I don't think the kernel or any userspace program is capable of stopping a laptop battery to charge so this is a hardware issue, not a software issue. Is the indicator flashing yellow before you even get to the boot menu?

Yes, it is still flashing yellow even the laptop is closing. I will try to dismantle the laptop to see whether the power interface is loose. Thanks~

The reason is the power interface is loose.
