If the screen on your TOSHIBA A215-S7422 fails to come on or goes black, it can cause quite a panic, since the monitor is one of the most expensive components. Some A215 models, however, have a problem with the basic input/output system (BIOS) -- a chip on the motherboard that controls the computer hardware -- that causes the PC to freeze and the screen to go blank. To fix a black screen on the TOSHIBA Satellite A215-S7422, perform some basic troubleshooting steps in Windows Vista, then upgrade the BIOS if the steps fail to fix the problem.

Skill level:
Moderately Easy


  1. 1

    Press any key on the keyboard to wake the computer. If the computer does not respond, hold down "Fn" and "F1" to check if the instant password feature is enabled. If a prompt appears, input the administrator's password and press "Enter."

  2. 2

    Hold down "Fn" and tap the "F7" key to increase screen brightness if no prompt appears.

  3. 3

    Hold down "Fn" and press "F5" to swap displays if the computer is hooked up to an external monitor. The TOSHIBA A215 has several options to cycle through, so it might take several tries to find the correct setting.

  4. 4

    Hold down the power button for 10 to 15 seconds to turn off the TOSHIBA. Remove the AC adaptor from the power jack.

  5. 5

    Close the lid and turn the TOSHIBA A215-S7422 onto its face. Release the battery lock and slide the accompanying tab to eject the battery from its compartment.

  6. 6

    Touch a bare metal surface to keep the battery safe from electrostatic discharge (ESD), then pull the battery out of its compartment.

  7. 7

    Leave the battery out of its bay for 15 minutes. Return the battery to its compartment and lock it in place.

  8. 8

    Turn the notebook over, open the lid, plug in the AC adaptor and press the power button to turn on the A215-S7422.

  9. 9

    Log in to the computer as an administrator, open a browser and go to TOSHIBA Support. Select the A215-S7422 from the "Product Support" link.

  10. 10

    Click "Downloads." Select your operating system, then click "BIOS." Click the BIOS link, then click "Download Now." Save the file to the desktop.

  11. 11

    Double-click the EXE file and follow the on-screen instructions to auto-update the BIOS on the A215-S7422. The computer will automatically restart when the update is complete.

Tips and warnings

  • If the above steps do not fix the blank screen, the display may need to be replaced, or the video adaptor on the motherboard could be defective.
  • If you've updated the BIOS on the computer in the past, click "Start" and go to "All Programs," "TOSHIBA," "Utilities," "TOSHIBA HWSetup." Check the version on the "General" tab and compare it to the version on the website. If the versions match, you do not need to upgrade your BIOS.
  • If the administrator login fails when pressing "Fn" and "F1," contact TOSHIBA for more assistance.
