HP 450 G8 (i5-1135G7) starts lagging and becomes extremely slow on battery power

It looks like your images were removed so I cannot help you with your settings. If you need help with ThrottleStop, use the TechPowerUp ThrottleStop forum. There is a link to this forum in the ThrottleStop download. 

When Speed Shift is properly enabled, you should see SST in green on the main ThrottleStop screen. This needs to be enabled so Windows can properly control the CPU speed.

Thank you so much, brother. I am so sorry if the images were removed. I've not uploaded two images to my own google drive and removed the restricted mode for you so you can view them now.

The first image shows the settings where I switched on the MMIO lockbox and speed shift in the TPL window. Then on the main window, I enabled Speed Shift EPP.

I just need guidance after this. Do I need to click "Turn On"? Just this and the issue will resolve? Thank you so much

Here are the images:

When Speed Shift is enabled, you do not need to press the Turn On button. I usually press this button but it does not matter. 

You usually do not need to check the Speed Shift EPP box on the main screen. As long as Speed Shift is enabled, Windows can manage the EPP variable. Look in the FIVR window to see what Speed Shift EPP value the CPU is using. 

Your screenshot shows that Disable Turbo is checked. This reduces CPU performance. If you want the full performance you paid for, do not check Disable Turbo. 

With Speed Shift enabled and when ThrottleStop is setup correctly, does this resolve the problem you were having?

OMG. You have become my first love now 🙂

The issue seems to be resolved now. What you asked "Look in the FIVR window to see what Speed Shift EPP value the CPU is using. ", the value there is 128 (do I need to change it or something?)

Now, my last question (you've already helped me so much). Do I need to run throttlestop every time windows starts? Thank you so much. You are a genius 🙂

You can add ThrottleStop to your Windows start up sequence using the Task Scheduler.  Here is a guide.

An EPP value of 128 is fine. When your computer is plugged in, you can use ThrottleStop to access the Windows High Performance power plan. This tells your CPU to run at full speed even when lightly loaded. Some people prefer doing this so there is less latency. It is best to switch back to the Balanced power plan when running on battery power. 

It is good to hear that your laptop is running much better. I am not sure why some manufacturers were afraid to enable Speed Shift Technology. Intel specifically designed this CPU control method for laptops.

Hello Unclewebb and thank you for your awesome software!

Kevin, it seems that the user Shuaibikram had changed CPU values in the UEFI options inadvertently (most probably the Runtime Power Management option -default is ENABLED), because I've worked with the G8 probooks (450,470,650) and they always have SpeedShift enabled. BTW, I've discovered that if you use powercfg to show the HIDDEN power options PERFEPP and PERFEPP1:

Power Setting GUID: 36687f9e-e3a5-4dbf-b1dc-15eb381c6863 (Processor energy performance preference policy)
GUID Alias: PERFEPP
Minimum Possible Setting: 0x00000000
Maximum Possible Setting: 0x00000064
Possible Settings increment: 0x00000001
Possible Settings units: %
Current AC Power Setting Index: 0x00000021
Current DC Power Setting Index: 0x00000032

Power Setting GUID: 36687f9e-e3a5-4dbf-b1dc-15eb381c6864 (Processor energy performance preference policy for Processor Power Efficiency Class 1)
GUID Alias: PERFEPP1
Minimum Possible Setting: 0x00000000
Maximum Possible Setting: 0x00000064
Possible Settings increment: 0x00000001
Possible Settings units: %
Current AC Power Setting Index: 0x00000021
Current DC Power Setting Index: 0x00000032

....and change them to 100% in your power plans (which is a SpeedShift value of 255)

....you can then use Throttlestop's main window to change the SpeedShift value to whatever you like, and Windows no longer tries to change it. That way, you can change the SpeedShift value "on the fly" without having to switch power plans.
