I bought a HP Pavilion dv5-1036tx laptop back in 2008.
It currently struggles to boot on. When I press the power button, the lights all blink and then shut off. There doesn't seem to be a problem with the power brick as the power light is always on and if a battery is plugged in the light indicates charging (even though my current battery is dead so I always use the adapter).
I've tried opening up the laptop to figure out the problem but have not been able to.
On occassion, the laptop strangely does boot up - the last time it did this, I was able to keep it on for a week. That's the thing - if it boots up, it works fine, but it won't boot up consistently (i.e. if it goes to sleep or I power it off there is no guarantee that it will boot up again).
The problem is similar to what is shown by the person in this video: http://www.youtube.com/watch?v=C_jeVjiSeNw
Please help in fixing this problem.
