I have a question for someone who can help. I have a HP Pavillion DV9000. When i turn on the laptop, all the lights come on then shut of then come on again and it seems to stay on. This question is about the charger to this laptop which is a replacement charger. It is a 65 watt charger but the original is a 90 watt charger..... would that make a difference in the laptop coming on or functioning properly? Thanks in advance.
