227. Windows 7 - Post 217 (Power Mgt) Update

I finally decided to check with Dell about the problem at Post 217 which occurred 3 times so far since 1/6/2010. I decided to avoid the verbal struggle with the overseas 1st line of support and decided to try the Online Chat that I liked in the past. Well, not to get off the subject, but of course just getting to Chat was another problem. I could not get to it via the Dell Website. However, when I brought up Dell Support program on the PC and invoked it from there all was good. Now, let me move on to Post 217. 1st Line was of course snowed by the problem and details I gave them and simply, and IMMEDIATELY, told me to send it into the repair depot. Oh Boy. Motherboard problem he said. Yet, the problem occurs across multiple vendor machines? "Well, I'll send you an A/C adapter too to try!" In other words, he never heard of this problem and had no clue how to provide diagnosis support to isolate the cause. Anyway, I replaced my A/C power adapter yesterday and will see if it was the cause. BIOS is current, so that's out.
