I have a hp dv6000. running vista. i can’t get it to go to the post screen. it turns on, lights come on then turns off nothing on the screen. i have tested memory battery and charger. when the power cord is plugged in i see the charge light for about 30 seconds then turns off. i’m thinking dead mobo any other things i can do to test. i was also thinking about reseating the cpu and taking out the cmos battery.
