1903.

 

I created a thread in Pre-Installed Lenovo Software and Applications about the installer incompatibility. From what I read, it's installed like any program, and could be uninstalled like one. No registry messing, driver disabling and such. I await more info on that thread, and I probably will open a ticket for that.

Re: P53 Performance Issues - Thermal/Power Throttling?

2020-01-25, 19:19 PM

I think this is the most popular thread on the matter, so I'll report my findings here.

 

I have an i9/rtx4000 machine and like many found the performance to be less than thrilling after a fresh windows 10 pro install (from MS) running 1909.

 

I first noticed using hwinfo that while running cpu benchmarks, my TDP was capped at 30W! This is clearly below spec. Running graphics benchmarks, I noticed the same TDP cap, the GPU was capped at 30W as well, clearly 50W below spec!

 

I noticed that I did not have the performance slider that I had seen people talk about when clicking the battery icon.

 

I went to the downloads for my p53 and installed all four installs in the power management section:

  • Lenovo Power Manager for Windows 10
  • Lenovo Power Management Driver
  • TI Power Delivery Driver for Windows 10
  • Intel DPTF Driver for Windows 10

I restarted and the battery icon had a slider. I moved it to max. I don't have any APS service in the device manager.

 

And now, I'm happy to report the cpu now uses 50W under benches, and the GPU is up to 80W. Both now in spec and performance is great, actually really great now.

Re:P53 Performance Issues - Thermal/Power Throttling?

2020-11-10, 6:36 AM

So I've been having the issues discussed in this forum, my machine is a P53s (i7 8665U, 24GB RAM, Quadro P520) and my processor would go right down to 0.4ghz even while under load, package power never exceeded 5w on a 25w TDP processor (even when plugged in) and thermals were all under 60 deg Celsius. It was almost unusable...

 

But Hey-HO! Today I Re-installed windows and the issue is gone! Turbo-ing as expected, a much better machine. 

Upon further investigation, the new power management driver (this link is for the P53s), released today, had been installed. No problems whatsoever anymore, it runs like a dream.

So thanks Lenovo! I'm so glad I finally got it working!

 

That was quite a ride 😂

 

(EDIT: I installed vantage and updated the other drivers as well. Still no issues, working as expected. Please note though: My P53s doesn't have that 'lap mode' thingy so that wasn't a problem. Here is the driver for the P53. It's: Lenovo Settings Power Manager for Windows 10 (Version 1703 or Later) - ThinkPad )

The revision notes do not state anything related to thermal improvements.

For the benefit of all who are still struggling with this: My guess is that with the new installation of Win10, the energy setting was set to "best performance" by default (you'll find that setting by activating the energy tray icon in the bottom right and left clicking on it). Setting it on anything else prevents your machine from running at full speed.

 

The downside of this is that the CPU is never throttled down while idling. So, if anyone knows how I can keep peak performance with activated throttling at idle (the way it has always been for me with Lenovo laptops before), I'd be grateful.
