2, may be caused by a battery failure. Lu master with the next test, the battery work
Look at the current loss of the battery to determine whether the battery is damaged.
3, may be the motherboard power control, charge and discharge circuit is damaged due. If the master with Lu detection
The battery is good, that is, the motherboard power supply and discharge circuit is damaged.
Please go to the local after-sales inspection as soon as possible, and replace the new module to solve;
Laptop power adapter has been ringing, and the charging indicator light repeatedly flashing, there are two aspects, the reasons for a power plug voltage instability caused by abnormal reasons, two power supply configuration hardware problems;
Troubleshooting one: you can pull all the cables down, re-connected to the lower right corner of the monitor power indicator light on the switch when you can replace the 220V power jack, the monitor power indicator light and flash a bit like this The situation is poor contact inside the card? The power adapter of the AC power cord quality is not good, especially the plug part of the internal contact is not good, the resistance value is unstable, from small to large, resulting in changes in voltage from large to small.
If put on a 220V AC power cord plug, connected to the power adapter, the power plug problem can be resolved;
In the above operation still can not solve the power adapter failure, you can determine the fault two power adapter hardware problems, need to repair or re-purchase a laptop power adapter.
