Hi Aiden,
Try unplugging your laptop and holding the power button down for 10 seconds until you see all the lights go off. Then plug your laptop back in and try powering on.
If this does not work, you can try opening your laptop up (unplug it first, remove the screws) and remove the backup batteries. Some laptops have a CMOS battery or another battery inside that may need to be detached from the motherboard.
If you do not have experience with this, you should go to a place and hire a professional.
