Question about Dell Inspiron 8200 Latitude C840 Laptop Keyboard03J247 CD-ROM Drive

1 Answer

Screen switches on and off and on and off etc, or just freezes

Hi,
I have a Dell inspiron 8200 laptop since 2001. It has 512 Ram and 40 Giga harddrive. Last november, the screen randomly started switching between on and off about every second. Sometimes it would just freeze completely.
The only solution is to switch the computer off.

I have tried various fixes and don t know what to do anymore:
in safe mode, I have never had any problems.
I have run the Dell diagnostics Cd (even the slow one) and that passed all the tests.
I thought it may be the batteries/ power related.
I have checked antiviruses with avira.
I even formatted and reinstalled everything, and updated the drivers. I thought that had fixed the problem, because after that it was only freezing some times, but was not having the screen on -off switch anymore.
But the switch on and off and on etc thing started again last night, and I now just don t know what to do anymore.

Do you have an idea what it could be?

Thanks and Regards,

John-Frederick

MY LAPTOP DELL INSPIRON 8200 SCREEN LIGHT KEEPS BLINKING, WHAT COULD BE THE PROBLEM??


It can be 2 things: Or the screen is dying, or the graphics card is dying. Try to start up with an external screen and see if it still blinks. When its still blinking on the external screen, your graphics card is dying, if the external screen shows no issue, then your screen is dying.

Dell Inspiron 8200 ATI Mobility Radeon 9000 Green Screen Problem


Try connecting an external monitor to the laptop. After your computer is attached to an external monitor, press the <Fn> key and the <F8> (CRT, LCD) key to switch the video image to the display. If the external monitor works, the computer display or video controller may be defective.

Dropped laptop


Press and hold the <Fn> key while powering the system on. This will run the Dell Diagnostics. Another more intense diagnostic program is located on a Dell CD that you should have received with your laptop. Look for one that has “Diagnostics and utilities” listed under the “Contents”. You will have to boot from that CD disk. To do this, power on your laptop and tap the <F12> key to bring you to the “One time boot menu”. Insert the CD and then select CD/DVD drive and hit <Enter> key. Select the “Run the 32 Bit Dell Diagnostics”.

My laptop screen keeps on switching on and off and on and off and on....


The problem your having appears to be with your video circuit. Depending on your model's options this would consist of 1) LDC panel display, 2) video card or on board video controller, 3) LCD ribbon cable. If your laptop has an external video adaptor port, connect it to an external monitor and see if the problem occurrs. If the problem happens on the external monitor then your laptop LCD display panel is probably OK. If this is the case, you'll need to diagnose the problem further or take it to a repair shop. The reason it seems to work in safe mode is that the video circuit is not being fully utilized, ie.. no wallpaper, screen saver, etc..
