I apologize for refreshing the topic, but I have a problem, and I can't find the solution, and this topic seems to be the right one to ask.
I've bought used AcerH6500, and some menu options are inactive. One of the inactive options is "ECO Mode" it is set to OFF (so normal mode is ON) and I can't change it. The option in menu is in grey colour, and I can't even choose it, it just skips it - typically for inactive options (doesn't matter if I turn that menu using "MENU" button, or that "e" button, always inactive). Do you have any idea what might have caused it, and what can I do to activate the option?
Thank you in advance for any help.
