Thinkpad P53 in game switches back to integrated GPU

2019-12-13, 13:01 PM

 Hi all,

 

I'm running PUBG on my P53 with RTX 3000. Everything is good, fast and responsive, high FPS and so on, but in about 30-40 minutes on playing it switchres to integrated graphics adapter. Then after some time it goes back to dedicated. Have checked temperatures and it show normal I think, as GPU is about 78 degrees C under load and CPU is somewhere 85. One thing I have noticed is that when it happens, both CPU and GPU temperatures drop. I think it's somehow related to power management rather than temperatures. So far I have not checked other games. What is your thoughts guys?

 

P53

RTX3000

16GB RAM

Samsung SSD

CPU Power Management is ON

Nvidia Power is on Performance

Nvidia OpenGL is on Max Performance

 

Solved! See the solution

Thats' a really weird problem indeed, what happens if you disable the integrated GPU in BIOS? I could imagine that an overheated GPU might disable itself, but apparently temperatures are normal. You could try to set the Nvidia control panel to "prefer consistent performance" or "dynamic/balanced"

Thanks for your reply,

 

Yes, it's strange, as nothing unusual is happening when it does this, at least as I know. I also checked the system for some spyware/virueses, seems like nothing is sitting there. Because, first thing I started to suspect after temperature checks, maybe there is something that interrupts CPU/GPU works and then the system automatically goes to low performance / battery saving mode.

 

I have attahced some pictures from HW Monitor. Notice both CPU/GPU drop? That the point when it does switch to integrated mode.

 

 

I didn't disabled the integrated GPU yet, first I might disable CPU power management in BIOS and see what happens? But before that I'd like to see how it behaves in other games as well. I'll keep posting.

One possible explanation could be that the power supply is defective and it goes offline after a while when the system is pulling a lot of current, then it recovers. You can look into the event logs, there might be a record of power source change.

Are you sure it switches to the integrated gpu? It could be your P53 switching to a low-power state.

The reduction in cpu and gpu performance and temperatures seems consistent with that senario.

 

It seems in some situations the P53 does this, the cause frequently mentioned, is some protective action taken by the movement detection system. (No clue as to why it would do such a thing.)

See the massive topic about performance issues: https://forums.lenovo.com/t5/ThinkPad-P-and-W-Series-Mobile/P53-Performance-Issues-Thermal-Power-Throttling/td-p/4528377

A simple test would be to start the game and move your laptop or hit the table it is standing on.

 

I do not believe there is a fix available yet. (Besides a full reinstall of Windows with an image from Microsoft.)

@Farway I believe you are talking about the APS (Active Protection System) issue. For that issue, AFAIK the system currently doesn't automatically recover from the degraded performance state once it goes into it. Since the OP says for him the system does recover, I would think this is unrelated. Regardless, there is a workaround for that issue that doesn't require reinstallation which I posted in the same thread you linked to. The steps are summed up by SvenDJ here:

Thank you guys for your support!

 

I haven't been paying much attention to power supply until ThinkpadIL mentioned about it. I have unplugged all other devices from outlet, double checked the power supply of the laptop itself for good connection. Right now I can't be sure of course, must be monitored in long term but I've played about 10 matches and so far without single frame drop. 

 

One thing worth mentioning is that before this issue started I was playing in BIOS with CPU Power Management. I've disabled it to check if CPU buzz/whine thing will go away. Not a big deal but anyway, was wondering.... After several restarts I've noticed a message like "The power supply wattage is low, please use the power supply shipped with laptop....". I thought it was related to the setting I changed and switched it to the original value, not realizing that it might be the power supply causing this message to appear.

 

Seems like it needs a lot of power when under heavy load and a single drop in power line will couse power management to trigger low power mode.

 

Fingers crossed, maybe that's it. I'll keep posting.

Could be that the cable wasn't making a good connection with the charging port in the computer.

 

Worth checking whether the coil whine comes from the computer or from the power supply. In a P53 that I received for my client, there is a very bad coil whine and it's the power supply that's making it. I'm replacing that supply under warranty.
