    Michale,



    If you have upgraded your operating system, you may also update the newest Catalyst Control Panel software.

    That may solve your problem.

When i turn the notebook on i can see nothing blank black screen


Sounds like one of two issues,

1. You have the internal display turned off. When you turn the laptop on you should hear a single beep. Do you see the Sony Logo during bootup? Have you tried to turn the display back on? Try pressing the Fn+F7, or Fn+F8, key combination. There are only three modes and these key combinations allow you to cycle through these modes. Either the Primary Screen is on, or the External Screen is on, or both are on.

2. You may have a bad video card or the screen is dead. When you power up the laptop, can you see a glow, but the screen is black? Can you see the Bootup Screen with the Sony Logo, but barely? Have you tried to connect an external monitor to the laptop to see if the video card is working? If you get video to the external monitor, the video card is working. If you don't, then the video card may be bad. If you are getting video on the external monitor, try using the key combinations listed above and try to cycle through your Internal/External display modes.If nothing shows up on the laptop display then the LCD screen may be bad. It could be the back light. Those are internal to the LCD. That means you will have to replace the entire LCD display on the laptop.

Hope that helps.

Hp g60t went into hibernation last friday it wouldn't come out of hibernation so i had to hold in the power button and shut down. laptop turns on but no video now the screen stays black. i tried a reset...


This issue could be due to presence of static charges or internal hardware malfunction of the notebook. To isolate the exact cause of the issue, perform the steps provided below.

Step 1: Hard Reset

To perform a hard reset, please follow the steps listed below:

1. Unplug the AC adapter from the notebook PC and remove from any port replicator or docking station.
2. Remove the battery from the notebook battery compartment.
3. Press and hold down the power button for about 20 seconds.
4. Insert the battery and plug the AC adapter back into the notebook PC.
5. Press the power button to turn the notebook PC back on.


This will discharge the static charges from the notebook. Now turn on the notebook and check for the issue. If the issue persists, then remove and reseat the memory modules of the notebook and check for the issue.

Step 2: Remove and Reseat the Memory Modules

You can refer the service manual provided below for information to remove and reseat the memory modules of the notebook.

http://h10032.www1.hp.com/ctg/Manual/c01602064.pdf

Refer page no: 52 & 53
NOTE: PDF manuals require the Adobe Acrobat Reader for viewing and printing.
Further, if the issue persists after performing the above steps, then the issue could be due to hardware malfunction of the video card or defective LCD display screen of the notebook. Hence, I recommend you to connect an external monitor to the notebook and then check whether the display works fine on external monitor or not.

Step 3: External Monitor

You can follow the steps listed below to connect an external monitor to the notebook.

1. Turn off the notebook.
2. Connect the monitor cable from the external monitor to the monitor port on the rear of the computer.
3. Connect the monitor to a power source and turn it on.
4. Press the Power button to turn on the computer.

At this time, please follow the instructions mentioned below for switching the display to the external monitor:

The notebook's video card supports three modes. Built-in screen only; external video only; and both on simultaneously (mirrored). If you're not seeing the image on the desired device(s), the notebook's video card is probably in another mode. Press FN + F4 to cycle through the display options: Notebook display, External monitor, both.

If you press FN + F4 once, the external monitor will display & there will be no Notebook LCD display.
If you press FN + F4 twice, the external monitor will display & there will be some shading on the Notebook LCD.
If you press FN + F4 thrice, both Notebook LCD & external monitor will display.

If the issue persists on the external monitor, then this could be due to defective video card on the notebook. However, if the display on the external monitor is fine, then the issue is with the LCD display panel of the notebook. In either cases, the notebook requires a detailed onsite diagnosis by a service technician.

I believe the information provided would be helpful to isolate the issue with your notebook.

Why won;t my laptop power up


This issue could be due to presence of static charges or internal hardware malfunction of the notebook. To isolate the exact cause of the issue, perform the following steps.

1. Unplug the AC adapter from the notebook PC and remove from any port replicator or docking station.
2. Remove the battery from the notebook battery compartment.
3. Press and hold down the power button for about 20 seconds.
4. Insert the battery and plug the AC adapter back into the notebook PC.
5. Press the power button to turn the notebook PC back on.

This will discharge the static charges from the notebook. Now check if the notebook works fine or not. However, if the notebook turns on and if the display stays blank then connect an external monitor to the notebook and check for the display on it.

Step 2: External Monitor

You can follow the steps below to connect an external monitor to the notebook.

1. Turn off the notebook.
2. Connect the monitor cable from the external monitor to the monitor port on the rear/side of the computer.
3. Connect the monitor to a power source and turn it on.
4. Press the Power button to turn on the computer.

At this time, please follow the instructions mentioned below for switching the display to the external monitor:

The notebook's video card supports three modes. Built-in screen only; external video only; and both on simultaneously (mirrored). If you're not seeing the image on the desired device(s), the notebook's video card is probably in another mode.

If you press FN + F4 thrice, both Notebook LCD & external monitor will display.

If the issue persists on the external monitor, then this could be due to defective video card on the notebook. However, if the display on the external monitor is fine, then the issue is with the LCD display panel of the notebook.
Incase, if the notebook does not turn on at all then the issue is due to internal hardware malfunction. In all the cases, the notebook requires a detailed onsite diagnosis by a service technician.

If your notebook is under HP warranty, then I suggest you to contact HP support to get the notebook repaired under warranty.

It displays colorful lines on the monitor...cant see nothing


Test your laptop with an external monitor and find out if the external video goes bad too. If both, internal and external images go bad, you have a problem with the video card.
If external works fine and only internal goes bad, most likely it’s either bad video cable or LCD screen failure.

FS050UA , COMPAQ PRESARIO NOTEBOOK PC CQ50-210US the screen has lines and a black spot


Hi,
Turn on the notebook and press F10 to get into BIOS screen. Even if the lines and the black spot appears then the issue is with the internal hardware of the notebook.
To check further connect an external monitor to the notebook and press Fn and F4 keys on the keyboard to get the display on external monitor. If the external monitor display is fine then the issue is with the LCD screen or else the issue is with the Video card of the notebook.

Hp pavilion ze5500 display monitor still doesn't work


IT could be a motherboard problem with the function key that controls the switching of the video infomation between the LCD screen and the external video connector.
It could be the function key circuitry on the motherboard that controls the back lighting levels on the LCD.

My hp 500 screen blank


The first thing to do is connect an external monitor to the external video connector since you can't troubleshoot what you can't see. If you aren't sure of whether your computer has started you can press the CAPS Lock key off and on to see if the indicator lights up. If the external monitor displays for you then use your Fn keys to switch between external and internal monitor. Control Panel's Device Manager will tell you if there is a monitor or video card fault. If the external monitor doesn't work then internal video adaptor is disconnected or dead. Another option is to connect your S3 video to a TV or DVD player. Some typical faults are a burned out CCD bulb in the LCD module, a ribbon connector bad or disconnected from the mobo to the LCD and a motherboard fried from spilling your drink onto the keyboard. Opening the the laptop is bad juju if you aren't qualified to put it back together but you can get service procedures if the computer is out of warranty and care to try.
