Hi rcmurad,
if the LED responded then the power adapter is good, and that the system is recieving the power. just that the power is not getting thru the charging circuit.
for my case, letting the battery drain completely did fix it, and i think that caused this charging circuit to maybe reset.
by the way, before i drained the battery, i also power cycled a few times (total power on/off), with the power adapter unplugged. And also made these setting changes:
Goto Control Panel\Hardware and Sound\Power Options\Edit Plan Settings, and click on "Change advanced power settings" link near the bottom. A "Power Option" window will popup, expand the "Battery", and changed the followings:
- critical battery level to 0%
- critical battery action to shutdown
After the system shut itself down, because the bettery is drained, i waited a few minutes and try to power it back on (just to make sure the battery is really drained). When it failed to power up, then i plugged in the power adapter.
you may want to try the above and see if it can help with your problem. good luck!!!
