Acer A5600U-UR11 will not boot. Black Screen. Unable to enter BIOS

I realize this is gravedigging a post, however, I wanted to inform others that come across this thread on possible solutions as I ran into this issue with a few of these specific models and wanted to power the solutions I have found to work for ALL of them thus far without resorting to shimming the GPU/CPU to increase contact or blind-flashing the BIOS.

The issue I am speaking about is the following: Turning the computer on the power light will illuminate, the screen will from pitch black then light grey (showing the backlight illuminates), however, the screen turns black and either the power light turns off after a few minutes or the power light stays on indefinitely.

This seems to relate to all sub-models of All-In-One A5600U and might even relate to all Acer All-In-One models after 2012 but I have no way to confirm. To some folks who are a bit versed in IT some of the solutions might seem trivial, but if you really HAVEN'T attempted them I suggest you try.

Solution 1: Power discharge

1. With the power light off, unplug the power cord from the computer (or wall, or cord from the wart whichever is easiest to access)
2. Hold the power button for 10 seconds.
3. Plug the cord back in and turn it back on to see if issue changes.

Solution 2: Rule out peripherals

1. With the power light off, unplug everything except the power. (Yes, the keyboard, mouse, externals speakers, anything.)
2. Turn the computer on, with your items unplugged, and see if the issue changes.

Solution 3: Reset BIOS Settings (most common solution)

1. With the power light off, plug the keyboard back in (so now all that is plugged in is the power and keyboard)
2. Press-and-hold F10 then turn on the power.
3. Continue to hold F10 then after 30 seconds you should hear 2 loud beeps and a screen with white text should appear confirming the BIOS reset.
4. Release F10 then press F1 to continue boot.

Solution 4: Reset CMOS

This solution requires taking off a panel on the computer and moving a part called a jumper, if you are uncomfortable with doing this or have no idea what this is I suggest you take it to a technician and let them know what you have tried thus far because I will not go into specifics below what a tech should already know.

1. Lay the computer flat on its screen with the kickstand bottom facing you.
2. Along the 'bump' past the kickstand looking from bottom to top, where the power, USB devices, HDMI and other ports are, you should see 2 screws on either side. (if you see more than 2 screws, you might be looking at the very bottom which is not correct).
   1. Remove the 2 screws
3. Place your thumbs firmly on top of the left and right edges of this cover and pull down, it should slide but stop.
4. Use your fingers to gently pry the cover toward you, being careful not to yank as there are plastic tabs that hold it in place. It should require almost no force at all.
5. Near the hard drive (top right) you will see the CMOS jumper. Move the jumper from 0 to 1.
6. Plug in power, press and hold power button for 10 seconds.
7. Move the jumper back and power on again to check if issue is resolved.

There are other solutions online that are more complex, which you may feel free to look up.
