两个usb充电口（方便起见分别命名为充电口1和充电口2），之前老用充电口1充电，但是今天充电口1突然不能充电，该换为充电口2可以充电，但是充电口1插上扩展坞可以给手机充电。检查电脑更新问题时发现有一个驱动程序安装失败，不知道是不是因为这个原因。

Hi,

Here’s what you can try. Since the update screen shows a failed installation for the HP USB driver, it’s likely related to why charging port 1 stopped working. You can manually reinstall the latest USB or chipset drivers from your PC manufacturer’s official website, as Windows might have used an outdated version. Then, open Device Manager and check for any devices with a yellow exclamation mark, these indicate driver issues that can often be fixed by selecting “Update driver” and choosing the correct version. It also helps to disable the option that lets Windows turn off USB ports to save power, as this can cause inconsistent charging. Finally, run the Windows Update Troubleshooter to repair any incomplete installations. If charging still doesn’t work afterward, please share whether the port can still transfer data when you plug in a device, This helps confirm if the issue is related to power or the USB driver itself.

Kind regards,
