Hi, I have a Toshiba Tecra M4 Tablet PC that is about 2 years old. 1 year ago, the machine froze during use requiring a hard reset. When it was reset it failed to post (all I got was a black screen). After several hard resets from this state, I got the machine to restart. Now, after the machine runs for a period of time (sometimes 5 minutes, sometimes 25 minutes), it freezes again and goes into the failure at POST. Now, sometimes it takes 30-40 hard resets at the start to get it to POST and boot - but when it does the machine runs perfectly until it freezes. If, when the machine is running properly, I do a normal shutdown, the startup is uneventful. It seems that a hard reset is what causes the problem at startup. I have updated the BIOS to the latest version. I have tried disconnecting the CMOS battery, taking out the laptop battery, etc in an effort to reset the CMOS - nothing works. Any suggestions? I feel like this is a (relativley) minor problem, as the rest of the machine works 100%. What I am looking for is a method to reset the BIOS right after I do a hard reset. I think this will clear whatever issue is preventing the POST. Thanks,
