Hi, Welcome to JustAnswer
Which tablet you are using ?
Can you send me screenshot or picture of the error message ?
I mean image of the opening page
yes right, I can't connect to your machine remotely. You must have got message from JustAnswer for remote assistance. Please Ignore it for now.
Please try this :-
1. Plug the power adapter into the Tablet
2. With the adapter plugged in, Hold down the power button for 20 seconds
3. Disconnect the power adapter from the Tablet and press the power button for 20 seconds.
4. Reconnect the power adapter and turn on the Tablet. It should power up just fine.
See if this works for you :-
plug in the power
using a straightened paper clip, insert it into the hole on the bottom edge of the tablet to the left of the docking port until you feel it click
hold for 20 seconds
unplug power cable
insert clip again and hold for 20 seconds
plug power back in
press top power button
you must be seeing something like this :-
Select Boot Mode:
[VOLUME_UP to select. VOLUME_DOWN is OK.]
[Fastboot Mode] <<==
=> FASTBOOT mode...
You must use ADB command:
install ADB and drivers:
Then in CMD windows, go to ADB directory. Then, type "ADB reboot"

You need to follow steps as shown in this video "-
This is sure shot method .This works on all tablets. If it doesn't works then it is a hardware issue.
