Question about HP Pavilion dv6000z Notebook

Monitor went to sleep and won't wake up

After the screen saver times out, the monitor goes to sleep. This is indicated by the blue power indicator flashing. The monitor has gone to sleep, but will not return to normal operation. There is no picture displayed. I have tried another monitor, that works fine. I have tried rebooting, but nothing seems to help, including a power off/on of the monitor. What's happening? Thanks! Same problem. Put the laptop to sleep manually, or automatically, and the monitor does not wake up. I have an HP Pavilion entertainment PC.  I read a few other blogs, and it seems like the problem may be related to the graphics card.  I think this laptop is using the ATI Radeon graphics card.

It sounds like a driver issue, but more likely the monitor driver, not the video card, since the other monitor works properly.
If you go into the video properties, check the monitor settings. You should be able to switch it to a generic monitor. You also need to make sure that you have the correct monitor refresh frequency set. If you have a mis-match, the video card could send signals at a rate the monitor can;t handle, which is why it won't "wake" even after a reboot and might need to be unplugeed to get it to come back on.

My HP Pavilion dv3 won't wake up.


The HP DV series or laptop are known to suffer from GPU faults and issues. The syptoms you describe indicate such a fault. To help isolate the fault you will need to try plugging the laptop into an external screen when it is powered off, Power the laptop up and if the GPU is healthy it should display fine on the external screen leaving us free to look at other issues. If it does not it likely your GPU is at fault. If this is the case you would either need to undertake re-ball/reflow repair on the GPU, which is best done by you local repair shop unless you have the tools/skills to perform such tasks. Alternatively replacing the mainboard in the laptop could be an option.

Let me know if you try an external monitor. If it does display I will try to guide you through testing for other faults and issues.

HP Pavillion screen goes black when inactive for short time. Even when I fixed all of the power settings to never shut off or go into sleep mode. If I don't use it for 30 seconds then the screen...


A blacked-out screen doesn't necessarily indicate a broken monitor.
If the computer has run out of charge or is in hibernation or sleep mode,
if the screen is too dark, or if the display cable has come disconnected from the motherboard, the screen may appear black or fail to turn on. To fix a blacked-out laptop screen, troubleshoot the screen settings, check the LCD connector and see if the computer is awake and receiving power.
Touch the touchpad or move the external mouse to see if the computer is asleep or hibernating. If the computer fails to respond, press "Enter" on the keyboard. Press the power button if the screen remains black.

Confirm that the power indicator light, found at the front of the computer or above the keyboard, is glowing solid green or blue. Confirm that the power adapter is plugged into the computer and into a wall outlet. Confirm that battery indicator light is glowing solid green or blue. Hold down the "Fn" key. Press the up-arrow to see if the screen brightness increases.
Some computers also use the "F6" or "F7" keys to increase screen brightness.
Hold down the power button for 10 seconds to turn off the laptop.
Remove the AC adapter from the computer, close the screen, and then turn the PC over.
Slide the battery latch to eject the battery. Pull the battery out of its compartment. Turn the computer back over, open the lid, and insert the edge of a flathead screwdriver or other flat, solid object beneath the bezel above the keyboard. Wedge the edge of the keyboard bezel off of the top cover.
Work your way along the edge of the keyboard bezel to loosen it.
Pull the bezel off the laptop.
Trace the cable coming from the laptop screen to the connector found beneath the bezel. Reconnect the display cable to the motherboard if the cable has come loose from the connector. Line up the tabs on the bezel with the slots along the top of the keyboard. Insert the right edge of the bezel into the gap above the keyboard, and then push the bezel back in place. Turn the computer back on. If the laptop screen is still blacked out, connect an external monitor to the video port on the side of the PC to confirm that the video card isn't defective. If the external monitor works, the LCD screen could be broken. If the monitor doesn't work, the motherboard or video card might need to be replaced. Hope this helps

My samsung RV511 laptop won't boot and the monitor keep on flashing on and off but the power indicator still ligths on


The monitor keeps flashing on and off? Or does your system keeps trying to reboot which causes the monitor to go on and off. Does the screen turn Blue before it goes off?

Power is on but no signal output to the screen


The following applies to Acer Laptops. You did not specify the brand of laptop you had. If your laptop is not Acer, the specific keys mentioned may be different and you should adjust accordingly.

If the power indicator is lit but nothing appears on the screen - The computer's power management system automatically blanks the screen to save power. Press any key to turn the display on.
If pressing any key does not turn the display back on, check the following....
1. The brightness level might be too low. Press Fn and the right cursor key to increase brightness level
2. Display device might be set to an external monitor. Press Fn and F5 to toggle to the internal display
3. Backlight might be turned off. Press Fn and F6 to turn on the backlight.
4. If the Sleep indicator is lit, the computer is in Sleep mode. Press & release power button to resume.

What is the problem if the screen does not go on green and orange light goes on


Is it in sleep mode or hiberating mode? Green or orange lights on the top of the laptop for not fully charge battery or some signal lights for your brand of laptop? If the later, you can check the manual to see what those lights indicates. Otherwise, you may put on the power cord and press the power button to wake it up or restart it. Then set the preference for sleep mode or hiberating mode in control panel, power options. There also could be a hardware issue though. You may need to press on the position of the processor so it will sit firmly on the mainboard and if possible check the connection of cards and hard disks and memories and make sure they are well connected. If there is still an issue, you can try to flash the BIOS, reset the hard disk to factory default according to the manual or there might be an issue with the monitor. Try another monitor connected to the other VGA port of the laptop.

Why my computer have this test? the monitor oud the test is "Monitor going to sleep"? why that? can you help me? please


It's not a problem. You get that message because windows has a default power setting that puts your screen to sleep to save energy.

You just need to check the power saver settings in Windows. You should be able to find those if you right-click your desktop and select properties. Those settings are associated with the screen saver tab, monitor power. You'll want to change those so that the computer never turns off your monitor, if you don't want it to show "monitor going to sleep", any more.

Computer monitor screen goes black after 10 - 15


This could be due to the power management settings in your notebook. I suspect that the notebook is entering either in to sleep or the screen saver is set. Check if the issue persists, if these are disabled.....

Blank screen after monitor sleep just blue flashing light


Hi,

First of all you can change the Power Settings in Control Panel. You can configure as you need. I mean after how much wait it should go for sleep n all.

If it takes 5 min. to wakeup that means you have so many applications running that system cannot manage or RAM is small.

The final solution just remove the Display drivers and reinstall it.

After removing please restart the system once to proceed further

Toshiba satellite a135 monitor goes black


You could have a defective screen - a defective inverter or a CCFL lamp.
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

Defective CCFL backlight, it may have the following symptom:

  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
