Acer Predator 15 G9-591-70VM not turning on, how can I resolve this?

OK. Good. Like I said earlier, now search for a small spring-loaded normally off switch. It's sometimes located on the mainboard near the memory module slots. There'd also be a molded protrusion or pimple inside the bottom cover aligned with this switch that is designed to push against it to keep it the 'on' state when the cover is properly assembled. If the cover is slightly misaligned or not pressing hard enough against the switch, it'll unexpectedly cut power to the mainboard when the laptop is physically disturbed or moved. Jack E/NJ

This is the exact location of the switch button, which Mr Jacke refers to:

Hello,

I just wanted to say thank you for helping me out with my laptop, I really appreciate the it. I finally got the electrical tape to apply to the load spring, and it worked. I wanted to share some photos showing that the load spring is easily accessible by removing the hard drive cover, and not the entire back cover. And all you have to do is apply the tape over a section of the back cover that presses it. Hopefully these pics will be helpful to someone else.

Thank you again.

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. Post screenshot if possible. Jack E/NJ

Thank you for your response to this matter. Unfortunately, the current issue is that the laptop will not power on at all.
When I press the power button, the only thing that happens is that the red light for the power button comes on, and the tiny red light under the "light bulb" icon. Nothing else happens, no sound or anything.

OK. Try this. Press and hold power button to extinguish all lights. Unplug the charger. Rapidly but gently insert & withdraw a paper clip from the battery reset pinhole a dozen or so times to try to clean the contacts on the spring-loaded normally-on reset switch. Plug the charger back in. Hope for the best. Then press the power button. Jack E/NJ

Thank you for that. I realised that with the laptop plugged in, the orange light under the Battery icon comes on along with the red light under the Light Bulb and the red light on the power button. However, still no light under what I believe is the Hard-drive icon. Nor any fan noise like it is starting up.

I also just noticed that with the laptop off, I plugged in the charger, but it took some moving around of the laptop for the orange light to coming on and show that the laptop is charging. It was the same way I had to move it around until I found a spot on the bed that the laptop would start up, when it was shutting off suddenly. I assume it has to be completely levelled or something.

OK. This certainly sounds like there may yet be another spring-loaded normally-OFF safety switch on the mainboard that is either slightly misaligned with or not being pressed hard enough by a plastic protrusion inside the bottom cover. The protrusion is supposed to keep the switch ON and mainboard powered when properly assembled. You must remove the bottom cover to check for the switch or the case protrusion. The fix is usually by taping a spacer on the cover protrusion or switch button so it presses harder against the switch to keep it turned ON. Jack E/NJ

Hello JackE,

I finally got around to opening up the laptop. I changed the CR2032 battery and it finally turned on, whilst plugged in. However, when I plugged out the charger and tried turning it on, it would not turn on. None of the lights came on this time. Could it still be the 'protrusion' that you mentioned in your previous response? Or maybe I need to change the laptop battery? Although the Acer Care Center application claims that the battery is 'good.'
If you believe it is still the protrusion, do you have a photo or video that I could follow to find it and apply the spacer as needed.I look forward to your suggestions and thank you for your help.

If it still turns on with charger plugged in then the battery is suspect despite the ACER care center app. Try this. 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.

Hi
Sorry for the delayed reply. Had a busy few weeks, and my work computer, Acer Aspire v3-571 was giving trouble where the power keeps chipping in and out when it is nearly finished charging. As for the Predator, I did the battery report as requested, hopefully it will attach. I did manage to turn it on without it being plugged in, but it had to sit in a specific on the desk it seemed. I am guessing where specific portion of the base has to sit on the desk and not hanging off. Before I was trying to power it on while on the bed. I guess the surface was not even enough.

OK. The MS battery report agrees with the ACER CareCtr report that the battery seems to be OK. So from your description, it sures sounds like the safety switch is cutting power to the mainboard --- or the power button board is faulty or its cable not fully seated to its mainboard connector. Unfortunately, I haven't yet been able to find exactly where the safety switch is located on the G9's mainboard in my documentation. It should be a small spring-loaded normally off switch sometimes located on the mainboard near the memory module slots. A protrusion or pimple molded inside the bottom cover is designed to push against this safety switch into the 'on' state when the cover is properly assembled. If the cover is slightly misaligned or not pressing hard enough against the switch, it'll unexpectedly cut power to the mainboard in the fashion you describe. Whether the switch or the power board, it means disassembling the laptop to get full access to the mainboard. Not a trivial job but I can try to walk you thru it if you're game. Jack E/ NJ

Yeah, I am up for it. Hopefully it won't be more than lifting off the back cover again to find it

OK. First remove the HDD & RAM door. Then remove the HDD & m.2 card. Then remove 17 screws as shown below. Then use a credit card (or a putty knife for a stubborn case) to pry the bottom cover off. You will probably break a few plastic catches but nothing that the 17 (or fewer) screws & color-coordinated duct tape can't handle when putting it all back together again. GO! Jack E/NJ

OK, I can do that. What will you need me to do next?

OK, and to be certain, this would not be the same button that I would use to "bleed out" the battery through the pin hole, right?

This is the exact location of the switch button, which Mr Jacke refers to:

@Sambatraube Follow this topic too!

Correct, it is not the battery reset button. If you find a switch like that which egydiocoelho encircled in black, that would likely be the safety switch. Jack E/NJ

OK awesome, thank you guys. What would be the best thing to place on it to apply the necessary pressure? Will a piece of folded paper be suitable?
