THINKPAD 600 Error 187 (no enter to bios)

[Markus_M]

I have Thinkpad 600. If Power up i see Error 187. In list of errors in this model i no see this number. Enter to bios setup is not possible. I upgrade the bios using downloaded floppy image. Upgrade is succesfull but no fix problem.
Please help if possible.

I just did a Google search for any thinkpad model with error code 187. There does not seem to be any one listed. I did check error codes close to that number in hopes that I can find what it might mean. I think there is something wrong with the motherboard on the system. It must not be able to complete POST. It could be the RAM, but those errors are in the 2xx range. It could be something as simple as a loose jumper pin in the computer, so something that would result in a replacement motherboard. Is there another number besides 187 that could identify more clearly the problem. If you have 301 anywhere, its a keyboard error and I think 187 might be used there, but not sure. Strange, but hopefully someone can figure this out.

A simple search at the IBM/Lenovoweb site for:

finds this page at the top of the list:

Numeric error codes - ThinkPad General

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

This type of failure generally means that the system board needs to be replaced.
