did you try to edit your battery plan and increase the 'processor power management'?
go to "minimum processor state and change the "on battery" option to 70% for example.
im not sure it will work but you can try it 🙂
That would be nice, an ETA or more info. I am about to return this laptop the last day of the Return window and look for something else but I got it for $900 which is a pretty good deal for the i5-8300 / 16GB RAM / geforce 1600 combo 😞
Sorry to say but it has been almost two years, its 2020 and your team has not done much interms of fixing this issue. My almost two thousand dollar computer cant keep up at all with a intel celeron laptop, Its sad. This was a computer that i bought for school as well as personal use and its absolutely useless 90% of the time on battery. It is revolting that a company has singled out so many users of Dell products in the way that you have. We all have bought your product expecting quality. This is also a premium product too, two thousand dollars i spent on this computer, its not a little sum of money. I am aboslutey dissapointed with the actions or the lack there of taken by dell in this issue.
I hope you understand this frustration.
This CPU throttling on battery power is appearing in the last 6 months on Dell Latitude E55xx and E74xx business laptops also. Prior to 6 months ago, the issue didn't occur for the few dozen laptop machines here.
The 2.3 Ghz i5 CPU drops to 0.39 Ghz within a second of the dell supplied power cable being disconnected, and switching to run on battery power.
Same occurs under a new windows 10 install (1803, 1809) or under Ubuntu Linux, latest bios firmmware and dell support updates, and intel power management.
There is only the internal Intel graphics card, so it's not likely to be tied to overheating sensors.
This needs a fix or workaround or we'll have to drop Dell as a supplier of laptops. We didn't want to buy bad performance desktops with a UPS.
We require the machines to be usable while away from the mains plug..
Having the same problem... G7, the CPU is always around 800 Megahertz and 1.2 Gigahertz. making it useless when unplugged. Really hoping for a fix quickly, I use engineering software which needs a lot of resources... which is why i bought this laptop, but i find it super annoying having to pull out the giant charging brick every time i need to move an object on a 3D print file.. its either that, or waiting 20 minutes for it to slice... when its done on 10 seconds with the power brick.
Dell Support stated that they are still looking for a proper BIOS for the G5 and G7 laptops with this thermal throttling problem even after the 1/22/19 BIOS update version 1.8.0.
Dell Support told me they are working on a fix still and it is currently "working as intended" ....... I am going to call every other day and just eventually demand a replacement from a manager. I would do the same if I were every one of you, this is totally unacceptable that a laptop that costs $1,100 cannot even be used unplugged. Ridiculous.
"Working as intended" but still working on a fix...
I'm getting the same vibe from support. They try to fix it but there's nothing wrong with it. I'm almost as furious as you. Stopped calling since they told me not to call anymore. I'm fine with my xps 13 gradually throttling down when it heats up but this instant 0,89ghz is ridiculous.
are you saying that setting a 30 turbo multiplier in throttlestop lets you not throttle to <1GHz on battery when making no other changes?
Will look into that EC workaround as well, appreciate the response.
This is not part of this issue. This issue doesn't have anything to do with the power adapter since the issue is only when the laptop is running on batteries. It runs fine when plugged in (no CPU throttling). Glad you figured out your power supply issue though.
This power connector post has absolutely nothing to do with what we are dealing with here, brand new laptops out of the box that cannot be used on battery. I would like to request information about returning this defective laptop to Dell.
I observed something on Linux with my G5, for whoever cares.
Because I am on Linux and Nvidia has awful Linux drivers (I knew this buying the machine), you have to switch your entire system to the dedicated GPU or the entire system to the iGPU. You can't have it be where it only uses the dedicated GPU for games to save power.
Now what I noticed is... when on battery and I have my dedicated GPU active, the CPU isn't as horrendously throttled and actually quite fast. It doesn't seem to reach the full capacity (8750H, it reaches like 2.5 GHz vs 800 MHz when power throttled)
Of course, this also means your battery life tanks.
I get the feeling this is just a really horrendously implemented power "saving" mechanic that's supposed to turn off when the dGPU kicks on.
Anybody tried this with the new 1.9 BIOS update? I couldn't get it to install on my system because ??
I'm also gonna try experimenting with turning the dGPU on but just barely with Vulkan to see if that lifts the CPU throttle but doesn't make the dGPU eat my battery.
Sorry, I am not a windows user so I thought that the 'best performance' mode is somehow related to the battery. But if you're talking about governors, then yes, this is definitely something I am aware of. I tried it without any luck. Not only I was changing governors but I was also changing scaling drivers. I tried with pstate driver as well as acpi one (with every possible governor for each driver). Nothing helps - once the battery is full, the CPU stucks.
I recently discovered that the dedicated Nvidia GPU is powered on all the time.
I've followed the procedure described at Arch Wiki. Installing bbswitch and putting:
options bbswitch load_state=0 unload_state=1
into /etc/modprobe.d/bbswitch.conf will disable the dedicated GPU (you have to set PMMethod=bbswitch in /etc/bumblebee/bumblebee.conf). Unfortunately, it cannot be enabled without disabling the bbswitch first as power management is somehow broken (source:https://forum.manjaro.org/t/bbswitch-non-functional-on-dell-inspiron-g5/72032 and https://bbs.archlinux.org/viewtopic.php?id=238389).
This will at least increase battery life a bit and enables a user to actually "use" this notebook on battery.
Hope this helps somebody.
The below is for: Dell G5 15 5587
This laptop is completely useless when not plugged in, if you are willing to keep it plugged in and treat it as a desktop you will get the performance you want, but then, you should be buying a much more powerful device for the price you paid for this "thing", I really can't call it a laptop since it lacks the portability!
Here are few examples of what to expect when you are not plugged in:
I can go on with this list forever, you get the picture...
DON'T BUY THIS UNLESS YOU WILL KEEP IT PLUGGED IN 100% OF THE TIME!
This really needs to be remedied. I havealways steered away from laptops. First, because I haven't really needed one. And second, most have issues.
Well this is my first "gaming laptop". Its impressive while plugged in, but is an absolute potato running off the battery.
Running cinebench, it's almost a 50% performance difference. That's MASSIVE. come on Dell.
New BIOS 1.6 (June 10) for my G5 5590 with the 1660ti is still giving me only 1.67ghz clockspeed and I have changed every related setting I could find. I'm not sure if I'm gonna keep this laptop. I wanted to play some casual Rocket Leage but not even in super low settings did it manage to beat my N.Switch
In case battery extender is enabled. Then do this. Dell Power Manager -> Battery Extender ->Settings-> Reduce CPU Power(uncheck this option). Dell Power Manager -> Thermal Management-> Ultra Performance(select this option). Hope this helps.
I have tried the following things:
- disassembled everything to I could unplug the CMOS
- updated bios
- unplugged battery
- unplugged battery and pressed power button 30 seconds
- tred ifferent things in Dell Power Manager
- tried different things in windows power manager
Still stuck at 800 Mhz. That only small progress I have is to run ThrottleStop, but after reboot or sleep/wake its again stuck at 800 Mhz so not a solution. Anyone that has something for me to try please?
Thanks for posting. Apologies that your system is not performing as you expected, however it does sound that the system is performing as designed.
If you still require assistance and the system is under warranty, you may contact me privately. Be sure to include your personal information (name, address, telephone, email) and your computer's service tag number in your message. Thanks.
If there is no warranty, then you could contact our Out of Warranty team to get a quote for a paid service request.
I hope you are joking 🙂 The issue is that our notebooks are not able to work on battery. Please, dont tell me that its designed by Dell. I can't believe it.
Anyway if you have right, Dell should:
1 - Put an official information somewhere on website.
2 - Close global sale of G -series notebooks
Thanks for posting. Apologies that your system is not performing as expected.
While on battery, what programs are you using? Are you able to check emails?, look up things on the internet? or use productivity programs like Excel or Word?
If you are gaming, what game are you playing when you encountered this issue?
Please respond privately and include your Service Tag information so I can document your case.
So you see those red spikes? That is power Throttling sending the CPU into the dungeon. Literally when I unplugged the power is when the red spikes went up
I found a solution!!!!!! FINALLY after months of searching. Here are the things I did that might have contributed:
1) I did a "windows reset' which deletes everything on the main drive and reinstalls windows from the "cloud" (Dell servers).
After I did this I was still throttling so I,
2) Updated the Bios. I downloaded the firmware from Dell's website: The version is 1.11.1 released 14 Aug2019.
Still, no change to the PL1 power throttling at idle and under load the processor would clock down to 0.8Ghz. As soon as I unplug the charger I'd drop to 0.8Ghz as well.
3) Install the "Dell Power Manager". In DPM under the tab "Thermal Management" You can choose a thermal setting. I did a lot of testing here since it seemed to fix the problem.
Ultra performance is definitely the best when it comes to performance. It seems like the fans spin faster and the power available to the processor is higher.
However, I decided to run my system on "Optimized". It gave me relief from me PL1 throttling problem. Now, I am only limited by my thermals. But the manager tries to balance fan speed and power delivery so that the computer idles quietly and has enough power when under load.
Now under load I never fall below 3GHz plugged in. Battery performance has been much better too.
PLEASE NOTE: I had this program installed before I did the reset and I was stuck with my throttling problem. In Throttlestop I was seeing a PL1 throttle (even at idle) on the core. Under load, my processor would throttle to 0.8GHz and stay there rendering the computer useless to handle the heavy task.
TLDR: Install Dell Power Management and update your Bios. It is possible you may need to do a "reset" or fresh windows install from Dell.
I hope this helps 😄
Similar issues here on my Dell G3.
As soon as I unplug, games become instantly unplayable. Plug in and bam, good to go again. Since this was sold and marketed as a gaming LAPTOP, that's unacceptable. If the system can't perform not plugged in, I'd go so far as to say it'd be false advertising / fraud on behalf of Dell to advertise this as a gaming laptop (as opposed to a portable desktop)<Legalistic statement removed>. (It'd be like a company saying that new car you bought can go 120 MPH top speed, then finding out that top speed only works in your driveway and nowhere else.)
I'm in the process of trying to have tech support address the issue currently. Clean Windows installs, clean driver installs. Trying the Dell Power Management app, Windows Power settings, and NVIDIA power settings did squat. On unplug, system goes to a low power state, no matter what I change.
Either the thing is engineered poorly, or there was some intentional firmware choices made that force CPU throttling / low power state on battery, no matter what the thermals are.
Very unhappy / feel incredibly deceived.
