Answer 1

Check the power cord. A friend of mine was complaining her CQ60 wouldn't charge unless she jiggled the plug connection at the laptop. She thought it was the battery and ordered another one but found it was still not charging correctly. I looked at it and confirmed that the cord had one loose connection at the barrel plug. The cord was easily fixed by slicing a concentric circle around the plug about a 1/2 inch down from the rubber end and then peeling it off to expose the two wires. I found one wire broken from the solder joint and thus not getting a good connection. I drilled a small hole into the metal barrel to make a better contact and then resoldered the wire into the hole. I then super glued the concentric section I sliced off and then put a piece of 1/2" 2:1 heat shrink tubing ($1.25 on eBay) around it and shrank it around the repair. It's fixed and due to the black heat shrink tubing, you can barely see it was repaired. Hope this helps!
