Keyboard & Mousepad Just Freeze - HELP PLEASE

Hey all,
Well, maybe it's a known issue but still I couldn't find any solution for this. I have a MacBook Pro 2.53 Core 2 Duo, 4GB. Running Leopard OSX. During working around with the mac and internet, the keyboard & mousepad just freezes - sometimes I wait a while (30-40 seconds I guess) and it comes right back, but sometimes (and lately most of the time) it freezes and doesn't come back no matter how long i wait for it, up to a point where I have no choice but to restart by holding the power button long enough. Besides the fact that this is very unhealthy, any work I got is just lost (if unsaved ofcourse).
ANY help would be great.
Thank's alot.

Hi
Have you had a little spill recently? One you may not know about perhaps? It's also possible the Top Case has developed a fault? Or at least the trackpad and keypboard parts of it has.
Something you could quickly try is create another admin account. :ogin with it and see if the problems remains. If it goes away login with your account and create an untitled folder on the desktop. Navigate to your /Users/Home/Library/Preferences folder select all the files except for com.apple.mail.plist and com.apple.dock.plist and put them into the newly created Untitled folder. Restart the mac. If any application or utility thereafter moans about a missing preference file/.plist you can easily pop it back in.
If there has been no spill and if the problem persists and if the laptop is still under warranty take it to your nearest Apple Repair Specialist. They should be able to diagnose and troubleshoot it further for you as well as replacing the parts.

I keep losing my connection from iMac to keyboard and mouse any help please

I keep losing connection between imac and my mouse and key board.I then have to power off and reboot to get connection can anyone help please!!!!

Hi
Update date for anyone who ha suffered with the problem of losing connection to an ext HDD.
For me, the solution appears to have been achieved by making use of my old 802.11 b&g Airport Extreme base station and my new 802.11 n Airport Extreme Base Station.
My network is now setup as follows:-
Airport 802.11 n - 5GHz
Macbook Black
Apple TV
Time Capsule
Airport Express Base Station
Airport 802.11 b&g - 2.4GHz
Playstation 3
Xbox 360 Elite
Nintendo Wii
iPhones
iPod Touch
Canon Wi-fi Printer
iMac G5
Sony VAIO TX2P
I connect my ADSL line to both AEBS by ethernet, changed the settings and this has dramatically improved my connection reliability and speed when streaming movies and/or music.
Through trial & error, I have also discovered that the other problems that I have are connected to situations when restart my Macbook after a shut down or restart and my iPhone is connected. This causes iTunes to start up but due to the restart, the ext HDD is not ready and therefore, ITunes opens its local library - I now just try to remember to use the Option key to choose the library. Finally, if the laptop just runs out of juice, the ext HDD doesn't have the chance to have a friendly handshake before losing its connection. When I restart, the connection does to the HDD fails and I have to restart AEBS
I hope that helps anyone with similar problems or who wants to make the most of their fast 802.11n equipment by making is use of that kit that was maybe considered redundant - by creating a dual frequency network that maximizes speeds on 802.11 n whilst allowing use of the legacy 802.11 b&g devices.

MacBook air keeps freezing. help please!

I have recently purchased a MacBook Air and every time I go to watch something on Skygo it keeps freezing. There's nothing I can do. No buttons work, I can't reset it and if I shut the screen down it remains still running. The only option i'm left with is to wait until the battery runs out then I start it up again. This has happend 3 times now and I have only had the Mac just over a week. Can anybody help me please?

To perform a forced shutdown, hold the power button for about 10 seconds. If this is the only time your computer is crashing I'd suggest first using a different browser, maybe FireFox instead of Safari (or Safari instead of FireFox). Since I don't know how these videos are delivered (Flash, QuickTime streaming, etc) I can't make any suggestions there but you might have some luck with Skygo's tech support.

Unknown kernel option and a freeze, help please!

Hi,
Reopening this thread - I had to re-start at boot three times today. The kernel freezes up on boot, right before I'm supposed to load the console fonts. On boot, my fonts change, so that could be the point where the thing freezes...
Uname -r gives "2.6.36-ARCH", possibly this started after the last update, I dunnow...
What's the next step I take? Except a panic, please, no more panic!!! Please help, thanks.
Thor
Edit : this is what it said :
unknown boot option+0x0/0x19f
Any clues?
Edit - once up and running, the thing keeps going. Udev is 165-1 according to pacman.log...
Edit - This was reported (today?) as a bug ( https://bugs.archlinux.org/task/22343 ) so, all I can say is "go-developers-go!!" and I'll just w8 the ride, I guess...

Hi,
I too just recently had a Kernel Panic. I think mine was related to video. Yours looks like there are hints to storage problems? Look at these:
dependency: com.apple.iokit.IODVDStorageFamily(1.4)@0x6e4000
dependency: com.apple.iokit.IOSCSIArchitectureModelFamily(1.4.4)@0x52a000
dependency: com.apple.iokit.IOStorageFamily(1.5)@0x4e3000
dependency: com.apple.iokit.IOSCSIBlockCommandsDevice(1.4.4)@0x6eb000
dependency: com.apple.iokit.IOCDStorageFamily(1.4)@0x6da000
com.apple.iokit.IOSCSIArchitectureModelFamily(1.4.4)@0x52a000
Do you have SCSI drives? I don't even really know how to read these as I am really guessing based on reading previous posts and seeing other logs including mine. I never had a kernel panic until I installed 10.4.4 So I suspect there is maybe a bug in 10.4.4, maybe in the video driver or my Graphics card is croaking.
How long have you been having Kernel Panics? Since what version of the OS?
Here is a link I have seen posted on here several times.

It's the Quick Selection Tool in Photoshop Elements 9 and I'm trying to get the background and make it another layer so I can even out the color of the background then bring down the transparency. Not sure if that makes sense. I'm new to this.... Sometimes the area it will grab can go ...not fast.. but not slow. Sometimes it's like it's just messed up and literally takes 30 seconds to process each move. I rebooted my computer and re opened it and it helped a little. It's not clear what causes it when it messes up and when it doesn't. Just frustrating. It's probably user error because I'm so new at Photoshop. Thanks for your input. I really appreciate it.

Keyboard & Mousepad Just Stops Working

About 4 days ago, my Pbook G4 would just suddenly stop letting me type or move the mouse. What ever was going on in the screen continues to work normally, but the keyboard doesn't. The only button still functional is the power button. I tried plugging in an external keyboard and mouse, but that was useless. Can anyone help?
Also, the only most recent thing I had done was install the Safari update that my software update asked me too.
Thanks for any help!

I had same problem and had keyboard replaced at Apple authorized repair center. Keyboard still stops working on occasion. Problem started earlier this year. I believe it is software related.

Well last night after I had got off the phone it had froze up (never happened before) and then it it went blank. I would call it from my house phone and it would ring and vibrate but nothing showed up on the screen. I just need help please :(

Try doing a hard reset, Hold the "Home & Power Buttons" down at same time, until you see the Apple Icon appear. Then let go of the buttons.

ML upgrade process freezes, help please!!

Hey, I have a MBP 13" mid 2012, and I was just trying to upgrade from Lion to Mountain Lion. Just about 12min to finish my Mac completely froze. I had to force a shutdown while pressing the power button. Now I turned it on and the Installer popped up and now it trying to install it again, I hope it doesn't freeze again. I'm realy scared (hopefully I have a back up).

Hi Gulliver (and thanks for your welcome),
I'm pretty sure that our system requirements are OK. We have an iMac G4 with superdrive, 512mb RAM, 80GB hard drive, no 3rd party cards, currently running 10.2.8.
I do have the full DVD - bought from an Apple shop, not coming with any other hardware.
I had actually already seen your 'Decision Tree' from another post. I note that you recommend an Archive and Install from 10.2.x, but at the moment we can't get past the destination drive part to choose that option!
I think the next thing we need to try from your procedure is to run DiskWarrior or TechTool Pro 4. Which means I'll have to reset internet settings so that I can get them! (Checking from work it seems your TechTool link does not work - searching on Micromat, I'm not sure which version we would need to use - possibly Classic??) Are these available for free? I'm a bit loath to throw money at the problem just yet... especially when it's not certain that it will solve the problem anyway. If we do this, you state - "Make sure you use the latest version, older versions might not be compatible with Tiger!" - do you mean even if they are not compatible with our current operating system? Sorry for all the questions!
No doubt I'll be posting again after I've tried that!
Thanks again.

Can not install windows 7 pro using boot camp as mouse and keyboard will not work Help please

I have a new iMac and trying to install Windows 7 Pro using boot camp. I have reached the stage of starting to load windows from the DVD then discovered the mouse and the keyboards not working so I could not interact with windows installation.

Open, if not so already, the Windows formatter. Identify the BC Windows partition. It will be the one listed with the proper size you created and/or will be labeled as a C: drive. Be careful you select the right one or you may be corrupting the entire drive.
Format the partition as NTFS.

Whatsapp and instagram won't open - they just crash help please!

hi, i have an iphone 4s. yesterday my instagram app wouldn't open, it would just crash. then today the same thing is happening to whatsapp!! what does this mean and how can i overcome this??? thank you!!!

This is not a standard problem with Safari/Firefox on the Mac that I can see. For example, when I go to http://www.boursedata.com.au/solutions/default.asp it loads the page normally (note: I have a historical association to that company... I have used it because I know it uses asp!).
What does it do for you?

New Keyboard + Last Gen iMac Help Please

Hello,
I'm using the most recent generation (right before the release of the aluminum ones) iMac Core 2 Duo 2.16 20" and I have a very minor problem:
I ordered the new wired keyboard - the brushed aluminum one... wow it's awesome - super thin, nice keystrokes, beautiful sleek design.
I plugged it in, did the software update, reset my system - all as expected.
So now, my F1-2 keys work great for the display dimming, keys F7-9 work fine for the media, and F10-12 work perfectly for volume control.
The 2 things that did not carry over perfectly were the Expose functions of F3 and F4.
F3 and F4 were not re-programed with the update to include "all windows" for F3 and Dashboard for F4
Anyone else have this problem, or any other thoughts other then trying to reinstall the keyboard software update?
I can assign things using Expose in settings, but if I assign to F3&F4 I have to press the Fn key and F3 or F4 to get them to work.
Thanks for the help

Just a followup to other comments. I have always liked the MacBook Pro keys so I purchased the new keyboard to go with my G5 Mac Pro.
I concur. All special Fn Keys work normally with the Fn Key Option (in Keyboard Prefs) turned off -- Except F3 and F4 (Expose and Dashboard).
These 2 Keys work kind of the reverse of what is expected. If Expose and Dashboard are assigned to F3 and F4 in the Dashboard/Expose Prefs the F3 & F4 Keys will work if the Fn key is also pressed (kind of stupid)
However Expose and Dashboard can be assigned to other Fn Keys (F13, F14) and they will work normally (no Fn Key required)
I think the keyboards (mine and others) are fine. This seems to be a software issue. Apple rushed the software update out and it needs some tweaking. Lets hope it wont be to long

Dell inspiron 5030 laptop keyboard issue ...HELP PLEASE

Here is the instructions for removing the keyboard:
http://support.dell.com/support/edocs/systems/insm5030/en/sm/keyboard.htm
I would suggest removing and cleaning it gently. If that does not work, you may need to replace the keyboard. I was not able to find a replacement keyboard, unfortunately, or I'd post it. Further research is needed, or bring to Geek Squad for repair.
