I’ve been having a lot of fps stutters and lag spikes in games such as Fortnite and overwatch, I’ve tried everything, I cleaned the dust off my fans and reapplied thermal paste, I heard that undervolting the cpu might help as my laptop still goes up to 90 degrees, but when I opened the laptop I found out that the cmos battery had not been connected ever since I bought it, I have a gtx 1650, i5 9300H, 8 gb ram laptop, is there anyway I can undervolt my laptop without a cmos battery
