Computer will not turn on. Power supply shows flashing green.

Laptops are so integrated that usually a system failure that involves power issues such as in your case where you cant get it turn on with anything on the screen mean the mainboard (motherboard) is damaged. This usually leads to buying a new laptop or paying for the board to be replaced which usually costs as much as the laptop.

hello, make sure nothing has come unplugged and that none of the buttons are stuck on. With that said if this is an older pc, your power supply inside the case might have went out. power supplies go out quite often, replacing them is not to bad just make sure you have the correct physical and power size. Also verify that it has the connectors for that particular motherboard.
hope this helps

It seems like it that you have a faulty power supply. Also the motherboard may be damged aswell, But most probably you can fix your PC by changing the power supply.

On the back of the Power Supply there should be a Green LED, When you power it on if it is flashing, this means that the Power Supply is dead and you need to replace it.

Sounds like the power supply or the motherboard. If you have another computer available, you can test the power supply. Just "borrow" the power supply from the other computer. If it still won't come on, then the motherboard might be bad and you'll need replacement.

If you swap the power supply and the motherboard is bad, you will not hurt the working power supply. The motherboard is already dead and won't feed back to the working power supply.

Also, if you have flashed your BIOS recently and it has not completed successfully, you might have a dead motherboard and you will need to replace it. You would know if you flashed or updated your BIOS chip.

Hope this helps!

the green edges you desrcibe suggest a low HT supply from the power supply, and now its likley the power supply has failed completely and will need to be replaced
