Hi,
I have a 2021 Lenovo Legion 5 (model 15ACH6H). It has a USB C PD port which supports up to 100W charging.
I have been using a Baseus GaN 100W charger for about a year and a half and, while it's not as fast as the 230W charger brick that comes with the laptop, it's good enough to charge the laptop while using it in Balanced Mode.
For whatever reason, the laptop no longer charges when using this charger. The orange charging light turns on when it's connected, but the OS (Windows and Ubuntu) do not show a charging icon, and in Ubuntu it clearly states that the state of the battery is "Discharging".
I do not have another 100W charger to try with this laptop, but I will say that the charger still works with my other devices - a phone and a tablet, both of which it is able to fast - charge. However, those devices do not require a 100W charging rate, and I did notice that the laptop charges (very slowly) when it's turned off.
Is it possible that the charger can no longer charge at a rate of 100W, or is it more likely that the issue is my laptop?
Thanks.
