i would use the original [http://h10032.www1.hp.com/ctg/Manual/c01035677.pdf|Maintenance and Service Guide] for that model.
but to be honest. the dv6000 and dv9000 had some real issues.
never heard of the thing you describing ("normal" charging related issues are from a faulty charger socket or a dead battery)
the dv models are "known" for capacitor and graphics processor issues
