It would be helpful if we knew the Make, Model of Laptop and the OS you are using? Try a hard restart , remove ALL media, DVD, CD, USB, etc., unplug , remove battery, leave battery out, plug in , reboot. Describe what happens, Fan spins? LED's blink? HDD spins up? Sound? Anything on screen? Have you tried a System Restore/Recovery? You can start by removing the HDD and testing it, if you done have a USB to sata/ide adapter take it to a Qualified Computer Tech.

    You can start by removing the HDD and testing, Is you done have a adapter, take it to your local computer shop. Have you tried a System Restore/Recovery? Or trying to Boot to Safe Mode? Does the HDD Led blink on boot? This HP Manual may helphttp://www.hp.com/ctg/Manual/c01295820.p... Make sure your Laptop isn't overheating due to dust, dirt, clean the fan, vents, heatsink. SEE:http://www.tomshardware.com/forum/256123... t sounds like a HDD issue, but I can't be sure until you test it.

  • Saad Ahmed May 07, 2013

SOURCE: My dell vostro 1000 laptop's display aint working.

hi,
try these two things if both don't work you should call dell tech support

1) take out the battery and the ac adapter and then push and hold down the power button for 15 seconds, this releases flea power in the laptop and makes it work sometimes
if it didn't work

2) take out the battery and put in the AC adapter and try to start your laptop on AC adapter alone, if it starts that means either your battery or *********** board is bad, you can check if the battery is bad by replacing it with a new battery and if it works with new battery that means the old battery was bad but if it only works without battery with ac adapter and new battery also didn't work, that means motherboard is bad, Call dell tech support

If you think the info given by me was helpfull please do rate me

SOURCE: My CQ61-411WM doesn't boot anymore. Symptoms:

Hi

If the graphics card was intact, the external monitor test would have given you an image.

Unfortunately, this seems like a graphics card problem common to this manufacturer (google HP Compaq Notebook Graphics Problems).

This fault can be repaired only by specialist laptop repairers with specialist tools.

The repair is called Reballing the Ball Grid Array.

Reballing has a marginal success rate and even if successful, the fault can reoccur. A typical professional repair warranty would give you 3-6 months post-repair warranty.

Sometimes the surface of the graphics chip is too damaged to repair.

This repair can be expensive as it may involve several time and labour intensive rounds of disassembly, repair, reassembly and testing.

If you do opt for repair, ensure that the repairer is a specialist, properly equipped with an Infra Red Workstation, experienced in this specific type of repair, is willing to do a No-Fix-No-Fee Repair and offers a Repair Warranty.

If the laptop's warranty has expired and the repair cost seems high to you, it may be time to consider a new laptop.

Sorry for the bad news.

Hope this helps.

Toshiba Satellite M305D-S4830 laptop won't boot up. It sounds like it starts to (can hear fan), but the screen never comes on.


It sounds like either your display is turned off or the backlight went out. If you have a display selection button on your laptop(usually on one of the function keys), try that. If that doesn't work, try plugging it in to a monitor or other display and check if that works correctly. If it does, your screen either has a bad backlight or other physical problem.

Monitor is dark. how to fix?


Walt, hold the Fn key down again, and tap once more on the Acer, F5, Display Toggle-Over key.

There are at least 3 display options available;

1) Internal display of laptop ONLY

2) Internal display of laptop AND external display

3) External display ONLY.

Were you just using the external display for more 'display real estate room', or was/is there a problem with the internal display of the laptop?

Was no problem? Is now? Even when using the guidance stated above for the Fn and F5 key?

Then if your laptop uses a CCFL for a Backlight, it also uses a screen Inverter. Screen Inverter is bad.

If it doesn't use CCFL/s for a backlight, and uses LED backlighting, replace the LCD screen.
The LED backlighting is incorporated in the LCD screen assembly, and you ain't replacing it.
Replace the entire LCD screen.

Post the laptop manufacturer name, and model number in a Comment. Model number is on Bottom of laptop.

Hi..i am using compaq presario cq 40 and screen is flickering.i had it checked and they told me lcd is the problem but they didnt even bother to check.they just turned it on and they told me that i have to...


When it flickers, can you still see the text when the screen goes dark?
May have to use a bright flashlight set right on the display to see
the text on the screen beside where the light sits.
That will tell you if it's the backlight.

You can also look at a grazing angle into one of the edges to see if the
backlight is flickering when the display does.
When it's cold, does it start with a slight pinkish color? That can be
a sign of backlight going bad.
Anything interesting happen when you flex the cable by moving the screen?

I'm not saying it's impossible, but I've never seen software cause
consistent screen flicker. And if the vga port doesn't flicker, sw is
even less likely the problem.

If you bet the odds, you'd bet on a bad display cable.
Won't hurt to try replugging it.

If that doesn't help, then your monitor may be dying....

My gateway laptop didn't start up,when powered on only black screen appears


Hi jeangray 17,

If you see power lights but nothing appears on the screen, it could be a "POST" (Power-on Self Test) problem or simply LCD problem.

Here are some steps that you can try.

1. Remove the battery and the ac adapter then press the power button for at least 20 seconds to drain electric charges left from the system. (You may need to repeat this step to get it work.)

2. If above step doesn't work, try to plug in an external monitor and see if you get display from the external monitor. You may need to press the Fn + F10 or F6, depends on the key designed on the keyboard to toggle between displays.

3. If you get display from the external monitor, I'm sure your having problem with the LCD components. In this case, check and replace faulty LCD backlight, LCD cable or LCD inverter. The LCD inverter is often a culprit.

4. Try to reinsert the memory module/s (RAM) of the unit, try using one RAM at a time to see if it works. A faulty RAM will cause the issue not to POST.

5. If reinserting the RAM doesn't help, most likely your motherboard needs to be replaced.

Hope this helps.

Acer 5515 backlight not working also bootmanager missing


You need to fix the boot manager problem first by connecting an external monitor to the laptop so you can see and do a system repair.

As for the backlight problem :-
You could have a faulty CCFL lamp or inverter, To determine if you have a LCD screen, inverter or video card problem, read this and follow these 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 or appear black. 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 the monitor up first then the laptop, 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.

Black Screen


try hooking up an external video source. Check to see if the computer is actually booting up. if the computer boots up, then the LCD invertor or Backlight of the screen is bad, need to be replaced.

If the computer does not boot up after hooking up an external video source, then most likely your motherboard is bad!


need to be replaced.
