I have a Compaq LTE 5300 with an intermittent problem in the LCD display. Upon booting up occassionally the display will only show a blank "white" screen. The laptop boots up as the system can be manually shutdown. With remote monitor plugged in - never a problem.

This has occurred a number of times - sometimes after one boot it will be back to normal the next time - other times two or three times blank - then normal again.

I removed the keyboard and double checked all connections to the motherboard.

Best quess - poor connnection in LCD - cable problems - LCD problem??

When in docking station - never a malfunction.

Thanks for ideas and help.

I think you are onto something with your best guess. You said it yourself that there are never any problems when the computer is docked. All a docking station does any way is act as a port replicator. You can check the LCD connections yourself or you can have the LCD replaced if the computer is still under warrenty. My money is on that if you replace the LCD your problems will go away. You can put a monitor on the back serial port and you wont have any problems. If you do that it will indicate the there is a problem with the LCD or connection to the LCD. Hope that helps you.

move the screen forward and back a few times this will clean the connections (they run thru the hinges on the lid to the base) sometimes dust will get in the hinges and the video cannot may connection

good luck!
