Having problems with your Dell Inspiron 1420 Laptop ?

Cant figure out why my new lcd screen stays blue and dosen't show anything on it ... my laptop is working fine because i can see everything on a external monitor. Is there maybe a problem with inverter? When i switch displays the laptop screen goes black like it normally would,when both screens are on the laptop screen comes on blue but nothing appears on screen and the blue is faint,all the while windows and everything else works perfectly on eternal screen. I am lost please help?

Hi,

This is known as " Blue Screen Of Death Error ". I really appreciate this time, we can easily understand your problem that Windows work perfectly on eternal screen But not on your laptop screen.

This is actually not a software bug because if this would has been a software bug, you would not be able to view windows on the external monitor as well. This is a Hardware Problem.

It's my advise that if your laptop might be still under the manufacturer warranty. If it is still\015\012under warranty, take it or ship it to Toshiba authorized repair center\015\012and let them fix the problem.
\015\012I would test the memory first.\015\012The laptop has dynamically allocated shared graphics memory; it has no\015\012dedicated memory and uses part of the main memory for video purposes. I\015\012guess if the main memory is going bad, you can get an error message\015\012related to the graphic card. For memory test I usually use Memtest86+\015\012utility, it’s free and works really well.If you have only one memory module installed, test it with Memtest86+\015\012utility or try to replace it with a known good test memory module and\015\012see if it fixes the problem. If you have 2 memory modules installed,\015\012try to remove them one by one and start the laptop after each removed\015\012module. It is very unlikely that both memory modules fail at the same\015\012time and if your laptop starts with one module, most likely the second\015\012memory module is bad.
\015\012It is also possible that the memory slot on the motherboard is\015\012defective itself. Try to move the memory module from slot A to slot B\015\012and try to start the laptop. If the laptop works when the memory\015\012installed in the slot B and fails when the memory installed in the slot\015\012A, them most likely the slot A is defective itself and the motherboard\015\012has to be replaced.

Hope i helped you.

Hi,

Does your mouse appear on the blue screen if you move it off from one of the corners of the external display? Are you able to drag programs in and out of the display?

It would appear like the desktop is extended if you can move the mouse from the screen to the other the screen is working perfectly.

PC goes to blue screen of death and shuts down what are the possible problems! I installed microsoft office 2007 and photoshop CS2 and Auslogics on the computer! And I never restarted! But I think that it shutsdown because there are too many processes running at the same time and the computer some how wants to protect the memory from going over board. I turn it on and in about 6 Seconds it goes to blue screen and shutsdown and atemps to restart. But it may just be that there are to many processe
