RE: Inspiron 3521 won't start up
Thanks for writing to us.
When did the issue start? Was there any hardware or software changes done recently?
You can try remove the memory modules and then try to power on the machine with one at a time and check if it makes any difference.
instructions can be found on support.euro.dell.com--enter tag# --submit--manuals
Is it possible to record the sound and send us as an attachment or a link.
Also when it powers up fine please update the BIOS as well from support.euro.dell.com.
Do provide us the system tag# and also confirm the name the system is registered under by
clicking on my name in blue and then select send a private message. Also let us know the contact
number and email address.
