    I did not replace the Laptop bat. but I did replace the CMOS bat I coulodn't find the exact one Maxell ML1220 but did find the cross ref to Energizer 1216, after replacing the bat, I did download from acer the win BIOS ( the flash program) as well as the latest BIOS version, when attempting to install it, it stated that the BIOS was already that version and wouldn't continue. is there a jumper? where if so, I just got this a few days ago ( 3rd owner) and honistly know very little about laptops, they aren't like the PCs that I build, I've only poped the case just enough to see and change the CMOS bat, and thats about it. so I dont know know to take it all apart.. I ordered the restore set, so Id kinda like it running right before I use it, I have a temp OS on it now... should I go in and use defaults? just not sure I guess, Ive never had this issue before that wasnt fixed with the bat..

Advent 5431 date keeps changing back to 2008

IS your TimeZone is Correct?
Right click on your clock, choose Adjust Date/Time.
Click Time Zone Tab. Make sure your Time zone is correctly set.

Boot into the BIOS (setup) screens and check the date and time there. If the date is off by years then that verifies you need a new CMOS battery. Do not confuse the CMOS battery with the large external battery you run the computer with.

Date time not set

When you change the date and Time to the correct Date and Time and when you next boot up the laptop the Date and Time is lost. Then this is caused by a flat BIOS battery which cannot keep these setting stored in the BIOS.
Replace the BIOS battery then go into the BIOS setting to set the Date and Time and this will fix your problem.

Laptop date and time setting get disturbed automatically when i reboot my laptop

When you boot up and the Date & Time is wrong then you correct the Date & Time, then when you shut down and boot up again the Date and Time has changed. This is an indication that the BIOS battery is flat and you need to replace the BIOS battery. Install a new BIOS battery, go into the BIOS setting and set the Date & Time etc. and the new battery will keep your settings stored in the BIOS.

Evo N610c doesn't keep time or settings in bios.

did you ever save the changes?? for any changes you do in bios you have to save them at the finish by engaging the F10 and Y for yes as in confirm ..
there is no other thing hat may stop you from making changes..either the battery is gone ..and in this case it will not hold even the date or clock ..and you will need to set them each time you start ..(also file association and other changes you make in computer on the settings level ...0 so if the battery is ok ..probably the saving changes is to blame it proper cause on some is the F10 key and Y to confirm ..and some just ask you on exit and you have to select the proper line for to save the changes..

When the power comes, my l-top doesn't keep the day/time, reseting itself to year 2001. I inserted a new battery, but looks like the date/time have its own source for keep working. It's true, is an old...

To determine if the battery is providing power to the CMOS, insert other changes to the bios besides time.
Like enable certain features and then power on, then turn off.
If the next time the date falters, go into the BIOS, and see if the changes you made are still there.

If they are, it is not your battery. If they are not, remove your battery, clean the terminals, (check the new battery is good) and reseat it.

michrophone may be related to the BIOS resetting. (solve one problem at a time)

Hi. The clock on my Acer will not keep the correct time any more and it doesnt change dates on the calendar either. Do I need to change a battery in my motherboard?

If you change the BIOS date and time and when you boot up next time and the date and time has changed back or is incorrect, then the most likely fault is a flat BIOS battery. Replace the BIOS battery, it maybe a coin type lithium 3volt battery. this is the most common type used in motherboards is a CR2030 lithium battery.

Inspiron laptop clock incorrect

Go into the BIOS by turning on the laptop and pressing F2. In there i believe on the main screen you can change the time and date. Do that, save changes and exit and then go into windows and see if it keeps the right time and date.

Let me know how it goes.
