Hi,
Please do try these troubleshooting steps that may help.
- First do a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- Next to try is to reseat the RAM's, remove them all for couple of seconds then put them back in making sure they are all seated properly.
- If these will not work, you'll need to take the HDD off the laptop then boot it up.
- If the laptop will get pass the Innovation splash screen and goes up to a black screen with an error about missing boot device that could mean that the HDD is faulty.
- But if the laptop will still get stuck on the same Innovation Splash screen, try loading into BIOS and set it to its default by pressing F9.
- If all these will not work I would suggest contacing Toshiba for a repair.
