I have a DATE TIME / CMOS / BIOS with my Acer Aspire 5742Z problem

Hello

Newbie here...

I have a strange problem with my Acer Aspire 5742Z (UK), which I think may be the BIOS or CMOS area...

MAIN PROBLEM

Guard reset BIOS default time (00: 00:00 on 01/01/2009)... OR... a time '' close '' to what it is supposed to be...

MAIN STEPS IN THE DEMONSTRATION OF THE ISSUE...  WHAT I'VE DONE

Removed the main battery and then replaced the CMOS battery twice (in the case of a failure)

Main battery insert it again.

The clocks of the BIOS (using F2) countless times, but there's rarely / or is correct.

STRANGENESS...

During startup in Windows 7, it almost always does not show the same date and time that I entered the BIOS.

For example, if I go home at 21:35 on August 28, 2014 using F2, when I boot on Windows, the date and time may say August 23, 2014 at 3:25 pm ish...

POWER OFF

If I turn it off and turn off and then turn on, restart the time in BIOS is correct... to 21:43 29/08/2014 (that I have record for good measure).

If I continue, Windows reads now August 23 at 15:32

ADJUST the WINDOWS TIM E (UK)

So, then I change the time of Windows Date to Friday, August 29, 2014 21:48.

JUST FYI: the PARAMETERS of ZONE SCHEDULE are checked and no changes: (UTC), Dublin, Edinburgh, Lisbon, London

PANEL, LANGUAGE AND REGION, English in the United Kingdom, short time 21:48, short Date: 29/08/2014

GEOGRAPHICAL area: United Kingdom

now, everything seems correct.

TURN OFF AGAIN and wait a few minutes.

YOU turn it back ON, and then press F2 that (this time) shows the BIOS default date and time in 2009

If I continue in windows without changing the BIOS date and time dafault, Windows now displays as 23:02 31/12/2008

:-(

That's all.

I would really appreciate help fixing this problem that makes me nuts!

Thanks in advance!

...   Just in case anyone reads this...

I just updated my BIOS for the next issue, and the problem has.

I guess that maybe the BIOS got corrupted!

I used the simple approach and no short layout has been involved.  I deliberately did not go for the latest BIOS just in case where he brought new questions and confused the situation.

    Have you tried to remove the battery and power. Press and hold the power button to try to reset the bios? Another option is to see that if you have a bios re - configure the jumper pins usually located in the compartment of the DRAM module on the bottom of the machine - it should be located somewhere on the outskirts of the DRAM module, so you should not remove the module.

  • Need help with an Acer Aspire 7741z-4643

    Hello

    I have a laptop of Acer Aspire 7741Z-4643. I got it for (I think) 4 years. I don't remember when I bought it.

    One day, when I used it just went completely black screen. So I turned it off and then back on and the screen was still black. Every time I turn it on the screen was black. It should start as usual and when she would get to the point where you connect to the computer it would go black. So I took it to my friend who works on computers and he said that my hard drive was dead. I replaced the hard drive with a hard disk of 500 GB of the playstation 4 that I wiped with dban.

    I can't use the computer because windows is stored on the old HDD that is dead and the new hard drive never had windows on it. I tried to turn on the computer and it says that no opperating system was found.

    I intend to make a windows 7 install usb using windows 7 usb dvd download tool from microsoft.

    But my problem is, I don't have my windows 7 product key, the sticker on the back of the laptop is faded and dissipated.

    My question is, is it possible that I can find my windows product key 7 directly from acer, using the serial number of my cell phone or my laptop snid?

    Thank you.

  • Problem with my Acer Aspire 5552-5686 and 5.1 Audio HDMI

    Hi all, I recently bought a SONY HT-SS380 Home Theatre, and I tried to connect it to my Acer Aspire 5552-5686 by HDMI port. (I have Windows 7).

    My problem is that I have can´t set up the laptop to use more than 2 channels (stereo). I ve been looking around the internet and there seems to be a common problem with this computer, but I can´t understand why or how to fix it.

    I ve tried to install the latest Realtek Audio drivers, the Catalyst Control Center, some Audio HDMI of ATI drivers. I Don t know what else to try!

    Any help?

    Thank you very much!

    This isn't the audio chipset of this system, which I listed above.

    The audio chipset to send the data in 5.1 surround.  The HDMI port would support, if it was sent.

    It is not sent in this way, I listed above.

  • Problem with my acer aspire 5750G

    Hello, good afternoon.

    My problem is that when you turn on the laptop. My monitor shows no sign or there is activity on the hard disk.

    I tried to remove the ram, HDD, the bios battery, connect it to an hdmi TV and still no sign of life.

    I think it's maybe corrupt bios. ¿Steps? Suggestions? help please!

    Sorry for my English (google translate)

    Thank you!

    From your first post, I thought you said when you tried to turn it on nothing happened.

    If it stays on when the memory is removed, but stop with installed, you may have a bad memory dimm. If you have 2 DIMM, try to start with one, then the other.

  • I need help with my acer aspire one ZG8

    I bought an acer aspire one ZG8 at a yard sale.  It powers on, but he seems to have no partitions.  My guess is that the former owner accidentally deleted the hidden partition.  I tried to install xp on it, but after that it is a preliminary Installation, it goes to the blue screen of death.  Help me. What can I do?  Do not have money to pay someone to fix it.

    Hello

    · What error message and the error code are you getting?

    As you get the blue screen during the installation of Windows, the problem is related to the material. I suggest you to replace the RAM sticks on the computer and check if it helps.

  • Worm: 38.4.0 e-mails have two date & time others have only once?

    This has also occurred on the previous 2 versions of the T-Bird

    Yes, the messages of today date is not displayed. It is all about the largest (and IIRC all of the future.)

    You probably captured this image today, 3 December 2015? Thus, it shows the date for messages which have been dated yesterday and the day before etc. Tomorrow, it will add the date to the messages that arrived today.

    Once you got used to the absence of date which means 'today' you will begin to appreciate the ease with which allows you to identify recent messages.

    You can change it. http://KB.mozillazine.org/Date_display_format
