IBM T-20, EEPROM checksum error on POST ??

Archived from groups: comp.sys.laptops (More info?)

Anyone know how to fix this,
On start up I get
ERROR CODE 0175, CRC-1 error.
That is a EEPROM checksum srror.
What do I do?
I need the info from the harddrive!
Thanks,

There is an easier way to get the info off of the HDD. You can buy an
inexpensive adapter to fit 2.5" drives that let you use a standard IDE
cable and connect it to a desktop. Set the jumper on the laptop HDD to
Slave if necessary.

It sound like a dead CMOS battery which aren't too difficult to
change. Check out the TP News Group at ibm.ibmpc.thinkpad and also
the Forum and thinkpads.com

Good luck

Chas.

For fixing eprom checksum errors you can check out this site:

http://www.ja.axxs.net/unlock/crc_repair.htm

As others have said, you can always hook the hard drive up to another
computer to get the data you need until you get your laptop operational
again.
