M72e Desktop (Tiny) 4004 sleep mode issue (not waking!) in Windows 10

Hi there,

 

I work in IT for 19 years now but I only have a limited experience with LENOVO ThinkCentre product's line. I just got (for free) an old ThinkCentre M72e (Type 4004) tiny desktop that were coming from the factory with Windows 8 Professional, then was downgraded from the factory to Windows 7 Professionnal (using Microsoft downgrade rights) because the company's software that they use where not compatible at this time with W8. Somewhere around 2015-16, the computer automatically upgraded to Windows 10 Profesionnal (during the free upgrade period), but the people uninstalled it back to W7 since the company's software was still incompatible with W10. End of the scenario.

 

When receiving the M72e, I first replaced the factory HDD with a very fast SSD I already had, then I installed W10Pro using a generic USB thumb drive and everything went fine, the computer already had his digital licence, so this went perfectly smooth. Since this computer is not that much old, all drivers and peripherals installed automatically with Windows Update. Then, I ran the latest BIOS update available for this computer (F4KT61A - 24 Jul 2018) and update went good. So I thought that the computer was up and running and ready to be given (for free) to my mother in law who have a 12 years old computer that are still W7. So I left the M72e running on my desk during a day, then I noticed that when the computer goes to SLEEP mode, it never wake up. If I press any key to wake it up, the power LED stop blinking, the WiFi LED turns ON also, but the computer just do nothing. No image, no signal. I noticed that this is not only the display this is not waking up, since I have a unattended access TeamViewer running and it shows that the computer is OFFLINE.

 

I searched A LOT on Google about this issue and found several threads not specifically for the M72e, but here's what I tried so far (found on discussion forums) :

 

- Disabled EFI/GPT boot (default) and reinstalled W10Pro in BIOS/MBR mode

- Downgraded the Intel HD Graphics driver to the older version (2015) on LENOVO website instead of the Windows Update version (2017)

- Upgraded the Intel HD Graphics driver to the latest version from INTEL website (MAY 2019)

- Installed all drivers provided for W10 from LENOVO website (chipset, sound, etc) instead of the Windows Update provided version, who are usually older than current version

- Resetted BIOS settings to default (except for EFI boot disable)

 

This is pretty much it... I am a bit out of idea now. Any clues for me? Thank you! :-)

Re: M72e Desktop (Tiny) 4004 sleep mode issue (not waking!) in Windows 10

By the way... I just had the idea to put back the old factory hard drive still with Windows 7 backup into the computer to see if the sleep mode still works fine and to exclude any (new) hardware issue or a new issue related with latest BIOS and sleep works perfectly with the old W7 hard drive. By the way (2) I had to turn back ON EFI support in BIOS because W7 is actualy installed in EFI mode.

 

So the issue is definitely and exclusively related to Windows 10.

Does hibernate work correctly?  There are some known sleep issues around this generation ThinkCentre, which processor does it have?

I just tested it (it was not enabled yet) and the hibernate work flawlessly. My processor is an Intel i5 3470T @ 2.90 Ghz

By the way (3), I also did a new test earlier this morning. After putting back the W7 HDD into the computer, I ran the Windows 10 update over Windows 7. Usually this lead to a different behavior than a clean W10 install, since the update process keeps some old W7 drivers/apps... but the result is that the "updated" Windows 10 also DON'T wake up from sleep mode.

There are Lenovo models, released on the cusp of being Win 10 capable, such as the M72e, with both Sandy Bridge and Ivy Bridge processors, and a Chipset that supported both.  That were or became problematic (with later feature releases) with waking from Win 10 sleep mode.  A clear cause and solution has not been identified.  It appears you have done all that is possible, and I don't have any suggestions other than, worst case, to use Hibernate mode.

Try installing and running Lenovo System Update, it will look for specific drivers for your model. I used it in all my tinies with no issues, although I rarely use the sleep mode to be honest.

 

I'm not sure if this will help but I think is worth trying...

 

I just clean installed Win10 on my new(old) M72e Tiny few days ago, but I haven't tested sleep mode, I'll see if I can do that during this WE.

 

Regards...

Re: M72e Desktop (Tiny) 4004 sleep mode issue (not waking!) in Windows 10

I am gonna give a try to Lenovo Update tommorow to see if anything prompt. I don't have really high expectation however because I already checked most of drivers manually and the drivers that are automatically installed by Windows Update are more up to date that the ones provided on Lenove website.

 

I don't know by heart which chipset are fully supported by Windows 10, but I am a little bit disapointed since this computer is only around 6 years old and I usually work with HP or Apple computers and I have several very old HP business's line computers at home, such as a DC5000 and a few DC6300 that work perfectly with Windows 10 and who are much much older that this Lenovo M72e. Can you believe that the DC5000 were coming from factory with VISTA, but were updated to W7 then to W10 flawlessly. The DC6300 came with W7 from factory and also updated flawlessly to W10. Smiley Sad

Well, as expected, the Lenovo Update didn't bring any fix to my sleep issue. Yes, the updater found some driver such as a chipset driver (may be promissing) and a LAN driver, but after installing both, the computer still don't wake up! Smiley Sad Smiley Sad Smiley Sad

I didn't have time to check what my own M72e does. I guess it won't be different though, but I'll see if I can give it a try and report it here.
