I have a Dell 1135n printer. I know it is old and out of warrenty, but it work fine, untill a few months ago, when EVERY time I turn it on, it asks me for the time and date. I enter innformation it wants and then it works fine. But if I turn the mains power off and then later turn it back on, it has forgotten the date and time and I have to input it agian. Not a major problem, just anoying. Sounds like a battery may have gone flat, but I cannot find any information about a battery in this device. I can change a battery myself, but just need to find out where to start undoing screws to find it.

Any help on where the battery is would be appreciated.

If there is no battery, any other help as to what could be wrong would be appreciated. Thanks,
