Sir,
We have a lenovo laptop. we were using it with battery backup. all of a sudden the total power supply got drained and the laptop got shutdown in few seconds, as we didnt notr that the battery backup was not sufficent.
After then we connected the power supply, but the power supply in the laptop is not blinking.The power led in adaptor is blinking.but not in the laptop. What will be the problem. Kindly contact me at 9176046263
Regards
Ramesh
