my screen keeps going black - help!

Hi all - I have a dell inspiron 8100 notebook computer. Here is my tale of woe: Yesterday afternoon I turned on my computer and about 30 seconds into start-up the screen went black. I turned off the system and turned it on again. Again the screen went black. After about 3 more tries the computer started up properly and all was fine...until this afternoon. I used my computer earlier this morning and everything was fine. I turned it off and came back to it about 3 hours later. After I had been using it for about 10 minutes the screen went almost completely black. The computer was still on, but the monitor was dark. I turned off the computer and restarted it. The screen went black after about 3 minutes. The same thing happened about 4 more times before I decided to call dell for support. The dell representative I spoke with had me take out the battery, unplug the power source, and hold down the power button for 30 seconds. I then restarted my computer and the screen went dark after 3 minutes. He then had me reinsert the battery and restart the computer. Once again the screen went black after 3 minutes. The representative said it sounded like I had a loose connection; however he couldn't tell me how to fix it since his system was down. He said he'd call back again this time tomorrow - but I'd like to fix this asap. So I'm now writing you for help from my husband's computer. Help me please...what can I do to fix my computer? Thanks! - Margaret

Connect an external monitor - does it go black as well?

If it's a loose connection, the first thing I'd re-seat would be the flex cable, instructions here:

Re: my screen keeps going black - help!

Ok, after about an hour of fooling around with my system, watching it behave when I wanted it to mess up, and having it mess up when I wanted it to behave I think I've isolated the problem. I hooked up my notebook to an external monitor and after starting and restarting it several times without any problems the notebook monitor finally went black while the external was fine. So it's a problem with the notebook monitor (or the notebook monitor connection). Now...what does this mean? Does this mean I should try following the directions in that helpful reply to my query to reseat the flex cable? I'm really nervous about opening my notebook up and messing with anything. I don't exactly have a degree in computer science...Thanks!

Re: my screen keeps going black - help!

I don't wish to hijack your thread at all, but I wouldn't mind getting an answer, also.

I just bought a 9100. It arrived today. When I plugged it in it started up ok. I clicked on the User Agreements and it went on to set-up, then I heard a sound and the screen went black.

I tested the electrical cord, wriggled the cursor nub, hit keys... nothing. I shut it down and started it up again.

It got a little farther into set up when I heard the little noise again and the screen when black.

Hmmm!

I tried emailing tech support. Got an error notice (and what does being a on the customer server mean, anyway?). I tried looking under Help topics and got a "check back later" message. I sent off a complaint to the website feedback (that worked!). And now I'm here...

This is not a good sign!!!

Box looked undamaged by shipper, btw, so I doubt I can lay the blame there...

HELP.

Re: my screen keeps going black - help!

Chances are the backlight or inverter is failing.  If you are under warranty, call Dell;  they will replace the screen.

If you're not, a notebook repair shop can repair the screen at much lower cost - $150 or so vs. $700+ for a new screen.

Re: my screen keeps going black - help!

Hmmm... so it's something that needs a repair? No easy fix... That's too bad.

It should be under a regular mail-in warranty, since it's brand new out of the box (well, actually, it's a refurb--but still under the regular basic warranty). Poor components are gonna get all loose being shipped back and forth... but I guess there's no help for it.

Thanks for the advice!

the display finally came on and stayed on until I shut down about 15 min. later... I wonder if I should keep testing it out...? I'll probably post back here tomorrow... if I keep getting no display then I'll get ahold of Dell and see about shipping it back...

He was talking about the origional poster - thats what happens when you jump into the moddle of a thread with a different problem.  Call Dell Sales and schedule a return for credit - you have 15 days.  Then order another.

April L, if you just received it and it is playing up then just send it back to Dell and get a refund then re-order another, yo should not have to put up with faults.

For the original poster, as mentioned your backlight/inverter is probably dead. If you still can see a shadow image then its definately your backlight/inverter. If i'm not mistaken you can replace the inverter without changing the whole LCD which is cheaper. But as far as parts are concerned i thick its easier to find the whole LCD with inverter.

After 2 dell technical support calls, a couple of posts to this forum, and endless fooling around with my computer it looks like my problems will soon be solved. After speaking with a couple of dell technical support people this morning it looks like my LCD screen needs replacement. Fortunately I'm still under warranty and dell's going to send someone out tomorrow (cross your fingers) to replace the screen. Thanks for everyone's input!
