It really may be better to train your laptop battery to run down!
I unplugged the laptop, waited for the storm to pass, and replugged it. After a wait of one minute, it seemed that the Dell machine would recognize it was active but asleep. It brought up a warning screen, said resume windows. It took about one minute for Windows to resume, with the user accounts locked. After unlocking, the machine worked normally.
It seems as though the firmware knows how long it has been powered down. You must pull power and leave if off for a specified time, as is the case with cable modems sometimes. Car batteries and starters sometimes work this way.
I guess I’m in the habit of using the house current too much. The battery lasts about two hours before running out. It probably does better if train it and let it run down more often.
