I have hp pavilion dv6226us and when booted up the screen stays dark. You can see display only if you shine a light onto the screen. I tried to turn up the brightness and did't have any luck.

Hi AC9746

The 1st thing to do is connect an external monitor to your computer. Connecting an external monitor to it will very quickly point us in the direction we need to go in troubleshooting the issue.

You may need to close the "lid" of the computer in order for the display to show up on the external monitor. Hopefully this will work since you're unable to see the display properties in order to select the external monitor.

If the display works w/ an external (**known good**) monitor connected to it then the issue is w/ the laptop's monitor. The next course of action is most likely to contact HP for warranty repair (if your computer is in warranty) or to replace the monitor.

If the display still doesn't work w/ a **known working** external monitor connected to it, then the issue is w/ the onboard video.

You can find manuals for your laptop HERE. However, I don't see a service manual there.

You can find HPs "Solving Problems" for "Display, Video and Graphics" HERE.

    Hello AC9746

    How did it go? Did the information and links I provided you w/ enable you to determine if your LCD monitor needed warranty repair or replacement?

    I DO hope that is the case. :) If it isn't, please, post back here and we'll continue to work w/ you.

    If it is the case, would you kindly take just a moment to close the problem by assigning a FIXYA rating for my "solution"? I would be very grateful for your generosity and show of appreciation.

    Thank you once again for using FixYa! Have a beautiful day.

The VGA card or the VGA driver is not properly installed,perhaps.Try reinstalling the driver.
If you suspect the monitor brightness controls then try fiddling with them untill the brightness is good enough.
Check monitor cable also(VGA).

"HP Pavilion m7580" is not


Hello,

To verify whether it's a no POST issue, press NUM LOCK or CAPS LOCK key and check whether the CAPS LOCK or NUM LOCK lights are lit or changes when you press on it. If it doesn't then it's a No POST problem.

However, if the computer screen shows the HP logo or a display then it's POSTING and is experiencing a No BOOT issue.

If the NUM LOCK or CAPS LOCK responds when you press it but there is no display, check the connection between the monitor and the CHASSIS or CPU.

If you have verified that it's a No POST issue because CAPS lock is not responding, you need to open up the chassis to do a troubleshooting procedure. Be sure to unplug the chassis to all the connections especially the power cord. Drain the power by pressing and holding the power button from 8-10 seconds.

Here are the things that you need to do after you open up the chassis.
1. Reset the Memory sticks. Connect the CHassis to the power and monitor. If no go, try turning on the computer without the memory sticks. The aim of this troubleshooting is to see a display on the screen. Any display would be a good sign. If no go. Put the memory stick back in.

2. Remove the CD drive. Turn on the computer, check for development. If no go, proceed to step 3. Just leave the cd drive removed

3. Do the same thing with the other devices like the hard drive and other devices inside. Your aim is to see a display.

Let me know if what happens and I'll get back to you.

Once you see a display. Let me know by replying to this thread.

I have an hp pavilion computer it turns on fine but my monitor is not displaying anything


Before you turn the power onto the computer make sure you have the monitor on. When you power the computer up you should see a very quick flash as the computer boots up. If you don't your monitor is either bad or your video card. Make sure the monitor is plugged in tightly into the adapter that it fits into.

When pluged into outlet fans spins and doesnt stop, wont boot


Fan spinning hard is usually a CPU issue.
If you've made any hardware changes to your computer, undo them. This happened to me when I was trying to upgrade my Processor (CPU) and I had the wrong kind.

HP Pavilion M9040N Elite, power lights come on, will not boot


unhook everything that is hooked to it ! Except the keyboard mouse and Display. now try it ! If that doesn't work try to start in safe mode then do a system Restore to an earlier date. there could be a number of things to cause this even a mouse, So one at a time try to remove all that you can and then go from there and one at a time hook all back up until you find it. if not there have to start inside the machine, Doing the same thing/ video,sound,cd roms/floppy/etc.hope you find it in the first round.

Hp pavilion a465c desktop which will not boot


Make sure the power supply switch on the back is set to 115v, its normally a red switch but could be black.

Once you do that see if you can turn on the computer and get video.

If not then with the computer turned off, take out the memory sticks and reseat them one at a time in each slot one at a time and try turning on the computer to see if you get video. If you still don't get video then try taking out the CPU and reseating it back into its socket properly. At the same time make sure there is no dust or dirt on the cpu or in the socket.

Try again and see if you get video. If you don't get any video this time then disconnect everything and only have power going to the motherboard. If you do this and you still don't have video then the motheboard is bad and would need to be replaced.

Emachines 1900+ gets power to the monitor and computer but wont boot


There could be a number of causes. Do you hear any beeps when the computer starts up? Try seating all the chips in the motherboard. That means, apply pressure to each individual chip on the motherboard with your finger or thumb. The goal is to make sure each chip is securely attached to the board. Sometimes, heat or new h/w installs partially "pop" some of the chips out of the motherboard - causing the circuitry to be disconnected...
