Need help with laptop randomly switching off during high-end gaming sessions. Runs fine under normal workloads and laptop is not overheating during intense gaming(80c max). Bios has been updated to latest v1.19 (model G3-572). Had opened recently for repaste(liquid ultra-II) but I have made sure that all screws are securely fastened and the ram cover pushes the battery switch. Laptop runs fine on battery but loses power while connected to mains and running CPU/GPU intensive apps after 5-10 mins,then laptop does not restart and after pressing the power switch only keyboard powers on for 5-10 seconds and it cuts out power again: this loops for about 2-3 times after which screen finally turns on to display the predator logo and then laptop boots and works as expected...until it happens again.Event ID 41 is generated at startup. I use MSI afterburner to monitor temps while gaming so pretty sure its well within the temperature threshold. Is there anything else that could be causing this issue ? I suspect its related to power delivery. Have already tried resetting the battery..Pretty sure I cant get a warranty repair done after a repaste.
Also an observation: The same thing happened when I flashed Bios 1.19, fans at full speed during the flashing process and then laptop lost power unexpectedly. However its booting into the Bios without any issues.

    power drain: Just check the back of the unit, you can find a pin hole , unplug the charger and turn off the unit. now put a paper clip in the small pin 
    hole and press and hold it for 30 sec.

    BIOS default: After power drain is done, power on the u nit, but as soon as you power on the unit keep pressing the F2 key so that it take you to BIOS 
    page. Press F9 and press Enter than press F10 and press Enter. the unit will restart

    Try to run benchmarks like Prime95 to find out if it's a power issue (maybe the power supply is defective) or CPU / RAM / Graphic card issue.

    Don't panic! This is NORMAL.
    Your power supply supplies max of either 135 watts or 180 watts based on the region you are in. Your laptop pulls in more than that when working under peak loads. This gap in power needed against what's being supplied is taken from battery. This is called hybrid utilization of power.

    For example... just the 7700HQ processor can pull up to 56 watts of power when under peak loads, and then what other components like mother board, graphics processor and screen take... all this easily surpasses the 180 watts the charger supplies.

    If the psu isn't feeding it enough power shouldn't it be draining the battery ? Laptop turns off at 100% battery ! Is there any way I can check the power consumption of the laptop ?

    Not all the time... only when in peak loads. Example, 7700 drains at about 10-20 watts on average, peaking at 56. It won't go to peaks unless it is pushed to.
    Laptop turning off at 100% battery is a different issue. When in windows, open power settings and disable fast startup option - this does more harm than good in most cases.
    Install a small program called battery bar - it shows precise information of charge/discharge rates on the fly (you could also use powercfg, but i prefer this for simplicity). You could always freeware programs like hardware monitor and such.

  • I don't think it's a power draw issue, and I wouldn't consider it "normal" if it was.

    Are you using any undervolting software?
    I know throttlestops speed step if set too high for a CPU intensive game gives the symptoms your experiencing and temps would never have gone too high. 
    (Example: PUBG cant handle more then 110 SSEPP)
    Are you undervolting your GPU?
    Any tweaks worth mentioning?

    Yes ! I'm using throttlestop and more or less all settings from this video : 
    https://youtu.be/F1rs92CiYxU
    but I deleted throttlestop and re-tested it again and still giving me the same issue.. Is there any chance the CPU didn't revert to stock after deleting?

    Ah.. did you know I made that video ;)

    I actually made a second one you might want to check out called Throttlestop Remix, the latest Windows update made that video not quite work with every game.
    Basically the new sleep states for Realtek conflict with those settings for some games which cause a trigger effect that freezes the GPU.. its pretty annoying. 

    Anyways check out the updated one here:

    https://youtu.be/N3v3o21M8gg

    The short of it is you want to lessen your undervolt and speed shift epp when playing those high cpu demanding games. I actually have a seperate throttlestop profile made for that.
    For example: PUBG will freeze on my laptop, but if I set undervolt for cpu core/cache to -0.123 and my speed shift epp to 110 it works fine. The values vary between laptops but a good value to start at would be -0.120 (for i7-7700HQ) and speed shift at 110. You can also try removing the undervolt for the Intel gpu.

    Here is an upload to a config file I created that you can try instead.

    https://drive.google.com/file/d/1iMUWuWHPrgNCHlhShkInf4nR_fDL7ZWZ/view

    As for removing Throttlestop, you need to delete the config file in throttlestop's folder then shut down (not reboot) to completely remove its effects.

    Wow, that was unexpected  :) So I did everything from your video except I had a core voltage offset of -0.110..Its no wonder the repair guys couldn't pick up any hardware faults..so basically, if I reset the CPU I shouldn't in theory be running into the GPU freeze issue?  Is that what's been causing the shutdowns ? Shouldn't a gpu freeze be giving me some sort of BSOD ? Because I'm still having these shutdowns after completely deleting the throttlestop folder. Everytime the PC restarts,the date and time is reset, suggesting that the CMOS battery circuit was cut off(probably). Is there anyway the CPU settings could've persisted even after deleting throttlestop ? I'm yet to try all settings from the throttlestop remix video, will try those once I collect the machine back from the repair guys today. is there anything I could've done wrong? Basically I haven't touched the GPU clocks or voltages.

    Yes throttlestop's values should be completely removed once you delete the config file in throttlestop's folder then *shut down* (not restart/reboot).
    If the problem persists after doing this then I suspect another issue is causing it.

    The GPU freeze can be cause from speed shift yes, as I mentioned it causes the Realtek driver to not wake up from a sleep state which in turn freezes the Nvidia HD audio.

    So try installing the Realtek driver from here:

    https://www.acer.com/ac/en/US/content/drivers

    Then download this program and screen shot the info here.

    https://www.cpuid.com/softwares/hwmonitor.html

    If your time/date is being reset it could be a CMOS issue for sure.

    Have you tried the pinhole reset on the bottom of your laptop to power cycle?
    If you have it might be a good idea to send it to Acer to fix/replace the CMOS which could end up being a mother board replacement or a battery replacement.

    Worst case scenario is error 41 being a GPU hardware failure code in which case a motherboard replacement would also be required. There was a batch of faulty Nvidia chips released a while back and it unfortunately effected thousands of laptops of many brands.
