Question about Computers & Internet

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 goes black. If I press a button it comes right back on but very annoying it won't stay on for longer when it is inactive!

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

SOURCE: not turning back on after sleep mode

I had the same problem when I first bought my Acer Aspire One a few weeks ago. I searched the web for answers, but it didn't really seem like anyone had a solution. However, one guy on a forum or website said something that gave me an idea - he said something like: What's the problem? Just open it up, hit the power button, type your password, and it wakes up.

Well, that didn't seem helpful to me at the time that I read it, but after thinking about it, I had a hunch. I had not set up my netbook to have a password (yet). So I did. And it's been waking up from sleep mode like it should ever since!!!

Hopefully, if you're reading this, setting a password will work for you, too. If you don't know how to set a password, here goes... Start...Control Panel...User Accounts...Change an Account...[Pick your name.account]...then the option to create a password should come up. Let us know if this works for you!

SOURCE: HP Pavillion dv9700 won't power up

Try removing the battery and using only power cord to turn the laptop on. If that fails, try turning it on without power cord, just on battery.

If none of those work, then most probable cause of your problem is motherboard. Hopefuly you are either under manufacturer warranty or you have extended warranty with your vendor where you've purchased the laptop.

If your laptop turns on on power cord, but without battery, then battery is the problem. Also, if laptop turns on when it's only on battery but it doesn't when you plug ac cord in it, then the adapter is the problem.

* check com cable all thru the video card socket,also check you video graphic card pci if its inserted properly,try to clean it first.

* might your pc is in Hibernate or Sleep mode

A power management mode that conserves power by powering down the system. In hibernate mode the current state of the system is saved to the hard drive, and the system will power down. When a user turns the system power back on, the saved information is read from the hard disk, restoring the last used settings. Hibernate mode is similar to sleep mode, however in sleep mode the power cannot be shut off.

go to control panel > power management and change or default the settings you wish.

Screen goes black. Put it in sleep mode. Then hit the start and it comes back on even with powercord in..what can fix it?


this could be probably due to static charges or corrupt bios settings.
Turn off the PC, disconnect the AC Adapter and remove the battery. Now press and hold the power button for 45 seconds.
Now download and install the latest BIOS update available for your notebook from manufacturer's website. If issue persists, reinstall the display drivers.
I hope this will help to resolve the issue.

Computer goes to sleep before it even starts up


Hi there, it appears as though the Power Options are set too short a time and the PC is going into sleep mode. Go to Start menu/Control Panel and look for Power options. Set them all to "never" This will prevent her PC from going into sleep mode. Good Luck.

HP Pavillion dv6000 Vista notebook crashes when entering sleep mode


This is a common problem with HP Pavilion laptops, including mine. Check and make sure there are no non-OS programs running that are trying to control power settings (like a power monitor program running in the system/task tray) and then turning of hibernation in the POWER SETTINGS and then for all "WHEN I CLOSE LID" and "WHEN I PUSH THE SLEEP BUTTON" and "WHEN I PUSH THE POWER BUTTON" select DO NOTHING, then APPLY. Then SAVE SCHEME AS and choose any new name. This will disable all sleep modes forever, but at least you can get on with normal use.

If you are geeky, try going into the BIOS and DISABLING anything marked WAKE ON, and disabling anything having to do with automatic power features, and then try hibernating and so forth normally through the OS again. Sometimes this works if there are conflicting settings in the BIOS also trying to increase power efficiency.

Good luck...
