I can attach screen shots if you need it, currenlty when it is in ideal - im getting reading of 58 c to 60 c
is this normal?? please help me out.
Thanks alot in Advance for your help.

As a meego developer I know where to get the public packages, but I was expecting that lenovo added some stuff for better support on that shipped version...
I any users tests a meego lenovo system , feel free to review it here ....
Anyway this is a good start for us that vendors try to promote other system, i am not sure the whole world is happy with a single OS , at least I am not and I am forced to buy it even If I have no plan to use it ... any tracks to get a refund for that as the microsoft licence suggests ?
But here, let's keep focusing on leveno GNU/Linux projects :-) any involvement into upcoming tizen ?

I have iphone 4 with iOS4.0, how to revert back version of facebook app version because i am not able to use facebook 5.0 in my iphone?

That depends. If the phone was unlocked by the carrier, then it should be fine.
If your phone was unlocked by unauthorized means, then yes, it will be locked again.

URGENT: u410 incorrect bios version provided at Lenovo website

The u410 Ultrabook currently sold by Lenovo is being shipped with Bios version 65CN15WW.
Online, Lenovo provides an older version 65CN13WW.
Bios version 65CN15WW is corrupt, network problems with the wireless adapter have been reported. Also, Windows clean install on models with this bios are not possible, especially if the original partitioning table has been changed and the RAID has been deleted.
If one disables UEFI in bios, the bios can no longer be accessed.
Flashing the Bios witn version 65CN13WW is not possible. Because 65CN13WW is an older version of the bios, all attempts to flash the bios result in a message "invalid bios" and the flash is not applied.
THIS NEEDS TO BE FIXED ASAP. The different forums (English, Deutsch, Espanol) are littered with messages where users are not able to install Windows 7 and are not able to upgrade to Windows 8 because of this corrupt bios.

just to clear up one of the points made in this thread; it is not uncommon, (other manufacturers included), for a system to be delivered with a different bios version to that which is available for download.
This has been stated on previous occasions by Lenovo employees; an example.

sometimes we introduce newer versions into manufacturing to support an update to something like the chipset or later version of processor introduced during product life. Since the particular change doesn't apply (doesn't benefit) the field population, it may not be immediately placed on the support site for download. Development may wait for a later iteration that includes updates that are relevant (fixes) and then release that as a cumulative update.

I accepted/installed an update for iMovie and it turns out that this version is not compatible with my graphics card. So now I can no longer open or use iMovie. Any ideas on how to get around this - how to revert to the previous version.

Look in your Applications folder. If your system behaved as expected, you should have an iMovie 9.0 folder in your Applications folder. Apple moved the old version there as even they suspected the new versions was a train wreck.

Qosmio X300-14Y- How can I find the old BIOS version 1.90?

Hi,
First of all; I am so sorry for my bad english knowledge..
Im from Turkey.
I use x300 14 y since one week. factory bios version for vista 32 bit 1.90. But I upgraded to 2.10.
How can I find old bios 1.90 setup file again. ? Please help.......

You are right. On Toshiba download page you will not be able to find older BIOS version.
When the new BIOS update is realised the old one will not be available for download.
If you need older version contact nearest authorized service provider.
They must have it. Be cool and talk with them. Maybe they can send it to you per mail.

How can I restore the latest BIOS version when it doesn't appear in "Software & Drivers" page ?

When delivered, my brand new Pavilion desktop model 500-282ef was equipped with BIOS version 8014.
On the EFI\HP\Bios partition, only the \Current directory contained another version of the BIOS, an older one, namely version 8013. The \Previous and \New directories were both empty.
Experimenting with my new BIOS, I've unadvertently downgraded my BIOS version 8014 to version 8013.
Now, as you've probably guessed, I would like to restore the latest version
The EFI partition doesn't contain any installer to restore my BIOS to its former up to date version.
Unfortunately, "the drivers and update" page on HP support site does not provide any installer either.
I would be so grateful if some of the nice people here would ask HP to point me to such (probably unreleased) updater which should obviously exist.
I have saved a copy of my second Pavilion desktop BIOS using safawin.exe in the hope I could use it to achieve a restore. But I've been unable to use it to restore the latest BIOS as the restore process also requires a signature file.
Thank you very much for your help!

Yes Dave, that's what I meant: during the "downgrade" from BIOS version 8013 to version 8014, no BIOS backup files were created and I couldn't found anything in any directory of the EFI partition.
In an attempt to solve the problem, I have put manually a copy of the BIOS (v 8014) from my second Pavilion Desktop (same model, same age) in the "\New" directory. That BIOS file was created with the safuwin.exe utility.
That has been a nice step forward: Now, from the Boot page, the Firmware Management offers me the update option ("You will update from 8013 to 8014, OK?") but when I try to so, I got a error message saying that a signature file should also be present along with the BIOS file to flash.
In the EFI\HP\BiosUpdate directory I do see some signature files like HpBiosUpdate.s14 and HpBiosUpdate32.s14 which could be the signature files I need, but I have no idea about how to use them (or maybe rename them?) to allow the procedure to complete successfully.
Concerning the warranty, do you suggest I should invoke it ? Could you please clarify ? Actually my PC has no other problem than this BIOS "downgrade".
I trust that HP has in store all the files I need, which have probably been used when configuring my PC in the factory. My problem is to have these files available in the "Software & Drivers" page on HP site...
Thank you very much for your help. I stay tuned

Of course my update was successful. I am able to see the 6.6 updates in other stuffs, as for example in /etc/redhat-release. Just the progress bar when Oracle Linux is bringing up is showing "Oracle Linux Server 6.4". My guess it is some kind of image, because it changes the color as the progress bar is going forward.
Actually, your update wasn't successful, or at least, it wasn't complete. The tool responsible for the boot loader screen is plymouth and the version comes from the /etc/system-release file. If the content of that file isn't "Oracle Linux Server release 6.6", then your update hasn't updated oraclelinux-release to the latest version.
However, if that file is correct, it means that plymouth hasn't updated the initrd properly during the upgrade. You can manually trigger a rebuild of the initrd by running:
# plymouth-set-default-theme text --rebuild-initrd
And it'll rebuild it for you. However, I've never seen a complete update (via yum update) that hasn't rebuilt this properly. Did you perhaps only do a security-related update using the yum-security plugin?

GTX 580 Twin Frozr II O/C - confused by bios version number, and how to flash

Hi, my first post here. But I've been reading a bit here. Still, I get confused by this whole vga bios thing, version numbers and how to flash... Ok, so here's my situation:
I have two PC's. Both with one MSI Twin Frozr II O/C GTX 580 card inside. It seems to me that both are working according to specifications, GPU-Z reports:
GPU clock 800 Mhz, Memory 1024 Mhz, Shader 1600 Mhz for the borth of them.
Now, one of them seems not to be totally stable (this is the newest I bought a few days ago). It locks up/crashes in some games. The other seems ok, I've been having that one for a while. Could this be a GPU core voltage problem? GPU-Z reports for the both of them:
VDDC 0.955 v
I've tried running MSI afterburner, changing core voltage to 1025, and in afterburner settings enable "Force constant voltage". Still, GPU-Z, which I keep running at the same time, still reports only 0.955. I thought this setting in Afterburner would change voltage to 1.025? This situation is for both the old one and the new one.
Now to the Bios "problem".
The newest card (the not so stable one) reports through GPU-Z: Bios Version 70.10.20.00.01
The oldest (stable) card: Bios Version 70.10.17.00.01
So... which one has the newest bios? Seems to me it is the newest card.
BUT - when running MSI Live Update 5 (newest version) it says for both the cards that they have the the newest bios version, and there's no need to upgrade??
SO - I go to the MSI webpage: http://no.msi.com/product/vga/N580GTX-Twin-Frozr-II-OC.html#?div=BIOS to download the newest bios manually, just in case.. But there it gets more confusing. The Bios version found there is :NV255MS.104(.zip).
And also, on that page I can not find how to use that file. Extracting it just gives me the file NV255MS.104 and no extension.
So, which bios is the newest one? 70.10.20.00.01 (the highest number, in the new card, but not stable in some games), 70.10.17.00.01 (in my old card, but seems stable in the games I've tried), or NV255.104 (which I don't know how to use).
I've flashed my main board bios many times over the years in various set ups, the bios on two different SSD disks and so on.. never had a problem with that, or finding out if I have the correct bios, how to do it and so on.
Maybe I'm stupid, but this MSI Twin Frozr II O/C GTX 580 bios thing confuses me a lot... So, how do I solve this situation?

I am also interested in the answer as I have 2 MSI N580GTX-M2D15D5/OC cards. I can find the latest BIOS file "NV801MS.KG4.zip" and know the version is "KG4". But how do you relate this to the current BIOS version Afterburner or GPU-Z provides? The version they each provide is "70.10.17.00.01" for both cards. The only other way to determine if they are up to date is to install and run MSI Live Update. MSI Live Update responds that they are up to date with no current version or online version information on the Live Update tab. At least the information on the Home tab states the same VGA BIOS version as GPU-Z and Afterburner. I can can only assume that the BIOS is updated by using MSI Live Update.
Also just for the additional information GPU-Z displays my VDDC as 1.039 briefly then 0.995 constantly when switching between cards. I actually have the cards set to 1.050 with Afterburner to be stable when running Crysis 2 DX11 updates.

How flash to old bios version (GT780)?

How can I flash my bios of the GT780 notebook to the previous version of the bios? Currently, the most recent version is installed: 1761_10E.zip
I might wonder why I would like to do this: I have some problems with my laptop (see other posts) and I'm not sure these problems were there when the old version was installed. I would like to find out whether the old version would solve the issues.

Quote from: Svet on 05-January-12, 02:03:02
and what was your old version?
I don't know :( :(
I bit of a long story: my brand new laptop had a defective USB port. MSI flashed the bios to the most recent version and on return I noticed the fan issue (the issue I PM-ed you about). Didn't notice this before, but I'm not 100% sure about this. So I would like to try to flash it to an older bios version if possible. MSI tried to repair the fan issue, but they didn't succeed. All in all: bought this laptop after summer and up to now not been able to use it because it has been longer for repair at MSI than on my table...

How to revert to older version of iTunes

I'm always apprehensive of updating iTunes to newer versions.
Just bought an iPhone 5 64GB and I'd like to sync it with music.
My older phone (32 GB 3GS) had complications when I first bought it, so I'd chosen never to update IT or my iTunes since.
The 3GS is still running on an older version (3.1.3 [7E18]) and it's been amazing through my 3 years of use.
The version of iTunes I'm running is 10.3.1 from back in 2011 (I believe) and I'm quite happy with it.
My iPods AND iPhone have given me no problems these past few years.
In order to sync my new phone, I'm expecting that iTunes will require the update.
So... Is there a way to SAVE my current version of iTunes (10.3.1) in case the current one is not to my liking?
I was hoping to save a copy of it to a USB key.
I'd also appreciate instruction on how to revert back to this older version if I need to later.
I'm using a MacBook Pro with Mac OS X Version 10.5.8
2.53 GHz Intel Core 2 Duo, 4 GB 1067 MHz DDR3
Thanks in advance, and have a Safe & Happy New Year!

You can restore much of the look & feel of the previous version with these shortcuts:
ALT to temporarily display the menu bar
CTRL+B to show or hide the menu bar
CTRL+S to show or hide the sidebar
CTRL+/ to show or hide the status bar (won't hide for me on Win XP)
Click the magnifying glass top right and untick Search Entire Library to restore the old search behaviour
Use View > Hide <Media Kind> in the cloud or Edit > Preferences > Store and untick Show iTunes in the cloud purchases to hide the cloud items. The second method eliminates the cloud status column (and may let iTunes start up more quickly)
If you don't like having different coloured background & text in the Album view use Edit > Preferences > General and untick Use custom colours for open albums, movies, etc.
If you still feel the need to roll back to iTunes 10.7 first download a copy of the 32 bit installer or 64 bit installer as appropriate, uninstall iTunes and supporting software, i.e. Apple Application Support & Apple Mobile Device Support. Reboot. Restore the pre-upgrade version of your library database as per the diagram below (click on it to enlarge), then install iTunes 10.7.
See iTunes Folder Watch for a tool to scan the media folder and catch up with any changes made since the backup file was created.
