most likely damaged motherboard and needs to be replaced.
Liquid in a laptop is 95 % of the time instant death.

video that show what sugary liquid does to mobo

MERGED QUESTION
Question from itssagets123 : "Laptop won't turn on light comes on then goes of???"

Had laptop 3/4 years 2 yr ago spilt juice on it didn't work light come on of and yesterday it worked everything worked was on it for 30 mins then I thought I need to close the laptop and start it back up again and the light comes on and then goes of it's like it wants to start up but it don't any suggestions ???

component either damaged or shorted to ground. disassembly and clean with 90% isoprophyl alcohol, be gentle

I opened it up and used a vaccume to clean it I will try what you said thank you it's crazy how it worked after all that time and now it don't want to 🙁

dont use anything else than isoprophyl alcohol 80% or more is okay also but 90% better. dont use vaccuum to clean components because it can give dishcharge and damage your motherboard components :/
You dont need to clean whole motherboard, just look all connectors and places, even like keyboard connectors etc which have signs damage, be gentle really. Best thing is to buy toothbrush with SOFT brushes. Dont use anything else than soft ones. It drys faster if 90% or more but dont worry isoprophyl alcohol isnt conductive so no shorting :=)
Ofcourse more easily breakable things like screen or keyboard connectors with something else than toothbrush, maybe some wipes or paper

upload some high resolution pictures from both sides of the board after cleanup. Remember remove heatsinks and processor and tapes if you can see juice leftovers could be under there
