Hello, has anyone had problems with the backlight not coming on often with the 3800 series IPAQs? Mine will only come on when fully charged but after i use it a few minutes or when i turn it on, the backlight will not come on at all even when the screen is being touched. In the system configs of the IPAQ, the backlight is adjusted to be full brightness with normal battery and external battery (external not on it though). Let me know if there is anything i can do. thanks.
