When I turn the machine on it freezes after the IBM Thinkpad Logo screen and shows ERROR 0175: BAD CRC1, STOP POST TASK. I've done quite a bit of research on this error online and on the forum here. After initially calling IBM support, they recommended that I buy and replace the CMOS battery. I replaced the battery yesterday, but I'm still experiencing the same error and the machine is still failing to boot properly. I now suspect that there is a malfunction with the system board. I researched and found another site last night (www.allservice.ro) that offers software to fix this CRC1 Error, but this requires soldering the eeprom chip underneath the RAM cards, providing a dump and rewriting the eeprom. With my lack of computer hardware experience, I'm afraid that if I do this, I could permanently damage the machine. I located one person, who was very highly recommended, that can repair the CRC error for $100 or replace the system board for $200, but this is without any guarantees that the CRC error will or will not return. Does anyone have any new advice on fixing this BAD CRC1 error for the T series? Is the cost of this repair worth it....? If not, I am considering buying another T21 and inserting my old hard drive into the machine for

On bootup it gets ERROR 0175: Bad CRC1, stop POST task. In looking up google I have found an IBM solution to upgrade the BIOS to the ibm thinkpad latest solution. My problem is I do not have password information if it is required. I am interested if anyone has used the procedure and whether it works. It warns that you cannot stop haf way as you may do hardware damage. http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-44186 thanks in anticipation Russell Russelllk, Dec 17, 2004 #1 Sponsor rockinmale Joined: Feb 7, 2003 Messages: 728 Im sorry, i hate being ibm thinkpad error the bearer of bad news. The error 175 (Bad CRC1, stop POST task error) your receiving is not good at all. The only corrective action that ibm states about this error is to replace the system board/mb. A bios update is useless if the system board is faulty. Since you need it to post in order to install the bios update from a floppy. Here's a link to your error on the ibm website to see for yourself. http://www-1.ibm.com/support/docvie...-4K2MCU&loc=en_US&cs=iso-8859-1&cc=us&lang=en Im sure the term FRU may sound alien to you, but it stands for field replaceable unit. I did a search on ebay and found some t22 system boards for around $100. Although, i dont know if you can handle swapping out the motherboard. Since laptops are more delicate and trickier to work on than a normal pc. So its basically your call if you wanna try to replace the system board. Although, i cannot guarantee that this will fix the problem. Im sorry for your loss, but at least now you know what's wrong. Good luck!

It hangs the with error: " 0175 : Bad CRC1, Stop POST task" . Does anyone know how to reset the CRC Checksum on the mainboard? Any help would be greatly appreciated. Cheers, Fausto 10-01-2003, 01:11 PM Ol'Tunzafun I don't think this is going to be as simple as resetting CMOS, which you could do by removing the button cell battery from the motherboard while you are gone to the store to get another (typically a CR2032) battery. By the time you return to replace that battery, the power sustaining the CMOS program will have drained and CMOS settings will revert to default. Whether or not this solves the problem, the cost is minimal and it will possibly save problems in future. Having said all that, in view of the fact that it will not complete POST, I would surmise that this is a BIOS checksum error rather than a CMOS checksum error and you will likely have to reflash the BIOS. If you have not done this before, follow the "readme" instructions to a tee, although the IBM process seems to be quite straight forward. http://www-3.ibm.com/pc/support/site...GR-4JWNJC.html 10-01-2003, 01:39 PM fausto I understand your point ... I dunno how I can flash my BIOS since that machine freezes B4 it gets to the the floppy seek stage :( ... I am trying to avoid replacing the board. Any more suggestions? Cheers, Fausto 10-01-2003, 02:26 PM Ol'Tunzafun The BIOS ROM chip is usually replaceable. You can send them away to be reprogrammed or replaced. Wimsbios would be a good place to start looking for options. I notice that they have a link to Badflash which sells replacements, if it comes to that. 10-01-2003, 02:26 PM Baddog http://www-3.ibm.com/pc/support/site...id=MIGR-4PEN8X :( 10-01-2003, 02:59 PM Ol'Tunzafun Quote: Originally posted by Baddog http://www-3.ibm.com/pc/support/site...id=MIGR-4PEN8X :( Your manual suggests the same thing that Baddog's reference does - replace the system board, which suggests an "integrated" ROM chip.
