Hello, i have a laptop problem!!!

My laptop has 2 problems, it beeps 2 times when it turns on and trhen stays on without me seeing anything on the screen or loading anything else. The second thing is its charges for 2 and 50 seconds then stops just shuts off and i want to deal with this fast as i can. and when it was working it smelled wierd it made me kinda ill. i think its a Two Beeps POST/CMOS Error. but how can i fix it i really don’t know what to do. If someone can help me i be so thankful cause i m really lost on how to fix this problem.
