Repair power cord
The power supply to the Lenovo IdeaPad U460 system might get interrupted if the power cord of the adapter is damaged. Examine its damage after unplugging the power cord from the socket. A broken cord might also cause power failure. The power code can be fixed at home itself. If required, detach the power cord and repair it.
Check power supply
Sometimes, even if the power cord and the power point are good, there are chances for failure. At this point of time, make sure that the connection to the motherboard is secure. If you don’t find any faults with that, then the AC adapter might be malfunctioning. If possible, test the adapter of your Lenovo IdeaPad U460 before buying it, using a multimeter.
If the Lenovo IdeaPad U460 laptop is not able to identify the AC adapter, then it can be due to some trouble in the power socket. Damage with the cable might also cause trouble. An error might occur because of a broken DC-IN jack. If so, replace DC-IN power harness.
