E6400 bluescreen code 9f on sleep/shutdown

Hi folks,

Just got a new E6400 and even before VISTA had fully loaded 1st time, it had bluescreened and showed a minidump with errorcode 9F = DRIVER_POWER_STATE_FAILURE.

Error occurs very often when going to sleep mode, and sometimes when doing reboot or shutdown. Computer then hangs for 5-10-15 minutes before rebooting and showing the VISTA error report. Now, 2 days after 1st power on, I've had probably 10 BSOD's during sleep / restart / poweroff operations.

Searching the net for similar problems made me test the following:
a) Have experimented with disabling "allow powersave" for wifi and 3G card, made no difference.
b) Have tried downgrading webcam driver, no difference.
c) Have tried going from BIOS SATA mode IRRT to AHCI, no difference.
d) Wanted to test XP SP3, but it locked during CD-boot when XPSP3-CD shows "Setup is inspecting your computer's hardware configuration". Tried AHCI and ATA compatibility mode, same result, locks at the same inspecting-message!.


The E6400 config is Vista 32bit business, P9500, 4GB RAM, Intel 5300 wifi, Dell 5530 3G-card, Dell 370 bluetooth, 160GB HDD, 1440x900 LED backlit, webcam.

Anyone had similar problems, or tip for how to solve this problem?

Thanx for your time,

all the best from Gard

 

If I had to take a stab in the dark, I'd say it was a memory issue. I'd try running memtest or something and seeing if it turns up any errors; if not, it could be a driver problem, but since you can't even get into XP setup, I'd vote against that. And then it's possible that you could have a much more serious problem and should probably send it back to Dell...

 

Problem solved! (?)

a) Change in BIOS to SATA AHCI mode instead of IRRT
b) Delete all partitions
c) Full reinstall of VISTA from supplied Reinstallation-DVD.
d) Only install required drivers, especially NOT the latest Intel Storage Matrix driver (I also had the DPC latency problem before VISTA reinstall...)

Now the computer sleeps+reboots+shutdowns when it is supposed to do so, and no bluescreen crash so far.

Hope it lasts...
