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. pushing power button for 30 times without connecting battery or charger.
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. http://support.dell.com/support/edocs/systems/insN5110/en/index.htm Thanks & Regards Angel Dell Social Media Responder
