hi all , when i press power button with only battery the charge led is blinking for while and the laptop dose not turn on , but when i connect ac power the led is not blinking and also laptop dose not turn on , all voltage and bios are ok in both cases , i have changed kbc but nothing change , plese i need help ............

which means
if

lid_close#, ac_in#, kbc_x1, rsmrst#, ecrst#?

all signal are ok
lid_close# is high
ac_in# is low
rsmrst# is high

what voltage do you have in pin 3 acset?
because if you have less than 1.27v AC_IN # should be at high level
