hello, i'm very new to this site, but i have been working with computers for some time. i recently started doing little jobs on the side, and well now i've run into something that is just mind boggling. some guy gave me his gateway nv54 laptop with windows 7 home premium and he wanted to know if his smashed headphone jack could be repaired, and i decided to take a look. i have opened up many laptops before and have never had a problem. HOWEVER i saw that the jack was beyond anything i could repair, unless replace, which he did not want, so i put it back together. the guy turns his laptop on, and his left click on his touch pad wasn't working. immediately i assumed that maybe i had not lodged the ribbon in correctly, so i opened it back up and all seemed to be fine. still, it did not work. so i said, "hey, leave this with me over night, and i'll have it taken care of" so after much research and even re-installing windows 7, the touchpad does not work at all anymore, and now the battery won't charge and it's all just this horrible nightmare now! his laptop will work when plugged in and NO BATTERY. if the battery is in, then it's a no go. but with the battery out, it will turn on, but not load up windows, however it will stay running in the bios. WTF!? i'm really stressing out here, and the owner of the laptop is furious, someone please help me!
