CPU working on low frequencies while the battery unplugged

HP Recommended
Elitebook 850 G5
Microsoft Windows 10 (64-bit)

Hello,

 

I have given my notebook to the service for the replacement of the battery. Because I noticed the battery is like a bubble when I opened the bottom cover for cleaning the dust. Then I got back the notebook from the service to able to continue using it, when the new battery arrives they will inform me.

 

I'm using the notebook with AC power right now, the problem is the CPU(I7-8550u) working in 1.1 to 1.8Ghz range. I tried the reinstall Intell drivers, I checked the Power Options, everything looks fine. As an addition, the charging led is blinking with orange color. 

 

I couldn't solve this situation, the reason probably the unplugged battery. I think normally the unplugged battery shouldn't be a problem for the computer. Currently, working with the notebook is kind of hard.

 

I was wondering if this situation is normal and why this is happening? Is there any technical reason? Some example; when I was using Elitebook 8460p, the battery unplugging wasn't a problem.

 

Lastly, English isn't my native language, if I made any mistake, I'm sorry about it.

 

Thanks!

The first thing i would try to do is to run HP Image Assistant and update the BIOS and ALL drivers it suggests. The laptop should work fine without the battery while plugged in to a/c current

 

and your english is fine. you explained your need well

I work for HP. However, all opinions and comments are my own.

I tried to fix this problem by Updating all drivers via HP Image Assistant. I did run the HP Image Assistant, then I updated all suggestions. After the driver updates, I opened the Update BIOS page within BIOS, but I learned my current BIOS version is the latest one. 

 

My current BIOS version 01.14.01 Rev.A, I also checked from this HP EliteBook 850 G5 Notebook PC Software and Driver Downloads | HP® Customer Support driver page. I thought If I roll back to an older version of the BIOS, this is may resolve this issue. I tried to roll back the BIOS, but I couldn't. It showing "update denied by system policy" message when I try to roll back the version. Firstly I exported all settings of the BIOS to a USB driver, then I returned to Factory Defaults to solve the rollback problem. Anyway, all of my attempts were unsuccessful. 

 

I found a program which is named ThrottleStop, It shows "EDP Other" in the limitations tab. I don't know what is the meaning of that. 

 

I'm checking new drivers from Windows Update and HP Support Assitant. And sometimes I'm using the website to check manually.

 

Thank you for your interest, I will wait for a new battery. I found similar topics for other brands. I think there has a limitation to using the notebook via an unplugged battery.
