hi
i change bq24725 but not help ... all round this ic seem ok

Check with oscilloscope data exchange between battery and multicontroller. Then if impulse is present check where lost your charging dc voltage. 2-3 times this malfunction is from malfunction capacitor in circuit output mosfet wich charging battery and few times malfunction is multicontroller.

thanks for your fast reply

i have oscilloscope 50MHZ

but what do you mean from multi controller ?? and what is the signal name you told me to check ?

hi i check the bq24725 again cefully i mistake that voltage in older post
this new test are (REGN=6) is ok now but the HIDRV=0
is that good or missing voltage ??

You use an original battery, or Chinese (fake)?

i think battery not orginal but i test this battery with another laptop and working fine

when i plug battery and then connect 19.5v DC from source DC supply i see the laptop for 3 second use about 5.3A current
like laptop board shorted .... and then current go fine about 0.78 '
