Dell Inspiron N5110 beeped 3 times and won't turn on

hi
i have bought a dell inspiron n5110 for two month now. after 20 days one morning
i tried to turn it on and it beeped 3 times and went dead i took it to support
center ( it has warranty ) they took it and fix it in about one hour and told me
it was a bios failure and if it happens again warranty wil not cover it and it will
cost about 150$ after one month today it beeped 3 times again and after that went
completely dead.

i am not a hardware expert but i can handle my and my coworkers computers pretty well
but since it has warranty woid labels i cant check anything.

i have already tried
pushing power button for 30 seconds without connecting battery or charger.

Usually , 3 beeps mean your Memory/Ram needs to be checked or is bad…

Hi Matin ,

My name is Angel. I work for the Dell Social Media Outreach Team. The 3 beep codes indicates that its a motherboard or memory failure.
Try to reseat the memory and boot the system and check.Please use the following service manaul link to know how to reseat memory.
