Apart from not being able to use Windows 8 (though it seems I managed to stop Windows 10 from sending info to Microsoft and the NSA, at least for now), I have some things that bug me while using it.
1. I have not found a way to remap the mouse buttons. Buttons on the left side are the "left" mouse button and the buttons on the right side are the "right" mouse button. What I would like to do is to, say, map R2 to be "left" mouse button and "R1" to be right, so I could control the mouse with one hand. Or, map L2 to be "right" mouse button and "L1" to be left. The way it is now, I have to put both my index fingers on those buttons to use the mouse.
2. If the device is turned off, but plugged in, when I turn it on, it just displays the battery status and turns off. I have to disconnect the charger, turn the device on, wait for Windows to start booting and then plug it back in.
3. When the battery is fully charged, the devices seems unable to detect that the charger is plugged in. At least Windows does not display it or change the power policy to "plugged in". What actually bugs me about this is that I want to make Windows never turn the screen off when plugged in (the wall outlet won't discharge), but the setting is only respected when the battery is not full.
4. This is probably related to the charger stuff, but sometimes Windows goes to standby or hibernate (fan not spinning) and the device refuses to turn on (didn't try unplugging first though). Pressing any buttons does not do anything. Holding the power button (longer than I need to hold it to turn on) makes the blue LED flash, after that pressing and holding the power button makes it turn on and boot up (losing the state).
Maybe there are new drives or a BIOS update that fixes these things? Have any of you found a way to fix this?
