Compaq F755 US laptop needs motherboard? (delete, problems, power)

[movintime]

I think. I searched ebay but am looking to get low as I can. We think it is motherboard NOT power button cir. board, as it won't stay on but a sec when turned on. I'm lost on this. I want to fix it & save on a new one but I'm hearing pros/cons. Thank you again guys.

If this breaks TOS I'm sorry, as I've not read it all yet. But please delete if so. Thanks.

Does anyone know much about these? I'm having problems finding one & think getting a second one to use for parts may be only way to go.
