Random hibernation/power off, faulty lid sensor?

Good day to you all, my fellow hardware repair enthusiasts. I have stumbled upon a very annoying issue with my notebook and I am wondering if somebody could provide me with much needed help.

Yesterday my GL702VM started to hibernate randomly without any apparent reasons. Before hibernation a default Windows “Locking” screen with a progress indicator spinner appears for half a second. After that it won’t start properly and it will turn off immediately after turning on (it turns on, I can hear the HDD and fans starting to spin and then it immediately turns off, the whole process takes less then a second). By fiddling around with it I found out the following:

The notebook can power back on properly and boot to Windows if I leave the notebook powered off for a lengthy period of time (couple of hours), but after an hour or two the issue comes back unchanged. Could this be the indication, that the problem is caused by overheating and not the sensor?

I managed to start the notebook and boot to Windows by pressing the power button and then immediately closing the lid until it boots. Then, after opening the lid I can log in and use the notebook for 20-30 minutes, before it hibernates again. I am currently conducting a test to see, if the issue persists if I leave it running with closed lid and “Lid close action” set to ‘nothing’ on both plugged in and battery. So far it has been running for more then two hours without hibernating.

Weirdly, it seems to ignore the power settings for when the lid is closed, as this behavior persist even when “Lid close action” is set to ‘nothing’ on both battery and plugged in. Probable indication that it could be something else other than lid sensor or is there a possibility, that the sensor somehow overrides the default Windows functionality? Also, the screen turns on and off normally when opening and closing the lid which confuses me greatly.

If it hibernates and I manage to boot it properly on the first try, I can confirm, that it is in fact hibernating and not powering off, as I am able to log in back into my previous session, with all applications still open, but if it powers down before booting and I manage to boot it after that it boots basically form scratch with everything that was open gone, so it is extremely unlikely that there is a problem with the power supply, motherboard power circuitry or the battery.

There is also (maybe) unrelated issue with weird malfunctioning columns of pixels on the display. For some time now, there has been a single column of weird looking pixels (not dead, just displaying wrong colors) at the left side of the screen (right around the left lid hinge), which randomly appears and disappears. Right before the hibernating issue started to manifest itself, the column became quite visible, about 10-20px width, but then most of them slowly disappeared and just a single line of pixels that still comes and goes randomly remained this way. Maybe this points out to the issue being with the GPU and not the sensor? Am I right to assume, that in the case of the dying GPU, it would require a full motherboard replacement, as the GPU is probably soldered to the motherboard without possible hope for an independent replacement?

It would be great if someone could point me to the right direction regarding the operation of the lid sensor in GL702VM, as I have been unable to find any relevant information so far. I am mostly interested in a way of completely disabling the lid sensor to confirm that it is in fact the culprit. The Windows Power Settings didn’t do the trick, so I am interested in a way to disable it at the hardware level by unplugging and/or removing it, as there is no BIOS setting, related to the sensor behavior apart from the ability to wake PC from sleep when lid is opened, disabling/enabling which didn’t have any effect.

So far I was unable to identify the location of the sensor and the corresponding magnets on the motherboard by dismantling the case and visually inspecting it, but I found the two magnets on what appears to be the left and right speaker modules and I am wondering if they have something to do with the issue. Also, if my suspicion about malfunctioning sensor confirms, I would like to know if and how it is possible to replace or repair the sensor.

To the best of my knowledge, the faulty sensor is the most possible explanation but maybe there is some alternative theories out there?

Hi @leontheweirdo ,

Depending on how often this occurs, try starting the laptop in safe mode and check if it still occurs, just in case it is something else.

Sleep/hibernation modes shouldn't happen in safe mode

How long has it been happening.?

Have you got any restore points set to a time before the problem started to check if you can restore the PC to that point in time and check if it is still happening?

You won't lose your data only have to re-install any new updates or programs installed since that time.

You might find that you don't have a restore point as for some reason it is turned off in Win 10 unless you enable it.

With regards to the intermittent pixel problem ,it may be a loose video cable connection or perhaps a damaged cable where it passes through the lid hinge. Worst case is if it is a panel problem i.e. a loose connection in the panel itself

Try slowly moving the lid back and forth or apply some pressure to the hinge (not sure which one, left or right)to see if you can make it happen.

Just some thoughts.

Hi @jayeff, thank you for your response.

The issue started the day before the original post.

I tried starting the laptop in safe mode and the issue still manifested itself after a couple of minutes.

Unfortunately, I forgot to set up any restore points as I was under the impression that it supposed to be enable by default as it was in Windows 7 if I remember correctly.

You were right about the lose connection in the hinge, applying a little pressure to the right lid hinge seems to fix the problem.

I think the issue is getting worse, as now the laptop doesn't even go to hibernation anymore, but turns off completely, but maybe it has something to do with the settings I changed.

I'm having the exact same problem. I know my internal battery is bad and has been for some time now, but never had problems with the power cord attached. It boots up the says hibernating after a few seconds. Did you figure it out?

@leontheweirdo ,

OK, so it appears to be not a "sleep/hibernation problem but maybe then it's a power problem

Not sure if I missed it but does this happen when the charger is connected and switched on?

If not or even if so, try creating a Win 10 battery report and check the results in case it is a battery problem.

Try downloading and running this free memory test program and check if it happens while running the program. The idea here is not that it is testing the memory per se, but that it is testing the hardware without the OS software operating, as it is a standalone program that doesn’t rely on Windows to run. Either that or just get into BIOS and leave it for a while and see what happens. If nothing then its’ looking like an Windows problem or a compatibility problem. Was there an OS update done on the laptop just before the problem started? (Windows Settings > Update and Security > Windows Update > Update History)

Again these are only trying to eliminate possible reasons for the problem.

Back on the pixel problem, here’s an image taken from this teardown video of your laptop that shows the cable passing out of the right hinge.

(click on image to enlarge for better viewing)

If you decide to follow this up and check if the cable is damaged and find that it is, rather than just being loose, here’s a link to a supplier of parts for the laptop.

It is handy because you can find the Asus part number for whatever part you need for the laptop and then search online using the Asus part number only, to get results for suppliers that suit you, so at least you know that it should be the correct one.

Click on the “cable” checkbox on the left side to view all the cable parts. There are 6 EDP cables for the laptop. It must depend on what the specs are for the panel etc as to which one is the right one for your particular model variant. Don’t be misled when it say GL702 VT as the cables are the same for each model VI, VM. VS, VT. Hopefully it may be marked on the cable so that you can verify and the pincount should help as well.

With the restore point, once you have set it it does work OK, but twice over the last two years it had been turned off in my PC after a “feature” update was installed and I had to turn it on again. Been OK after the last couple but has made me check after every major update just in case. It is too handy as a backstop not to have it working.

Not certain that they use lid magnets anymore in laptops. I know with some (don’t know about Asus though) they use a sensor (non magnetic) on the power button board that detects if the lid is shut. This is for laptops that had the power button on the top at the back of the keyboard near the screen so there may be something similar going on with yours. You could try running a magnet along the top of the keyboard under the screen to see if this turns the display on or off to see if it is magnetically switched or not. Just a thought..
