It sounds like your computer can?t read the boot sector on your hard drive which it needs to start up. The most likely cause is mechanical wear which usually starts gradually and gets worse over time. The computer ?system? can generally overcome these read errors through a series of read retries at first but as the problem progresses it becomes more difficult. When this retrying becomes more common users typically notice their computer making a ?clicking? noise. Mechanical hard drives failures not uncommon on laptops where power settings have the hard drive shut off after 5 or 10 minutes of inactivity. This is done to increase battery run-time; unfortunately this puts a lot of stress on the hard drive. My default settings for all my laptops is to not allow spin down (shutdown) while on A/C power and when on battery only to spindown after 30 minutes of inactivity. I would go into your BIOS setup (F1) and verify your hard drive is still defined and as long as you?re there take a look to make sure the date and time are still set correctly. If everything looks OK quit out of the BIOS, shut down and restart your laptop, several times if necessary. If you are lucky and this is the beginning of the read error cycle then eventually you will be able to start your PC. If you are successful immediately backup your data, collect up your restore CDs and install a new hard drive. If you have any other questions let us know what additional info you have. As always please don?t forget to rate this post.

Unfortunately this is not a Hard Drive issue. When the Laptop displays "0175:Bad CRC1,stop POST task" The PC just freezes and does not let you go anywhere else, neither the Bios or Setup. IBM's only solution is to replace the Mother Board. There are other solutions is you google it but all of which require an investment of between $70-100. All in all it is much better to just replace the board which can be found on eBay from anywhere between $30 to $70. Hope this helps and Good Luck!!

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!

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.
