Hi everyone. I'm new here, and I really need help in fixing my sister's Acer Nitro 5 (AN515-52).
Okay basically I opened up her laptop to clean the fans inside. The last time it has been opened was when we bought it at the pc shop, so it's been a full year or so since it's been opened up. I did my usual cleanup and only removed the fans to clean them. I have done this multiple times on my own Nitro 5.(difference is mine is the I5-7300HQ) and haven't had any problems with mine after each cleaning, so I assumed everything would be back to normal once I finished. However after putting everything back together and powered on the laptop, only the backlight of the keyboards lit up and the power indicator, but the screen remained permanently black.
I have done everything I can think of to fix this. I have tried the battery reset pinhole, removing the SSD, HDD and both RAM sticks, unplugging then plugging back the video cable, removing the battery and reinserting it, but none of them have worked. The laptop only powers on with a backlit keyboard and a black screw. I tried connecting the laptop to an external monitor and even our TV, but nothing would be displayed. It won't even display the BIOS at all after removing the Ssd and Hdd, so I'm guessing it's not na LCD or screen problem. I'm also not sure if it's actually booting up as I can't hear any thing after powering it on. It does give off a beep however when I plug in the AC charger and unplug it.
What is also odd however is that I noticed the cores and the GPU heats up significantly (or whatevers under the heat sink) a few minutes after I leave it on.
Is this a motherboard problem? Or is this some minor hardware problem (E.g. Loose wires/cables) that I may have overlooked?
I really appreciate anytime given to help solve my problem. My sisters using my laptop in the mean time while I'm trying to fix hers, but she really needs it for her work.
