Re: IdeaPad Z710 Intel Turbo Boost Technology problem

2014-06-17, 21:23 PM

Do you agree with me this is a BIOS'S PROBLEM?

 

Answer: NO. It's more in the software side than in the firmware side.

 

 

I have experience with laptops for 4 years and this kind of problem happen is bios.

 

Comment: This occurs in laptops in the past when turbo-boost technology was newly introduced.

You right.

 

The only problem I saw on the past was, to get turbo boost on, we have to go into the bios and put the "turbo boost option" to enable.

 

I hope the Lenovo or Intel get this sorted for us.

If you are using the Windows High Performance Profile and the Minimum and Maximum Processor States are set to 100%, your CPU should have access to full turbo boost.  If there is no turbo boost, that's a problem with the bios.

 

The bios needs to set the maximum multiplier register to the correct value when it does the hand off to Windows.  If the Windows Power Options are set up correctly and ThrottleStop can correct this problem, that means the CPU is not being setup correctly by the bios.

 

Lenovo just released an updated bios for the Z510 because of its getting stuck at 0.77 GHz problem.  Now it is time to work on an updated bios for the Z710.

Most of them don't have that option existing. So it's a delimma to come up with an update.

IdeaPad Z710 Intel Turbo Boost Technology problem

2014-06-18, 8:13 AM

Turbo Boost is not enabled without Battery plugged in and on AC only

 

 

Answer by Lenovo

It's by design - you have part of the power delivery system removed. A higher wattage power adapter may eliminate this behavior.

Hi,

 

Thank you guys for these information.

Usually I use the laptop without the battery. (I always use the battery only on the weekend).

 

I will test the turbo boost with battery and I let you know.

 

Thank you again.

Hi,

 

I have tested Z710 with battery and the turbo boost works normally. Without any program or extra click.

I haven't tested the new BIOS yet, tonight I will test it to see how the new BIOS will work and I let you know.

 

Thank again.

Hi all,

 

Thank you again for the support.

I have installed the new BIOS but the turbo boost only works with battery plugged.

 

I totally agreed with FESMS''s answer:

 

"It's by design - you have part of the power delivery system removed. A higher wattage power adapter may eliminate this behavior."

 

The most important for me is "the turbo boost works 100%". To keep the battery working ok I have installed the Lenovo Energy Management.

Sorted :)

 

Once again thank you!

Re: IdeaPad Z710 Intel Turbo Boost Technology problem

Thanks to those who suggested ThrottleStop. I recently upgraded my cpu from an i5-4210m to an i7-4702mq and was disappointed to see that the benchmarks I was running were reporting lower scores based on the 2.2ghz speed rather than the 3.2ghz turbo speed. I have no option in my BIOS to enable turbo boost, even though I am running the newest version of the BIOS for the Lenovo IdeaPad Z710. I am running Windows 10 Home. Both my old CPU and the new one run at the same wattage. I also recently did a Win8.1 to Win10 upgrade on this system before switching out the CPU, unsure if that had anything to with it...

 

By configuring ThrottleStop, I am now seeing it turbo up to 3.2 GHz during benchmarks and other things. But it's shocking (at least to me) that there is nowhere else to enable the turbo in either the BIOS or Windows.
