E520 series--Laptop doesn't start untill I plug AC power

Hi,I am facing starnge problem with my laptop since 3 days.Even if laptop's battery is fully charged ,if I try to start it it doesn't respond with battery (it gives a feeling as if battery is fully discharged,even if it is not) soon as I plug AC power and I try to turn laptop on it get start and then it all works fine even if I remove the AC plug.Seems problem only when I start the laptop.


Do anyone knows what exactly the problem is ?
