Since installing Windows 8 (the problem didn't happen on Windows 7), my laptop will lock up:

  • All apps will gradually stop responding when interacted with, for a minute or so, and then everything starts working again.

The problem normally happens soon after I log in.

Looking at Task Manager I see this during the lock-up:

Active time == 100%. Disk Transfer rate == 0.

The disk is an SSD Crucial M4 CT256M4SSD2

Post the S.M.A.R.T data for the drive. – Ramhound Apr 19 '13 at 11:23
I just saw another question that recommended updating the firmware on the SSD (for a different sounding problem). I will try that. – mackenir Apr 19 '13 at 12:30
Hmm. Assuming I have a Crucial M4 2.5" SSD, the Windows 8 updater doesn't work (it doesn't list any drives). (from here: – mackenir Apr 19 '13 at 12:48
It might be good if you verify what hardware you have exactly. We don't know what hardware you have. Have you tried the manual boot method? The instructions show how you can verify the drives Hardware ids information. – Ramhound Apr 19 '13 at 12:52
OK, I've successfully updated the BIOS to the latest version using the bootable ISO instead of the utility. Fingers crossed this fixes the problem... – mackenir Apr 19 '13 at 13:44


sound like you run the HDD in the slow old IDE mode. Use AHCI instead. Install the latest AHCI drivers, go to the BIOS/UEFI and change the SATA mode from IDE to AHCI.

Oh, thanks for this advice - I'll give this a try. – mackenir Apr 20 '13 at 15:04
