If possible try a mains charger. A computer USB port sometimes isn't enough to handle a very discharged battery, particularly on a laptop.
Try a different USB charging cable, maybe try the charging dock if you have one available.
If necessary check the charger and cable are still good by connecting another USB-charged device and see if it charges.
Leave it on the AC adaptor to charge overnight, see if it works when you hit the power button in the morning.
Test with a known good battery, and/or test your battery in another (borrowed?) phone if available. A bad battery can prevent startup even with a mains charger attached.

If these don't produce a result you may be looking for a replacement phone. Even with a corrupted OS you should get at least the LED as it tries to boot.

Thanks a lot man but If the LED doesn't show it's mostly likely broken ?
