After I trashed a bunch of stuff cleaning my 10v for selling, things went bad. The battery is no longer recognized and sound does not work, light is flashing rapidly. At first I thought it was the charger, bought a new one and it boots fine with or without the battery but it still won't charge. Research mentions BIOS? Sound worked fine before also. I did not do the original OS 10.5 install, bought it off bay over 2 years ago, and can't find the seller. I do have retail OS 10.5 and 10.6 if I need to do a fresh install, but would like to get this one straightened out if possible. Any help will be appreciated, and this is coming from a non hacker, but I have tried to digest all the guides in the forum.
