Question about Dell Inspiron 8500 Notebook

Display failure after having lid closed while running

When i let the 8500 run with the lid closed, after some time, the display stops working and there is only a thin, 1-2 pixel high line at the bottom of the display. after a few minutes of powered-off rest, this problem is gone.

the machine also suffers from intermittent hard disk reading problems at bootup, which occur irregularly. they seem to be unrelated to the hard disk itself, since it runs fine in an external USB case.

Re: display failure after having lid closed while running

The solution to your problem is probably not the monitor, follow these steps:
1. Connect and boot your computer with 2 different monitors.
2. If it does'nt work with either of them the problem is from another computer component.
Posible Problems:
1. Your video card may be damaged or moved from it's slot.
2. Your proccessor may be damaged.
Posible solutions:
1. If you have computer hardware knowledge open the case
2. Remove the Video card.
3. Insert it back or insert another video card from a friend.(if it works with your friends card, obviously the video card is the problem)
4. Restart your computer and see if it works.
Now if it does'nt work after that you will have to replace your proccessor with one that works, from a friend, because you say your computer boots but if your monitor doesn't work you don't know for sure if it boots corectly.
The steps above are only for people with hardware knowledge, if that is not your case you should contact a computer service.

It is possible that is a virus, especially as you did nothing that could have damaged the hardware. However - one other thing that may be causing this is a failed power supply. It may be that the computer is no longer getting enough power to run the graphics card properly. You could try removing any PCI cards and extra fans (appart from the CPU fan obviously) to see if that allows the PSU to provide more power to the graphics card. But there's no old is the PSU and is it branded?

Also, did you download anything whilst on the internet before hand? Or click yes to any of those warning prompts?

Id say the chances of it being a BIOS destryoing virus arnt too high, unless you already have suspicions about this.
Have you moved the machine at all ?

or else

Another thing that can cause ýour problem is if the CPU is dead or if clock frequencies/memory timings are wrongly set. You might want to try reseting the CMOS by removing the mobo battery...although its hard to see how this could be the case if you haven't messed around with it.
Does the computer give you the single POST beep? Is there no BEEP? (Do you have the system speaker attached, check this first ) Or is the beep different to usual? If you do have a working speaker, you should be able to rule out a few things. I mean, if there is no continual series of beeps, it's not your memory, if you don't hear a long beep, its not your graphics card. Reset your CMOS (check your motherboard manual, usually involves moving a jumper then moving it back).

Let us know how things turn out and don?t forget to rate the posting.

Hi i have just got a new Pavilion DV7 only a few weeks old on boot/start up it starts then goes off several times before it starts to load windows the fan starts and the lights come on then goes off...

Run CHKDSK/F to check for errors. There may be an error on the hard drive.
Closing the lid when closing down, puts it in sleep mode and it will restart much easier but the error should be removed.

My Laptop will not Stand-By

There are 3 parts to standby. Your version of windows must support it. You have the utility enabled and working. The display switch must be operating.

If you have checked the power utility setting and are sure they are right and the utility is installed operating right then your problem is the lid switch.

On some models you can see it under or along the bottom edge of the screen. To check if it is working use something like a tooth pick to depress the switch. The display should at least blink out when fully closed. If you can't find it or get at it you can close the display and try to spot any light coming from the screen. It should be easy to see but if nothing else try a dark room. The display should go dark as the lid closes fully. It will be pretty close to when its down so can be hard to see when.

If the display is working after you close then the switch needs replacement. If it goes dark then I would reinstall the power utility as something may have got corrupted.

No display lights

Run the PSA Diagnostics and Obtain the PSA Error Code

To run the PSA diagnostics and obtain the PSA error code, perform the following steps:
Shutdown the computer.

Press and hold the <Fn> key, then press and release the power button.
Release the <Fn> key when the lock lights above the keyboard begin to flash or Diagnostic boot selected is displayed in the upper right corner of the screen.

Release the <Fn> key.
The PSA diagnostics sequence begins.
After approximately 2 minutes the system produces a number of alert tones.
After the alert tones, the system produces either a series of low beeps or error codes.

PSA diagnostics will prompt for input during some tests. The resulting error message does not necessarily indicate hardware failure.
For example, input is required during the color bar test. Failure to input a response will eventually result in a timeout error: 1000-0333 Graphics test timed out waiting for keyboard response. This does not indicate a graphics failure has occurred.

Note the sequence of beeps or error codes.

Initialize LCD BIST Diagnostics

You can initialize the LCD Built-in Self Test (BIST) in two ways, depending on the revision of Pre-boot System Assessment (PSA) diagnostics:
PSA versions 3019 and greater run LCD BIST immediately after failing the color bar test, via user input of <N> or waiting for it to time out prior to generating the 3-3-3 or 3-3-4 error. PSA version 3019 became available in November 2005 on various Dell laptops. The PSA version is upgraded with the BIOS.

With older versions of PSA diagnostics prior to November 2005, LCD BIST runs after responding with a <Y> after receiving a 3-3-3 or 3-3-4 error code.
To initiate the LCD BIST on PSA versions 3019 and greater:
Boot to the PSA Diagnostics.
Watch the screen and listen for the color bar test prompt tones emitted by the PSA Diagnostics. If the screen is visible, one will see the PSA diagnostics draw a series of multi-colored bars across the screen. When completed, a prompt asking if the pattern was seen appears, accompanied by a brief series of tones.
Press <N> or wait approximately 30 seconds to fail the color bar test.
Watch for the LCD BIST color generation and listen for the beeps every 2 seconds that indicate LCD BIST is running.
LCD BIST runs for approximately 20 seconds, then stops. The 3-3-3 or 3-3-4 error code is then displayed when the LCD BIST is complete. If LCD BIST does not initialize, then the system may not have been upgraded to PSA version 3019.
To initiate LCD BIST on systems with PSA versions prior to 3019:
Boot to the PSA Diagnostics.
Watch the screen and listen for the color bar test prompt tones emitted by the PSA Diagnostics.
Press <N> or wait approximately 30 seconds to fail the color bar test.
The system emits a 3-3-3 or 3-3-4 PSA error after failing the color bar test. Wait for two iterations of the failure code and then press <Y>.
On a working LCD, the PSA diagnostics shows the following message:
Error Detected, continue testing? Yes or No or Retry.

Watch for the BIST color generation and listen for the single beeps that indicate LCD BIST is running.
Patterns of flashing color should appear on the screen. With every color change, an audible beep is heard. If the patterns of color do not appear, and the beeps are audible, an LCD failure may be the issue. If the patterns of color appear, a video card or motherboard failure may be the issue.

Thanks and Goood luck! =)

Logging Off and won't come back on what to do

You can shut it down hard (by holding the power button until it shuts off), wait at least 10 seconds (for your hard drive to stop spinning) then start it up and then try shutting down windows normally instead of just closing the laptop's lid. You can then go into user accounts and delete all accept for your Administrative account (even Guest account), and see if that cures your ills.
Good Luck.

A program that is stopping your computer from being "idle" will stop the computer from going into standby. An antivirus program doing a check in the background, or a backup utility or another background program could do this. Try to terminate the various running applications and see if the problem goes away, then you'll know which program was the offending one.

As for the lid, just doublecheck - go to control panel->power options->advanced and the dropdown that says "When I close the lid of my portable computer" should read "Stand By"
