i tested my mobo with a dc tester and its getting the right voltage, what was strange tho at the end where the battery connects into theres 5 prongs, only 3 prongs gave a reading (and the lil soldered dots behind them) the 2 read 4.something and 1 read 3.something so im unsure if that means its not the right voltage, no theres no static discharge in there, my cpu looked fine, took it out no burnt marks then reapplyed thermal paste, the fan looks alright, when i try to power it up the blue lights on the keypad come on for a sec but no fans or beeps. Laptops a hp pavilion ze4906us
