Light on keyboard and screen DIMMING ON AND OFF

Why does the lights come on and off when I'm typing it P**s me off. I realize my hand must be covering the sensor but how is it situated on the keyboard

Hi Fats1973: Yes, the light control is a bit of a pain isn't it? I have downloaded and use "LabTick". It is great little control program to set the light level of your backlighting. It can be found at: http://labtick.proculo.de/

Try to start up in Safe Mode. It uses a "one size fits all" display mode, runs one pass of Disk Utility "Repair Disk" as it starts up, then loads with minimal extensions and presents a login screen (even if you normally auto-login). It takes five minutes or more.
If you get a picture, use System Preferences > Displays ... to change your screen resolution at least once.

Appreciate any help

Hi having the same problem with iMac 17 isight. Will not startup and only the white light flashes on and off. No sound. Removed front cover and tried start and same results, but I could see that the fans would sort of shake as the light flashed. Tried replacing the power supply and the same results. Can't us the AHS application, because the computer can't startup. Anyone with an idea?
Thanks

My screen dims then turns off (sorry my camera is not that good )
Works normally from here ^
then it turns like this (with BEEEEEP noise)
^ Like that my screen is bright on one part of the screen and the other part is dark. It also makes this beeeeeeep noise. after this, screen turns black.
My computer is ON and running though. It's just the monitor that goes off.
Any way to see what is making this problem?
Thanks. By the way, I've already done the manufacture reset. It's obviously a hardware issue.
I'm so dissapointed with HP products.
It's been 2 1/2 years since I bought this computer and it failed TWICE already.
One time Hard drive failed, now my monitor goes black like this. -_-

Blue screen on c7280 all in one reads b851fe84. lights flicker on and off. will not turn off.

HP Photosmart C7280 All-In-One printer. Operating system is Windows XP. This has happened sporadically over several months. A few weeks ago, I inserted new ink cartridges and that seemed to stop the problem. Now, it has returned. The on/off button will not turn the printer off. The photo-menu, print photos, auto answer, on/off button, plus a light near the card slots all blink on and off. The PhotoSmart Express displays a blue screen with B851FE84 written on it. On occasion, I have received other blue screen messages but they appear for just a second or two. I believe one earlier today was B01B17FC but it only appeared for a second or two so it may not be correctly recorded.

I just bought a Macbook pro and the keyboard lights flash on and off. What's wrong? do I need to take it back?

ahhhh help!

you can switch off the automatic lighting of the keyboard by going to system preferences then keyboard and uncheck 'automatically illuminate keyboard in low light' . after this you can control your keyboard light by using the buttons F5 and F6 at the top of your keyboard

(SOLVED) Keyboard lights go on and off and then Xorg crashes

Strangest thing happened when I turned on my computer this morning:
As I was doing my usual business (only Firefox running on top of Gnome), keyboard LEDs started going on and off (e.g. scroll lock and caps lock turn on, num lock off, then I press num lock, and they go off, and then one of them reappears again, etc - no pattern), and then Xorg just crashed.
I'm running the latest kernel with latest nvidia drivers.
This is what Xorg's log shows:
Backtrace:

Fatal server error:
Caught signal 3 (Quit). Server aborting
The entire xorg log is here: http://pastebin.ca/1823592
After the fact, everything seemed to be working fine again. Xorg restarted and keyboard was behaving.
Any ideas what this could be? It never happened before...

I'm not really sure, but it seems that vmware workstation + evdev was the culprit.
I uninstalled Vmware Workstation and everything seems to be back to normal. I couldn't bother to check which modules were loaded and how was this confusing to Xorg, but it's "solved" now.

How to turn of light on "On and Off" on NB200

I have a mini nb200 and there is a light on the power on and off button in the middle, and I wondered if it is possible to turn that light OFF!
It's a very annoying light! :P

It's only one solution to this.. Take off the batterypack. Then you will see 3 screws. Open them, and the plastic piece with the powerbutton will fall off. Then just crush the litle white led with at screwdriver or something. Then put everything back, and you won't see the light anymore!

My LED light turns on and off on its own, how can I fix this?

I dropped my phone today and my LED light on the back by the camera turns on and off randomly. I've dropped it before today and it just now started doing this. How can I fix it or do I have to bring it in to a Apple store?

The phone is probably broken. You will have to take it to an Apple store for repair or replacement.

HT3964 My MacBook Pro i5 Dual Core has a hardtime waking up when the computer is put to sleep and only when it goes to sleep and has been asleep for a while. The indicator light flashes on and off for a while and then freezes. I've done an SMC reset once.

Does any one have the same problem with their MacBook Pro i5 Intel Dual Core? If the computer goes to sleep (not the screen) and is asleep for a while, when I try to wake it up it doesn't respond. I have to power it downn and restart it and sometimes it takes two or three attempts. Otherwise it works fine. I upgraded the memory to 8 GB. That is the only alteration doen to it. I've performed one SMC restart and now it wakes up but it takes a while and a gray screen shows up. When I insert a DVD it won't start automatically I have to start the application in order to see it. Any suggestions?

HT3205 Green light flashing on and off every second

What is indicated by the green light on the charger going off and on every second?

Usually it is a charger or battery issue.
Try a SMC reset:
http://support.apple.com/kb/HT396
Use the method which applies to your Mac, a battery you should remove (most likely)
You can also check the battery status by clicking on the Apple logo and About This Mac, More info or system profile (depending on which oSX you are using as it is not in your profile) Power in the left side bar and check battery health and other stats.

Could be an early retirement problem. There is no fixed lifespan for anything, as you know. Find a friend with a keyboard and test that in your machine. That will show if it is your keyboard or your computer. We can progress from there.

Black Screen, but sleep indicator is coming on and off

I've got pretty old MB that was bought back in 2007, and it's been working ok up until today. All of a sudden I can not boot it, the screen stays black. Whenever I turn it on the screen flashs for ~100ms and then remains black, at the same time the sleep mode light is on and off not gredually fading in and out like when it is in sleep mode but sharply. Safe boot didn't help, PRAM reset didn't help, booting into the firmware (CMD-OPT-O-F) didn't work as the screen stays black. . I can hear hard drive working but other then that I see no signs of life (even caps lock and num lock keys don't get highlighted when I press them)
Is there anything else I can try, or is that it?

If you haven't tried, Reset the System Management Controller (SMC)

Screen Dimming still - after unchecking 'ambient brigthness settings

I've turned off the ambient light settings under display, but still the screen dims then turns off, while on AC power.

Please help.
Thanks!
