Power connection to the motherboard very loose. Because of loose connection, I lost OS and all “F” options don’t work. Screen lights up and battery charges. I need to know how to disassemble laptop in order to attempt repairs. Where can I get a manual or instructions to repair laptop? Thank You, Michael

@teckman3 download the maintenance manual from here. It will show you how to disassemble your HP.

Here are some guides on how to repair things and you might be able to get some information out of this. I’m personally a Mac guy and I don’t know much about PC’s so that’s about as much as I can dig up for now.
