AT300 tablet wont boot after operating system update

Hi
I ran an automatic update on my ICS AT300 tablet and now it will not boot. I have ran a factor reset but the results are still the same.
When I power the device on it runs the TOSHIBA Leading Innovation screen and then goes to the loading screen but does not go any further.
Please help?

Did you try to boot the tablet in safe mode to check if this is possible?
To reboot into safe mode, press and hold the power button until the power options menu appears.
Then press and hold the Power Off option until youll be asked if you want to reboot your Android device into safe mode. Tap the OK button.
Then the Safe Mode should in the left bottom corner of the screen.
In safe mode, you have got an access to the apps that came with your device.
Apps youve installed will be disabled.
If your issue does not appear in Safe Mode, the problem occurs to a third-party app youve installed.
While apps are disabled, you can uninstall them normally.
Open the Settings screen -> Apps -> locate the app you want to uninstall and tap the Uninstall button. if youve installed any apps recently, you should probably try uninstalling those apps first.
If youre experiencing major problems with your device, you may want to skip all the troubleshooting and restore your device to its factory default settings. Open the Settings screen -> Backup & reset -> click Factory data reset, and follow the instructions on your screen.
_By the way._
To exit safe mode, pess the power button, select Power Off and restart your device in normal mode.

Photos missing from iPhoto after operating system update

I recently updated my Macbook pro operating system to OS X version 10.10.1 and iPhoto to version 9.6 (910.29). After the updates, most of my albums in iPhoto are empty and in the photos folder, all photos pre-dating 2010 are missing. How do I recover these photos?

Obvious: restore from the back up you made prior to upgrading.
If that's not possible:
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

Imac wont boot after this last update

I downloaded an update (automatically through software update). After it installed it told me to wait for computer to restart and then hold power button until the long tone, then it should be done. I did that with no problem.
Ever since then though it wont boot regularly. It wither sits at grey screen forever OR gives me the prohibit sign. The only way to get it to work it to hold that power button until the long tone again.
Any idea whats wrong and how i fix it??
Thanks in advance for any help.

The long tone is an indication that a firmware update is installing. Do you get a progress bar at the bottom of you screen after letting the power button go?
Have you reset the PRAM? (cmdalt+PR when you restart the machine)
Also repair permissions when the machine is up and running.

My Macbook Pro wont restart after a system update

I bought a macbook pro in November 2012. I did a the most recent mountion lion system update. It will only shutdown by holding the button. When booted, after entering my password for the user, the mac will run but the screen is black. The commands or trackpad do not respond.
What do I do?

First you should try to back up anything in your hard drive that is really essential, like files you can't afford to lose. Then I'd try to boot into recovery mode, which you do by restarting and holding down command R (I think. I've gone to bed so I'm doing this from my phone. But you can google recovery mode. ) once you have booted up in recovery mode, use disc utility (it will be very apparent where that is) and repair your hard drive and permissions, and then try to start up normally. The fact that the computer did start up in safe mode is pretty good evidence that there is a problem with some third-party software that you have previously installed, so this may require a trial and error process to find out what that software is that is causing the problem.

HP 8740w WH279UA wont boot after Windows 7 Updates

Hi!
Thank you all for reading my case. I'm the happy owner of a HP 8740w, I have 20GB of RAM and 500GB hard drive. My litle monster has been working perfectly for the last year and a half.
My problem began last night while I was doing a fresh Windows 7 Pro Installation, I did this after installing Windows 8.1 on the laptop and I was not happy with the overall system performace. these are the steps I run before the computer stopped working:
1. Boot from Windows 7 Pro DVD
2. Delete/Create/Format hard drive
3. Computer Boot Ok
4. Installed Wifi Driver Ok
5. Downloaded all System Drivers from HP website
6. Installed all System Drivers
7. Reboot computer it showed 107 windows Updates to be applied
8. Computer Rebooted 2 times while configuring updates
9. Computer Failed to Boot
Now every time I boot the computer the Caps Lock and Num Lock leds Blinks 3 times, according to HP Web Site the 3 times blinking leds indicates Memory Chip failure, these are the steps i tried to troubleshoot the memory error:
1. Boot the computer with the combination of the 4 memory so-dimms, failed
2. Boot the computer without memory, failed
3. Boot the computer without memory, and without hard drive, failed
4. Boot the computer without memory, hard drive, and motherboard battery, failed.
I reallt don't understand how can this had happend to my laptop. Warranty ranned out on 2013 so i'm not elegible to request a replacement. any ideas?

Battery wont charge after recent system update

My bluetooth device errored and I had to download the drivers again so thought I'd update my system at the same time with some of the latest Lenovo updates - Terrible mistake!
Lenov have changed their power management so that it "may not support batteries that are not genuine Lenovo-made or authorised" . What they mean is we're gonna screw you over!
My compatible extended life battery that I've happily used for over 6 months now does not now charge and I use my laptop for business and often on the go so battery is imperative.
My laptop is out of Lenovo warranty so I am utterly disgusted they are trying to force me to pay nearly £200 (which I dont have) for their own batteries when it should be totally my choice. It's monopolisation surely! It's not that I have bought a non compatible battery that doesn't work, its the change in software through upgrade that they have forced this upon me and I am seething to say the least.
Is it possible to go back a version of power manangement (I presume it's power management software) so that i can live happily ever after?
This is an urgent problem for me so please, anyone?
Richard

The warning in the power manager have said so for ages, and doesn't mean that your charger won't charge third-party batteries. It just means that Lenovo doesn't take responsibility for third-party batteries, and can't guarantee that charging will work with third-party batteries.
If it suddenly doesn't charge at all, there's probably something else wrong - it's not the power manager update.

any body an idea what i can do to fix it?

hi - i think you should not use 'xhost +' - it's not secure and you shouldn't need it....
in your .bashrc or .cshrc or whatever, you should have setenv DISPLAY .0 or the equivalent export...
then ssh -Y hostname should be all you need... no xhost, and not setting DISPLAY every time...
could you enter the following command from a terminal window and post back the results?
grep X11 /etc/ssh*_config

Wanted to use Icloud to back up pictures and Itunes - it is running os 10.6.4. I have an original IPAD, nothing syncs without connecting. Do I need to purchase operating system updates? Wasn't sure what 10.6 Leopard is?

Snow Leopard, Mac OS X 10.6, is not iCloud compatible. You need to upgrade to Lion, Mac OS X 10.7, via a download from the app store...$29 (US), provided you had at least 10.6.6. You can upgrade to 10.6.8 for free as part of the software updated function, then go to the app store and purchase the Lion download.
When you do that, before installing Lion, make a copy of the Lion Installer from the Applications folder where it downloads to some other location, such as your Documents folder, so you have a backup copy.
For Lion you must have at least an Intel Core 2 Duo, i3, i5, i7, or Xenon processor, 2 GB memory though 4 GB is better and 7 GB free space on the hard drive.
As part of 10.7.2 you end up with the iCloud connection.

My 3gs wont restore after ios 5 update. I have tried firmware restore and restore from backup, neither works. All I get is "iphone restore failed because backup session failed" Any ideas on how to make a successful restore with this ios 5 update?

I was having the same problem, I backed up my phone and then updated to iOS 5 and then it kept telling me it could not restore from my backup as it had failed. After reading a bunch of forums and posts and trying everything, I did manage to get it to work. I had tried the Time zone, creating a new computer user account, disabling anti-virus, etc.
It took a combination of things, one of which was disabling the anti-virus completely and copying the contents of the backup folder to my desktop and then deleting everything in the backup folder. Then I rebooted the PC, entirely disabled the anti-virus, copied the one backup I wanted to restore from the desktop to the backup folder and then trying to restore. Low and behold the phone said restoring from backup and I am back in business, so when in doubt, trying combining some of the fixes together.
