I purchased an Acer Aspire E5-473G-51GY in March 2016. I took it to Acer to have new RAM put in it after buying it, so I wouldn't void the warranty by doing it myself. They told me it didn't work. I went ahead and put it in myself in September, and it worked. The problem is now a few months later while watching a YouTube video, my laptop suddenly froze. I did a forced reset with the power button. When the laptop turned on, it just showed a black screen with no option to go to the BIOS menu or any logos, just black. The fan makes noises, but no beep from the motherboard.
I went through basic troubleshooting. Plugging it into an external monitor. Taking out the battery and holding the power button. Taking out the hard drive, which resulted in it turning itself off immediately (I was also able to use it in a different laptop) Normally it will stay on until I press the power button. Then I tried taking out the new RAM. Then I tried leaving the new ram and taking the original one out. Then I tried RAM from a different computer. I tried using different RAM slots. I inspected all the wiring and ports and nothing looks bad expect for very slight discoloration on the motherboard port to the laptop's monitor. But I would assume if that was the issue, the external monitor would have worked because it is a different port.
After doing this, I googled the issue. I found two tips. One was taking out the CMOS battery, which is possible because it is soldered. I can solder, but I feel like that is still risky unless totally necessary. Another person left theirs on for a while and it sorted itself out somehow. I tried that, but it still hasn't changed anything.
What other suggestions would you have that I haven't already tried? Taking to Acer isn't necessarily possible now that the warranty has been voided. I'm afraid that will cost way too much.
