laptop won't boot

[jaxon.duncn1]

so my laptop i have been working on died but when i plugged it back in it wouldn't boot up so i reseated the cpu, ram, hard drive and cleaned it but nothing seems to work, the fans spin up and you can hear the hard drive but after 5 or 6 seconds it completely shuts off there are no beeps or anything i have been trying everything but nothing works any ideas?

First (if possible) reset the CMOS. The manual should have instructions on doing so. That should help booting if a component has not failed.

A new power supply brick or battery would be my next solution.
