iv'e had my laptop for 8 years now , and recently it turns off by itself . when i switch the power plan to power saver it stays on but it affects my games alot (the fps drops from 60-70 to 15-20) and i just wanna know if there's a fix and what's causing the problem . (if i pick any other power plan it turns off , even balanced)
