Thanks for the schematic.I wander if ever someone have this weird breakdown.Firstly the laptop battery is dead.When i plugged the charger into the laptop, it turns on without pushing the start button but when i switched it off and restart it by pushing the start button.....i can see some led but the screen is black. i've to wait 3 hours to begin what i've said before.

This laptop model does not initialize (black screen, no POST) WITH A FAULTY RTC BATTERY. Also often there as a bad contact between battery holder and the battery, so please check the voltage directly on the battery holder pins. Put a new RTC 3023 3V battery and check for the normal POST.
