Chosen Solution

done SMC and NVPram resets no change, the dc-in heats up and the battery doesnt charge. What other possible parts could it be if the battery doesnt charge but is detected? could it be a faulty dc-in?

the kernel can run on low cpu if i have it in the smc reset mode (when the fan noise is spinning i presume and the charger light is off)

Your battery is bad.
