Screen Keeps dimming and contrast function does not work

We have a samsung np r40 plus, its not very old and we have had this problem since getting the laptop...the screen dims and we cannot see much of the screen sometimes its fine and sometimes not...we have tried changing the optimise for performance etc and have also tested that its not as a result of the battery running out....any ideas what might be wrong or what setting needs changing?

Hi,
This is possibly, a loose cable or the screens inverter board is overheating. the inverter is similar to a booster in a flourescant light fitting. which converts power from DC To AC and boosts up the panels Light Tube. CFL if it,s faulty or overheating. this will cause the panel to dim.
also check the plunger at the underside of the screen, isn,t sticking down. designed to cut off the panel when the lid is closed. Finally some model laptops, only boost the brightness running on A/C Power. the battery would run-out fast with screen at full brightness. if theres an fn key on the keyboard, press fn and the brightness button to adjust screen brightness.

Samsung r40 reset to factory settings


hello there Start by pressing F4 when the BIOS "Samsung" screen is showing. This will allow you to restore the original operating system from the recovery partition, if is there. (Also try the other Fn keys - F6 and F8 may do something).

Otherwise you will need to beg, borrow or buy an XP Home installation CD and use that for a new installation. You can use the Samsung key on the bottom to activate it. You can get the R40 drivers from SamsungPC.

My TI 84's screen went black.


One possible solution is to dim the screen contrast. To do this, turn the calculator on press the 2nd key, then the up arrow. If contrast has been darkened, this should work. To darken the screen if you get it too light, you do the same, but use the down arrow. Hope this helps.

The display screen has turned black


When you connected the external monitor thto the laptop did it display?

If so then you have to reset the monitor port. Hold down the function key and find the FKEY that shows a picture of a monitor. Press that until you get the laptop screen back.

Typical use is:
  • 1 press = external monitor
  • 2 presses = laptop and dual monitor
  • 3 presses = just the laptop screen
