Hi there,
For a long time already, I've been noticing Intel SSD X25-M 120 GB (and possibly also 320) has got incorrect 'power on' count hours in S.M.A.R.T. report. I'm running my Montevina based ThinkPads (one X25-M, the second with 320) for many hours each day, yet the count kept suspiciously low.
The other day I had spare time and run following experiment:
-took a note about power on count at morning and let my machine run for all day and night long (no sleep/hibernation mode)
-took a note again next morningI've done this twice and records are following:
-first morning: 1144 hours
-second morning: 1144 hours-third morning: 1145 hours(see attached screenshots)
Obviously 1 of its "hour" is longer than regular day.

According to your information (see https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=18455 https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=18455 ), my drive has got latest firmware.
Thank you,

Thank you for posting.
DIPM is indeed related to Power-On Hours Count:
"The raw value reports the cumulative number of power-on hours over the life of the device.
The On/Off status of the Device Initiated Power Management (DIPM) feature will affect the number of hours reported.

Thank you for the feedback and detailed step by step guide.

What is Intel's advice regarding enabling/disabling DIPM on a laptop computer?

Hi mutex7,
I can't speak for Intel, but from Intel's document 325152 State Drive 320 Series, Product Specification, March 2011 the drive's idle power consumption Idle: 100 mW (TYP) is mentioned explicitly with DIMP enabled.
In Windows it seems (see my comment above) that by default mobile platforms has got DIMP enabled as opposed to disabled on desktop platforms and that this is levered by Microsoft, not by Intel (certainly, the drive must be DIMP capable though).
Cheers,
k.
