I need schematic of Compaq Presario 700 Battery back circuit

[Guest]

Hallo!

I want to replace the original 18650 (2000mAh)Li-Ion battery pack
with 18650 (2400 mAh) li-ion batteries.
I replaced the batteries but the battery pack does not go in charge.
(battery status 0% even after 40 hours of charge...).

The battery pack is recognized by the notebook with the correct name,
and type, but battery charge does not happens, but the led of charge display that the batteries are in charge.

I need the schematic to solve this problem!
Thank you in advance!
