It has on infrequent occasions taken up shutting itself off. I did the normal thing and tried to ignore it. After all, it always started up right away afterwards.
Sunday was different - no pretty lighted button lighting. All was darkness.
I do have an older computer also but they are not synchronized. I could still work on my surveys and stuff. But I could not access my Verizon email accounts.
Turns out it was the power supply. Got it in Monday late. Got it back today (Wednesday). Also asked them to check the machine out completely and they found some viruses - malware and ad ware. Very frustrating because I am almost religious in my zeal to keep up to date antivirus software running.
All-in-all it was a not so good start to the week.
