My gateway laptop just lost its lights on the display works well but no screen lights
On my laptop the light comes on and shuts down after about 6 seconds. It behaves exactly this way after whatever I do to engage it; turn the computer on, wake up from standby, press and release the "lid closed" detection pin, ...
There is a button on the keyboard with a light blue "Fn" on it. While holding it down I can adjust different settings such as illumination, contrast, etc.
I noticed at one occasion that pressing it right after engaging the light it shuts down prematurely (quicker than the 6 seconds I mentioned above).
So I tried to crank the illumination down and up to max (while the lights were "off"), press hold and release the "lid closed" pin and after a few attempts the lights came on and stayed on without shutting down again.
If the computer goes to standby or powersave or whatever that invokes it to shut down the display light I have to struggle this way again in order to revive it.
I also noticed that when adjusting the illumination, if I go below a certain threshold, the screen goes completely black. It seems like the lowest notches of the illumination control cannot supply enough voltage to run the display light although it doesn't show any signs of impairment once it starts working (e.g. abnormally weak light, yellowish color, flickering, ....).
Does anyone have any clue as to what is malfunctioning?

Re: 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.
Note: 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>.
Note: 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.

1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
If you can, try and connect your laptop to an external display and see if it outputs to that display. If so, you may have an LCD or video card issue. If not, it could again be the video card or the motherboard. Look for blinking lights when powering on the machine. These can oftentimes be errorcode displays.
Your Gateway laptop comes with a series of LED lights that alert you to the state of your computer. You'll notice there are blue, purple and red lights that either blink or display solidly. Each light, blinking or solid, has a different meaning. The blue blinking light on your laptop indicates that it is in Standby mode. Your laptop goes into Standby when you close its lid without shutting down the computer. To turn this light off, you'll need to take the computer out of Standby mode, and if you want to ensure that the blinking blue light does not return, shut down the computer after each use.
Open the lid of your Gateway laptop and press the power button. Once Windows loads, enter your password if required. The blue light will no longer be blinking because the computer is no longer in Standby mode. Shut the laptop off when you finish using it rather than simply closing the lid to stop the blue light from blinking again. Click "Start" from your Windows desktop and click "Shut down." Change your computer's power settings to keep if from going into Standby mode when you close the lid if you'd rather not shut down your computer every time you use it. Click "Start" and click "Control Panel." Click "System and Security" and then click "Power Options." Click "Choose what closing the lid does" from the list of options on the left side of the window. Select "Hibernate" from the drop-down lists under "On Battery" and "Plugged In." Click "Save Changes." Your laptop will now bypass Standby mode when you close the lid and it will enter Hibernate mode instead. Hope it helps.
How old is it? Perhaps the Monitor is gone or graphics card or it could be as simple as a tiny switch that shuts-down the monitor when the lid is closed. need more info. What red light? I have a old Gateway MX6421 Laptop
I also had this problem. I turned it off and it would not turn on. I found the solution. First, extend the laptop screen as far back as it will go. Don't just stop the screen at a ninety degree angle. My laptop screen pulls back to about 135 degrees. Now press the power button. It should start up.
Why do I think this works? Well...I used to own an older model thinkpad that had a short "male" connector on the screen, that when the screen was folded down would enter into a "female" connector on the base of the unit and trigger sleep mode on the unit. This is how the system could automatically hibernate when the screen was closed. The little male connector broke off, and I couldn't get the system to wake up, because the connection to tell the laptop that I had the screen up or down no longer worked. I couldn't even power it up. I had to take an ink pen and push the connector through the female end to indicate to the motherboard that I'd opened the screen before it would even turn on.
It appears that the same type of mechanism is built into the long BAR under the screen of the NV52 and somehow it can't determine when the screen is open or closed. If it detects that the screen has not been opened, it won't power up. This safeguard prevents the laptop from being turned on mistakenly while closed up in your laptop bag. Extending the screen back resets the mechanism and it should turn on. Sorry for the long explanation...
Sometimes it di happen , specialy in most laptop which is being used more frequently and longer usage, the advisable use of a laptop is atleast 2 to 4 hours then shut it off and have cool down for 30 minutes to one hour then you can used it again, unless you got a support inclined base for laptop with support ventilating fan to help down minimize the heat accumulated during the usage.
have it check your video card with the proper technician, but first try to cool down your unit and try to open it again, and if still does'nt work then have it check by the service center
Hi, do you mean to say that your system shuts down when you are not pressing the laptop ie, the power light also goes off when you are not applying the pressure, or just the monitor goes blank and power light is on when there is no pressure in both the above cases i think you should call technical support for your laptop, because it seems like a hard ware problem
See if you can attach an external monitor to your laptop.If you can and you can see your display on the monitor the it is a faulty laptop screen .If you see nothing on the x monitor then the graphic card/chip is fried.
There are two possibilities, neither is really for a novice.
TURN OFF LAPTOP, REMOVE AC PSU AND BATTERY
Open the laptop lid and check the thin ribbon cable (looks like dirty yellow or orange scotch tape with several small thin metal lines parallel to each other). This comes down from LCD/screen, to the lower laptop case. It will have a connector that has a clip/release compressing the ribbon in the jack. Release it, and GENTLY pull the end out. Old laptops get oxidation here that causes your symptoms. Use a stiff piece of CLEAN denim material ("jeans" to "buff" or "polish" the bare metal at the end of the cable. Then insert back into the jack and press the clip down evenly.
Reassemble laptop. If symptoms remain, then it is your fluorescent tube. Laptops have VERY thin fluorescent lights, about 2-3mm in diameter. You need to open the LCD/SCREEN case, and take NOTES how everything is taped inside as you disassemble. On the sides or top will be (usually) two, sometimes only one illumination tube sealed in a channel. If it has black or grey color at either or both ends, it is burned out. You will need to remove it and replace it. If the tube is NOT burned out, then it is either the connections (check all, in the area/connecting to tube). Last, if nothing was loose then your inverter is bad. If it is soldered to the main board, your laptop is "toast". It is over, unless you can find a GUARANTEED used or new replacement for a price you feel is good. However, if the inverter is inside the LCD/Screen/LID, this can often be a plug-in unit that is replaceable, if you can find the parts (again, for a price you feel is worth it).
