i am working on an inspiron n7110 that was dropped. now, the batter doesn't charge and the dvd player is not working. when you put a cd on, the icon spins, but nothing happens. if you click on it, it says insert a cd. when it boots, a window pops up and it says that it cannot identify the charger and the battery is not being charged.

the only thing i know about it is a friend said it was dropped, and there is a chip in the cover to the left of the mouse, on the part that comes off so the motherboard is accessible. i had the whole thing completely apart and could find no physical damage at all, reseated all the connections, inspected for signs of damage and found nothing. i thought it may be software related, so i backed everything up and reloaded the os using the factory image and it did nothing except reset the computer. my guess would be motherboard damage that is invisible, but i would hate to advise the customer to pay $200 for a new one and it didn't fix it. anyone have any other ideas or troubleshooting steps i can use to narrow it down further? not sure if it matters, but it is windows 7 home premium, factory image.

Dell chargers often have a central 3rd connector that 'tells' the laptop it's a genuine Dell charger so if it's the charger that came with the laptop I would check that it's not bent or broken off.

Could also be the power socket that got damaged and that's where the bad connection is. Some have a separate power board you can change, not sure about that model though.

The DVD drive could have been damaged in the fall, easiest thing to do is try a known working one, they are usually the same apart from the faceplate which doesn't matter for a test and maybe an adapter on the internal connector you would have to swap over.

EDIT : it seems the power connector on the laptop has a lead that goes to a motherboard connector so it should be easy to replace if necessary. It's on P.112 of the Service manual - download link :- ftp://ftp.dell.com/Manuals/all-prod...p/inspiron-17r-n7110_Service Manual_en-us.pdf

thanx for the quick response, that has to be it. i didn't see any physical damage. that would be why the charger isn't recognized.

You're welcome. If that doesn't fix it it would be best if you start a new thread since this is one is marked solved now, hope you don't have to though.
