Question Legion 5 Ryzen 7 Lags when turned off at night and turned on morning.

Jan 2, 2021
My Specs
Ryzen 7 4800H, 16 GB Ram, GTX 1660ti 6GB, 512 SSD.
I got this problem after some time.
at night I turned off the laptop and when I turned on a laptop in the morning it lags like taking time on the opening program, start menu, like of old computer
to resolve this I have to plugin charger for some time and restart or unplugged after some time and works well for the whole day.
this is strange issue yea?
I tried these all methods :
