[atif.chaudry]

Hi there, I have a problem with my dell laptop N5110. It was shut down perfectly today but after one hour when I tried to turn it on again its not turning on. Power button and other LED lights are turning on for a while but nothing appears on screen. It also beeping thrice a time and so on

Hmm beeping usually not a good sign. Here is some info on beeping from Dell. Be sure of the number of beeps. As they mean different things.

Also, if the device is under warranty, then contact the manufacturer. However, if not, then you can either try doing the work yourself, or take it to a local tech.
