A very dim screen is an indicator that the screen inverter or the screen itself is going out. Start by checking the screen connections, they sometimes work loose. If the connections are good, then it's the inverter or screen and will need to be replaced.

Dell Latitude e5410...brightness changes from dim to bright on it's own. Not using battery powered. What could be going on?


You could be manually brighting it. Hitting the FN and UP arrow and Down Arrows Dim and brightens the screen, But if it does it on it own check your settings on Power Options in the control panel and on the left you will see Create a power plan sure setting are set to Balanced then click on next. You now get to pick to dim it when plugged in or on battery. I change it to "Never" becuase i like to see the screen brighter save your setting and your done.

I cracked my screen a while back and started using a monitor for my screen, which i had no problems with what so ever. I bought a monitor off someone, as they were seeing which monitor was best they were...


I'd check the ext. monitor port for bent pins, or possibly even a broken pin - if it's bent you can probably straighten it out (very carefully using tweezers),; if it's broken then it's toast - that's pobably why you ain't getting a signal on the external.

The 2nd hand screen is either no good or improperly installed or it might not be compatible (I've seen incompatible screens where the brightness control adjustments are just ... reversed - i.e. dim means brighter, and brighter means dimmer). eBay is a pretty good source for these things (used, original stuff) so I'd check there if I still have access to the original screen (the cracked one). Check under Samsung N130 and you should see plenty of screens that are being parted out...

How do you make the lighting on the screen brighter without the charger in ?


The screen will automatically dim slightly when it is on battery power, this is to conserve battery power. For maximum brightness connect the power adapter into the laptop.
On the Thinkpad laptops you can adjust the brightness by pressing and holding down the blue Fn key plus the Home key to brighten or the End key to dim the screen.

Screen gets dim at times.


Backlight is going bad.
Either bulb or whole LCD needs replacement.
But, first start with new/good Inverter Board.
