Re: Helix 20CG won't wake from sleep mode

2016-08-19, 16:17 PM

I am very disappointed by this buggy device. Helix2 is the first thinkpad product I have, and I don't think I will choose thinkpad in the future. Since the time I bought helix2, I experienced tons of bug. In win8.1, the fingerprint sensor constantly stopped working, WIFI driver at that time was a disaster, and connected standby constantly has severe battery drain so that I have to manually hibernate the machine. In win10, the initial 10240 is already very buggy, coupled with buggy DPTF driver and makes the device unusable (e.g. screen doesn't rotate after resuming from sleep). I also have the experience of losing data because the machine cannot be woken up successfully. The keyboard dock also has tons of issues: the speaker driver is buggy and drains battery severely, and then I noticed severe battery wear after a short time of use, and then I found the keyboard will lose input (lenovo updated the keyboard firmware three times to make it work properly)

--------

Yep, that's why I suspect the graphics driver is the culprit. It also causes BSOD when the machine resume from hibernation sometimes

I finally get this device working properly now (which is after more than one year of buying this device).

I suggest you do a fresh install of windows 10 without lenovo foundation driver and thinkpad setting dependency, but hotkey utility (lenovo on screen display) is recommended to install

lenovo foundation driver and thinkpad setting dependency will cause weird issues, like severe battery drain during connected standby, this is confirmed on my machine 

Also I recommend to update important drivers to newest version, including intel serial IO (ver 1.1.253.0), fingerprint driver (4.8.207.1), WIFI driver(ver19.0.1.1),  DPTF driver(8.2.10900.330), and graphics driver (20.19.15.4483)

With this configuration and windows 10 14393, I experienced no issue during 2 weeks of usage (I indeed observed that 4474 might cause blank screen again (very rare), but didn't experience any in 4483 so far)

Good to know that a clean install for Windows 10 works for you.

I have not had time to do such a thing yet, but I plan to try it out.

This tablet currently just sits on the desk in my room while I use remote desktop from another thinkpad x220 tablet pc laptop.

Lenovo, if you read these forums ever, fix your firmware/driver issues on this device! god damnit!

I'm not looking forward to it but I may need to do the fresh windows 10 install.  Had problems again with 4474.  Installed 4483 today to see if that will do the trick, but I'm not betting on it.  Clean install without extra Lenovo software sounds like it may be what I need to do.  I hate trying to get everything back in place after something like that.

I feel everyone's pain on this issue.

 

I also have experienced numerous issues with my 2nd Gen. I think this is why Lenovo has stopped the lineage, and has gone with the X sereies ultrabooks.

 

Everything is okay as for now.  As for battery usage, yeah we should be getting 12 hours... I think that is mostly as a standby time. I yield around 3-4 hours on full use: about 1 hour on the tablet, then 3-2 on the tablet. I already bought fresh batteries, and still have a fresh ultrabook keyboard still in the box, all free of course when I had my warranty. I agree that a lot of the Lenovo proprietary apps and interfaces suck battery life.

 

I also got in a new hard drive. Samsung 950 PRO 512 GB, and it works great, my CPU seems to be bottlenecked now, but as long as it doesn't overheat.

Ok, took the plunge and clean installed.  Got all of the drivers up to the levels listed, except ent back to 4474 because I had a black screen issue after initial install on 4483.  Also could not find DPTF driver(8.2.10900.330). 

 

Boot is so much slower than it was before clean install.  Not sure what to do about that so will listen to suggestions.  We'll see how the black screen resume from sleep issue goes from here...

Fixed boot issues, changed wireless settings to disabled for magic packet, etc, turned off wifi when sleeping, and moved to 4483 again.  Boot is fast.  Resume from sleep is working (so far), and overall I am cautiously optomistic.  We'll see.

 

In case someone else clean installs and then gets the slow boot issues, turned off fast boot (defaut was on), booted, then turned it back on in power options.  Rebooted again and all is good.  Also, went back to password login instead of pin.  Not sure if that had anything to do with it or not.

In case you need latest DPTF driver:

I found this in DELL support site, and it works well on my machine

Re: Helix 20CG won't wake from sleep mode

Thanks for the driver.  Interestingly enough sleep mode resume now works fine with the rebuild and 4483 when I force it to sleep (power button) or when it goes to sleep after the specified time.  There is a slight pause occassionally, where the screen is clearly lit but stays lit as black for 10 seconds or so, then turns on with login prompt.  

 

The issue is when it goes to sleep after 'closing the lid'.  The screen comes on and I can log on, but the resolution is higher (everything is smaller), I can't get new apps to start or the start menu to function, and the screen clicks with mouse, pen, or touch does not consistenly work.  I need to reboot to get out of that.  Reproducable.  However, I can avoid that 'sleep' mode by using the buttons to put it to sleep.

 

Much better overall.  Thanks for the advice.

Maybe you can try the new DPTF and see how it goes. I've also experienced weird resolution issue before, but haven't seen it for recent several weeks using the configuration I mentioned. Also, the wake up pause also occurs occasionally on my helix. I guess it might be an OS issue, as it exists since win10 10240, and I experienced similar issue on my desktop with NVIDIA graphics card.

Long time since I wrote to this forum, but still as disapointed as before. Still having problems with my 14393 build, but as before, the problem always increases after installing Citrix GoToMeeting.

 

Also, as some in this thread also complains about the spleep energy drain, I noticed that the sleep mode energy drain was as expected some ime close the a OS refresh, but after just a day or so, the device starts to drain to much energy when in sleep mode

 

The driver causing the problem for me is:

  • USB xHCI Compliant Host Controller (\_SB.PCI0.XHCI) Fx Device
  • Intel(R) HD Graphics 5300 (\_SB.PCI0.VID) Fx Device
  • Realtek USB Audio (USB\VID_0BDA&PID_4000&REV_0002&MI_00)
  • Sierra Wireless GNSS Sensor EM7345 4G LTE (USB\VID_1199&PID_A001&REV_1729&MI_02)

We have about ~2'000 of these devices currently running Windows 8, but we can't deploy windows 10 on them until this is fixed. Time for Lenovo to shape up in this!!!
