Hp laptop takes 15 minutes to power on after clicking the power button

[Talos1]

I have had my Hp laptop for 3 years now. It has been working perfectly, up until 2 weeks ago. It would not turn on when I clicked the power button. After clicking the power button, 15 minutes later I noticed it just came to life. Sometimes it doesn't turn on at all for days, but sometimes I click the power button and it boots within 15-30 minutes. When i click the power button, nothing happens at all for that duration. No fans, no lights nothing. The only light on is the power cord button that is always on when i plug it in. I did replace the power cord, and tried cleaning out the insides, it did nothing. Should i just replace the motherboard?

Ps. Hp pavilion dv6-6c43cl

See if your mobo has a power switch on the actual board itself. Power it on that way and see if the problem persists

There is no power button on the motherboard itself. Thanks for your reply.

Try with battery alone and also try removing battery and powered with AC adapter only.

I've had this problem with an old XP desktop, the only solution i found was to replace the motherboard and ram sticks. have you overclocked OP?
