Spin SP513-54N shuts down after overpowering USB hub, CPU stuck out at 0.19% utilization

I was powering a portable hard drive through a USB hub (USB-C to 4 USB A 3.2 Gen 2) when the Spin 5 shut down unexpectedly. The external power input (non Power Delivery) to the USB hub should have been 5V/2A, but I incorrectly connected a 100 watt (5V/20A?) source. This triggered the unexpected shut down, which also fried the portable hard drive (not spinning and smell of burnt plastic). The Spin 5 seems to run OK, except the CPU maxes out at 0.19% utilization (it runs fine for the first few minutes after power-up ), which causes the PC to run so slow it's not usable.

I suspect there has been some internal hardware damage (perhaps replacing the battery will cure the problem?) and the PC needs to be replaced. But I am also wondering if anyone has any other ideas I might try (system settings?).

My PC is a Spin SP513-54N running Windows 10 Home.

Thank you!

    Hi, you charged the regular laptop USB-C port with the hub and that possibly damaged the motherboard, bring the laptop to Acer Services in your country.

    Thank you Puraw! That's what I thought also.

    By the way, I meant max 0.19 GHz instead of utilization, not that it matters.

    If your Spin 5 laptop works then its not its 10th Gen cpu or its Intel Iris Plus Graphics that has been affected, its probably a capacitor that regulates the power to the cpu that shorted out and that is why the cpu only power to 0.19% GHz, as and if a mosfet would have shorted from a high 19V current, the cpu and its graphics would have fried and the laptop would have been unusable and you would not have been able to boot the laptop at all. Take your laptop to a good and experienced technician and get them to pinpoint where the exact capacitor problems is, as they will change it for a fraction of the cost of a as the new mainboard or a new laptop. Good luck.
