Video Tutorial.
If it says "Too many pattern attempts...",
or not working / frozen Android system,
or you want to erase all data (factory settings / restore).
This video shows how to unlock Acer tablet.

For "Too many patterns attempts...", try to log-in with your Google account.
If you have a problem with your username or password, you can fix this using another computer.
IMPORTANT: Because you don't have an access to the menu, you can only use a WiFi network that you have used before (you can't make a new wireless connection). And if the wireless was turned off when you last used the tablet, you are not lucky.

Next step - if you can't log-in with your Google account, you can try with ADB (Android Debug Bridge).
This is a command line tool that lets you communicate with a connected Android-powered device.
You can unlock it using ADB or turn on the Wi-Fi or mobile networks and unlock it using your Google account.
Also, you can use this method only if you have USB debugging turned on. This option is turned off by default.

Finally,if nothing works, only factory reset can give you access to your android device.
If your device is synchronized with your Google account you can restore it after that. Otherwise the device will be like brand new (software-wise).
