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 recovery. Will my hardrive (Hitachi Travelstar

This error is generated due to a couple of different reasons. First, there may actually be a problem with the power circuitry and the CRC function is actually doing it's job reporting the error. There are several http://www.hardwareanalysis.com/content/topic/31761/ tests you can perform (described below) to tell if this is the case with your system. Second, this bad CRC error can be generated by sudden power loss to the system, especially if the system loses power during boot up or POST process. If this is the case with your system, we can repair this error. There is some work involved and the cost mentioned below is well justified. Below is the standard reply email that we send to CRC inquiries that will hopefully help you determine if your system is a good candidate for a CRC recovery. ========================================= In some rare cases there really is a problem with the system board and the CRC checksum routine is actually doing it's job. If this is the case, you will see erratic power behavior, random shutdowns / freezing / erratic power behavior on power up, before the CRC error surfaced. We cannot guarantee our CRC correction will last when power problems exist in the motherboard. Unfortunately, we cannot refund the CRC recovery cost. Our time is money and the programmers we hire to correct the CRC information cost money. With that said... Most of the time, CRC errors are generated from a password removal attempt or sudden (user created) "Shutdown" or "Restart" condition and these situations are repairable. How c

The http://thinkwiki.de/0175:_Bad_CRC1 machine is running XP Professional. 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 latest solution. ibm thinkpad 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 the bearer ibm thinkpad 0175 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!

wichtigen EEPROM-Chip (ATMEL 24RF08) korrupt sind. Beim Auftreten dieses Fehlers weigert sich das ThinkPad, weiter zu booten. Ursache Der Fehler kann dann auftreten, wenn bei dem Notebook nach dem Anschalten während des POST die Spannungsversorgung zusammenbricht, z.B. aufgrund eines defekten Akkus, oder wenn bei Netzbetrieb ohne Akku der Strom ausfällt. In Einzelfällen kann dieses Problem auch im laufenden Betrieb "aus heiterem Himmel" auftreten: der Bildschirm schaltet ohne ersichtlichen Grund aus alle LED gehen bis auf Akku- und Power-LED aus Rechner scheint eingefroren, auch "blind" ausgeführte Aktionen führen zu keiner Reaktion des Rechners Rechner lässt sich nicht über die Powertaste ausschalten nach Abziehen des Netzteils und Ausbau des Akkus zum Abschalten erscheint beim nächsten Rechnerstart die Meldung "0175: Bad CRC1, stop POST task" Wenn dieser Ausfall während des Schreibzyklus des 24rf08 auftritt, kann es sein, dass inkonsistente Daten auf den EEPROM geschrieben werden, was dann beim nächsten Boot zum "Bad CRC1" (falsche Checksumme) führt. Dieses Problem tritt gehäuft bei den ThinkPads der 2X'er Generation mit Pentium III Coppermine Prozessor auf (A20-A22, T20-T22, X20-X21). Für diese Modelle wurden von IBM BIOS Updates zur Verfügung gestellt, die diese Probleme verbessern sollen. In den entsprechenden Changelogs des BIOS findet man den Hinweis: * (New) Update POST 175 error check routine. Die Mainboards dieser ThinkPads basieren alle auf einem Layout mit den Spannungswandler ADP3421, der des öfteren defekt ist und dann entweder zum Blink of Death führt, oder im Frühstadium, wenn die Spannungsversorgung nur sporadisch einbricht, eben den "0175: Bad CRC1" Fehler hervorrufen kann. Reparatur Der Fehler kann durch Neubeschreiben des ATMEL EEPROMs wieder behoben werden. Möglichkeiten dazu werden von verschiedenen Anbietern im Internet offeriert; es gibt auch eine DiY (Do it yourself)-Lösung, die etwas Löterfahrung und eine entsprechende EEPROM-Schreib-Software voraussetzt. Falls der "0175: Bad CRC1" Fehler durch einen "sterbenden" ADP3421 hervorgerufen wurde, ist diese Reparatur natürlich nur zeitweilig; gegen eine zusammenbrechende Spannungsversorgung hilft auch nicht das BIOS Update. Der ADP3421 sollte in diesem Fall ausgetauscht werden oder zumindest mit einem Widerstand versehen werden. - Siehe hierzu: BoD Weblinks Blink of Death-Reparatur (im ThinkPad-Forum) BoD Mit Anleitung zur provisorischen
