Hello there,
I have a new problem with a tablet computer i purchased a while back. It is now turning on by itself. It did not appear to do this when new, but no new software was downloaded for it over the past say couple months yet it started about three weeks ago.
There are two ways to "shut it off", one way is to put it into 'sleep' mode, the other way is to do a full power down. In sleep mode, the cpu i think still runs at least now and then, and if you press the power button quickly the unit will turn on completely in less than a second. The other way is to do a full power down. When that is done, to turn it back on you have to push and hold the power button for about 2 seconds, and then it boots up. Booting takes about 10 to 15 seconds.
To do a full power down, you have to press the power button for 2 seconds rather than quickly, and then you get a message on screen that asks if you really want to power down, and you press "OK" to fully power down. It takes a few seconds, then turns off.
During the full power down, the CPU is off and there is little power consumed and the battery should last for months like this. During sleep, there is much more power consumed and the battery will run down in a week. So if the tablet is not to be used for a while, it is best to do a full power down.
This is where the problem starts. I do a full power down, which i have always done in the past, and after some time later like maybe 48 hours or so, the table is seen with it's screen fully lit up and running! No buttons pressed ever.
At first i thought maybe i bumped it and the power button got hit and so that is how it turned on and i didnt realize it. But recently i built a specially designed case that would house the tablet in such a way that the button could not be depressed even if the case was bumped or rattled or even dropped. That was easily done by using plastic tabs that stick out in places where the power button is not located so that if the tablet slides to the right the case itself will hit the tabs and therefore the button can not be depressed. I tested it several times in many different positions to make sure the button could not get pressed, and it is very very clear that it can not be pressed without removing the entire tablet from the case. The case has a snap shut lid that can not open without considerable force.
Also, the case is made of semi clear plastic so it is easy to see if the screen is lit up. If it is lit up, the device is turned on.
So what is happening is the device is turning on by itself now. There's no way anymore that the button can get pressed, so it has to be being turned on by an external signal or by some internal self generated signal. There's no other possibility now with the new case in effect.
So the question is, does anyone know what might cause this or did they ever see this before?
I have read that there is anther device that 'turns itself on' but i think that is when it is in 'sleep' mode not fully powered down, and that one is a Toshiba. The one i have is an iView Tablet.
Any ideas?
