I've looked up and all i found were unanswered questions only !

Why do we face performance issues like lag in games and decreased FPS while the laptop is being charged ?

If i want to play with some decent FPS, i need to unplug my laptop and it gives a maximum of two hours of gameplay !

any solution is also appreciated :):bounce:

see if the cpu frequency dips below 1.45ghz in cpu-z. you may have to wait a few minutes for the cpu/chipset to warm up

check the advanced power setting> processor power managment> maximum processor state and make sure its on 100% when plugged in.
what is the brand and model is your laptop?

Yes, i put every setting into maximum and even turned off the hard disk power saver too !
it's performing excellent on battery but the problem arises when i charge it !

go to AMD Catalyst and go to power then select "maximise performance" on battery.

Also try running prime95 for about 30 minutes and see if the laptop is throttling (underclocking) with cpu-z.
check temps with hwinfo

or maybe theres application tat runs once your laptop is plugged in thats hogging the cpu

Hey, I found the solution for my problem.
It seems the sable versions of BIOS by lenovo had these issues.
I installed a beta version of BIOS (v 2.5) and everything's good.

Previously, the CPU clocked 1.9 GHz on charging, Now it remains at 2.4 even when on charging.

Anyways. Thanks, epioverclock !!
I appreciate your help :)
