On the keyboard pressing alt+ctrl+del. Your mileage may vary as you're just as likely to depress the power button until the system shuts off. Can you please pass on your laptop's make/model/SKU? You might want to go into BIOS and see if the BOOT device order is, er, in order. I'm assuming you swapped the HDD out for an SSD?
