Strange problem in Asus K56cm

[maxoscar]

Hello

I have the below problem in Asus K56cm

The laptop is unable to boot from the AC alone or from the battery alone
Not been able to power on the laptop
By accident I have discovered that if the AC and Battery are exist together I was able to power on and boot but based on battery power

I have unplug AC Then I was unable to power on the laptop and vise versa
the only way is to have them both connected and it will bot based on the battery


Any suggestion to fix this issue

thanks in advance
