What is the problem....?
I am waiting for your valuable replies..
Thanks for advaced..
Thank you,

Answer is simple. Avoid E73/M73 and buy M83/93. They work at least. Regarding your problem - contact Lenovo support in UAE. I believe your E73s are still under warranty, so they should fix it.

  • There has been a signature failure in Think Centre M73

    I made a clone of Lenovo Think Centre M73 after I clone in Lenovo CPUs of the same type out the command "There has been a signature failure."
    if anyone could provide a solution

    Hello and welcome,
    I don't have a solution for you but a quick Google of  "clone There has been a signature failure" pulls up quite a few hits.  One common theme is that the wrong partition is set active.  Here are a two of the hits:

    I have replied to you three times now without reply. I DID NOT authorise a payment of £9.99 for NowTV. What is the solution to getting my money refunded. I think you assume I will go away after being Ignored. No I will not go away. I find now that you have DISABLED MY APPLE ID. Is this a punishment you use to anyone who takes up a stand against charges being made unauthorised on their account?. Please tell me why you have disabled my account. When will my account be restored? If not when will you refund ALL my purchases made to APPLE/ITUNES? I can then move on to another brand and hopefully better customer service. After reading articles regarding APPLE ID DISABLED it appears common practice from your company to DISABLE anyone's account if they question unknown charges. Please reply with your intentions regarding  the unauthorised payment and the DISABLING of my account.

  • Mt copy of lightroom 5 still thinks its a 30 day trial, even after entering the serial numbers

    my copy of lightroom 5 still thinks its a 30 day trial, even after entering the serial numbers

    you bought the upgrade version meaning you have a previously purchased lightroom.  after entering your lr5 serial number you're being prompted for that previous version's serial number.
    enter the correct number at the correct time and installation will proceed.
    if you made an error and do not own a previous version, Return, cancel, or exchange an Adobe order

  • Blank screen after rotating the display in Yosemite (MacBook Pro Late 2013)

    Hi,
    after installing Yosemite on my MacBook Pro 15" Late 2013 I have trouble rotating it's screen. After I launch Preferences and click Displays while pressing alt and command keys I see the list of possible orientations available.
    If I now select 270° the screen immediately goes black. To be clear: The display is not turned off like when the MacBook sleeps. It's still lit, but only shows a black screen. After turning the MacBook off by pressing and holding the power button I can boot and voilà, the screen is perfectly normal, showing everything rotated at 270°. If I reset to Landscape from there (i. e. 0°), I have no problem at all, everything still works. Setting it back to 270° again lets the screen go black again.
    I have an installation of Mavericks at my primary partition and it has no problems at all with rotation. Is this a known bug or can anyone confirm this behaviour?
    As a hint for others suffering the same problem: You can get around the hard reset by pressing shift-comand-q followed by enter key. This logs your user out of the system and gets you back to the login screen. This obviously kind of reinitializes the UI. After that, the display's rotation is working and you just have to login again.
    Even if this is some kind of workaround it would still be much more convenient not requiring this workaround.
    Thanks in advance,
    Oliver

    Hi,
    yes, I had the same issues here! My solution was to force the system to use the discrete graphics card instead of the intel one. Then you get some additional options for the resolution which are much more usable. If you need further infos let me know. I'm using the MacBook in a rotated state about 95% of the time and it works pretty well now (at least in Mavericks, where I also experience your described behaviour).
    Greetings,
    Oliver

  • Yosemite became terribly slow after connecting Thunderbolt display

    Macbook pro 2011 16GB memory, SSD (instead of HDD), OS 10.10.1
    After updating to Yosemite i realize that everything became very slow, all system is terribly slow. Finder, Safari, any other application. It doesnt matter what i use - OS X yosemite became unusable. In activity monitor - just after connecting THD kernel_task starts using 545% of CPU!!!!
    But  after disconnecting Thunderbolt display - everything goes back to normal.
    I try to disconnect al external hdd connected to Thunderbolt display - nothing change.
    I try to turn off transparency - also no effect at all, the only solution is not to use Thunderbolt display!
    Thunderbolt Bus:
    Firmware Version: 25,1
    Port Micro Firmware Version: 2.1.3
    Please anyone who had the same issue, can you advise something?

    TBD is updated to the latest fw, but in Thunderbolt section of system information i got "No device connected", but Graphic/Displays section shows Thunderbolt display Connection Type: DisplayPort

  • Right after starting up display goes blank and shuts down?

    Right after starting up display goes blank and shuts down?
    Any ideas I can't get it started. Thought I would ask for help before making a genius appt.

    Thanks that was very helpful info. I was able to boot into the recovery disk partition and run some basic HD tests and it found no issues.  Then I booted into the hardware test and it found no issues. After these tests it still failed to boot into Mavericks. I'm guessing its a software issue and I can not find the original computer disk. I have a time machine backup from 2 months ago and I could use the disk utility on the recovery sector to launch it but I want to wait and see if I can boot from a software DVD first. If I can repair the current OS that is my best option.
    Thanks.

  • Do you think USB SB series have better performana

    For SB series, there are actually internal and external types.
    USB SB Audigy 2 NX is an example of external SB.
    I used to think SB card is greater than USB one, as it has more functions than the latter.
    But after I have installed SB audigy 4 to my PC, I encountered problems that maybe due to electric field.
    A man from Creative Support Department has tried to answer me why there is crackle in the sound output with Electric Field.
    He suggested me have at least one slot space between the Video card and SB card.
    I adopted his suggestion, but the matter of crackle sound still exists.
    The conclusion is that USB SB series should not cause any any electric field to affect the sound output quality of the PC.
    So, why don't we choose USB Sound Blaster?
    What do you think?

    Right from the start, the ipad2 will run existing apps. In general, newly developed apps that take advantage of any new processor capabilities typically arrive slowly after the new hardware arrives. (not specific to Apple, but industry)
    If you see delays in processing when you use the original iPad, you may see snappier response with the faster processor. I don't see much processing delay in daily use of my iPad.

  • I think there is a very annoying bug after the latest update of firefox, can I talk to someone, or chat with someone so I can get rid of it

    Since the latest auto update of my firefox browser I am experiencing strange issues. Every evening when I stop working, I close my browser (closing all the tabs that I am working on and in the morning, I restore the session) . For many years everything worked just fine ... untill after the last auto update of the firefox browser .. all of a sudden a got 302 errors ( a blank page with the description 302 and I believe "page moved here" or something to that extend ... i try to click the link and get nowhere.
    I first noticed it on a few wordpress pages (backend ) that I was working on and which were restored from the previous day ...
    thinking it was a server error, since we have several vps and dedicated servers .. i contacted the company who hosts our servers ..
    they looked into it and apparently .. there were no issues on the server side and neither on that particular computer ... but our server hosts told us .. that it is probably browser related and seemed to have something to with a bug with the cache of the browser
    we didn't know what to do .. it was very annoying .. but at that point it only happened once on a hew pages .. so we decided to see what happened the next time
    Next time we did not restore a session with wordpress pages .. but with the google search engine open and on a few other tabs logged into social media .... and as was saidn by our server hosts it was indeed not related to work that we did on pages on our servers ... since that time even the google search engine homepage ... showed us ... moved here
    Can you pease look into it and fix this .. we are doing the same thing as many years on the same computer also a few years .. so it is not anything we do wrong either .. it is most definitely browser related
    so can you please fix it asap .. since when we work on wordpress .. that is not the only thing that goes wrong .. we also have difficulty uploading updates ... when updating sometimes after the update of any particular change on a wordpress page is done ... we are also redirected to a blank page .. so the updated page does not want to load ... in that case we have use our back button ...
    which sends us back to the right page ... but with the old data on it ... then we have to refresh that page .. and only then we see the page updated ... so it seems that there is an issue in both direction with the caching of the browser after the last update
    Kind regards,
    Robert

    uninstalled firefox ....deleted all files still remaining under mozilla firefox directory in program files ... to avoid having to reprogram all my settings, reisntall all addons as well .. I did not remove anything from mozilla firefox that is stored in either appdata or under the windows users directory (if any)
    ... the as suggested reinstalled the latest version of the firefox browser using the link you provided in the email ..; tested and several issues still remain present and unresolved ....
    so please this is urgent or I will have to jump browsers and start using chrome .. because we work 14 hours a day 6 (sometimes 7) days a week, to get ready for the launch of our newest venture and we cannot lose that much days on browser related issues ... so please instead of putting me through week long step process .. of do this .. do that .. can you please actually look into the issue from your end .. I use firefox for so many, many years thta I deserve this kind of support .. thnx Robert

  • I too had the same vertical white line in the centre of the screen last night after having my iPhone 5 up and running for 10 days. I managed to turn it off by holding the buttons in and it came up with the iTunes screen....2 hours later it came good?

    I was talking outside on my iPhone 5 in a fairly humid environment (The Pilbara in January, 2014) then when the call was finished I hung up (as I was walking back inside to the air-conditioning) this white vertical line appeared in the centre of the screen and wouldn't go away. I couldn't use it NOR could I accept calls. (I called my number from my other phone). I eventually managed to turn it off after removing the protective casing (Otter Box) and then it came up with the white cord / iTunes screen........I left it for a while...it turned back on BUT is still had a flickering screen.......I re-charged it and I have backed it up this morning (at work) on iTunes and it seems to be working 'fine.' All I can say is 'DO NOT GET RID OF YOUR SAMSUNG GALAXY PHONE IF YOU HAVE ONE!' I haven't had an OUNCE of trouble with it and have owned it for at least 3 years. The iPhone has been up and 'running' since the 6th of January, 2014. This happened on the 15th of January, 2014.

    Plug your phone into the wall charger for at least 30 minutes...make sure you have a sim card in the phone...then:
    Leave the USB cable connected to your computer, but NOT your phone, iTunes running, press & hold the home button while connecting the USB cable to your dock connector, continue holding the home button until you see “Connect to iTunes” on the screen. You may now release the home button. iTunes should now display that it has detected your phone in recovery mode, if not quit and reopen iTunes. If you still don’t see the recovery message repeat these steps again. iTunes will give you the option to restore from a backup or set up as new.
    Make sure you have no anti-virus software running or any firewalls...turn all of that stuff off.

  • HP continues to ship defective Intel 6 series chipset to customers after recall.

    Something folks should be aware of is that HP has instituted a "fix" that isn't really a fix.  I had a DV7T QE (product number XN093AV) that was ordered in January.  The laptop was affected by the chipset issue and after about a month of checking back with HP customer service I was finally told that they had a resolution and that I could exchange my machine for one with the newly revised chipset.  The replacement machine was delivered to me in mid March, it was the identical product number (XN093AV) and contained the identical faulty chipset.
    Some background for those not familiar with the chipset issue.  Intel initiated a recall of their 6 series (cougar point) southbridge chipset designed for use with the second generation core i-series "sandybridge" CPU's.  Among the chipset's functions is the SATA controller interface for storage devices.  The chipset manages 6 SATA ports, 2 at 6 Gb/s and 4 at 3 Gb/s.  It is the 3 Gb/s ports that are affected by the design flaw which can lead to data errors for an attached storage device.  Intel's mobile version of this chipset is called HM65 and the stepping (version) of the chipset with the problem is "B2".  Intel has implemented a silicon fix and released a new stepping "B3" which does not have the problem.  However, Intel has continued to ship the affected "B2" stepping to manufacturers for applications where only the 6 Gb/s ports would be used as they are unaffected by the design flaw.
    Back to HP's "fix" - my original machine had the faulty "B2" stepping HM65 chipset with a hard drive connected to a 6 Gb/s port and an optical drive connected to one of the faulty 3 Gb/s ports.  The replacement machine I received also had the same "B2" stepping HM65 chipset with both drives now connected to the 6 Gb/s ports.  Unfortunately this isn't an acceptable solution on at least two fronts.  First, in addition to the primary hard drive bay and the optical drive bay this particular 17.3 inch laptop has a secondary hard drive bay.  I have independently purchased an SSD drive that I intend to install in addition to the factory installed drives.  This requires the use of a third port which would have to be one of the faulty 3 Gb/s ports.  Moreover the laptop also has an e-SATA connector for connecting to external drives which I intend to use for backups.  I didn't verify this but considering that the primary hard drive and the optical drive are consuming the only two working ports it stands to reason that the e-SATA connector is connected to one of the faulty ports.
    After about 5 hours of being bounced around in the HP customer service void and being told that there was nothing wrong with my machine they agreed to exchange it yet again for one of the newly released DV7T QE models (product number XW899AV) which I am hoping will have the HM65 "B3" stepping chipset.  I haven't received it yet so I can't verify whether or not the new product has the same issue.  I will post when I do get it.
    Does this impact you?  You can determine which stepping of the chipset you have by running CPU-Z, a free and widely trusted system utility, available at www.cpuid.com.  Select the mainboard tab and look at your chipset revision.  If you have the "B2" stepping and you intend to use more than two SATA devices at the same time you may have an issue.  The following link outlines your options from hp.
    http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02712015&lc=en&dlc=en&cc=us&lang=en&product=505...
    I will point out that the answer to FAQ # 2 is definitively untrue.
    Is HP still making products with the affected Intel chipset?
    No. HP has stopped manufacturing products with the Intel technology at issue and has placed a shipment hold on products in HP and channel inventory.
    Good luck.
    This question was solved.

    Thanks for clearing this up Dan.

  • Satellite P850-31L thinks Intel HD GPU driver is old after Win 8.1 upgrade

    Hi there,
    I have had my Satellite P850-31L since last year and recently updated to windows 8.1.
    This laptop has a NVIDIA GeForce GT 640M graphics card and it use to say that on my dxdiag.
    Since updating to windows 8.1 my laptop seems to think I have a Intel HD Graphics 4000 and apparently it's out of date.
    When I go on their site to test for the update.
    I got told my graphics card is 'up to date' yet every thing else - including my toshiba driver manager says it's out of date.
    I've tried updating yet I keep getting a message saying my system setting aren't good enough.
    Anyne got any suggestions on what i can do.
    Can I get my laptop to stop thinking it has a intel graphics when it has the NVIDEA chip

    > defterniko
    After Windows 8.1 upgrade you should visit the Toshiba EU driver page and should update the drivers and utilities to the Windows 8.1 version.
    Most people forget to do that they update the system from Windows 8 to Win 8.1 but dont update the drivers.
    As mentioned by user IronMan; the installation instruction which is available on the Toshiba EU driver page shows you the driver and tool which needs to be updated and you should also follow the installation order mentioned in this instruction.
