Keyboard works intermittently after deep sleep

Hi,
when my Macbook Pro comes back from deep sleep (i.e. if battery went out during the night, with the mac in sleep), the keyboard first works just long enough for me to log in, then starts working intermittently, like for 15seconds periods every 5 minutes or so.
The only solution is to reboot my computer.
10.5.1 didn't solve the problem.
That problem is a definite showstopper. It renders my computer unusable.

I turned off deep sleep 2 months ago and still had the missing first key stroke problem.
then upgraded to 10.5 then had the total keyboard freeze. seemed to happen more on battery power. repaired disk permission and the freeze has stopped but still random missing keystrokes it seems to happen most in highlighted dialog boxes. turning off bluetooth helped with erratic track pad when waking from sleep

MacBook Keyboard Works Intermittently After Upgrade?

Suddenly experiencing occasional keyboard 'outages' on my MacBook. Seems to occur after waking from sleep. The keyboard will work then stop for a minute then work again. Trackpad continues to work.
Anyone else seen this? No 3rd party keyboard or mouse software installed.

Had the same problem. Fixed! Here are the steps:
1) shutdown system
2) boot with while holding down shift key (safe mode)
3) launch Finder | Utilities | Disk Utility
4) select Macintosh HD (your system hardrive)
5) click on "Repair Disk Permissions" (this will take a while)
6) restart system
While waiting upon 5, I notice that my keyboard was working fine in safe mode. Not sure is steps 1,2,6 are needed; it could be that steps 3,4,5 are all that you need.
Mileage may vary. Please post your results. Many thanks to the Apple technician (for case# 86941514) who solved my problem. I was so not looking forward to sending in my macbook, like someone else with this problem has done.

SSD and corrupted menu after deep sleep

SSD and corrupted menu after deep sleep
Hi, I have a MacBook Pro mid 2012 13 inches (9,2).
I run it with 16GB of ram and OSX 10.8.4
I replaced the internal HD with an Adata SX-910 model (512GB) SSD.
(http://us.adata-group.com/index.php?...cid=3&piid=183)
It runs really fast! Boot time is 10 seconds! :-)
However I have a major problem! When I MacBook Pro will end the battery energy and will go below 3 percent, the Mac will go to sleep itself. When I will start back the Mac, with the power connected, every time I will see the desktop colors corrupted and the menu of Apple Safari, Apple Mail and few others gone! Only solution is to re-install Mac OSX!
I took the Mac to an Apple center and Apple did NOT find any problem with the Mac itself. I have returned the Adata to the vendor and got a new one (with latest firmware).... However I have discovered that the problem is happening again! :-(
I have tried to use Insomnia smartspleep tool, but does not work as expected.I think that only solution is to re-charge the battery before it goes below 3 percent.....
please note: using the trim enabler tool did NOT solved the issue:-(
Any suggestion?
Maybe it is indeed an issue related only to Adata SSD? I am confused and frustrated.

Clinton,
Apple hibernation has three modes. By default, on laptops it suspends the system and make a copy of RAM to disk for a completely safe hibernate. When you have 8 Gigabytes of RAM it takes twenty or thirty seconds to write that RAM image. I suspend/resume often during my day and don’t want to wait. This has worked really well for me.
You can change the Mac’s hibernate behavior using pmset; here’s the reference for it:
http://developer.apple.com/documentation/Darwin/Reference/ManPages/man1/pmset.1. html
“sudo pmset -a hibernatemode 0″ = suspend to RAM only (default on desktops)
“sudo pmset -a hibernatemode 1″ = suspend to disk only
“sudo pmset -a hibernatemode 3″ = suspend to disk + RAM (default on laptops)
How can I set my MacBook Pro to go into deep sleep, I guess it is mode 0, BEFORE the 3 minutes remaing time? I think to be safe, it should go to deep sleep automatically when it is around 15 percent batter level.....

IPod gets stuck when it starts play mostly after deep sleep

Hi,
I have a problem with my 60G Video iPod:
Most of the times it gets stuck completely when I start use it after deep sleep (it hasn't been used for night etc.).
The problem is very consistent:
1. I turn it on.
2. Start playing some song.
3. See the 'normal' play screen (song timer is 0:0)
4. Hear spinning and clicks of hard drive and ....
5. It just freezes: doesn't response to any key (including Hold)
Only Reset helps now and when I generally get Folder icon with exclamation point and
it needs at least another reset to be able use it.
I updated iPod to the last version (1.1) - doesn't help.
It passed through Restore - same results: Every second turning on it gets stuck.
Does anybody have/know about similar behavior?
I think I have to ask Yeda for help?
Any ideas?
Thanks

Macbook Pro Retina Mountain lion freezes after deep sleep

Hello All,
I am having a strange problem with my MacBook Pro Retina, Mid 2012 (Mountain Lion 10.8.3). Since about January time It keeps crashing after I put it into a deep sleep. After closing the lid - waiting for 1 hour or so - then reopening the lid, i get presented with the normal Apple login screen (breifly) and then it crashes and i get a grey screen saying my mac has had an issue and it needs to restart.
When i log back on i get an error message that I can send onto Apple and then my Mac carries on as normal. Very weird.
I have searched these forums, been into the Apple store, spoken to Apple done hardware diagnostics, reinstalled the OS (worked breifly then stopped working again) - so i assume its one of the programs or bits of hardware that i use (which i have tried to isolate/remove)- but i am still strugling to solve these issues.
It would be great if someone could give me some advice around:
1. Where I can find these log files/error messages, etc.
2. Understanding what it is causing this issue.
Thanks in advance.

The solution is to dump the 100€ mini-display port DVI-D adapter that apple sells and buy a mini-Display to Display-Port cable for 6€. No crashes, no annoying interruption of the display (which I had several times the day for 2 or 3 seconds). There are very short interruptions now, but it is much better than with the apple adapter. The apple adapter needs a USB port, which is not necessary with the simple cable.
As for the monitor: Burn In, otherwise great. The burn in can be erased via monitor menu but should not be there in the first place.
Hope this helps.

Charging Problem after Deep Sleep

Hey
All works fine but, when i wake up my MacBook from the Deep Sleep Mode, it seems, that my MacBook doesn´t know, if the MacSafe is plugged in or not.
Normally, when you plug in the MacSafe, in the menu bar the batterie status goes to "charging". But after the Deep Sleep Mode, my MacBooks doesn´t know, that i turn off the MacSafe. All the time, it shows the status, "charged" in the menu bar.
So the Problem is, that my MacBook doesn´t show the right charging status in the menu bar. So i
don´t know, how the batterie status is.
That´s very strange.
Somebody who can help me?

if you haven't already try listing your problem in the Powerbook forum. Sounds like its most likely an issue with the PB.
Also, have you tried putting the ipod in different settings? As in;
Enable Disk Mode
->itunes open
->itunes closed
Open itunes when this ipod is connected
->itunes open
->itunes closed
and then combining the two...

Songs seem lost after deep sleep

After I wake my iPod Photo from deep sleep, none of the songs show in the menus. The only way to fix this is connecting it to my iBook. This is ofcourse very irritating, because I don't always have my iBook with me. I have updated the iPod recently but it doesn't help. I haven't always had this problem.
Does someone recognise this and knows what to do?

I had this same problem and finally went back and reinstalled version of iPod updater 2005-03-23. I purchased by photo ipod last February and it worked fine until I updated with 2005-6-6-26 version, and then it started the problem with the music disappearing and needing to hook it back to my Mac so the music would show up. It does appear to be corrupting the directory, because the music is still on the iPod, but it does not display as being there on any of the munus.
I am currently running version 1.2.1 of the iPod updates, and it does lock up from time to time, but I can easily do a manual reset, and the tunes are still there.
I have not run the updates because each time it causes the same problem to come back.

TS3048 My mouse still works intermittently after following the above steps

My 9 month old wireless mouse now works intermittently. I hooked up my old trackball. I followed the steps onthe troubleshooting page -- basicallly changed the batteries and make sure the sensor window was clear. The desk surface is a little rough but it worked fine for 9 months. Any suggestions?

Hello:
Try resetting the PRAM and SMC.
If that does not work, contact Apple for a warranty replacement (yours is still in warranty after 9 months).

Hp netbbook 210-1010 keyboard works intermittently

I've had my hp mini laptop 210-1010 nr for approximately 15 months, and the keyboard has started doing something odd. The g, h, comma and backspace keys only work intermittently. This is not a sticking problem, as the keys pop up normalyl. Sometimes the keys work, and sometimes they don't. Is this a keyboard driver problem, or a keyboard issue? Thanks in advance!

I read somewhere (I have the same problem -- with keys GH" and backspace) that it is caused by a heat issue -- but I don't buy that because the behavior doesn't seem to match up with hot/cold, cold boot/long session, etc.
I've installed the latest version of the keyboard driver (at least as of several months ago), and am more than a bit upset that the problem has not improved. But from everything I'm reading, it's a hardware problem that is not going to go away.
So whenever possible, I use an external bluetooth keyboard with my 210HD.
Otherwise, I love this system -- which makes this flaw all the more maddening.

Bonjour Stops Working Intermittently After 7.3.1 Firmware Update

After updating the firmware on my Airport Extreme to 7.3.1, Bonjour seems to stop working intermittently. This affects both the 802.11N (MacBook, white Intel iMac, and aluminum Intel iMac) and 802.11G (MacBook) clients on my WLAN. I also connect to the AP with an iPod touch and a Wii. All the Macs are running 10.5.2.
Cycling the power on the router seems to fix the problem for a while.
Here's a snippet that might be related from my system log:
Apr 15 18:56:25 Jiminy mDNSResponder[16]: SetupAddr invalid sa_family 0
Apr 15 18:56:26: --- last message repeated 1 time ---
The only other network-related change that I have made recently is playing WoW.
Anyone have any ideas?

I have the same problem, btw. My AEBS 7.3.1 routinely loses all Bonjour support. Restarting the base station or power-cycling are the only fixes. I don't think the issue is on the Leopard side, but I'll reboot my laptop the next time it happens just to be sure.
Bonjour for Windows creates a JetDirect-style printer connection if I recall correctly. So after using it to discover and setup a new printer, it wouldn't really matter anymore if it suddenly disappeared. I'd have to double-check this to be sure, though.
On that note, I would recommend using JetDirect-style connections on your Mac, too, since bonjour connections are notoriously flaky for large print jobs like printing 8x10 photos.

I have iMac 27. After Mountain Lion install, my trackpad freezes partially after deep sleep and need to restart to get it working again. anyone with same issue?

I have an iMac 27 and installed Mountain Lion last week. Since then, after a deep overnight sleep, certain of my trackpad functions are frozen after i wake the Mac. i need to restart the computer in order to get the trackpad fully functional. Anyone with same issue or ideas?

I'm having the exact same issue with Mountain Lion on my 2008 17" MacBook Pro. I've just tried the SMC reset, so we'll see how that does. The problem was intermittent, occuring not after every wake--from-sleep, but every few.
Interestingly, my 2007 17" MacBook Pro is also running Mountain Lion (the oldest MacBook Pro than can!), and hasn't had this problem at all.

Push email (MS exchange) works intermittently after upgrade to ios 5.1 and ios 5.1.1

I have an iphone 4 with my office email (MS exchange) account configured. Other accounts are Gmail & iCloud.
Office email is configured as Push, Gmail as Fetch and iCloud as Push.
Till ios 5.0.x everything was fine. Office emails were getting pushed and there were no issues.
However after upgrading/restore to ios 5.1 & then 5.1.1 push email mostly does not work.
Few observations :
1. Push email works fine when I am at home on wi-fi.
2. When I leave home for work (therefore on 3G), mails stop getting pushed. Sometimes they get pushed for a period of 1 to 2 hours. Then they stop
3. Manually fetching office mails also does not work
4. Strangle accessing the office webmail site in Safari https://mail.xxxxx.com does NOT work. While i can load other sites in safari, the mail site does not load.
5. In office sometimes in the lift phone switches from 3G to Edge or no signal and then when out of the lift, suddenly mails get pushed, but then stop after some time.
6. Moment I get onto wi-fi, push emails start working
7. There is no issue with accessing gmail.
8. Other push notifications work (gmail app, facebook notifications etc)
9. There have been no changes to our MS exchange server
10. I have tried the usual stuff of resetting network settings, rebooting the phone, killing the mail app, going to airplane mode, deleting the mail a/c and recreating etc etc. But no luck.
Apart from upgrading/restoring to 5.1 and then 5.1.1, there have been no changes. The upgrades were done OTA, restore from 5.1.1.
However both times I have not set the phone as new and have restored backups.
Is anybody facing a similar issue ?
Any suggestions ?

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Has any of this been tried?

Losing Songs after Deep Sleep - still happening

I thought my issue with the Song Library disappearing had magically fixed itself, but it has returned. Three times in the past week the library has been empty when turning on my 20GB iPod. I don't think it had even been 36 hours since the last time I used it.
The reset option does not work in this instance for me. Everything shows backup as soon as I connect via the USB cable.
The previous posts on this issue have all been closed. Is this still happening for other users or is there a fix? I am running version 1.2.1.
My next thing to try is a total reformat to see if that helps.
Thanks.
