I have a HP zt1260 laptop. All lights are on so I right away thought it was the motherboard. I proceeded to take the whole thing apart and see what I could find, Everything looks fine, also very clean. I started to do research on the net and found if you hold fn button b button and power button with battery out you can plug in the ac and it does some sort of reset. so i put it back together and it works. ok so i hit the pwr button and nothing, if i keep hitting it i get like back feed from each one of the speakers at diffrent time and no hdd spin or fan or anything. but if i use the "personal dj" cd feature at the front with a music cd it plays no prob. so the only light that stayed on was the cd light period and i got that to go off - dont know how, i have probably taken it apart 5 times. reset button does nothing, battery light caoms on and charges no prob.
If you have any ideas please heeeelllppp
Thanks in advance
