Thank you for posting on the HP Support Community.

To get the answer to this question, Yes! you can use a laptop without the battery, 

The average laptop battery is good for approximately around 400 recharges cycles. After that, it starts to lose its capacity to hold a charge. 

This is about one and a half to three years of battery life for the average user. As the rechargeable battery begins to fail, the running time of the battery begins to decline.
