Backlight won't turn on my laptop

Q: Backlight won't turn on my laptop

I spilled well-water on my laptop a few weeks ago and immediately removed the power adapter battery and drained the energy from the motherboard I then opened it up as much as I could to dry off what I was able Backlight laptop won't turn on my to My laptop is an Asus U A and I am not entirely sure how to open it up beyond accessing the basics RAM Hard Drive etc Even when I think I ve gotten every screw the casing doesn t seem to want to come off and I haven t been able to find anything online about opening this machine The problem is that after one week of allowing the laptop to dry with good airflow standing upside-down on a wooden desk with a fan blowing I turned it on to see if it would work It worked just fine for about ten minutes and then the backlight started flickering like crazy and went out completely At the moment I am getting around the problem by connecting it to an old desktop screen I had lying around but I originally purchased this laptop for use Backlight won't turn on my laptop at school Any ideas on if I could fix this It definitely doesn t have a warranty anymore so I wouldn t be able to send it in or anything like that nbsp

Hi Aerebes, I really don't fix laptops; only upgrade the standard parts as needed. I did a search and this is what I found so far: http://screensurgeons.mybigcommerce.com/asus-u57a-laptop-led-screen/

Perhaps the video can move you in the right direction. I believe that they are also on YouTube.

Sometimes the backlight won t turn on in the laptop I don t think it s a connection issue Sometimes either the laptop s hardware or the video card is just not turning the backlight on I can see that the display is on by won't (Asus turn F8SP) on sometimes Laptop backlight the way just so faint as to not be recognizable unless in the sun or a flash light is shined on the screen I ve come to this conclusion because the only way to fix the Laptop backlight won't turn on sometimes (Asus F8SP) issue when it happens is to plug an external monitor into the laptop set it as the primary display and then reboot The laptop backlight then comes on and will work find if I disconnect the external monitor The backlight only seems to go off sometime immediately after boot That is WHILE the laptop is posting It shows the American trends bios screen for about second and then the backlight turns off I ve called Asus about this a few times and they always start by talking about an quot electrical reset quot which apparently accomplished on this unit by leaving the battery out for minutes and then booting the machine with ONLY the battery connected This has frequently caused the backlight to stay on a half second longer but beyond that no result Anyone have an idea about this thing It s very frustrating because it makes the laptop less mobile It means that at any time on the road it could be almost entirely unusable since the only way to fix it is to plug an external monitor into it nbsp

A:Laptop backlight won't turn on sometimes (Asus F8SP)

they're pretty clueless...

Every time I talk to them they ask me my model number and serial number... then ask me to do things that aren't possible on this model laptop... I explain that... and then they say "oh, F8's must not have that feature"... Which begs the question of why I bother telling them the model if they're not going to give me model specific tech support?

The problem is weird... I think there's a circuit board that isn't part of the motherboard or video card that's screwed up. I don't mind the problem so long as there's a quick way to fix it on the go that doesn't require a spare monitor.

Hi All, I have a HP ze4240 laptop and can't get the backlight to turn on. The screen is dark, but working. If I put a bright light behind the screen or hook it up to an external monitor you can see the display (windows etc.). I have tried this screen on two different motherboards (1 amd & 1 intel cpu), tried three inverters and two video cables. I checked the actual backlight with an external inverter (the one that came with my desktop ccfl's) and it works fine. If the inverter was smaller I would mount it in my laptop but it is too big to fit. Does any one know what turns the backlight on ? I think it must get a signal from the screen but I'm not sure. Thanks Bill0737

A:Backlight does not turn on anymore Satellite M70-147

> So can anybody with the symptons described tell me what the cause might be?

For me it looks like a faulty FL inverter.
The FL inverter is a small part behind the display frame and it controls the backlight.

Usually the external display should work properly because the FL inverter affects the internal display only...
However, the issue can be solved only by replacement of this part.

I recommend contacting the Toshiba ASP in your country to get this part replaced

And yours should be in the BIOS setup where you can turn on the numlock by default. You will have to look through all the BIOS options to see if you have that option listed in there. But if you looked through the complete BIOS settings and find none then it most likely means there isn't a option to set it by default.

Hey @PROINDIA,  Welcome to the HP Support Forums! You had mentioned that you are having an issue with the backlight when you plug in a USB device or play a video on  your HP Pavilion 15 Notebook PC. You also mentioned that you had contacted the Customer Care Center.  Was it the HP System Recovery that you had done?Did anything change between when the display was working and when the display went dim again?Have you connected the Notebook to an external monitor or TV?Have you tried to see if it happens while you are in Safe Mode?Have you done your Windows updates?Have you tried to do a System Restore back to when it was working fine?Have you gone to your Power Options, Advanced settings and changed the USB settings?Have you done any of your HP Support Assistant Updates? Here is a link to the HP Support Assistant if you need it. Just download and run the application and it will help with the software and drivers on your system that need updating. In some cases, a dim display might be caused by an outdated BIOS or graphics driver.  If you would like to provide me with your Model Number (How Do I Find My Model Number or Product Number?), I can look at the Software and Driver's page for you and see if there are updated drivers available.  If you require further assistance, I would be more than happy to help! Please make sure to re-post and let me know the detailed results of the troubleshooting steps provided. Thanks for joining the HP Support Community!Have a great day!

hi,

I just try to find out how to turn off the displays backlight on my new Z30t.
While processes still are running, just to save power.

Here I have FN keys for putting light up or down, but they do not go down to zero, and there is no key to stop.
I had 6 laptops so far, and all had a FN key to switch off the display for power saving.
So I am somehow scratching my head, how to do here.

Also, I'd like to reprogram some FN keys as I do not need FN sleep and hibernate.
Couldn't find info on that, too.

Some idea? Please help!

thanks, Tommy

A:Portege Z30t - how to turn off displays backlight?

You can use the FN keys in order increase and decrease the display backlight but you cannot shut off the display completely using these function keys.

If you want to disable the display after certain time, I would recommend you to change the settings in the Windows power options.

Go to Control Panel ->Power Options
Here select a power plan page, on the left, click Choose when to turn off the display.
On the Change settings for the plan page, choose the display settings that you want to use for this power plan when your laptop is running on battery and when it's plugged in.

A friend brought me there Toshiba satellite a15-S127. She said the monitor started flickering and the next time she started the system the monitor was blank. I started it up and it does boot into Windows. The screen is essentially black, but I can see the desktop faintly. When I pushed the ctrl-esc keys I could see the shutdown dialog pop up.

So I used the function F7 key to see if maybe that got messed with and the brightness had been turned all the way down. That didn't work.

I'm wondering if it is a backlight gone bad or if there is another software setting that can be adjusted?

TIA

Hello, recently(a week or two ago) a friend of mines laptop, a Gateway MT6728, had juice spilled on it. While there wasn't a problem immediately a week later the backlight didn't come on, but you can still see the image if you hold a flashlight up to it. I took it apart to clean it and see if the video cable had become loose or something, and at first it looked like two of the video pins were missing. But then I accidentally had a magnet too close to the laptop and the screen flickered on for a second since it has a magnetic lid switch, or at least that's the only conclusion I can come to. Is there any way I can test the video cable to see if it's bad or not? Or any other way to test why the backlight isn't turning on?

Thanks

Ok, well I got my multimeter and carefully tested the plug that goes into the backlight inverter board, 2 of the 5 wires have power going through them. I also tested the two wires that go to the backlight and there was nothing there so I guess that means either the port on the motherboard is bad or the inverter is...

Hi,
For some reason, the screens with LED backlights that use PWM for dimming, produce me severe eye strain and nausea. It's not something usual, but it seems I'm not the only one with this problem.
My question is if Dell produces any laptop with a screen that doesn't use PWM. Ideally with 15" display but 17" would be acceptable too.
PWM explanation: http://www.tftcentral.co.uk/articles/pulse_width_modulation.htm
Thank you

My laptop is about 5 years old. When it boots, it works fine, but after a period of time, the backlight goes out. I can still see the screen if I look at it at an angle with a flashlight or something. If I restart the computer, the backlight comes back on. A week or two ago, the light would go out after a few hours of use. Now, it goes out within a few minutes of booting. Is this an inverter or backlight problem?

I have a Dell Inspiron 1535 I purchased in Sept. of 2008 and the Backlight bulb has quit working.
Does anyone know the cost of the Bulb?
I live in the Minneapolis area and would also be looking for a shop to replace said bulb.
Any information would be appreciated.

Actually, it's far more likely that the inverter has crapped out, they go more often than the backlight.

In any case, you can buy the inverters or the backlight bulbs, try a search on eBay for the parts. If you're going to take it to a shop, the cost of labor will be far more than the parts.

I have a Toshiba Satellite A25-S207 When I turn the laptop on I can see a dim screen. but only if I shine a flashlight at the black screen. I was informed it could be my LCD inverter. I replaced the LCD inverter and the screen is still black. I can remote into the laptop from my desktop and see everything else is working fine. Does anyone have any ideal, what I can do to fix? Do I have to replace the LCD screen?
All advice is appreciated

Hello everyone,

My laptop display is always black, but I can see the backlight is on.

My laptop is connected to an external monitor and when I click on Screen Resolution, I see that my monitor's name and my laptop monitor's name, but it's name is now different.

My laptop Display was always called "Vaio". It had max resolution of 1600 x 900.

Now, my Display is called "Digital Flat Panel (1024x768 60hz)" that is totally different than my display...any help?

A:Laptop Display black, but I see backlight

Update the Display adapter driver in Device Manager.

First run all Important and Optional Updates to completion to see if its offered, or another performance update is needed.

Rightclick on the monitor display to see how it is configured, try another. What happens when you choose only the laptop display, or unplug the monitor?

If these fail can you System Restore to before the problem began?

If not then we?ll try to think of other solutions before looking at the screen wiring harness connection.

i have an Acer extensa 2510 serial is NXEEXEA00141910DE93400 SNID: 41906909734. I have checked both these numbers and I keep getting a error on Acers warranty check saying it can't find it in the database,but that's not my problem.
when I try to switch it on, the laptop screen is blank and the backlight flashes on and of repeatedly in less than 1 sec intervals (like a car's indicators). I have tried a hard reset, without battery start, reseating the ram and any other component and cable on the laptop (so yes I have striped it, I work in a pc shop we do repairs) but nothing worked.
so I switched it on and listened to the HDD to hear if its reading or just spinning and I noticed that it sounded like it was in synch with the screen. my thoughts on this is that the motherboard it busted.

There aren't really graphics cards in laptops, they are built in to the motherboard. So, if it isn't displaying anything even when on the bios or start screen, it may be the motherboard that is bad.

A:Acer Laptop Screen Problem-Inverter or Backlight

Normally when the backlight goes out, it will affect the full screen. It can flicker or go out completely. This can be checked with a flashlight held up to a text area on screen and looking for the contrasting image on the LCD. From the way you describe the working then stopping, it sounds to me like the inverter is building up a charge then letting go.

So I was using Windows 8 on my Samsung laptop, but a little while ago I decided to switch it to windows 7 home premium 64 bit since I didn't really like 8.. since then a lot of the build in keyboard functions have stopped working (understandably). Most of the F1-12 keys would control things like volume, screen brightness, wifi connection etc. I can live without using most of them since they are able to be changed elsewhere, but the one thing I can't figure out how to use is the keyboards backlight. it worked when the computer was running windows 8, so obviously it HAS the hardware, but I don't know if windows 7 recognizes that it's there. Any ideas how to fix

New to the forum so Hello everyone.

I understand how to turn down the level of brightness through backlight control but how do I decrease the level even further? The slider in the brightness bar is all the way down (left) yet at nights the light from backlights are too bright!

Couldn't someone please help me out?

Dimming is an option but it still doesn't decrease backlight.

A:Backlight - Decreasing backlight Level more

let's see: there should be backlight and brightness adjustments on the monitor, plus contrast which does affect final light output somehow, plus all those except backlight should be duplicated inside video drivers on your computer and gamma on top of that. If it's a laptop then there should be some combination of Function key and arrows to adjust backlight directly. If you can't get the screen dark enough with all those controls, could be something wrong. If controls are too limited and your environment is totally dark then buy anti glare screen protector, that usually cuts the light coming out probably at least by half.

I bought a new keyboard for my L502x because the old one was beginning to wear out, and I noticed that on the motherboard the connector for the backlight ribbon cable was completely missing the little hinge that locks the cable in place. It wasn't broken, just missing. I have a photo attached, it's a bit blurry but you can clearly see that the little white connector at the top has no locking hinge.

Is there no way to get this fixed outside of just buying a new motherboard? My model was a refurbished one and did not come with a backlit keyboard to begin with, but I heard people say that the connector was there...and yet it still has no option of locking the cable in place, which is very frustrating.
(The keyboard does work regardless, I'm just mildly annoyed that I can't use the backlight)

A:XPS L502x laptop backlight ribbon cable lacks locking hinge

Stupid question but I have to ask, was the connector there when you took off the old keyboard?  Maybe it somehow got stuck on the old keyboard ribbon cable?  If its the white connector i'm thinking of, if its gone its gone and I don't know of any replacement.  You could try electrical tape to hold it in, just so you can have your backlight working.

A dodgy battery could cause a problem. Have you tried starting it without the battery attached?

I have an hp pavillion dv6000 series laptop that won't turn on, when it's plugged into the charger, it lights up when you hit the power button but that's it. It just happened one day, it wouldn't turn on. We haven't spilled anything on it or anything like that. Also, if it helps, it runs vista. I was old it was the motherboard but if it was the motherboard, the light wouldn't come on at all would it?

Hi,Today, I opened my laptop to see the power button flashing on and off on a black screen. The laptop was unresponsive after pressing buttons and moving the touchpad for a while. I then removed the battery and reinserted it, only for it to not turn on at all. I removed the power cord and the battery, held the power button for 60 seconds, reinserted the power cord, and the laptop still refuses to turn on. I inserted the battery again and still, nothing.Any ideas, help, suggestions?Helpful information:There is no light when the power cord is plugged in.Battery was not low last time the laptop was in use.Bought the laptop in April 2015Never had this problem before.Thank you.

Hi @MBuckler?,Thank you for visiting the HP Forums! A great place where you can find solutions for your issues, with help from the community!I came across your post about the Notebook, and wanted to assist you! I have looked into your issue about your HP 15-f039wm Notebook and it does not turn on correctly. Try performing a hard reset. When performing a hard reset please note remove any and all USB devices. Disconnect all non-essential devices.Here is a link to computer won't start for Windows.You can do a system restore. System restore will help if something automatically updated and did not go well on the Notebook.Please let me know how this goes.Thanks.

Hi, I I used it a couple of days ago, and when I started it it booted and everything up to the point where it asks my windows password. After that it turned off. I figured it's just dead battery, but when I tried it today it just wouldn't start. I tried holding the power button with the AC on and no battery, with the battery and no AC but still nothing. The laptop is about 2years old. Thanks

My Gateway laptop won't turn on. I used it last night with no problem. When it is plugged in the light on the front shows that its plugged in. When I try to turn it on the other light will flash along with lights by the mouse and then it goes off. The screen never turns on. I haven't had any problems with it up to this point. The computer is less than 2 years old.

I have a gateway MA3 and I had it about a year and then one night my husband was on it and he said that it went crazy so he through we had a virus and shut it down. I tried to boot it back up and it would not turn on. The HD light would flash and the CD light would flash and both would make a noise. Do you think it is a bad HD, CD drive or motherboard?
 

A:Laptop won't turn on

No way to tell for sure from what you have told us. It could be any of those... Hard drive, memory module, power adapter, DVD drive, or dirt, hair, fiber and heat.... or even a power switch
First, check carefully for any lights or noise when you depress the <ON> Button. Then gently wiggle the plug from the power adapter where it plugs into the laptop as you depress the <ON> button to see if any lights or noise happen.
You can buy a new power adapter for about $11 to $22 on eBay, but that would take ten days to arrive. Can you borrow a power adapter from anyone... anyone that fits will be good enough for a brief test.
Second, do the sniff test with the covers off, as you try to detect a burned odor.
Third, you remove one memory module and try to turn on with the other. Then change the two around and try with the other module.
Some gateways have had trouble with the power adapter, but it is not easy to test at home. A good technician can use an instrument to test the power output. The hard drive should not be dying this soon unless it has had some impact.
Fourth, you can remove the hard drive from the section on the base of the computer, you can test with another or test yours in another laptop of similar configuration.
In short, get a tech smart person to look it over for you... of have a repair shop do an analysis... which will likely cost about $40

Any messages or BIOS splash screen showing on the display?

Is the display backlight lighting up? If not, can you see any screen content if shine a strong light on the screen?

If you have an external display connector on the laptop, do you get anything on an externally connected display?

If you leave the computer turned on long enough do you get any Windows start-up sounds?

Any chance you can let us in on the brand and model number of the computer?

Hi,

To eliminate the battery, remove it & power up on mains. If it drops out then it will probably be overheating?

I have a Lenovo ThinkPad SL500 and it's relatively new. A year or so. I shut it down before I left for the weekend and when I came back to turn it on, it just wouldn't.

It's plugged into a surge protector that I know works cause the printer is also plugged into it and is working fine.

The little battery light does NOT even light up at all with it plugged in and when I press the On button NOTHING happens.

Just absolutely black everywhere with no signs of life or any light.

What do I do?

I have a Compaq v5310us laptop, and the fan turns on and off very often. Like every 30 seconds to a minute or so, stays on for about 20-30 seconds, then turns off. I was told that the fan can run often because stuff is so close together inside, but this seems like a lot. Is this normal?

I took out the battery, and after I put it back in I tried turning it on and it wouldn't start. I tried the hard reset in which you hold the power button for 30 seconds to a minute after taking out the battery and the charger, but it didn't work. When I connect the charger, the light that indicates it's charging turns on. And when I press the power button it makes a barely noticeable noise. Other than that the laptop does no respond.

Do not plug it into a power strip, surge protector, or secondary power source as this could cause and issue.Have you tried reseating Memory and the HDD? Click the Thumbs up to give me a Kudos high five, just to say thanks for trying. Thanks.

I m not sure (sometimes) turn on Laptop won't if this is the correct place to post this thread but here goes Two days ago my laptop ToshibaM x satellite was working fine Then it froze while doing normal internet searching on eBay I turned it back on and once Windows loaded it froze Twice more and the same thing happened The fourth time it began to load but then a screen that looked like a red and green curtain came up reminiscent of what would happen to my Nintendo when there was too much dust in it Anyway Laptop won't turn on (sometimes) since then sometimes I will hit the power button and the fan will Laptop won't turn on (sometimes) whir but the screen stays black Sometimes it will load up and work for about seconds before freezing Once I had it loaded and working and when I went to plug it in it froze But right now after two days of this I m actually on it making this post and its working fine knock on wood I guess my question is does this seem more like a hardware or software problem And why is it all of the sudden working fine As you can probably tell I m not very proficient with computers so please bear with me For security I run Norton anti-virus Mike nbsp

A:Laptop won't turn on (sometimes)

Just wondering if you have done a system restore lately. Occasionally you can have a conflict with existing files.

ok first get some canned air, and lightly blow out the laptop to make sure it's not just dust getting into things.
Now, to be on the safe side....
Do you have anti-spyware software installed on your computer? I would eliminate security stuff before you do anything else. I suggest to run at least two different anti-spyware programs: I personally like: Windows Defender by Microsoft, and AdAwareSE by Lavasoft. You can download them for free at www.download.com . They are both very user friendly, and easy to set up. Also, do you have a firewall running? (besides Windows firewall?) There are several decent free firewall available. You can search on the site that I gave you. I stick to Zone Alarm; it works ,it has history, and it's easy to use. But you choose what you like if you don't already have one.

After all those programs are installed:
1- run your antivirus program if it hasn't been run lately; also make sure you update first, by clicking "Live Update"
2-run AdAwareSE, first updating it as well.
3- Windows Defender should scan on its own after installed. If not, you can run that too.
4- Go into Control Panel ... then Internet Options. Delete all temp and unecessary files.

Restart your computer daily (especially if you do a lot of internet or gaming)
go to: Start > Turn off Computer > Restart **** This should be done with ALL computers, not just laptops

The above should help to keep your computer healthy. Hope it helps your problem. Good luck.
