Z61m - Error 0188

[TerryB]

Started getting this error after a bios update. When checking the bios, the Serial Number field is now blank. I've read elsewhere, that this can be fixed by using the Hardware Maintenance Disk. I believe the file I need is i7tm23us.exe, but so far searching the web has failed to find anything. Does anyone have this file please, and can email it to me.

The HMD is a proprietary Lenovo Maintenance file that is given out to partner repair centers. We can't allow discussion of where to get it on this forum.
