My Toshiba Satellite L455D-S5976 Laptop suddenly won't turn on this morning. It was working fine all day yesterday. It was mainly used for my Photoshop and Dreamweaver projects so there's no abuse there. I was playing an online game at lowest setting last night for around 5 hours before turning it off. I always had it plugged in all the time while using it. The Laptop flashes light indicating it was plugged in for one second then turns off. I have no other power adapter to test if it's the problem and I don't have a multi tester either to confirm if the laptop is getting the right amount of power from the adapter.

The warranty is expired as it was bought two years ago.

Things I already did:

Remove the battery, press the power for a minute and putting it back on.

Remove the battery and directly plug-in the power adapter.

Reset the RAM modules.

I would like to try to fix it myself first before sending it to a professional.

Anybody have similar problems or suggestions for a fix?

To isolate possible problem, plugging into a different power adapter can provide is the possible problem.

This gives us an idea of whether the power cable is bad about something else inside, like hardware failure. If laptop won't turn on, there's a big chance that it's a problem with Video Card and other components inside. Testing these steps will save you bucks because if you bring this to the computer expert, you might pay for the service they've provided but the simple solution is the power cable.

I suspect, since you've used it for 5 hours, the battery might run out. So take time to charge the battery because this might be the simple issue and can be solved by a simple solution.

Play around with the settings and adjust the monitor's color in the menu bar, this might solve the problem.

When you tried turning the computer on, did any of the LED lights on the computer’s body turn on or not at all? If they did turn on, this may just be a problem with your display or it could be a video card problem. The LED lights can also be used to determine which hardware failed as these are usually used to give you an error code pointing to the problem.

If there are no LED lights turning on however, and both the battery and charger can’t turn the computer on, you need to have the motherboard replaced. It would be cheaper to just buy a new motherboard or a new computer compared to isolating the part on the motherboard that failed.
