Have an old Presario 1200 laptop. I have re-conditioned the battery according to manuel. After full charge, computer will run approx. 2 hrs without charge. Problem is when computer is fully turned off and A/C power removed. After only 3 days (maybe less). Computer will not boot without A/C power. Battery shows as 0%. But, battery re-charges to 100% within an hour. Does this sound like a battery problem, or a computer hardware problem? Thanks.
