Ran the Thinkpad tools and it updated the Bios to 7CETD3WW. Now getting 0251 System CMOS checksum bad. Wondering if anyone else has seen this or may know a solution.

Did you try to load the default BIOS settings? If not try to enter the BIOS by pressing F1 before Windows start to load. When you are in BIOS press F9 to load the default settings, select yes to confirm and press F10 to save and reboot. Then you might have to go back into BIOS to reapply your custom settings (if you had any).
Did that fix the problem?

You could try to downgrade to the previous version or the version you had before the upgrade.
What is the type/model number of the R60 (format XXXX-XXX found on a sticker under the computer) and do you have a link to the BIOS version you downloaded?

Basically you download the previous version, burn to a CD, boot from CD and downgrade just like you would do when you upgrade. The procedure is the same as when you upgrade to a new BIOS version just that you use a older version of the BIOS. I did that recently with a W510 because of issues with the new BIOS. I have seen some BIOS versions where it's not possible to go back to the previous version, but then the release notes should have a note with this information.
