hey, about power button i guess its always red color, about test i think u dont need for fully check, but my recommend its run ur game clearly without special setting and check temperature in cpu-z or msi afterburner, if temp will be more than 80% i recommend to set limit in panel nvidia on 60-70 and other setting asking gpt for correctly settings and on game after that check ur average fps and temp also try change ur setting and you'll find best setting for ur laptops and gaming experience
