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!

Bad CRC1, stop POST task. The EEPROM checksum is not correct


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.

IBM Laptop A22e Display an error 0175


The CRC error (POST = power on startup test) on boot up refers to the BIOS settings. This could be cause by a near flat BIOS battery and it needs to be replaces. If it is not the battery you need go to the BIOS to correct any faulty settings.
