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

Hi,

 

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

Keeps resetting to the BIOS default time ( 00:00:00 at 01/01/2009 ) ..OR.... a time 'near' what it is supposed to be..

 

 

MAIN STEPS IN DEMONSTRATING THE ISSUE ...  WHAT I HAVE DONE

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

Main attery back in again.

Changed the BIOS time (using F2) countless times, but it rarely stays / or is correct.

 

 

STRANGENESS..

When booting into Windows 7, it nearly always does not show the same date and time that I entered in the BIOS.

For example if I enter 21:35:00 on 28th August 2014 using F2, when I boot into Windows the date and time may say 23 August 2014 at 15:25 ish..

 

 

TURNING OFF

If I power down and turn off,  and then power up, restart the time in the BIOS is correct.. at 21:43:00 08/29/2014 (which I save just for good measure). 

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

 

 

ADJUST WINDOWS TIME (UK)

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

 

JUST FOR INFORMATION: The TIME ZONE SETTINGS are checked and no changes made : (UTC) Dublin, Edinburgh, Lisbon, London

CONTROL PANEL, REGION AND LANGUAGE, English United Kingdom, Short time 21:48, Short Date:: 29/8/2014

LOCATION: United Kingdom

i.e. All appears now to be correct.

 

TURN OFF AGAIN and I wait a few minutes.

 

TURN ON AGAIN and press F2 which (this time) shows the BIOS Default date and time in 2009

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

 

:-(

 

That's about it.

 

I would really appreciate help fixing this problem which is driving me nuts !

 

Thanks in advance !

    ...   Just in case anyone reads this...   Woman LOL

     

    I simply updated my BIOS to the next issue, and the problem went. 

     

    I guess maybe the BIOS had got corrupted !

     

    I used the simple appraoch, and no shorting of terminals was involved.  I deliberately did not go for the latest BIOS just in case it brought new issues and confused the situation.

    Hi,

     

    Sure...

     


    I went to www.acer.com ...   then Support ....

    Which redirected me to ... http://www.acer.co.uk/ac/en/GB/content/support  here in the UK...

    Near the bottom of the page is 'Drivers and Manuals'

    I clicked on 'Search by product' and typed in 5472Z and clicked on the SEARCH button...

    This gave me..   Aspire 5742Z  Aspire 5742ZG;  TravelMate 5742Z; TravelMate 5742ZG... etc

    I clicked on Aspire 5742Z and this gave me headings such as DRIVER; DOCUMEMNTS; BIOS; PATCH; APLICATION; OS

     


    I clicked on BIOS and saw...

    'BIOS     Acer     Fixes sometimes system time will be set to default value.     1.26     6.7 MB     2011/11/14     Download'  ...   which was very close to what I was looking for.

    Hope that helps!

    You are welcome. 

     

    I know how frustrating it can be - especially when in a panic/hurry

     

    I thought it would be a good idea to repost the link instructions, as there may be others in the same boat.
