If those solutions don't work your iPhone 4s has developed a hardware problem. The permanent solution is to get it replaced. I have not heard of Apple replacing long out of warranty iPhones.
You can search the internet for heating and freezing solutions that might work (at least for a while).

HT4650 My keyboard has stopped working after an update of Flash Player. Help! What can I do?

Why has my keyboard stopped working after Flash Player update?

Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
Do things work in Safe Mode?

Acrobat XI Stopped working after CC Updates

RANT: It's happened 3 times now, and I'm getting fed up of the Adobe support - very disappointing. I don't think they know how to handle issues, and sometimes wonder if they even know the basic difference between hold and disconnect. Numerous times I have contacted them, after chatting with them for a few minutes, they say that they have to trasnfer me to the technical support, and then I get disconnected. Then the next guy has to start all over again with the same questions. Horrible.
Ok, rant is over (for now), hopefully this forum is more helpful.
ISSUE: last few (3) times I have noticed that when I update my Creatve Cloud panel, my Acrobat stops working. I'm not entirely sure if this is related to the CC panel update, but that's what it seems to me right now. So, after numerous chats with the Adobe chats, and my own office IT, I (myself) figured out that the issue could've been because I see 2 Adobe Acrobats installed on my system. The screen cap below shows what I mean.
Last 2 times I uninstalled both, and reinstalled the Acrobat from the CC panel again, and it worked. But this time it just dind't. And I've been totally unable to solve the issue with my IT and Adobe's support so far.
So, what happens is that when I launch Acrobat, it asks for licensing information again, or it says it would launch as a trail version... Come on, I'm already paying for the whole package.
Desparely hoping that the Adobe Forum Community is more capable for such support...

I've had numerous chats with Adobe support agents, and with my own IT, and haven't had luck yet. It's been a terrible experience stuck between the two IT support departments as a user I'm the one who's suffering and not these support guys...
The issue here is that my Acrobat is not working as it can't find the internet connection, even though all the other Adobe products in the Creative Cloud work fine.
We use Proxy scrypts in my office, and even though all Adobe links provided to me by Adobe, have been white-listed by my IT, Acrobat still hasn't worked.
I've tried it all, installing, uninstalling, Adobe clean-ups, registery edits, preferential boots etc etc. Still no solution.
Is there no way to manually enter a serial number to get it working???? What if someone loses internet connection, does it mean the Adobe Creative Cloud products are useless in that scenario, even though one has paid for months...
Damn, I'm angry with myself for pushing for Adobe CC upgrade. Sigh.

Satellite A105 Shift Keys stop working after BIOS update

I have a stack of laptop boards from the A105 series (Intel chipset) that I received with bad BIOS's. Two worked, and I updated the BIOS's on them to fix CPU compatibility issues. After that, the shift keys stopped working, and pressing Shift-A causes the power light to dim. Reverting to ANY previous version BIOS, whether through the Windows program, CD, or Crisis Recovery floppy (magic key is "F", not "B", "Esc", or "U"), does not fix the keyboard problem.
To make things more confusing, I did notice that the one single BIOS that seems to actually correct the problem is version 1.50, which I haven't seen available for any Tecra A7 or Satellite A100/A105, except a couple A100's, but the BIOS file is much too small and can't be loaded.
Does anyone have any idea why these Intel-based boards are doing this? Or does anyone know where I can get a usable version 1.50 BIOS?
For the sake of this post, please consider my skill level to be high. (In other words, I would be thankful for people trying to help with "Replace the keyboard", but I have about a dozen keyboards, all of which I have tried, and all of which work on other laptops. Additionally, if you have just a theoretical solution, I'm definitely open to hearing it. Also, if a Toshiba tech would like to reply, I would very much appreciate it!)

Hi, thank you for your help.
Some motherboards were not in chassis when I got them. Is there a place the PSAAxx model number would be written on the boards?
Four PSAA8U (Two A105-S4334 and Two A105-S4014) - Intel Chipset, fingerprint reader. Tried BIOS Versions 1.40, 1.70, 2.00, 5.10, 5.60, 5.90, and 6.00. Shift keys do not work on either one.
Two PSAA2U (A105-S2091 and A105-S2031) - ATi Chipset. BIOS versions 1.50, 1.80, and 2.30. Keyboard works.
Another PSAA8U (A105-S4184) - Intel Chipset, no fingerprint reader. BIOS version 6.00. Keyboard works.
I noticed that so far all of the models with fingerprint readers have the problem. All of the ATi Chipset boards are working fine, but they have significant processor limits. I am in the middle of updating the BIOS in another Intel one using a Crisis Rescue Disc, so after that finishes I will try disconnecting the fingerprint reader to see if it has an effect.
I don't think the keyboard controller is faulty, because these boards all failed on the same day. I have tried updating the BIOS using WinPhlash, Phlash16 in DOS, the install CD, and a Crisis Recovery Disk. I set the defaults in the BIOS almost every time, and I also have tried holding the power button for 60 seconds with the power cord unplugged and the battery removed (as some people have suggested.)
The shift keys don't work in DOS, Linux, Windows, or even in the BIOS. I test it in the BIOS by using Tab to cycle through the fields in time of day, then Shift-Tab to cycle backwards. This works with a USB keyboard, and it also works on the ATi chipset models and the Intel chipset models that are still working.
Thank you for your reply. (-:

Command line option "-save-to-folder" stopped working after last update: Any workaround?

Running FF on Linux, I was using the -save-to-folder option at CLI to write a copy of the webpage to file with JS content rendered. Worked great until the recent update (to v.27.0.1).
Typical format was: firefox url -save-to-folder filename
When things break, the fixes sometimes happen quickly, sometimes not. In the meantime, anyone have a workaround?

[http://ubuntuforums.org/showthread.php?t=2210953&p=12955762#post12955762]?
It will depend if your Linux build was compiled by a third party. Typically if a function like that stops working, uninstalling might be a good option, but maybe not in this case.
The full list are [https://developer.mozilla.org/en-US/docs/Mozilla/Command_Line_Options] is this one custom perhaps?
There is an add on [https://addons.mozilla.org/en-US/firefox/addon/save-file-to/ Save file to] that adds a dialogue, but you may want to stick to linux. There is a customize shortcuts [https://addons.mozilla.org/en-US/firefox/addon/customizable-shortcuts/ add on]

Win 7 Drag and Drop stopped working after iTunes update

I really hope that this is the right sub-forum for this.
Here goes:
A few days ago I finally upgraded to 9.1.1.12 and today I was in for a nasty surprise: I can't move MP3s from windows explorer into the iTunes window any more.
I often create playlists and then drag files I get from a few bands I follow directly into those playlists. This is an easy and painless process. My FTP client downloads the files into a prearranged folder whenever they get a new song up, and I then open said folder and drag and drop the file into iTunes.
I just got a new song to listen to today, wanted to drag it in an... Nothing. Just the black, crossed-through circle of "No".
It worked last week. It worked the week before. It worked the years before.
I got Win7 64 in April. It worked on it since then.
It stopped working today.
And no, I won't let iTunes consolidate or organize my media. It only organizes files bought via the iTunes store, nothing I rip from CDs or obtain otherwise, as those files have to be playable by two other players as well. But, again: Until this night it worked without a problem. And after the new update... Stopped.
Is there a new option I'm missing?

I was able to fix it.
I simply stopped running iTunes in Admin mode. For some reason, running it in administrator mode makes it behave "worse" than not doing so.
When I ran it as a normal program, I was able to drag files into it correctly again.
Which is weird, as the last version was also running in admin mode, but worked perfectly.

Bluetooth Mouse stops working after software updates

Hello,
I've been using a Bluetooth mouse with my X220 Tablet for several months now. After fiddling with device manager to ensure that the Thinkpad Bluetooth device does not have the "Allow the computer to turn off this device to save power" setting set, things were working perfectly.
However, after running through some windows & Lenovo updates, the mouse now seems to work for a while, but after any idle time, the mouse stops working. Turning the mouse off & back on seems to cause it to reconnect, and it works until the next time it goes idle for 2 minutes.
I've gone through device manager, and made sure both the Bluetooth & USB Root devices are set not to power down (per http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/Bluetooth-mouse-stops-working-from-time-to-tim... ), but still no luck.
The software updates applied from the Lenovo System Update tool were:
ThinkPad Power Management Driver: 1.67.04.05
ThinkPad Power Manager: 6.64.4
Lenovo Solution Center: 2.4.002
Intel G1/G2 Display Driver: 9.17.10.3347
Also, some windows updates which don't seem related (mostly security), but I can lookup the list of KB numbers if helpful.
Are there any known issues with the power manager updates that might affect this? If so, what's the best way to revert to the last working version?
Thanks!

Try doing a PRAM reset and see if that helps, also put in new batteries as that may make a difference.
