I have a Dell Inspiron 6400 laptop with WinXPSP2 2gb DDR2Ram, 14 months old. Computer worked fine in AM but after packing it and a trip of 350 miles by car, it gave me a black screen with no letters, logos or Dell signon nothing.

This problem was diagnosed by Dell via telephone as a memory problem and they advised replacing Ram. This was done and I was able to logon, access the internet but after a second logon, I got the same black screen.

A technician/friend said it sounded like a short. I loosened every screw I could see on the bottom of the computer and was able to logon once again and save all data. It now works sporadically, i.e., the screen will still go black but unexpectedly and often after an hour or two of use. An external monitor works fine, even when the laptop screen goes black.

Is there anything else I can do other than take it to a repair shop?

Thank you for any help you can provide

the screen is gone, if you can handle using it with a monitor I'd keep it, otherwise it's going to cost more to fix than it's current market value.

14 months, still under warranty? FWIW Dell's support site offers excellent tutorials how to dismantle it. Might just be the wires to the screen got pinched. Who knows

"Dell-branded hardware products purchased in the U.S. or Canada come with either a 90-day, 1-year, 2-year, 3-year or 4-year limited warranty, depending on the product purchased." most of the time it's 1 year, maybe 2. without the service tag, hard to say how long the warranty is.

Thank you for your responses, esp Garmanma. Couldn't agree more with your quote being a grand-dad myself :-) I have visited some of the sites on dismantling but couldn't find an up-to-date Dell tutorial. I've decided to take it to a shop and have them try to reseat screen cable. The monitor is fine, just the unpredictable black screen that I can sometimes get back by moving the screen a bit. Thanks again,
irnman

Thank you Mark: I visited the site and the problem is solved. All I did was reseat the display cable connector and it seems to be working fine now. Your help is sincerely appreciated as is bleepingcomputer.com
