Model: Acer Aspire E7-774G
OS: Windows 10 64bit

This is not my laptop but I am trying to fix it for someone. I have read through plenty of posts and I have tried many things to fix this issue and I don't know what else to try.

The laptop will not turn on when it is not plugged into the charger and will turn off immediately when unplugged. There is some damage from the laptop overheating a while ago near the back left on the bottom of the laptop (back right if it is face down) so I assume the battery was fried. I ordered a new battery (same as OE) and installed it and the issue was not fixed. I then did some more reading and tried: 
- Power resets (through the small pin hole on the back/bottom / holding it for 30-45 seconds and leaving it for 5 min before turning on)
- Checking the power interrupt button (I placed some tape near on the part that should press it down to make sure it's getting pressed)
- BIOS update from v1.12 to v1.27  (ZAA2)
- Checking some power saving settings (Didn't find anything that looked like it should be changed)
- Deleting/uninstalling the battery/AC drivers and rebooting the laptop

I think that is all the things I have tried if I remember correctly, if there is any other info I should provide please reply and I can provide it! I don't know what else to try.

    Go to the elevated command prompt.  Enter 'powercfg /batteryreport'. Then return to the desktop. Open file explorer. Then search for' battery-report.html' in the c:\windows\system32\ sub-folder. Double-click to open it in the browser. Compare design capacity with full charge capacity and charging/nocharging history. Post screenshot if possible. Check also the battery re-set button in line with the pinhole may have failed.Jack E/NJ

    Hi Jack, thanks for the reply.

    Below you can find screenshots of the full battery report.
    When I did the battery reset with the pinhole on the back, I remember pressing until I actually heard/felt the button inside being pressed down and held it firmly, so I'm pretty sure it was working when I pressed it.

    ----------------

    I forgot to mention: right when I first installed the new battery a few weeks ago, the battery icon on the taskbar was showing "no battery is detected" / "no battery present". This stopped after I tried using the battery reset button and deleting the battery/AC drivers. It then would display the battery normally charging.

    Also, this morning the owner of the laptop brought it to me because it wasn't booting (or that's what it looked like). It would turn on only the backlight for the display and nothing else. I fixed this by unplugging it and holding the power button for 30sec and also plugging it into a HDMI display. Once I did this the laptop turned on and the display stayed on the laptop screen (not the HDMI that I plugged in). It hasn't done that again since.

    Since earlier when I made the original post, I had turned the laptop off for a while and now when I checked here and turned it back on it is back to saying "no battery is detected" on the icon (which it wasn't this morning after fixing it)...

    ---------------

    Sorry if this post is a bit hard to read, I tried to make it as understandable as possible, lol. I really can't seem to figure out what is happening here. 

    Thanks

    Yes. This is a springloaded normally-closed switch. The problem is that I don't think it's always normally-closed when released. That is, it's definitely open when depressed but sometimes stays open when released. An intermittent thing. Perhaps depressing it with your fingernail, then sliding your fingernail off the button to let it snap back to the closed position a few times will help clean its contacts to keep the battery connected.

    Before I take apart the laptop, I just want to make sure we're talking about the same button. 
    We are referring to the pinhole button for "battery reset" right? Not the "power interrupt" switch inside near the RAM slots and HDD. Thanks!

    Yes. The button that's in line with the battery reset pinhole on the bottom cover. The pinhole may actually be big enough to depress with a paperclip, then slide the clip off the button so it snaps back up. Or try a stiff wire thinner than a paperclip to try to avoid taking it apart again. Jack E/NJ

    I have attached a video file for you to see. I am not sure exactly what else I am supposed to do. The button seems to be working completely fine, make sure you turn on the audio and you will be able to hear, especially near the end of the video.

    Sorry for the confusion, thank you for continuing to help.

    Sorry I'm unable to download the compressed file. Can you verify switch continuity/discontinuity with a multimeter? Jack E/NJ

    I have posted the video unlisted on YouTube, hopefully you can see it there

    I'm not sure I would be able to do that since I don't own a multimeter and wouldn't really know how to operate it. If that is the ONLY option for fixing the laptop I can ask a few of my friends if they would be able to lend me a multimeter and try to figure it out but other options would be perhaps more optimal at this time.

    OK. Got the youtube video. Seems like you can easily make the button snap back up by manipulating the wire without pulling the back off. I gonna suggest simply playing with it like that for a while. Make the button snap back up a few dozen times for good measure. Then plug the charger back in. Wait for the charge  LED to turn blue. Turn the machine on. Pull the plug again. Jack E/NJ

    Hey Jack, I fidgeted with the button for about an hour and half for good measure, pressing it for short and long presses as well as trying to move it around like side to side, etc. After this, plugged in the laptop and let it charge fully. Once I turned it on it worked and came to the windows lock screen but once again shut down immediately once I unplugged the charger from the laptop.

    F2 into the BIOS menu. Pull the plug. Same thing? Jack E/NJ

    I went into the BIOS menu and pulled the plug, shut down immediately. Same as usual.

    Well, it's possible the battery has developed an internal resistance such that it simply can't deliver the current needed to keep the laptop on. It might be worth a shot trying a replacement battery, less than $30. Just google 'e5-774g' and 'battery' for vendors. You can also google the ACER part numbers shown in the link below but they may be pricier. Jack E/NJ
