I’m working on an HP DV6000 laptop. Its symptoms are as follows: With the battery removed and the a/c adapter plugged in, upon pressing the power button the status lights flash for roughly 2-3 seconds then the unit turns completely off.
I’m in the process of taking the unit apart. I will have a better diagnosis come tomorrow.
I have noticed though, that when I do a Google search for “HP dv6000 laptop turning on then off immediately” yields no results for what I am actually looking for.
I hope that with this article, you will find this and figure out a workaround for the power on then off problem.
