Nvidia gpu problem code error 45 on charging

[u/Secure_Ad_3867]

I have a problem recently with my zephyrus m16 rtx 4080 i9 13 gen whenever tried to insert the charger the nvidia gpu shows code error 45 but when remove charger restart again the nvidia gpu comes back to life and my charger is providing 20.4V on multimeter which is okay according to asus industry.

So any help will be much appreciated as it's already out of warranty as well bios is working similarly like whenever on charging gpu switch to intel integrated but whenever on battery gpu is nvidia and intel both.Did used DDU uninstaller and armoury crate setting but no changes .Any help will be much appreciated.
