ASUS Chromebook C523NA Slow Charging (USB TYPE C)

idontknowanything01 commented 1 year ago

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 1) In your firmware once i connect the charger the charging indicator change its colour after 5 seconds. 2) My OS (Linux Mint) show the charging indicator after 30 Sec or so. 3) Once i disconnect the charger the charger the charging indicator change its colour instantly. 4) 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

idontknowanything01 commented 1 year ago

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

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?

MrChromebox commented 4 months ago

sounds like ChromeOS was doing something with the PD controller to adjust the charge rate that Linux isn't

shiptux commented 4 months ago

Is there any helpful of acpi_call?

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.

cmbuck commented 3 months ago

@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.
