i already have the schematic, but how to determine if BQ24721C is bad??

Re: Satellite L505D MB 6050A2302901-MB-A02

attach it here!
do you think that we have some JEDI MIND tricks that we can see that schematic and know whats wrong?

May the force be with YOU

Re: Satellite L505D MB 6050A2302901-MB-A02

If you don't have any voltages on BIOS, first check 3.3V & 5V regulator (U6100)...
In order to help you need to post voltages of all pins...
