Trackball and keyboard light are off

I have a blackberry curve 8310 on AT&T and just downloaded and installed the new OS 4.5. Everything is working fine but I noticed the trackball and keyboard lights are not on and I cant figure out why. Anyone know?

I'm having the exact same problem, upgraded to 4.5 and now the trackball and keyboard won't light up(although they do light up when booting the fone). What did you do to fix this?

anyone else having a similer issue? is this software related?

That seems like a loose or failing cable.
You could try a SMC reset: http://support.apple.com/kb/ht3964 to elimate the controller.

You could try running the Apple HArdware Test, not always definitive however. If it shows an error code report back.

Keyboard clicks and lock sounds are off even though the settings show them as "on". How can I get them back?

Use the volume buttons on the side of the phone. Personally, I find it's better with those off completely.

Error message - Attention and ready lights are on

My printer has stopped working.
I have an error message where both the Attention and ready lights are on.
In the user manual, it states that The product has experienced a fatal error
from which it cannot recover.
I have tried turining off and on again, and the error persists.
We had a power outage, and the problem started after that.
What should I do?
Is there a fix to the problem?

Hi @TomRem ,
I see that the printer is in a error code, the Attention and Ready lights are on. I would be happy to help you.
Here is a document with the error message and the full reset for the printer. Please go to Solutions for Attention and Ready lights on. Blinking Lights on the HP LaserJet Pro CP1025 and CP1025nw Color Printers.
Make sure the printer is connected directly to a wall outlet. (don't use a power hub or a surge protector) This ensures the printer is receiving full power and may help this situation.
Since this issue happened after the power outage, I would suggest to try another power cable. One off a monitor will fit the Laserjet, just for testing purposes. Maybe try another outlet in another room on a different breaker, just to rule that out.
If the issue continues, please call our technical support at 800-474-6836 for further assistance. If you live outside the US/Canada Region, please click the link below to get the support number for your region.

Hello my battery power has a x on it and the lights are not working and its making a noise - Please assist

Hello my battery power has a x on it and the lights are not working and its making a noise - Please assist

The Battery icon with the "X" indicates that your computer does not detect a battery and is operating on electrical power from AC since your computer is plugged in. If your battery is installed but not detected that indicates a problem: 1. the battery is dead; 2. the battery connector is not functioning properly. You mention that there is no response from the indicator lights so it could be either of the two possibilities. The noise is not a good sign. Best to shut it down safely while you can to prevent any possibility of damage and get it to an Apple Genius Bar or Authorized Apple Service Provider to discover the nature of the problem

Can someone hack into my MacBook Pro even it's not connected to the internet and both Wi-fi and Bluetooth services are off?

Hi,
Need to know if someone can hack into my MacBook Pro even if it's not connected to the internet and both Wi-fi and Bluetooth services are off? Can someone enter my system even if the settings at System Preferences > Sharing are all off?

Yes,
Through Bonjour, Apple's open source zero configuration networking.

And you can't turn it off or your computer won't work, however saving grace is the hacker has to be pretty close to your machine to do it.

Problem with Battery and Keyboard Light

First off, sorry if this is in the wrong section. This is my first time on these forums.
Just today I was skyping my girlfriend on my Macbook Pro (that I got in the summer or 2010). I have SmcFanControl installed and I regularly use it to monitor/increase my fan speed. As I regularly skype and play WoW on this computer, my computer temp often sits around 160-170 degrees F.
Today it was at around 170 and I had it on my lap. I sat up and jostled the computer a little and it shut off. The power cord light, which was green, immediately turned off. I tried unplugging it and plugging it back in and it stayed off. The computer wouldnt restart for about 30 seconds. Finally after hitting the power button several times it turned on.
It worked fine for 10 or so minutes. I assumed I just moved it too suddenly, although I have never had a problem with that before. Then, I moved again and it shut off AGAIN. It took another 30 seconds to register the power cord and to turn on.
This time, when it booted up, it said my clock was set to a date before 2008, althought it was still at Feb 16, 2011. Also, as soon as I turned it on, the fans were going full speed (as loud as when i have SmcFanControl set at 6200 rpm). I opened SmcFancontrol and it says my computer's temp is at 32 Degrees F and 000 rpm, which I know is not correct. I can't change the speed of the fans and the temp of the computer hasnt changed at all.
Also, my battery icon has an X through it and says "No batteries available" "Power Source: Power Adapter." The green light is very dim on the charger.
AND on top of this, my keyboard lights no longer turn on, even pushing F5 and F6. I am in a dim room so they should auto turn on.
I am afraid that I may have overheated the computer, but I was wondering if anyone has any advice. I was thinking of opening the back up but I dont have a small enough screwdriver at the momment. I also tried doing the "top -u -s3" command to check cpu% and my highest one is Firefox around 10-15%.
Any help would be appreciated. I'm thinking this is gonna require a look at the Apple Store, however I am an out of state college student and I'm not returning home for another week and I need my computer for assignments.
Sorry for the wall of text. Thanks in advance.
P.S. My computer is up to date.

SMC reset works best with anything that relies on power for the machine. When it comes to batteries SMC reset and PRAM usually do the trick. Also a lot of people miss this, do not plug on the top plugs use the lower plug.
As for the temperature on the lap, expect a lot of heat, the computers are designed to lay on flat SOLID surfaces. The underbelly on aluminum chassis laptops act as a heatsink. In addition the rubber feet keep the product high enough so air can pass through and help cool the system.
As far as the adapter you can have AppleCare send you without waiting a week for it. If it is an obvious hardware problem they may do an exception for you if you are out of phone support. Highly recommend APP for the phone support. You would have a battery on it's way to your current location in a couple days!

Update causing video sound and keyboard light to not work, oh yeah and camera.

Drivers are missing for camera, graphics,keyboard light,and sound after update 10.7.3

The method to seek warranty varies by location and other factors...so there is no way to tell you exactly what your warranty method is. Instead, you need to review your original purchase contract for the device...in that contract, your warranty terms and methods will be documented, and that is what you must follow. Since I cannot see your original device purchase contract, I cannot know what it says...only you can see your contract, and therefore know what it says. If you are unsure, then talk to the seller (to you) of the device and ask them what your warranty terms and methods are.
Occam's Razor nearly always applies when troubleshooting technology issues!

Macbook Pro screen and keyboard lights problems

Hi there, I have a macbook pro 15'' late 2011. Lately I realised that the screen does not dim when in a dark room and the keyboard lights do not work either. The keyboard keys work for dimming and lighting the screen, but it does not happen automatically. As for the keyboard lights, pressing the F5 and F6 buttons brings up the image of keyboard lights and they seem to be increasing and decreasing, but in fact nothing happens and the keyboard remains without any lights.
Any suggestions?
Thanks!

You should also ask this in the MacBook Pro forum. This is the forum for the 13” white and black plastic MacBooks without lighted keyboards that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

Unresponsive MacBook Air with fan running and keyboard lights.

This is a weird one: I opened my MBA today to find it dead, ie no lights or sounds. I initially thought the battery was empty so I hooked it up to the power adapter. No light on the plug. After realising that the power adapter was ok I did an SMC reset, which started the fan and the keyboard lights. Other than this there is no sign of life. I am unable to start or stop the machine and there is no effect when using the power button (Ctr-Cmnd-Pwr).
Any bright ideas out there?
Many thanks in advance...

My mac keyboard lights are not working

hi..
i m using mac pro 13... suddenly lights of my the keyboard is went off...i restart the machine by nothing happen.. the problem is still same only..plz help me out...
thanks,
jatin

What do you have in System Preferences, Keyboard under "Adjust keyboard brightness..."?
What happens when you push F6 to increase the keyboard light intensity?
Normally, if you have that checked, the keyboard lights only come on if the ambient light level is sufficiently low. They go out when the light level gets high enough. (Sorry if I am stating the obvious.) The sensor is at the top of the display, where the camera is. If you cover the camera lens, do the lights come on? (You may have to turn up the light intensity with F6.)
Try unchecking that preference box.
If nothing else works, try resetting the NVRAM.
If that doesn't work, you probably will have to take your machine in for servicing.

13" MBP died. Only a black blank screen and blinking lights are visible. Any ideas??

My friends MBP died the other night. He put it on sleep mode one night and the following morning, and when he went to turn it on the following morning it would't. Only a black blank screen and blinking lights. There is no sound or anything. BTW it is a mid-2010 MBP, no added hardware, everything stock. It wasn't custom configured, and I believe he upgraded to Lion earlier this year. I read somewhere that depending how quickly the lights are blinking could indicate a specific problem. Is this true? He is planning on taking it an Apple store, but figured we would try here first since it is a bit of a drive, and the warranty has expired. Any help would be greatly appreciated. We are just trying to get an idea of what we are dealing with. Thank you!

Looks like hardware problem.
Apple can fix it. Take it to Apple as soon as possible.

IBook G3 Won't Chime - But Keyboards Lights are ON

My ibook was working fine, then I closed it so I could bring it into another room and then the computer became unresponsive w/ a black screen. I tried resetting the power management as instructed in the Apple Support and the only thing that happens is the power seems to be on because the green keyboard lights light but it's as if the computer never boots (no chimes and cannot hear volume up and down noise and cannot open the disk drive). Any suggestions? I've had the logic board replaced TWICE. Highly annoying! The last time the computer was sent back to me as a clean slate so I lost everything. I don't think it's the Logic board this time though because the two times that the logic board went bad, I could always here the reboot chimes and the volume indicator sounds. Any suggestions would be greatly appreciated. Thanks in advance.
ibook G700mhz Mac OS X (10.4.4) Logic Board Replaced TWICE

Have you tried resetting the PMU?
The PMU (Power Management Unit) controls the charging function, so resetting it may help.
If resetting the PMU doesn't help, then I would recommend trying a known good adapter.
The iBook is acting like my husband's did when the power input (DC-in) board was damaged, so if resetting the PMU didn't help and a new adapter doesn't work, either, you may be looking at needing to replace the power input board (the part of the iBook which includes the adapter port).
Please let us know how things go for you.
