Screen seems dead, but comes alive once in a while

The laptop screen seems dead. It comes alive for a few seconds (maybe 2), when you first power it up, or when you play with the lid button, but immediately goes to being too dark. You can get a flashlight near it, and sort of read whats on the screen, login, navigate with mouse, and work, but its just way to dark.

Is the screen really dead ? What can i do to fix this ?

Yep its either a dead inverter or you need a new ccfl(the bulb)the bulbs are cheap but installing them is tricky-and new inverters are expensive and usually not common(best to get then by dead mans shoes)

Re: Screen seems dead, but comes alive once in a while

If the screen comes back on momentarly after pressing the lid switch, usually indicates a problem with the lcd inverter. Not knowing the Acer models at all, the inverter could be located under the removable LCD mask on cover or in front of the keybd. Quite often by reseating the inverter plug in connections several times, it will clean off a film that might be causing a poor connection. If this is a temporary fix you may need to have the lcd inverter replaced.

 Sounds like it is a problem with the backlight. Or the switch controlling the backlight.

I have a dell inspiron 1464 laptop i3 processor n windows 7. when i turn it on it makes beep beep sound with nothing on screen totally black screen. what is the problem

there are a few possible issues with the unit. it is definitely a hardware failure. 2 tips the beep indicate 2 different issues:

1. long beeps may indicate an issue with the motherboard.
2. short beeps that is continous as if saying sos is for the memory card

either way you would need to have your laptop serviced since it is already a black screen.

Lenovo SL500 Thinkpad

1. Take off the the power plug
2. take off the battery
3. press and hold the power button for 10-15 seconds

Now try turning it on, if it still doesn't work, check in your manual how to RAM cover, and take the RAMs out (before you do this repeat stpes 1-3). After the ram is out, try turning it on if you hear sirens , that could be at least some indication that your motherboard is alive. if no sirens --- than you got bad news.

So at least you will now if there is a chance if the motherboard is not dead.

Hi, I have recieved a used laptop from a friend.It is an Acer Aspire 1690LCi ZL3. The unit powers on,battery is good,DVD drive opens but the screen is dead.Please help. Sam

A few things to try. First turn on the unit, and after it seems to have booted up (like at a windows login or something), take a flashlight and in a darkened room shine it on the screen. If you can see a picture, it means your backlight is out. Go on ebay or elsewhere online and look for an acer aspire 1690LCi backlight. Then open up your screen and replace it (there should be tutorials online for this). If you don't see an image, your screen maybe be out or have more serious problems (video card, LCD dead, etc.).

Compaq Presario 1700 Laptop screen flickers and locks up

it sounds possibly that it is going into hibernation. a single press of the power button should bring it back alive.
also feel the bottom of the laptop.... if it is getting close to meltdown you need to clean the dust and dirt from the heatsinks. the fan area may appear to be clear but all the junk gets blown against copper heat sinks so you need to remove the covers to get at it.

Screen troubles

I assume you are running it under normal power supply (mains)?
Try checking your display settings, they may be set st a lower brightness level. As you switch on the computer it is taking a few seconds to catch up and dim down once the settings kick in.

Screen went black

When you close the lid, there is a small pin that engages the case and flips a switch to tell the laptop the case has been closed. The monitor will ALWAYS turn off then, because otherwise, the heat build up would burn the screen! Do not try to defeat this, replacing an LCD screen is usually more expensive than the value of the laptop!

Now, that all being said (and please remember), the situation you have now is (hopefully) just that the laptop tried/succeeded in going into ACPI "suspend" or "hibernate" mode.

1. Remove all cables and 10/100. Remove all USB devices. Just leave the PSU (AC power supply) connected.

2. Press the power button firmly, JUST once. Wait. And I mean WAIT, because some laptops can take 2 minutes or more to come out of suspend/hibernate, if they were very busy at the time it was shut down.

3. If the LCD screen lights up. you are done. But if it does not light up now, then proceed to step 4.

4. Press and HOLD the power button down for 10 seconds. This forces the laptop to shut down completely, even from suspend/hibernation. Some unsaved files may be lost, but tghe laptop goes cold, so you can start ACPI over again.

5. After a few minutes, press the power button again, firmly, just ONCE and for 1 second max. Laptop should start up OK.

6. Once it starts up, go to START MENU/SETTINGS/CONTROL PANEL/POWER SETTINGS and search for the "hibernation" tab. Turn hibernation OFF. your laptop obviously has some problems or lack of responsiveness with hibernation (most do). Use suspend, instead. It is much safer,. faster, and still does a good job of saving HDD and LCD wear. Please let me know how this goes for you, there are other more detailed problems that may be involved here, but I suspect this is most likely.

Notebook not starting and screen remains blank.

this will be easer than you think.
first unplug power cord,pull out your battery and test it by pushing the button on the battery. It will be dead. leave it out. plug in power cord, nothing should work. test your power cord. if nothing than test lower on the cord it might be the plug in that plugs into the laptop. what happens is the battery get to low and the lappy goes into a safe mode . you will need a charged battery to get it to boot.
