Thank you very much bro you helped me clear my misunderstanding everyone here i’m very thankful for your response. I’ve repaired my Pc with all your help. I thought that the first two pin were the normal and the bottom two reset. since i had jumper in the bottom two pins without removing them i’ve had no issues booting up or bios reset screen. Long story short i was putting the jumpers the wrong way. the battery seems to be fine as it is holding all the bios data even after shut down. Thank you all for helping me.
