X41 gives Error 0187 and Error 0191

I get Error 0187 and Error 0191 when I fire up the X41.

System board replacement's recommended for both error codes.

I tried to change a BIOS setting to see if there's any change in
behavior. There wasn't any. The battery has kept good time until I
re-seated the CMOS battery. I also got a 0250 and 0271 error for
date/time and bad CMOS in addition to 0187 and 0191.

Can anything else be done about that EEPROM? I'd love to get this
dang thang fixed up. I also posted this on another mailing list.

Thanks for reading.

0187
EAIA data access error.The access to EEPROM has failed.
System board

0191
System Security. Invalid Remote Change requested.
1. Run BIOS Setup Utility. Then save current setting by pressing F10.
2. System board

0250
System battery error. System battery is dead.
Replace the backup battery. Then run BIOS Setup Utility to reset the time and date.

0271
Date and time error. Neither the date nor the time is set in the computer.
Run BIOS Setup Utility to reset the time and date

So:
Replace the cmos battery and reset time and date in bios.
Try flashing the bios to the latest version.

Can I still update the BIOS despite the 0187 and 0191 messages? I'm under the impression I can't, but I'd love some guidance since I prefer not to flash a laptop BIOS.

Better yet, I'm wondering if I can reflash the same version BIOS, too.

A lot of these bizarre errors are caused by a low CMOS battery or a bad conncection to the battery. Maybe re-seating it didn't work/made it worse?

Looks like I'll have to replace the whole battery instead.

What size coin battery would I need? All I know is that the TP 600 uses a CR2025 battery. I'm presuming I can perform a similar replacement procedure instead of purchasing a complete battery/wrapping/wires/etc.

crack the thinkpad open and take out the battery. the type will be stamped onto it.

... but I'm still getting 0187 and 0191 error codes.

I replaced the CR2025 battery, but kept the wiring and wrapped everything up with electrical tape.

I got the time and date errors and they disappeared after setting the date and time. Errors 0187 and 0191 persist.

What else can I try at this point?

Thanks again for reading!
