Question about HP Pavilion dv7-1240us Notebook
Was the new one that you purchased from HP? If so, then did the model numbers of the old one match the new one you bought? If the new one isn't an HP power supply, then that could be the reason why it won't charge your battery. Some of the "after market" power supplies will be enough to run the computer, but they aren't all able to charge the battery. It could also be the DC Jack on the motherboard that has gone bad. If you are not familiar with de-soldering a component from a motherboard, then you may want to think twice before attempting it. You will have to get the exact jack that goes to your motherboard, de-solder the old jack, & solder in the new one. Trust me, de-soldering and removing an old jack isn't always as easy as it sounds. You will have to completely disassemble your laptop to do that too, so be sure to keep track of all the little screws and which screws go where.
