No Booting and blinking charging (sometimes)

I have had this laptop for a decade or so now and I would like to keep it running as a secondary machine, I recently tried turning it on, and it just wouldn't, plugging in to the wall indicates that it is charging but as soon as it turns on (the power LED turns blue) along with the Bluetooth indicator, it instantly turns off again, plugging it in without the battery just leads to nothing at all happening, I once let it charge overnight, it booted and the fan spun up, for all of 3 seconds and then turned itself off again, any help would be welcome at this point, I would rather not go to a repair shop unless I have to, as I would like to keep it running off of my own work.
