[solved]820-2879 Does Not Stay On With Battery Power

[supamodz]

Hi louis, hey guys im back to old crap again, working on a 820-2879 the issue i'm having is that it sees the battery when on with the charger plugged in it even charges the battery, but as soon as i unplug the charger lights out as if i'm testing it without a battery. When plugged in it calculates battery life and sees the battery that's whats confusing me board looks ok any ideas on what is going on here.

If it sees the battery and charges the battery with the charger plugged in but doesn't work off of just the battery. hmm.

what is pp3v42_g3h when the battery is plugged in by itself without the charger?
