Fix a missing lock screen [webOS 3.0+]
This tip is only for devices running webOS 3.0 or higher
Just as we have seen a bug on webOS slider phones where you press the power button and it turns the phone on instead of giving you the standard lock screen with the "Drag up to unlock" padlock, the TouchPad has a similar bug that bypasses the lock screen. This bug will also prevent Exhibition Mode from launching when you put the device on a touchstone (or when you manually initiate Exhibition mode). While we are not sure what causes this problem, there is a quick fix for this. You just need to open up the "Phone & Video Calls" app and initiate a phone call. This can be an actual phone call (if you have a phone paired with the TouchPad over Bluetooth) or a Skype call, even including a "Sound Test" call with the automated Skype contact. Once you end the call, your lock screen and Exhibition Mode should return.
