I have a dr2418nr hp pavillion laptop its a 05/06 model and it hasn't worked for a while. i have no idea what is wrong with it but ive been doing some digging and found that it could be several issues it could. some people that ive seen has the same issue and say its a power issue its not getting enough power. A buddy of mine has told me it may not be passing the post test on startup. when i turn on the laptop i get l.e.d lights to come on and sometimes you can hear the disk drive click a bit but then stops and nothing happens. i took out the battery and held down the power button for 15 sec to drain the power in the pc and then left battery out and plugged in the AC cable and then turned it on and the fan kicked on and the touch pad on/off button was blinking from orange to blue. anyone able to help me? please.
