Thinkpad a21e with error 271 (check date/time) and 188 (bad CRC2)

My Thinkpad a21e is refusing to boot, displaying the above errors instead.

I have seen some mention of a Hardware Maintenance Disk to restore the serial number, but I can neither find such a disk for this machine (2628-CXU), nor can I get into the BIOS.

I have also seen some mention of being able to have the EEPROM reprogrammed, which is alleged to be the source of the error.

Finally, I have seen an 'abandon hope' message indicating that the mainboard is faulty and need to be replaced.

Anyone with real knowledge about this out there ?

Hello,

The IBM A21 series is plagued with power circuit failure that usually results in the BAD CRC code due to erratic power behavior and failure.

We have repaired quite a few CRC errors on various ThinkPad models and every A21 we've done the error came back. We stopped offering the CRC recovery for the A21 series because of the low level of success. All the other ThinkPad models accept the CRC recovery and don't have any more CRC issues once the repair is complete.

You can,

Find the power problem with the motherboard and repair it. Then repair the CRC data to remove the CRC error message.

Or replace the motherboard.

I have seen a number of postings that state the same thing. Has anyone considered a lawsuit against IBM ? Toshiba paid heavily for a faulty floppy drive in their laptops - this is much more serious.
