Question Laptop not turning on

Mar 3, 2020
Hi I have an old dell latitude and I was bored and wanted to fix it the only issue is it turns on then automatically turns off and only the Leds light up I’m wondering if it’s the battery and the cpu ? It won’t even turn on when unplugged ! Also some of the pins from the cpu are bent and one is missing since I’ve had it in a container and it must of hit something when I moved it ? Just have been wondering ! The model is an e5430!
