just to update I played around with it alittle and this is a slight fix that does indeed have drawbacks. You can set u lock settings to 0 mins and it will work, of course the drawback is when the backlight goes off, u will be putting in ur password again. hope this helps.

Edit: after playing with it more, it only works if u manually shut off, and it seems to only work this first time. Im not sure if there is a way around this, and I may report to MS to see if we can get a fix. This really needs to be.
