Default Fujitsu Lifebook NH570 not powering up

Got Lifebook NH570 here that won't power up. Customer said that it just shut down and wouldn't power up after that.

When I push power button, light indicating that battery is full lights up, so I assume button isn't broken. Charger is working and dc jack isn't broken. Don't have extra battery to try out.

I tried basic unplug charger, battery out, push the button for a while, plug charger. Nothing. Tried re-seating ram, hard drive, every cable. Nothing.

Don't have much experience about board level fixing of laptops, so won't go there.

Customer wasn't sure if laptop still has warranty left. If it does have warranty left, just send it to manufacturer.
If it doesn't, I think I'm safe to assume that motherboard is broken and try to find new one.

Any tips to try before making verdict?

Default check power cord.

I was trouble shooting a toshiba the other day. it would turn on for about 3 secs then just shut down. I tried reseating everything. I was was sure the mboard was going bad. I compared my cord output wattage and voltage and + - sure enough powered right up. I charged his battery for him and ordered him a new cord. the cord cost like $9 on ebay.
