Question Microsoft Surface Pro 9 not charging via a USB-C 65W PD charger ?

[salilsurendran]

I purchased this 65 W USB-C PD Charger to charge My Microsoft Surface Pro 9 and this worked till recently, always fast charging my laptop. However, since the latest update, when smart charging was introduced, my 65W USB-C PD charger is no longer charging my Surface Pro 9. I have to hit the power button and restart the Surface Pro 9 for it to recognize that it is connected to a charger and start charging. Once I disconnect the PD charger and connect it again, the Surface Pro 9 no longer recognizes the charger and doesn't charge.

However, the original Surface Power Adapter always works and always charges my Microsoft Surface Pro 9. I believe this problem was introduced by smart charging and when I try to disable smart charging I am unable to do that as shown in the attached image. When I go to the Surface app and then go to the battery and recharging section, it says smart charging is already paused and the option to charge to 100% is completely disabled. How do I fix this?

is only one port of the charger used while charging the laptop? don´t plug in any other cable, even if not connected to a different device
are you using usb-c to usb-c cable connection to charge?

try a different usb-c to usb-c cable

rma the charger

Yes, only one port of the jar of the surface pro 9 is charged via the USBC charger. The other port is not in use. The charger used to do fast charging using the same USBC cable. So I don't believe that there is anything wrong with the cable or the PD charger. The issue is with one of the Windows 11 updates that introduce smart charging

remove the updates and try again

Select Start > Settings > Windows Update > Update history > Uninstall updates .
2). On the list that appears, locate the update you want to remove, and then select Uninstall next to it.

I did this:

• Open the Command Prompt as an administrator.
• Type powercfg -restoredefaultschemes

and my 65 watt charging clock started charging again at full speed
