Laptop doesn`t turniej on

So it`s actually 2540p but it wasn`t an option, anyway, i know that the laptop is long past it`s lifetime but i`d really like to see how long it can go for. Long story short, the battery is long dead at this point and the laptop was working on AC only for the past few months, and today it just turned off during some a bit more intensive cpu task and won`t turn back on. With the battery in and power plugged in it does a short white and then constant orange blinks which afaik means low power onmaster battery. With the battery out and ac in, it gives a short white blink and goes quiet, then after pressing the power button it gives 8 orange blinks and then nothing. I`m honestly not sure what i can do at this point
