"-Remove TDPL method for DPT", elaborate please?

I can't find the TDP limit in advanced power option anymore, so i traced back the Intel dynamic thermal platform thing and the BIOS to see if anything is the cause, and i came across this note "-Remove TDPL method for DPT" in the 1.3.6 BIOS (i had 1.2.15) and i'm 95% sure this refers to that particular setting.

Can someone ascertain that this is indeed the cause??, if it is, why did Dell remove it??, was it causing a certain issue??, did it not work??

note: i have the i7 6700HQ

 

Did you find an answer to this?

I cannot find TDP settings any more in power options. You can turn it on with a registry edit though since the entry there. But it makes no difference whatever options are set to. CPU always consumes 40W at full speed.

This greatly affected my idle battery time. Previously I was at 12W with TDP set to low, now it is about 17W.

I am not sure if moving to 1.2.15 BIOS a month ago or Win 10 Anniversary install made the difference. Previously I was on 1.2.3 when all was fine.

Also Intel Thermal Framework driver 8.2 installs but is disabled. Only 8.1 works without error.

I will install older 1.2.3 and see.

 

I highly recommend to go to bios 1.3.6 at least. lower bioses maybe cause problems with the internal dc cable.

 

I have no problem with 1.2.3 for almost a year. Why try something else?

Any BIOS upgrade risk bricking the laptop, so I need to find out first if this is not software related.

 

Al bios-es since 1.3.6 are good now without any risks of bricking unless the bios update goes wrong.

The old bioses could cause a problem causing a slightly burned DC-in cable which you can see if you open the maintenance panel on the bottom and check the cables in there.

 

Now, you can see a new service called ESIF upper limit framework that manages cTDP levels w/o user intervention.

 

There is always the risk that you can brick the computer on a BIOS install whether the BIOS is good or not. You can do it once, twice, 10 times, but as the saying goes "Grasshopper jumps thrice". The more you do it, the more you are likely to get hit.

I don't have any burnt cables. Could you elaborate some more on this "burnt-cable" issue? What is it? Why does it happen?

Thanks Vasudev. I am aware of this.

But like I said, before we could modify the Power Plan and it would adhere to TDP settings there. This was at least a way for us to know that Intel DTPF was working. How can we ascertain if it is working fine now? If you read above, I have problems with higher consumption.

Given that I have changes:
1) BIOS from 1.2.3 to 1.2.15
2) OS Change from Win10 to Win10 Anniversary
3) Intel DTPF version

I want to eliminate software aspect before I go ahead with a BIOS downgrade.

 

Goto services.msc, set ESIF Framework to manual and most probably, that higher power consumption can be reduced.

 

I really do not recommend to go to a lower bios anymore. 1.3.6 is the next real stable bios.
