Laptop shutdown issue when on battery power.

[saraogishivam3]

Battery or AC: Battery
Model: Asus ROG GA503QM
Frequency of occurrence: Regular
System: Windows 11 HomeS========================
Detailed description: After I updated the laptop operating system to Windows 11, whenever I close the lid and leave my laptop for more than a few minutes, my laptop shuts down. I've tried all solutions I could find online but could only change the settings for when the laptop is charging.
Now when my laptop is plugged in the laptop stays asleep and retains all the open apps when I wake it up. However, this is not the case when it's on battery. All of the applications are lost and I've lost some information because of this.
I've tried to change the group policies and tried to change the power plan settings through advanced plan settings but nothing has worked for the "on battery" options.

I left my PC for 15-20 mins it shutdown completely. Even while on power. Sometimes Fans are on full power only browser is used at that time. Which is really hampering my daily productivity.

If possible, can you have a video?
