Having problems with your Dell Inspiron 6400 Notebook ?

Lcd problem I am getting the opposite to most people. My laptop will run fine without the plug-in. It will charge with the plug in. But when I try and use the plug-in and run my laptop (for better light and longer use) it turns my screen black. If I disconnect the plug-in battery and close the lid on the laptop, my screen will come back and I am good to go. Can someone help me. tks fahim


Answers :

Try the power options. You have different settings for power and for battery. Make sure the with power settings is set to never turn off the monitor.
Hi,
The problem is the inverter cable or the inverter itself.
This is because you have indicated that when you close and open the lid the display returns. I would edge on the fact that the plugs to the inverter are loose but here is the fix>>>>>>
If you have any warranty left on the laptop then i recommend you take advantage of that and send it in for repair, or you can deal with this 2 ways.
Fix the problem yourself.
Remove the screen bezel (plastic screen surround), this will\015\012reveal the whole screen. At the bottom of the screen you will see an\015\012elongated piece of circuit board with wires coming from either end\015\012covered by frosted plastic.
That is the inverter, check the connections on the inverter and power the laptop up to check the display, to remove it\015\012gently pull the plugs from each end and remove the screw from the\015\012middle and pull the board away.
Look at the inverter for a copper coil, if you\015\012re-solder the solder points around the coil you may find it works again\015\012as components that suffer from extreme heat the solder joints dry\015\012causing bad connections, re-floating the solder solves the problem in\015\01290% of cases.

Take the laptop for repair.
In\015\012this case all you have to do is source a reputable PC repair store and\015\012take it in for them to fix. (it should be fairly inexpensive).



Good luck.
