Default clock

When computer is on, exact time and date and displayed.
Shut down computer and turn on later, maybe next day,
time and date is way off.

The CMOS battery on the motherboard is weak and must be replaced.

Reboot the computer, enter the BIOS setup program, write down all the settings on
each available screen.
You then need to replace the CMOS battery on the motherboard, after which the BIOS
settings must be reset.

But doesn't the BIOS retain the data for half a minute or so, when the
battery is removed? (Not sure, just wondering).

It depends. Sometimes the motherboard circuitry has enough
capacitance (accidental or deliberate) to allow the clock
to continue and the CMOS RAM to retain its settings for a
short period - some people have reported days, but that's
unlikely - even when the battery is removed.

It's possible, but it has never happened for me.

So have you really had to write down and use those CMOS settings in
practice, or has the system been able to get it pretty much right on its
own, after booting up? (Just wondering - haven't been there yet). ??

Hi Bill,

Depends on the age of the machine, in my experience. Fairly modern systems
will probably be in a working condition, with sensible(ish) defaults set for
most options apart from date and time. IDE devices will probably be set to
auto detect, so hard drives, CDs etc should be found. But sensible(ish)
isn't the same as optimal. If the BIOS lets you adjust the CPU settings, for
eg, then it may well be that the default settings will be adequate to get
the machine to boot, but will be far from good.

On really old machines, you had to set pretty much all the options by hand,
including the hard disk parameters and interrupts etc. Even on newer
machines you may well lose any particular tweaks that have been made.

So I'd say yes - if the system is behaving reasonably well, it's always
worth spending a few minutes jotting down those settings. If it turns out
you don't need them then that's great. But if you do, those few minutes
might save hours of experimenting while you try to figure out what needs to
be changed. Been there, done that, wished I'd written it down before I
started:-)

That said, in a situation like the OP, where the clock is always wrong when
the system is powered up, I'd be tempted to think that other settings might
be equally corrupt and that the system is already using sensible(ish)
defaults for most things. That's just a guess, though - anyone have a
definitive answer to that? Either way, it doesn't hurt to err on the side of
caution and make a note of those settings!

Rob.

Yeah, thanks. I think so too.

You would have thought it would have been possible for the BIOS
manufacturers to add the capability of sending that BIOS info to the printer
as simple text, or save it to a disk file as text so you wouldn't have to
tediously write it all down.

Or maybe the BIOS can't do that alone (it doesn't know how to properly
access the printer, and/or save a text file, with the BIOS data)? I
dunno.

Actually, for a while some older BIOS' (AMI, I think...I don't remember) had an
option to print right in the BIOS menus. The problem these days is that many (most)
printers won't even print from a real-mode (DOS) boot, let alone from the
BIOS....they require OS drivers in order to print. I have an older printer on the
parallel port (an Epson Stylus Color 640 ink jet) that will respond to the
PrintScreen key from the BIOS setup screens, and print out (badly formatted) each
screen. Most modern printers will just sit there and smirk.
There are programs that will save the BIOS info in binary form, to a file, but I
have not tested how well they work as far as recording *all* the info....something
to do in my non-existent spare time! ;-)

I agree that there should be an option to save the info as a text file, and don't
know if there is a technical reason to prevent this.
