Does any know how to fix a CRC1 error on an IBM laptop? pls help.


if you get this for a CD/DVD disc, your disc is bad...if you get this error on your hard drive, it means your drive is failing.

try to backup your data if possible and you will need to replace and reinstall all software. if the data is critical I recommend going with Drive Savers or another reputable recovery service.

ERROR 0175: Bad CRC1, stop POST task message Been using my IBM a30 laptop for some months but was surprised to get this error when i tried putting it on this message pops up ERROR 0175:BAD CRC1 STOP POST...


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 notbook. how will i solve "bad crc1, stop post task. with an error code 0175?


The POST error code 0175 refers to a CRC (cyclic redundancy check) reading from the EEPROM chip, that data is corrupted, most likely a faulty EEPROM chip. This is a motherboard problem and cannot be fixed except by a motherboard replacement. This is an old laptop and would not be worth fixing, I suggest you put your money towards a new laptop.
You can remove the hard drive and put it into an USB hard drive adapter case and use it as an external USB hard drive.

This problem you may not be able to fix. There are a couple of things you can try.
1st Keep on rebooting your laptop until this error goes away.
2nd Replace the BIOS battery, it maybe nearly worn out. After replacement you need to go into the BIOS setting to set the Date & Time.
