how do you take apart an Acer eMachine E630????
my mates usb ports are ****ed, the (male) connection on the usb ports has being some how pushed into the laptop, and how the usb ports don't work at all, and I want to take the laptop apart and push them back into place and see if it works... I tried taking it apart already, by taking out all the screws i could get at including those under hard drive and cpu, but something wasn't letting it come apart easy, and I didn't want to force it, coz I didn't want to break it... if anyone could tell me how to do it, it would be sound, Thanks dave

come on, i taught i've had a response by now..... anyone know where i can find out????
