ASUS Chromebook C523NA Slow Charging (USB TYPE C)
I am currently using coreboot 4.18.2 UFEI firmware My ASUS laptop comes with a 45W fast charger using type c interface for charging it taking 3-4 hours to complete the charging but in unmodified bios it took only 45 min to an hour.
I restored the default firmware and found the hardware is fine and charging is happening at the speed before firmware modification.
A few more details
- In your firmware once i connect the charger the charging indicator change its colour after 5 seconds.
- My OS (Linux Mint) show the charging indicator after 30 Sec or so.
- Once i disconnect the charger the charger the charging indicator change its colour instantly.
- Once i disconnect the charger the charger My OS stop showing the charging indicator after a min or so.
OS driver is responsible for negotiating charging speed, make sure the cros-ec driver is loaded/working
Thanks a lot for the replay can you please elaborate a little bit about how can i install cros-ec or check its installed or not any how to link will also work thanks again.
Not a solution, but a bit of a workaround: On my Asus Chromebook C423 running Xubuntu 23.10, i can get fast charging if I completely shut down the laptop, connect the charger and boot up, but if the cord is unplugged and re-plugged in it goes back to super-slow charging. Did anyone ever find a solution to this?
EDIT: I just discovered that I don't require a full shutdown -- going into deep suspend and then connecting the charger gets me full speed charge that persists when i wake from suspend.
Some useful commands for debugging slow charging:

I'm observing the same issue on two different Asus C302 devices. On ChromeOS the devices appear to charge normally, as expected (full charge from ~40% in <1hr). After flashing new firmware and installing Linux, both devices charge very slowly.
Additional details and troubleshooting steps below:
- I have two Asus C302 (Cave) devices: Device A running PopOS 22.04 and Device B running ChromeOS
- Device A exhibits slow charging (ETA of 10 hours to charge from ~40% battery SoC with 65W USB-PD charger)
- Purchase new aftermarket battery, Device A still exhibits slow charging even with brand-new aftermarket battery
- Insert Device A's OEM battery into Device B which is running ChromeOS. Battery charges quickly (40%->100% ETA approximately 40mins) Failure follows the device, not the battery
- Flash MrChromebox firmware onto Deice B following instructions from chultrabook.com. Install Ubuntu 24.04 on Device B
- Device B now exhibits slow charging failure identical to Device A running PopOS 22.04

upower indicates the battery is charging at ~2.5W which is really low.

I was originally concerned that this was a hardware issue, but the sequence of steps I noted above strongly indicates a software cause.
Is there a way to investigate how much power the battery is requesting, or how much power the EC is instructing the battery charger to pass to the battery?
sounds like ChromeOS was doing something with the PD controller to adjust the charge rate that Linux isn't
I have the same issue on redrix, howerver after upgrade my kernel to 6.6.43-chrultrabook(https://github.com/chrultrabook/debian-kernel), everything of charging works fine, include rapid charge.
@shiptux Glad to hear you've found a resolution. I tried to replicate your success but I'm still observing my charge rate being limited to 2.5W on the latest chultrabook kernel.

In order to install the custom kernel, I took the steps:
- Clone chultrabook kernel repo
- run
./build.sh - install the resulting deb packages
sudo dpkg -i *.deb - Manually edit my grub config to boot the new kernel
Did I miss any steps? I'm still relying on @lee321987's workaround whenever I need to charge the device faster than 2.5W.

I don't install the kernel manually, actually I installed it by run the https://github.com/WeirdTreeThing/chromebook-linux-audio scripts (deb_kernel_url="https://nightly.link/chrultrabook/debian-kernel/workflows/build/main/debian-kernel.zip" ). I will try your steps later

I am trying to add this patch(https://github.com/chrultrabook/debian-kernel/blob/main/patches/i2c-Add-device-property-for-probing.patch) to my distribution's kernel. Everything works well including the battery charge speed.
