Why my calendar and time changes each time I have logoff my computer

Original title: Date/time

Why my calendar and time changes each time I have logoff my computer? Sometimes, it will change a year totally false and an incorrect time?

It could be the button for the CMOS battery.

A low CMOS battery can sometimes various issues, including slow, locking unexplained performance issues as well as others.

It is quite rare, but the battery is relatively easy to replace, check the manual of your computer/motherboard for replacement details.

Generally, the battery is a watch battery "CR2032", about the size of a nickel.

    Why the date and time is wrong when I start my computer

    CMOS battery die/of - usually about the size of a quarter on the motherboard of your system.

    It keeps things when you are not using the computer - if it starts to die/dies - then the time is no longer maintained.  Replacing, it is no different (in most cases) that replace the batteries of your TV remote or FOB car key.

  • Display of the Z10 Z10 blackBerry calendar and time are not (closed by 1 hour)

    I live in Saskatchewan and have my Z10 date and time set to Sask-6. I'm going for the calendar, create a new event, enter the time as 07:30 and save. The calendar shows the event at 08:30. If you select the item and edit it, it is properly the list at the time as 07:30. I guess that there is a bug with the time (time never changes in Saskatchewan), and I can't find any setting to disable the time change.

  • I just had to activate my Windows Vista via the phone. Can I do it again the next time I have reformat my computer?

    I once invited by Microsoft to activate my windows vista using phone... Thus, you will be asked to activate windows vista by using phone next time I have reformat my laptop?

    It is likely, but maybe not.

    Sometimes the internet activation works but stops working if you activate the product too expensive.

    For example, I reinstalled Windows and Office 5 times (on the same computer) in 2 weeks before and the activation of the internet has stopped working so I had to activate by phone.

    However a few months later the line internet activation reworked.

  • Evrytime I connect me, I have to reset my date and time, why?

    Why my date and time do not be saved? Why should I reset each time my date and time?

    Hi NarendraNP.

    Here are three possibilities about why this is happening to you.
    1. The time in the BIOS is not set correctly. Therefore, every time that you start the PC the incorrect time is displayed. To correct, shut down the computer, turn it on and immediately go into the BIOS settings. Check that the date and time is defined, save and exit, then start the computer normally.
    2. The CMOS battery is dead and needs to be replaced. To fix, you have to expose the motherboard and replace the small type CR2032 on motherboard. You can find many videos on YouTube that will show you how to replace a motherboard CMOS battery.
    3. You don't have administrator rights to the computer to change the date and time, or there is a program installed on the computer that locks the system setting changes (an example of a program that does this is Faronics DeepFreeze). The only solution for this is to temporarily disable the program that is to lock the Control Panel, or ask a system administrator set the date and time for you.
    One of these explanations\fixes help it?
  • Changes of date and time when you go to the line

    On the date and time to start on the computer is fine.

    When I go to the line for a unknown reason date and time moves forward 12 hours. This happens not always as some time it will be presented one, two or three days without change.

  • Setting date and time for several photos

    Thank you for providing the space for new users and thank you in advance for your help.

    Currently, I'm moving across lightroom and apple aperture/iphoto 5.

    The part of OCD I like to have my library organized, and I noticed that when I transferred my library everywhere he is in a bit of a mess, so I'm currently putting together the library and it cleaning (around 18000 photos)

    Anyway, I almost settled on a folder structure (YYYY/MM - I for the number of photos I have try on the nut until days could be for many - happy to receive Advisor on it also)

    For the most part, the photos have the date and time of the beginning of the digital age (for me from 2006)

    Photos prior to 2006 are in the negative, and I am currently underway with these scanned and imported into the library, I have a lot each month.  Set the date and time from the date of creation, this is where I am running into trouble.

    I looked around the web and various forums without success.

    First of all, I organize the pictures in the correct order.  Then I select the first photo and then select it the remaining photos.  I then select the date/time setting in the menu and select the first option, ajuster to adjust to the new date and time, say on 01/01/1990 to 1200 hours.

    The result I get is the first photo (the photo so good term) 01/01/1990 @ 1200 as the date and time, others have 01/01/1990 Date (if I'm lucky), and the time of jumping around.  Sometimes it wont even change the date time for the remaining photos.

    What I want to achieve is the time even for all the photos when I select a lot, or increment in time by a lump (is to say 1 minute (1200/1201/1202) or 1 second (1200:00 / 1200:01 / 1200:02)) and I seem not to be able to work it to do this automatically, currently, I have to do this by adjusting each photo (some 200 at a time) which is really manual labor)) intensive

    Thanks in advance and hoping an easy solution

  • Date and time system continues to change each time the system starts.

    I noticed that the time and date of my home PC gets changed every time the system is booted. The default date is set for Jan. 2008, when in fact it should be July 2014.

    Also, my PC became slow death. I use Windows 7 on 1 GB of RAM, 250 GB PC. I used last my home PC 2 years back, but there has always been someone to use it.

    It shows the OS disk to 7 GB of free, when in fact I never installed or anything unnecessary stored on the disk of BONE; Whatever unnecessary programs were there, I uninstalled them recently, keeping just a few essential ones. After uninstalling, it shows to 7 GB of free, when in fact it should be more than that.

    I use Avast anti-virus, which I think is unnecessary, that its not to protect my PC and as other programs, too, is quite dead slow.

    The system is infected by viruses? Manually, I checked the system for viruses and clean the system of all unnecessary and, program files, but I'm still not sure whether it is a virus or a PC problem.

    I am a COMPUTER analyst, and's just done it 2 days that I use my PC at home. I could format my PC, or where applicable be buy Windows 8 with a new processor.

    Please advise.

    Thank you and best regards,

    Hello

    You really need a minimum of at least 2GBs of RAM to run Windows 7 well enough.

    As you have only 1 GB of RAM, which seems to be one of the reasons why it is slow.

    Increase the physical RAM or try ReadyBoost:

  • Why changing Date and time?

    Hello
    Initially, I had a problem where one of my hotmail email accounts wouldn't sync and it came to light that my date and time were wrong. I don't understand why my time and date have been late and not the correct time and date. Is it possible that I can know why it happened or repair. The time and date are ok now.

    The date of his computer does not change since 01/01/2008, today's date. After the formatting as system, it is facing the same problem. He tried to change the date through the configuration of the BIOS. But after the reboot, the date is still helping 01/01/2008.Please. He got windows 7 ultimate SP1.
