Thinkpad A21m 2628 G7u BIOS/Video Shadowed Error 0175: Bad CRC1 Stop POST Task

Having read numerous requests on this Thinkpad failure, there appears to be a common problem around the world with this model. My laptop shut down suddenly and when I turned it back on it does not move beyond the the system test screen. Along with two beeps. I have the 'on' light.

I downloaded the BIOS (spsdKx36) from the IBM site, placed it on a disk
and attempted to update the BIOS. Nothing. It displays preparing boot device list, after I pressed F12.

Is it possible there is a virus that is affecting/altering critial system components? Or, just a bad system board that IBM would like to replace?

Would using Bootdisk.com download to boot the machine start it up again?
If so, which program would I download? Windows NT is the operating system.

Thank you for your assistance. Sandra G sandragerdin@cs.com

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.
