Every time start laptop will beep 2 sounds from hardware there....why like this?get problem with this or not? mine is asus n56j, i just bought it.

On startup, computers perform a Power-on Self Test, commonly referred to as a POST. If problems are found while booting, you can usually diagnose them using the error codes displayed on the screen. However, if nothing displays on the screen, the computer might use sounds (i.e., beep codes) to tell you what is wrong. Many of these errors indicate hardware problems that a service technician should fix.

Note: Many BIOSes will have different beep codes even if they appear to be from the same manufacturer. This is because motherboard manufacturers reprogram codes to reflect their own customizations. You can often go to the web site for the motherboard's manufacturer to find the updated codes, but you may find cases where the manufacturer simply does not document the changes.

2 Beep sounds in ASUS means that the Hard Disk test has failed. There is a very possible chance of a Hard Disk failure.

I would recommend you to contact the computer manufacturer in this regard.
