Try resetting it by holding down the power button for 10 seconds.that would shut it down. Restart then try logging in. Try to factory reset using the combination buttons as listed below
look for a tiny reset pinhole along the case it may reset the tablet too All RESETTING Ways Below Holding Down Certain Sequence of Keys or Buttons will put Most Tablets or Android Phones in Service mode to Factory Restore to New.

Not sure about specifics on toshiba tablets, but wanted to suggest that on other tablets you can hold the up volume(sometimes others its volume down) and power button at sane time for about 10+seconds and a menu will pop up for a rebooting, safe mode, and factory restart(which erases and reboots from scratch) worth a shot.. Yet, be careful what you select if it works.. Don't want you to erase stuff if you don't want to.... And btw most tablets have a little pin size hole either under the camera lense or on side that something like a paper clip can push a reset button... But don't think that helps with password.. Just if it freezes up and won't shut down... Good luck.. Sorry if this doesn't help...

Shut it down by simultaneously:

Holding down power button
Holding down volume down
Holding down Home button

For 10 seconds.

After shut down, restart it.

Once the tablet has shut down, press and hold the Volume Up and Power buttons simultaneously until the Samsung logo appears. The Samsung Galaxy Tab will boot into ASR (Android System Recovery) mode. 3. Use the Volume rocker to highlight the 'wipe cache partition' option and the Power button to select it.15 Sep 2015

see if this helps you out.

Shut down the tablet. Then press and hold power button and volume up button until the boot menu is loaded. Then select HDD recovery. Now tap Yes, select troubleshoot, select Reset your PC and follow the instruction on the screen to finish the procedure

The solution is a factory reset....I know you have done this but did you follow these instructions?

1.Make sure the tablet is off and not in standby.
2.Hold down the 'Volume Up' and 'Power' buttons simultaneously until the two Android icons appear.
3.Use the volume buttons to select the white box on the right.
4.Once selected, press the power button.
5.Use the volume buttons to select 'wipe cache partition' and then press the power button.
6.Select 'Yes' and press the power button.
7.Use the volume buttons to select 'wipe data/factory reset' and then press the power button.
8.Select 'Yes' and press the power button.
9.The tablet will now reset.

Try holding power and both volumes if it reboots normally try again but let go of power when the Android pops up

Try using a paperclip to reset it on the back, hold it in for 5 seconds, if that doesnt work:
Turn the tablet all the way off, press and hold the VOL - and power at the same time for 8 to 9 seconds, it will show a green android guy with a system recovery menu. Use vol - to go down to Wipe Data/Factory Reset, press the power button to select it, go down to 'yes' to confirm, press the power button to select it, it will wipe the tablet, you then press the power button on 'reboot system'.
