CPU Core Speed stuck at 0.80GHz Latitude e7440
Hello every one,
I try the core speed of my cpu won't exceed 0.78 Ghz. I've updated the bios to A25 check that's not the issue. Power options in the windows settings are high performance so that's not the issue either.
The core speed is the same when the PC is idle, and when I send it through stress test.
My PC specs
Intec cor i5 4310u
8Go Ram
256 SSD
windows 10
Thank you for helping

Does the system recognize the AC adapter, or does it show "unknown"? F2 at powerup to check.

Hi All,
My Latitude E7440 has the same issue -> CPU is extremely slow under all activity and Windows Task Manager shows speed as 0.78Ghz
Change power plan from Balanced to High performance does not help.
Bios A25
Windows 10x64, CPU i7-4600U, RAM 8 Gb, SSD
Dell AC adapter is recognized, 130 watt - I've tried a few AC adapters and dock stations taken from colleges - the same issue :(
Any help ?

I have the same issue with my latitude e7440 core i7 4600u , its stuck at 798mhz clock speed at full throttle, has anyone fixed this issue?
Currently on a23 was going to update to a25 but waiting until i get a new battery as mines dead and i dont trust the power grid. Specs are as follows
Core i7 4600u
8gb ram 1600mhz ( 1 stick )
Windows 10 pro
128gb ssd
My idea was to flash bios to A01, and work up from there all the way to A25, that has fixed some peoples issues, i havent tried it yet but maybe someone here can, and can verify

Your laptop had a voltage problem on the battery.
The system blocked the core at 0,8 mHz for security.
But he never come back to initial.
to solve the problem, remove the battery.
If not result, install Throttlestop and disable the BD PROCHOT setting.

Hey there! It´s been a while since this incident, but it turns out I got a refurbished Dell E7440 recently, same model as the one in the post, and I have the exact same problem. The place where I bought it claims that it is normal on this model to work that way, is that right?
Thanks!

You should try to install the software "Dell Power Manager".
In the "Thermal Management" tab, you need to select option "Optimized".
-----
Your issue might be that you computer is currently locked in the mode "Quiet" or "Cool" which can cause your CPU to be limited at 0.8GHz

Hello guys. Your assistance would be much appreciated. I have an Alienware R17 i7-4800MQ 2.70 GHz.
I am having the same issue, my CPU performance stucks at 0.78 Ghz. I did follow your advice: unplugged my battery charger and noticed straight away, that CPU increased and I could see the difference in my performance. I also restarted my computer with 16% of the battery life (unplugged). After windows loaded up, I've plugged it back in and CPU still went back to 0.78Ghz.
As a result I now have 0% of battery plugged in, and it's not charging. I did try to unplug, take the battery away and hold power button for 20 seconds. My battery is still not charging. Also I have tried to run Windows without my battery, still same 0.78 Ghz… :(
