XP Won't Boot Motherboard Battery Replaced

August 10, 2009 at 09:29:37
Specs: Windows XP
A friend game me his old PC 2.53 GHz P4 but the battery on the Motherboard was dead.On bootup, the CMOS reported a power management error and took me into CMOS settings where I abandoned changes and continued. Windows XP Home booted ok but gave two readings of processor speed on my computer properties: the correct 2.53 Ghz and a lower 1.92 Ghz.
Next time I booted, I changed the CPU speed in CMOS to 2.53 Ghz. Windows booted ok and now reported both speeds of 2.53 Ghz. Great! All I needed to do was fit a new battery, save these new settings and everything would be ok.
But no. On replacing the battery, XP hung on the loading screen immediately after the keyboard lights flashed. When booting from XP on CD, XP displays loading messages at foot of screen, then machine powers down before I can read the 1st blue screen of text (which has an F3 option - cannot read it because it disappears too quickly).
Replacing the good battery with the dead one and leaving power off overnight still causes XP to not load. The CMOS seems to have reset the CPU speed to "manual" (1.92 Ghz) as per when I first obtained PC from friend. So having set the system back to its original state, I still cannot get XP to load. The only thing I can think of is that some setting has been retained when the good battery was used and is conflicting with XP. Can anyone help?

You do NOT have to reinstall Windows...put the CD away. You know what the problem is, don't make matters worse.

Make sure you unplug the power cord 1st, then remove the battery for a few seconds. Replace the battery, plug in the power, bootup & immediately enter the BIOS. Change the date/time settings, then load the BIOS defaults. Save the settings & reboot. Enter the BIOS a 2nd time & manually configure the CPU & RAM settings...save your settings & reboot.

I've managed to get XP running eventually. 1st without battery by setting cpu speed to lowest. Then added battery and repeated. Couldn't get windows to boot with higher speeds. Something (windows or CMOS) seemed to recalc processor to correct speed as now windows boots showing both speeds of 2.53GHz and settings are retained after power off. I've not altered any memory settings but will start testing computer shortly. Thanks for all your help.
