Computer won't start - sounds 2 beeps


More than likely you have a memory or video card issue. I think your laptop has the Nvdia Graphics (Video) Card that was a manufacturing defect. If you get 1 long beep followed by 2 short beeps then it's the Nvidia Graphics Card that needs to be reflowed. Another sign also is that nothing posts on the lcd screen. Check the memory as described at the bottom and if it's not the memory it's your video card.

When you plug in the power cord is there any lights whatsoever on the laptop, where the plug goes in or on the AC Adapter of the power cord?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button. And if that's true maybe you was operating off the battery the last time you had it on and since the power cord is bad, it was not charging the battery so the battery is drained and the power cord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove the Battery, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in (leave the battery out) and hit the power button to see if it boots. If it does, you can put the battery back in and let it charge.


Maybe your DC Power Jack which is where the power cord plugs into the computer is bad. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.


Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Remove the battery, Remove the cover that houses the memory on the bottom of the laptop then remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

My HP Pavilion dv9740us Notebook PC dosent start the screen is black


Doesn't start as in nothing happens when you hit the power button? Or are you saying the Desktop is black, but it seems like windows started and went through the boot process?

If nothing happens when you hit the power button:
Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.

No display after reboot windows


If it seems like your system is running whereas you hear fans running, hear the hard drive running, see lights, heard the hard drive click during bootup, but there is nothing on the lcd screen then try the following:
1) Try hooking a external monitor to your laptop. It can be any type of monitor even one of the old style fat crt monitors as long as it has a vga cable to connect to the laptop. There is a sequence of keys you might have to hit to get the display to show on the external. Most times you hit the FN (Function key) and hold it while you hit the corresponding F1 thru F12 key that is for display. Usually the correct key will say CRT/LCD or it might have a display icon on it. If the image displays on the external monitor that means the video card is good.
2). Remove the external monitor and reboot the computer again. Now when it is done booting take a flashlight an shine it on the lcd screen. You are looking to see if you can faintly see the icons on the screen. If they are there but barely visible then the LCD Inverter is bad. The LCD Inverter is located at the bottom of the lcd screen just above the keyboard and the Strip around the lcd screen covers it. You'll have to take the lcd apart to get to it.
3) If you don't see anything when you shine a flashlight on the desktop, then the lcd screen has to be replaced. However, sometimes the cable on the back of the lcd screen has come aloose or just needs reseating, so unplug the cable and put it back then see if it shows an image.


Read Below if it is not booting at all when you press the power button.
Laptops don't boot for the following reasons: 1) Bad Power Cord. 2) Bad DC Power Jack where the power cord plugs into the laptop. 3) Static Charge Buildup. 4) Bad Motherboard.

The above 4 reasons are when you press the power button and absolutely nothing happens. You hear no fans running, no disk drive running, no one time clicking sound on the CD Drive and No light for a second or two when the CD drives click. In the case of a motherboard issue sometimes you will hear beep sounds or see blinking lights. Those beep sounds and blinking lights tells the technician what is going on with your motherboard and why it will not boot. If you see the blinking lights or hear beeps count them.

So you have a power light which means your power cord and dc power jack is good. So lets see if you have a static charge buildup.

Remove the Power Cord and the Battery from the laptop, then Press and Hold the Power Button for 30 seconds. After 30 seconds put the power cord back into the laptop, but leave the battery out. Press the power button to see if it boots. If it does you had a Static Charge Buildup and it's ok to put your battery back in. If it does not you more than likely have an issue with your motherboard.

You particular mode probably has the Nvidia GPU Graphics Card in it and it's a well document known manufacturer's defect all over the internet. If you see lights blinking or hear beeps but nothing appears on the LCD Screen make sure you count the blinks and count the beeps. More than likely you have the Nvidia problem and you missed the recall and the extended warranty because HP got away without tell all their customers. The only way you would have known is if you just happened upon their website.

You'll need to get your Graphics Card Reflowed and that requires a complete disassembly of your laptop. Get a quote from your local repair shop then check out the guys at: http://www.generalsystemsconsulting.com
They will repair it and ship it back by Fedex or UPS and their price will beat most quotes including the shipping.

Fujitsu Lifebook does not boot up


Have you tried draining the static on your computer?

Turn off the computer
remove the battery and adapter
press and hold the power button for 1 minute
plugged back in the adapter and battery
turned on the computer

if not resolved:

tried using an external monitor and connect to your computer to check if you can have a video on the external, if yes it is possible an LCD issue

Also, you may try using a flashlight in your LCD and check if you can see any, if none?

I suspect possible LCD issue.

Fujitsu LIFEBOOK C1020 power problem


or a bfoken powr jack.I replaced mine recently for £4.00 and took approx 2 hours.

Power supply


Does the AC adapter plug wobble where it plugs into the charging jack? If so, the jack's connections have broken free from the motherboard, so you can't charge the battery or power the notebook without it. Fujitsu won't let us "common folk" have access to service manuals. I had a Fujitsu, same problem, and I couldn't make it work any less, so I winged it, and succeeded.

Expensive to have a repair shop fix. If you want to try, email me at jacobson@sonic.net. I'll tell you how I did it (Lifebook C2240). It might be similar for yours.
