I have an HP Pavilion DV4. Computer has been great never had a problem. However, today I went to start up and nothing. Power cord is plugged in, but no lights are illuminated at all. Will not start. I tried a hard reset - removed all sources of power ( battery , power lead ) and held the power button down for at least 30+ seconds. Re-connected the power adaptor only ( not battery ). Laptop would still not start.
What can I try next?
Thanks.
