Studio 1458 i7 upgrade = no wake from sleep

I've upgraded three Studio 1458's with i7-720 or i7-820QM CPU's. All had i3- or i5 to begin with, and all have the ATI/AMD discrete graphics (obviously).

Problem is, once the i7 is installed, the Studio 1458 won't wake from sleep. When asleep, it will start the process of waking up, but no display, and typically the fans are running fast. If I hold the power button, it will turn off, but won't turn back on properly. It powers on, but no screen and fans running fast. If I remove the battery, and reinsert, it powers on correctly and boots up normally (apart from the Windows startup menu to "Start Windows normally").

Ideas??? This model is sold with i7-720QM and i7-820QM CPU's, so I can't figure out why all three are doing this.

Thanks for any help or ideas.

 

Does it do it with the original processors installed? Do you have ES/QS chips?

 

I do not think the sleep issue happened with the original CPU's because the users didn't notice that sleep didn't resume until after I handed them their upgraded notebooks back. Personally, I don't use sleep mode, but I did confirm that even my own does not resume from sleep.

And, no, they are not ES or QS chips. They are normal spec'd chips.

Thanks.

 

Is there perhaps a setting in the BIOS or did you mess with Windows sleep settings? I also don't use sleep, and I don't think it is a problem with the processors, as 3 in a row defective is highly unlikely.

 

Yes, tried all the normal stuff. Nothing in the BIOS. It worked before i7, but hangs on resume after i7. Nothing else changed. But, looked at advanced power settings, and still, no joy.

 

Reset BIOS to default settings and reinstall Intel chipset driver. Try to boot from different HDD with new windows partition.
Try to upgrade BIOS to newest version.

 

Already at the latest BIOS version. Reset BIOS to default did not fix. Latest Intel chipset said already up-to-date.

The odd thing is the notebooks wake from sleep just fine with the i3 and i5. Just putting in an i7 should not affect it, nor all three notebooks!

 

i7 has no video chip integrated, maybe i3/i5 has different mainboard and cannot be upgraded to i7 because if you cannot see the windows but pc wakes there is some video issue. Try external display and see what happens. And update video drivers from AMD website. I have upgraded my Lenovo from i3-350m to i7-720QM and had no issues, everything works.

1458 had 3 different ATI graphic cards 4530, 540v, 5450. Only 5450 where compatible with i7 cpu.

 

While it does wake (only when pushing the power button), from what I can tell, it's essentially non-responsive. Even though there isn't any display, the fans are on, and then in about 30 seconds, the fans come on full blast.

If I hold the power button to turn off, it won't turn back on normally...it just turns on again with the fans stuck on full blast. I have to remove the battery to "reset" the PC into allowing it to power on and boot normally.

Weird stuff.

 

I also have the same issue as OP.

Its really annoying to not be able to wake up from sleep or hibernate. If my computer goes to sleep or hibernate when I try to wake it up with the power button, the computer starts to wake up but the screen is black and after a few seconds the fans start to spin full speed. If I hold down the power button to shut down the computer it will shut down, but when I try to turn it back on the screen is black and the fans start to spin at full speed. The only way to get out of this is to pull out the battery and then hit the power button and the computer starts up and I get the option to start in safe mode.

I have a dell Studio 1458 that I purchased from Dell with the i7 Q740 @ 1.73GHz. My video card is the Radeon HD 5450.

I have installed the latest BIOS and drivers from support.dell.com/support/downloads/

I have not found a solution and this is very annoying. My last resort is to image the computer and reinstall windows to see if that makes a difference

 

One solution that I discovered (but have not tested) is if you install Windows with the SATA channel for the HDD in ATA mode instead of AHCI. It is my understanding that the problem goes away.

Unfortunately, it requires reloading Windows (unless someone knows how to convert without reinstalling).

Why it does this would be nice to know. An i5 does NOT have this issue, but an i7 does? Weird.

 

Thanks for the tip. I will try and set my HDD from AHCI to ATA. If this requires a re-installation of windows I think I can live without sleep mode.

EDIT:

I just wanted to post an update on my findings trying to change my HDD from AHCIto ATA mode. I googled around for a solution and the most common method of doing this is changing 3 values in the registry and then switching from AHCI to ATA mode in BIOS. I followed those instructions, which caused A BSOD every time I switched from AHCI to ATA in the BIOS. I gave up for a few weeks and today I ran across this thread in another forum and I was able to make the switch from AHCI to ATA follows the instructions here http://www.vistax64.com/general-discussion/271218-switch-ahci-ide-tutorial-howto.html

I am now able to wake up from hibernation and sleep mode without any problems.

Thank you very much lancorp for providing a solution that finally worked.

 

My laptop started acting up again and not waking up from sleep or hibernation. I switched back the SATA channel for the HDD to AHCI.

The only way for the laptop to sleep and wake up is to let the battery run down. When I plug in the power cord to the laptop I am prompted to press F1 to continue and then I have the option to resume.

I would really like to be able to manually set the computer to sleep. I am out of warranty and if its a hardware issue I'll learn to live without the laptop sleeping.

 

are those chips supported in that configuration? IE did Dell offer them as options on the machines? BIOS may not have the proper routines to bring the system out of sleep for those chips.

 

I customized my laptop through Dell and I have not replaced any of the hardware.
