System delay after replacing CMOS battery

This morning I was called to make a House Call for a computer member. It was
explained to me that he had been receiving some vague messages. He had
decided that it needed a new CMOS battery. On the way to the store he
dropped the battery that he had removed down along side the transmission
housing. So he simply guessed as to the replacement. When he had installed
it, the computer wouldn't boot. That's when I was called. After attempting
to start it, I very carefully explained that I would take it to our hardware
guru and that it appeared to be a power supply. This explanation took
several minutes, and Whoa! It started to boot up. Found some sort of error,
and I pressed on. The system booted up correctly. WinXP SP2. After resetting
the system clock all was normal.

Is this kind of a delay normal?

Some motherboards will not boot if the CMOS battery is dead or missing.
My guess is that the powered up state caused a capacitor to eventually
charge up that would then hold the values in the CMOS table copied from
the BIOS (from EEPROM).

You should be able to go online to the motherboard maker's web site to
read their online manual. Many mobos use the CR-2032 wafer battery.
Sometimes you can check the silkscreen printing inside or around the
battery holder to see a battery model number.

Did you short the 2-pin header to clear the CMOS table copy of the BIOS
(to force a reload of the default BIOS settings)?

What battery did he end up installing? The most common ones I have seen ar
CR2032 Lithium batteries. The one he put in may be the wrong voltage.

"...It started to boot up. Found some sort of error, and I pressed on..."

Did you make a note of what this error was?

I spoke with the member at Thursday's Q&A session. He has had no further
problems, except that the printer didn't work. I followed him home and
plugged the USB cable into the port.
