Yes, you can fix the problem by pressing the power button for 20 seconds.

Yes, the problem is solved by changing the BIOS version (from A6CN56WW to A6CN58WW or from A6CN58WW to A6CN56WW), it does not make any difference between the old version to the new version or the new version to the old version.


But when you use this solutions, the problem is not solved permanently. Unfortunately, it happens again and again and then you will use one of the above again.

 

If you want to fix this problem permanently, YOU MUST CHANGE(replace) YOUR POWER CABLE

 

i changed my power cable then everthing is OK now.
