Need help with new battery installation

fireberd said:

When you replace the CMOS backup battery, you will lose any custom settings in the BIOS and it will be reset to the default settings. Thus, before you change the battery note any custom settings so you can enter them again after the battery replacement (and reset the date/time).

I use the Optimized defaults in the EZmode setup(basic motherboard settings),and i don't go into the advanced settings and change anything there.If it ain't broke don't(try to)fix it!.

I have took note of my boot settings in the advanced settings just to be sure.

Do you have any Linux installed?

No,Linux isn't installed on my PC.

Thanks for you quick reply.
The reason I asked is because some Linux did cause Windows 7 bios time problem.

I didn't know about that,thanks for the info.

I just want my PC to boot up as normal and not be troubled by the American megatrends screen and then going into the BIOS setup program.

As long as i don't have reset the motherboard settings using jumpers.That sounds too complicated for me!!.

Thanks

Spending time at my Girlfriends for a couple of days.Will put the new battery in on the 14th,and hopefully it will go okay...

I am going to put in a new battery,but will i get the same American megatrends screen?.

The first time you boot after replacing the battery, you likely will get this screen and you should immediately enter the BIOS Setup Menu at that time.

Reset your system clock for the correct date and time (including time zone), check or reset your "boot order" to make sure your boot disk is above other disks, them make sure you select "Save and Exit" to save the changes, exit the BIOS Setup menu and boot normally. You may still get the American Megatrends screen, but hopefully it will not indicate any errors and your time will be right.

Just be sure BEFORE you remove the old battery that you unplug the computer from the wall, then touch bare metal of the case interior BEFORE reaching in to discharge any static in your body. Observe the battery polarity (orientation in holder) before removing. The battery is most likely a CR2032, available at most battery/watch/camera counters. Do NOT touch the new battery with your bare fingers as skin oils promote corrosion and attracts dust. I put a clean cotton sock over my hand. And once again, touch bare metal of the case interior BEFORE reaching in. The battery holder is designed so the battery can only be inserted the right way - but it can be forced in wrong if too much force is used.

Also, while the case is open and unplugged, make sure the case interior is not blanketed with layer of heat trapping dust. Clean if necessary while frequently touching bare metal of the case interior to keep static buildup at bay.

Doesn't your MB has an option to save profiles to an external media?
If it does, save your BIOS settings as a profile file, change your battery (CR2032?), enter your BIOS and load the saved profile. You will have adjust the clock.

Just to explain: Hardware clock on Windows is equal to local time. In Linux, hardware clock is set to GMT and showed according to time zone.
