Hey there! Because of your particular situation, you may have to perform a hard reset, as it seems the update process didn't complete successfully, leaving your tablet with a corrupt operating system. Before attempting this, please have the tablet charged up all the way so that the reset can complete fully without interruptions.
How to Hard Reset LENOVO A5500 (A8-50) with Hardware Button key:

Choose: Reset Device, or Wipe data, or Clear eMMC, until you find an option that works for you
Doing the hard reset will clean all installed applications and all data will be lost or cleared while Resetting LENOVO A5500 (A8-50)
Try a local phone repair shop, when you can't find a Lenovo certified repair centre. First ask them what it will cost you, then decide if you think it is worth repairing. Don't leave it without knowing what they will ask. A screen alone can be very expensive.
Try to slide and hold the on switch until after the power light blinks three times (should happen after a little more than 5 seconds). Release the switch after the blinks and the Kindle should start up.
This is only necessary if the Kindle was switched off by the same method before, or if the battery was completely drained. A short nudge of the power switch merely puts it in and out of a power-saving sleep mode, the prolonged hold really cuts / reinstates power.
Either your laptop had gone to sleep or hibernate mode. You can set the timers under Power Options on the Control Panel for the laptop to go on sleep mode or hibernate mode if idle for span of time.
You can wake up the laptop by touching the touchpad, pressing a key or pressing the power button.
However, if above options will not work, the only option for you is to press and hold the power button for at least 5 seconds to completely turn off the unit. Try to power on the computer if it will boot up okay.
***ADDITIONAL NOTES FOR CASE TO CASE BASIS**
If you still get black screen, remove the battery and the ac adapter (charger) then press the power button for at least 20 seconds to discharge power in the motherboard. You can now reinsert the battery and power on the system normally.
***NOTE: If the computer will not boot up, the LCD or the motherboard might have failed.
