The reason of the led flashing of the lenovo laptop adaper:
1. Remove the battery and see if the computer can be charged and run by the laptop charger. If it can be chanrged then that is because the indicator light of the power adapter is broken, if it can not be chanrged, then that because the power adapter charger is broken, then you need to change the notebook adapter!
2. do not remove the battery, and to check if the power charger can charge the battery successfully. If can, it means that the indicator light of the power adapter is broken!
3. If neither of the above two is the case, then the computer is broken!
