My DELL OPTIPLEX 755 boots up but no display. Indicator 1, 3 & 4 lights up green what could be the problem?
Your video subsystem has failed. Code LEDs 1,3,4 indicate system activity preceding video initialization. If you are using an add in card, check to make sure that it is seated properly. If it still does not work after reseating then the card may have gone bad. Also check that the adapter cables are properly plugged in. Try connecting to the on-board video and see if you get any display (you will have to remove the add-in card). If you are using the on-board video then you have a failure on the board and would need to replace the motherboard. Good Luck.
Dell optiplex 740 vs dell optiplex 745?
I am looking at purchasing one of these 2 computers. In my opinion there isn't much of a difference except in CPU. The 740 has a Pentium D or Pentium HT (which is better?) and the 745 has a Core2duo. Is there much of a difference between these 2 computers? Also do these computers use a lot of power? I am trying to keep the power bill down. Which is better a laptop or desktop? Thanks
How can I fix my Epson L210 printer, which is not printing ink despite the ink tanks are all filled with enough ink?
There are two possibilities:If the ink level showed on printer manager panel is full, then the problem should exist on the ink nozzle. That is to say, the ink nozzle of the printhead is blocked. Please clean it with cleaning fluid.If the ink level showed on printer manager panel is low or empty, then the problem should exist on the ink recognition function of the printer. Please contact the printer reseller for maintenance.Please kindly note that even the problem only happen to one specific color, the printer will not print at all.
