I was updating my drivers for my new Lenovo Yoga 920 laptop and I tried to use this driver: https://pcsupport.lenovo.com/no/en/products/LAPTOPS-AND-NETBOOKS/YOGA-SERIES/YOGA-920-13IKB-GLASS/do...
However, the update keeps failing and the Type C ports do not work now. I can't charge my laptop. Luckely I am at 75%, so I have about 3-4 hours to fix this before I'm forced to take it to service.
I tried this solution: https://www.gfisk.com/lenovo-yoga-pd-firmware-update-failure-ccg4-two-port-usb-c-controller/
but it doesn't work for me. I'm getting desperate
I'm supposed to press the power button for 8 seconds and the powering should be back on, but for me the lap top goes off after 3 seconds of holding the power button. I keep pressing the button of course to see what happens. But, when I turn back on, the battery still won't charge. And the firmware update keeps failing. I tried everything according to instructions, but with no avail.
Please help! My laptop is off now, so I will wait for solutions here before I turn it back on.
Solved! Go to Solution.

If we assume that the issue is purely as a result of the failed driver update which has somehow broken the USB C ports ability to charge, then there is every chance that a System Restore will work as it should just be a software issue. But of course it does depend upon whether you have System Restore actually turned on!
I’m also assuming that you have backed up all of your data as the clock is now ticking!
I have had an occasion when System Restore initially failed to work on my 920 but rebooting into Safe Mode and running it again did work. Hopefully you won’t need to do that but be aware that it’s another option if the System Restore procedure fails the first time.

Well, it's not a driver I think. The tool that I used is a utility that writes directly to the firmware and I think it has nothing to do with Windows.
I will try system restore as a last resort. Will wait to see if I get any other suggestion.

Thanks for your input @yigit. Unfortunately, it is not possible to unmount the batery. I would have to unscrew the bottom, but I don't want to mess up my waranty.
Any other way to do the thing with the power button?

The way I fixed it was to run msconfig, in the "General" tab I selected "Diagnostic setup" and rebooted the laptop. When Windows booted, I ran the PD Firmware Update utility and it worked! Oh, what a relief
Thanks everyone for their help.
