So I have had moist damage on my laptop at the end of last year. I had to get my internal charger part replaced so that my laptop would charge again. However, later I noticed that the backlights will not work and if I push F5 or F6 the laptop shuts down. I downloaded Lab Tick and when I click on it in the Menu bar, the laptop shuts down. Has anyone else had this issue? Is there anything I can do? Thank you!
