XPS 13 won’t turn at all ALL, blinks white/orange

I pressed the power button today but it did not turn on. It was working fine in the morning and was fully charged. So now I press the power button, keyboard light flashes on, battery light blinks white and then orange, keyboard lights turn off, blinking stops and it remains black. HELP please. No idea what to do. Should I bother buying a screwdriver and try troubleshooting myself? phone lines are closed and shops are closed now, would have to try tomorrow. I already bought a new adaptor to see if it was maybe a charging problem but it’s not. It’s clearly charging (as per the white light) but just won’t turn on!! So frustrated
