Dell Inspiron 17 7737 :: Keyboard Backlight Turn Off When Screen Turned Off

Jan 25, 2015

On my old XPS, when the screen turned off, the keyboard backlight would turn off with it automatically. My new Inspiron 17 does not do this, and I can't find anything that seems to control the behavior. Is there a way to do this?

Alternately, is there a software solution to control the keyboard backlight?

Apple :: 13" MBP Screen 9CC2 - Backlight Was Not Strong Enough To Overpower The Reflections

Jul 23, 2009

Got my MBP yesterday. It came with a 9CC2 screen, which is supposedly AUOptronics.

Contrast is very high, I reckon above 800:1. Colors and viewing angles are very good too. It has one problem: brightness.

I used it outside with sunlight but the backlight was not strong enough to overpower the reflections. My MBA was much brighter, and also the 9C89 screen on my first uMB was brighter.

When I'm working inside the house during the day I'm usually on 1 or 2 stripes from the max.

It's a not a huge problem for me because I did not really plan on keeping it for long but if I buy again I'll probably try to get another screen. Expecially the MB April 2009 screens interest me. I've never seen them in real life though.

Here are some pics of it next to an Asus 1101HA which was measured at 129 nits max by Notebookjournal.

The first three are on full brightness, than half brightness. Keep in mind that photographs can not really give an accurate impression of brightness levels.

Apple :: LED Bulb Life - Screen No Longer Even Turns On Which Means The Backlight Is Dead

Jan 9, 2009

In the past, I used to have an hp pavalion laptop. I usually kept the screen at a little past half brightness and in 3 years, the screen no longer even turns on which means the backlight is dead. The same thing is true for my mother's 17 inch lcd monitor. Now I realize that this may just be bad luck, but I don't want to risk anything with my new macbook.

What's a "safe" level to leave the brightness at? And is the LED long lasting? Is it expensive to replace? I hate dim screens but I don't want this screen to die that fast, I want to make this last AT LEAST 8 years.

HP Pavilion Dm4 2033cl Display :: How To Turn On Keyboard Backlight

Nov 8, 2014

I am pretty positive that my laptop does have a backlight. However, I didn't need it at the time and I shut it off. But now I can't turn it on. I originally remembered adjusting it through the power options and that there was a little slider to adjust the brightness of either the screen or the keyboard.  I could have been wrong though, since I no longer see the second slider for the keyboard brightness. I have tried everything I could find to get the light to turn on. I used the mobility center but there is no keyboard option. I have tried the fn + spaacebar, fn +f5, and my keyboard does not have a specialized key to adjust the keyboard backlight either. How to turn on the backlight?

Lenovo Yoga Flex :: Keyboard Backlight Will Not Turn Off On Y2P

May 20, 2014

I've owned my Y2P for the last 3 or 4 months now.  Keyboard backlight always turned off/on with Fn Spacebar just fine... until today.  Fn+Space just gets the keyboard backlight to flash off for a second, and then back on.
 
Also I checked and all of the other Fn keys work.  Also the Caps Lock light doesn't come on either.
 
And if that's not all, My power indicator light is amber even when fully charged.  (solid, not blinking)

HP/Compaq :: Cq60- Using An External Monitor And The Monitor Refused To Turn On From Standby

Feb 10, 2010

i dissasembled my presario cq60 and when i put it together the monitor won't activate.

i tried using an external monitor and the monitor refused to turn on from standby, a safety feature of the monitor. the small card in the underneath with 2 wires leading 2 the monitor, (i assume that is the laptop version of a graphics card) is fine, inserted properly, and i had a slight issue with the plugs fitting, but that was soon resolved.

Lenovo U/S Series :: IdeaPad U530 Touch - Backlight For Left Most CTRL Key Stopped Working And Turn Off Completely

Jul 21, 2014

Before the end of 2013 I bought an Ideapad U530 Touch for school and it's been working fine up until a few days ago when the backlight for the left most CTRL key stopped working and shut off completely. Every other key on the board is fine, except for this one. Is there any easy to fix to this problem, or do I need to send the entire computer back?

HP/Compaq :: HP Nc8430 (Resuming From Standby-Blank Screen)

Oct 2, 2009

I have Windows 7 RTM running on my nc8430 laptop. It has been working great. The only issue is a standby problem. If I put the computer to sleep via the FN-f3 combo it goes to sleep like it should and wakes up like it should. My power profile is set to put the computer to sleep after 10min of inactivity. If after 10min I let the computer go to sleep on its own, upon resuming it from standby I get a black screen. The computer is on and everything is working with sound, just no screen.

I am assuming it is a possible BIOS problem or video driver problem. I have the most recent of each and have tried different video driver versions but no fix.

Dell :: E6400 LED Backlight Screen

Jun 22, 2009

I got my E6400 last week and I found that everything all right except the color of LED screen, it's awful.

The color of the screen is pale, i had tried to calibrated the graphic settings but it doesn't improve too much.

Also, i saw some posts here said that the LG screen is better than the Samsung screen, but I can't agree with that because my screen is LG.

Is it normal for LED backlight screen that the color is more pale than the CCFL backlight screen or just the screen of mine had some problems?

Apple :: Do All Unibody MBP Have The Backlight Unevenness

Feb 13, 2009

Unfortunetely I received a unit with uneven backlighting on the screen (9C84), with a few column of light bleed towards the center that goes from the bottom of the screen and reaching up past mid screen. It is not visible with normal use, but on dark solid backgrounds, or when watching movies with dark scenes, it is definetely there.

Do all unibody MBP have this backlight bleed problem? Are there ones out there with perfectly even backlighting or atleast with very very minimal bleed? Just trying to find the statistics of this problem. I will be going to the Apple store this weekend to check out the MBPs they have on display to see how widespread is the problem.

If this is indeed a problem for all unibody MBPs, then I wont even bother and just accept what I have on a premium product.

Dell :: Inspiron 5160 Screen Backlight

May 15, 2009

First off before I get into the problem I want to say that I am an experienced computer technician having worked on hundreds of laptops in the past. So I'm very familiar with the problems and solutions for them.

I just want that disclaimer to be up front that I'm not a rookie seeking laymans terms or solutions.

Anyway, that aside. A customer dropped off an Inspiron 5160 last week. The system wouldn't half power on he said so after testing, I determined that the AC jack was 'broken'. Sure enough after disassembling the computer I could see on the bottom of the motherboard where the AC adapter had been knocked loose.

I replaced the motherboard and immediately noticed that the screen would display the BIOS Dell logo for about 5 seconds, and then cut off.

With a flash light I could see the data images on the screen, just no CCFL light from the bulb to brighten the screen.

Sony :: VGN-Z540 Screen Backlight Turns Off

May 3, 2009

Problem with my 2 week old sony vgn-z540 laptop.

Heres the problem:

When I try to use the brightness level in between LOW and HIGH, my LCD backlight would go off, and the screen would be dark and almost not visible at all. There are also vertical bars at random spots, stretching from the top of the screen to the bottom of the screen. I can only use it with either LOW setting or HIGH setting, nothing in between.

This problem just started on its own. I have not installed anything such as drivers or programs. No updates(was updated after the problem occured to try to fix it).

I love this laptop to death and has been the best laptop in the past 15 years. I would hate to see it go so I need this fixed.

I will update later with pictures when it gets dark here b/c the pictures now are not showing up with the bars.

HP Display :: Pavilion G6 Screen Backlight Flickers

Jan 19, 2015

my laptop screen backlight goes off, when I rest my hand on the left side of the touchpad. The darkening of the screen can be also reproduced when a small pressure is applied on the case just above the ethernet port or above the headphones port.
When the screen goes dark, I can see that everything is running normal, if I shine on it with a lamp or strong light. The resulting effect seems to be the same as if I would have lowered the brightness to minimum.
 
When I don't press the area described above, the screen is just fine. I am sure this problem is not software or OS related. I googled it a lot and my guess is lose connection on the inverter?
 
One last thing - idk if related - sometimes, when I boot up the laptop, the backlight is turned off and I have to adjust it by pressing F3.

i assumed the screen was knackered, but i installed a game a few weeks ago and it brought the display back to life, only for it to look crap again when i restarted. this also happened when i did a clean install of vista, only for the display to go bad when the updates installed.

i have tried many times, but have been unable to replicate this...............

Apple :: Macbook Is Dead - The Screen Doesn't Go Grey The Sleep Light Doesn't Turn On - Fan Doesn't Start

May 23, 2009

My friend's macbook (white plastic, 2.0, napa/core2 before santa rosa platform) isn't starting, and I have no idea why. He initially asked me to replace the top and bottom casing. I accepted, and ordered the parts. Around the time they were supposed to come, I took the computer apart completely (required for the repair), but one of the parts was delayed, so the computer sat splayed on my desk for a week. I didn't exactly stack textbooks on it, but it also wasn't covered in anti-static wrap. So, now, I finally got the part and put it back together, and the computer doesn't start. At all. The screen doesn't go grey, the 'sleep' light doesn't turn on, the fan doesn't start - nothing. The magsafe light is green, so the power is going in. It's also worth noting that I have no battery for it, so it's all on A/C.

Does anyone know what's wrong? My two hypothetical solutions are (a) I need a battery, or (b) the logic board is dead due to static.

How likely are each of these scenarios - especially the logic board one? How possible is it that it was static overloaded?
