I have been facing this problem many times, sometimes the machine hang and need to be reseted, when the machine been reset, it it has quite a number of the panel button light lit, but once boot into the Windows NT environment, the button light should be off, but they still lit, the during the self test, it encounter this problem
And sometimes we open up the panel on the LCD screen, and check the cable connection, it may work again, other times, it just leave it until the next day, it work again.... Anybody know why? Is it the connection? Is it the computer problem? The machine is not located in clean environment, it at a open space, do u think the humidity could affect the PC or maybe it is overheated? Does anybody here put the machine inside a clean air-conditioned environment? For your information, I am living in a tropical country.
