CPU clock speed down to 0.55Ghz when charging

Hi to whoever can help me.

General Information:
I have the Framework 16 with the GPU module installed.
I charge via the official charger (EU model) on the back left side.
The only other thing connected is a mouse USB Bluetooth connector on the right down port.
The bios is on the newest version and the drivers have been updated to the newest version.

The Problem:

When i plug in the charger the CPU throttless down to 0.55Ghz and does not speed up again.

Further information:
I just noticed, when my clock speeds are low the fans are basicly not running (no noise), i just restarted the Framework 16, now the fans are running full speed and the clock speed is constant arround 3.2Ghz when plugged in.

After disconnecting the cable and reattaching it the clock speed stays stable. Can anyone help my why the clock speed is sometimes slow and other times not?

After using the Laptop for 3-4 more hour`s i reconected the Laptop to the power cable again, and the same issue shows, clockspeed down to 0.55 no fan sounds (also fixed after restarting)

Fast help, with good instructions are welcome.

And sry if i am not the first asking this questions, other threads i found regarding this issue could not help me

This is a common problem with the bios of this model they have yet to fix. Which bios version are you on?

Best advice I have is to reach out to support so they know more people are experiencing it.

I am currently experiencing this exact issue. I am on the latest framework drivers and bios (which supposedly fixed this). Power saver in windows is disabled, battery is set to 80% charging. It may be related with switching between iGPU and the main GPU; without rebooting, just toggeling the switch by closing an intensive application has restored my CPUs performance. Switching back to the main GPU has pegged the CPU again at 550MHz.

I’m having a similar issue since updating to the latest BIOS, but only when using one specific 100 watt car charger, which before the BIOS update was fine. It still charges fine, just CPU suddenly throttles down to .55 Ghz and laptop soooo laggy. Unplug the charger, it instantly goes back to normal and CPU Ghz levels jump back up and zero lag. Plug it back in, instantly back to .55 Ghz and almost unusable. Plug into a different charger, even a mere 60 watt one, and it’s fine.

The practical solution just use a different charger, though clearly something weird going on with the latest BIOS update. The issue only appeared directly after installing that.

Update, I’ve now started to experience the same issue with my other chargers purchased from Framework. Plug it in, it drops into some sort of ultra low power mode which is unusable, unplug, everything back to normal.

Ok, for anyone having the same problem, I figured out what is triggering the BIOS bug. It’s a lower power USB-C source, even IF you have a higher power one connected. If the higher power one is connected second, the ultra low clock speed mode stays regardless.

In my case, my docking station has 10 watts going to it from an external power source as it needs that. If I connect it first, then connect my 240 watt usb-c charger, my Framework 16 will lock into the low power mode regardless, though otherwise charge normally with the 240 watt charger.

If I unplug the docking station, it goes back to normal. If I plug in the docking station AFTER I already plugged in the 240 watt charger, it’s fine and functions normally with high clock speeds.

My car charger is 100 watts and worked before the BIOS update and charges fine, so not quite sure what’s going on there. But I’m guessing the charger itself must at some point go into some sort of low power check mode to see what’s plugged in or something and that triggers the BIOS bug, and then it doesn’t matter from there if the power ramps up to 100 watts, the laptop won’t get out of that mode.

FYI i’m only having the BIOS Bug when the external GPU ist installed. So i only Connect it when i really need it. Not optimal and i am still hopping for a fix but it works for now…

Or restarting the Laptop when installed…

so i discovered another issue while troubleshooting this one which may or may not be linked: after doing the EC reset procedure (shut down laptop, disconnect everything for 60+ seconds, turn back on by holding power button for 10+s) i cant seem to use the dGPU anymore while a second monitor is hooked up. This is getting very difficult to troubleshoot. i have also changed sleep to hibernate as suggested in another forum post with a similar issue, perhaps the new issue is linked to this

EDIT: reinstalling the same up-to-date firmware package has fixed this issue (for now), and at least in this session ive not had the CPU locked to 550MHz. i really do hope we find a solution to these intermittent failures, they are very frustrating

I’m having the same problem. At first, for me, it seemed to be connected to the screensaver. Once that kicked in, the CPU dove down to 0.55. So I turned off the screensaver and it worked for a while, but since today it throttles out of nowhere, Sometimes after 1 hour and sometimes after 2,5 hours.

I’m on BIOS 4.03 and with the latest driver package installed. I tried reinstalling the BIOS update and power cycle, disconnected battery etc., since it seemed to work for some, but alas not for me.

When I first installed the BIOS update I had the problem of on side of the laptop the ports didn’t work and I got that working again, but then the CPU problem started. I have no idea if those are connected or not.
