If that does not work, reboot again and press the next listed key immediately after the display becomes active.After you get to the boot menu, step five involves locating the bootable Crafted Flash USB device.The entire print head is moved horizontally in order to print a line of text, striking the paper several times to produce a matrix for each character.
Typically, the BIOS Driver is located on a chip on the computer motherboard and does a quick check-up of all hardware.
A dot matrix print head consists of a series of metal pins arranged in a vertical row.
Each pin is attached to some sort of actuator, a solenoid in the case of Centronics, which can pull the pin forward to strike a ribbon and the paper.
But I figured out what the problem was: it is in the BIOS settings, for USB charging when off, and allow laptop to go into low power mode when off.
These settings were ENABLED on mine the day the problems started, and the problems stopped when I disabled them. If you have the same problem, try changing these settings in the BIOS. I have an ASUS UX32A, but am guessing that this problem is common to their Zenbooks.
