first, why you cant find info on the bq8030xxx (see last post)

i am trying to fix the same problem
http://forum.allaboutcircuits.com/showthread.php?t=55241.
the battery voltage is reported right and it even determines the proper capacity (i only put three new cells) but current is 0. So what i was thinking was it must be able to measure the voltage some separate way and something is stopping the current from flowing. So i found a meltable fuse on the back. http://www.sonycid.jp/en/products/dd6/sfh0412b.html
It seems to be open. I ll bypass the fuse and report.
everyone is gotto protect their revenue streams. what load of crap.
