My Dell studio 1558 in booting because I can hear sound of fan but there is no display. I tried to remove battery & hold the power button almost 1m, an tried to boot with battery an without battery with the help of power chord. I changed my both ram ddr3 an hdd also but same. I tried to diagnostic with fn+power button but no response from lappy. Pls suggest me what to do ? I also called dell care but they denied to provide any service. I called to local dealers they told me that It may be processor failure. Guide me on this. Thanks
