I've seen several T20 series with the same problem. A CRC error pertains to a chipset on the motherboard, and the only way I've found to fix a CRC error is to replace the motherboard.

My ibm thinkpad a20m has a problem of error 0175 CRC stop post task, it hangs at dis state, i tried to replace the cmos battery and nothing happens any other solution for this? pls help me pls?


This is a common problem for A20's. It's a bad EEPROM or a bad M/B. IBMs resolution is to replace the board. please see link.

Also found this link with some tests you can do to find out if it's the board or the EEPROM. Either way it's not a simple fix. Please click here. There is an offer for repairing the EEPROM in this link. Posting the link is purely for informational purposes. Please do not consider it an endorsement of any kind.

You obviously didn't read the problem carefully. The machine won't boot, so there is no command line. I have the same problem with a T23. It might be the CMOS battery that needs to be replaced.

Post problem


If it beeps (which it should) means that some device did not pass post. Find your motherboard online and look up the beep codes. This should help you to discover the problem. I hope this helps!

Ibm t22 thinkpad laptop error 0175 crc1


Ok hm...

Sounds expensive, I'm afraid!

Here is IBM'smag-glass_10x10.gif explanation of the error codes.

What your machine is telling you is that a chip on your Motherboard is faulty and the only way to repair it is a new system board.

It is probably worth finding out how much IBM would charge you to repair it but I very much doubt you'd get much change from £500.
