Hello,

Some of the earlier IBM ThinkPad's developed an error message at boot with the following text:

ERROR
0175: BAD CRC1, STOP POST TASK.

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 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 can you tell if your ThinkPad is a good candidate for a CRC repair? We suggest you try the following tests:

1) Start the system and watch the status lights in the LCD hinge or near the power button. They should flash once (some models twice) before the system shows a display. If they flash 3 times or more, you have a power problem.

2) Start the system and allow it to reach the CRC “stop post task” error message. Let it sit at this error for several hours. The system should sit at this error for ever or until user intervention occurs.

3) Some things to watch for while the system is sitting at the CRC error and running for several hours would be: Screen going black, System rebooting, System powering off, ect.. ect.. ANY activity by the system is a warning that power problems exist in the system.

4) Try restarting the system several times consecutively, shut the system down by holding the power button for 5 seconds, then restart keeping an eye on the status lights for any additional flickers.

5) All the above tests should be done with AC power applied and battery installed. Also ALL drives installed.

If your system passes the above tests then it’s a good candidate for a CRC Recovery.

We can recover the system for $159.00 plus return shipping (within the USA) to you. Please let me know if you are interested and I'll give you further details.

Thank you,
