I'm trying to fix an hp dv7. About a month ago it would only accept the AC power cord if it was already plugged in and I was just turning it on. If A ever unplugged it and plugged it back in, it would no longer recognize it. As of a few days ago its not powering on at all with the AC, only with the bettery which is dead and wont charge. I just got a new power cord about 2 months ago. I've stripped the whole computer down and took the power connecter in the laptop apart and bent all the metal prongs so they have a better connection to the cord. Now when i plug it in the light blinks once and when i take it out it blinks once. If I put the battery back in, the charge light on the front blinks for about 5 mins then goes off. I'm at a loss for what could be wrong now. Any help would be appreciated.
