If, after pressing the ON/OFF button, the machine's screen remains black and the computer does not start up automatically, one possible reason is that the computer's BIOS battery needs to be replaced.
Please contact us so that the battery can be replaced and the necessary settings can be made.
The computer can be started by manually pressing the switch directly on the computer in order to be able to work with the machine until after the BIOS battery has been replaced the computer starts up again automatically when the ON/OFF button is pressed.
