According to Intel SSD Toolbox, the (0C) Power Cycle Count on my Intel 520 480 GB is 5419. I've had the drive for about 6 weeks, and it seems to be going up by nearly 1000 per week. The computer is not actually restarting 140 times per day. A normal reboot increments the counter by one. I've seen the other reports of high Power-on Hours Count and of the Unexpected Power Loss and Unsafe Shutdown Count incrementing with each Power Cycle Count, and I'm having those same issues, but I haven't seen anyone report unusually high Power Cycle Count.
Power-on Hours Count = 895626 (Normalized 0)
Power Cycle Count = 5419 (Normalized 95, this value is going down by 1 per week)
Unexpected Power Loss = 5418 (Normalized 100)
Unsafe Shutdown Count = 5418 (Normalized 100)
Everything else looks normal, and the drive is performing normally. I called tech support and they offered to cross-ship a replacement for $25 non-refundable. I'm inclined to do that. Has anyone else had the problem with a high Power Cycle Count? And if so, was the issue with the drive or was it with a different system component like the motherboard, power supply, or maybe even driver issues with sleep/standby?
OS = Windows 7 Ultimate x64
Motherboard = DX79TO
CPU = Intel Core i7 3930K
UPS = CyberPower 1500PFCLCD with no power events listed
I found the problem, and it was not the SSD drive.
I spent some time watching the computer after it went to sleep, and I saw that it was actually frequently waking up and going back to sleep. I finally found the cause. The network adapter was configured as shown in the screenshot below. I fixed the problem by enabling the "Only allow a magic packet to wake the computer" option (or I could have disabled "Allow this device to wake the computer"). Only two things wake up the computer now: 1) me, 2) scheduled tasks like the nightly backup.
