My laptop has trouble staying on Aspire E5-576-392H

CrimsonKnight

So my laptop suddenly shuts off recently. Thinking battery died so I put it to charge and turn it back on, but the power button wasn't working (on keyboard). When I pressed random keys on the keyboard it would turn on and last a certain time before turning off again. (around 1-5 seconds on average). I finally got it on hence I'm typing this but the way I have it on makes my laptop unusable, I have a water-bottle (1.5L fulled) on top the keyboard because keeping a heavy object on the keyboard keeps it on (as well as spamming keys to keep it on). if I remove the water bottle it instantly shuts off and goes through the on and off process. I don't know if it is software or hardware problems but I hope I can receive some help here.

Things to note if it helps; I recently updated windows, downloaded a file that had a virus but it's removed don't know if it's still present, undervolted my i3-8130U -150mV and iGPU -110mV.

There are two springloaded switches on the motherboard located near the RAM socket. The switch closest the the RAM socket is a safety interlock switch that cuts all power to the mainboard if the bottom cover or door is not tight enough or misaligned  to keep the switch turned on. You can try tightening the screws on the bottom cover/doors so that they press harder against the switch. Sometimes spacer needs to be taped inside the bottom cover or door to press harder against this switch. Depending on your model, the safety switch could located on the left side of the RAM socket as well.

Hi @CrimsonKnight,

May I know the full model name of your unit.

It is Acer Aspire E5-576-392H @Easwar . Also I've figured out something, the key that must be held down for the laptop to stay on is the button G. Otherwise if I remove a heavy object from it or stop holding down the key, acer quick access asks if I want to shutdown and it would anyways. Could there be something on the board underneath the G key that's broken? Or could some software change it. Let me know thanks

@JackE I do not think that model has that switch on it I've looked near the RAM areas. Either that or its in the middle since thats where pressure is applied the laptop stays on but I am not comfortable opening up the entire laptop

Yes, the safety switch definitely could be located elsewhere but in the same general vicinity of the RAM socket. Simply try snugging up the base cover screws first instead going full bore and opening the laptop.
