Model:Aspire E5-475G-55DU
Issue:
Wenever I press the power button to boot up my laptop, the power indicator flashes blue light every 5 seconds. During each flash, the heatsink fan briefly spins and then stops. The display doesn't turn on, let alone show the Acer splash screen.
When the issue first appeared:
My laptop booted just fine before. But I had to replace the internal battery so my laptop can be used without needing the charger to be plugged in all the time. So I replaced the battery and while I'm at it, I cleaned (only) the heatsink area. After putting everything back and tried turning the laptop on, that's when the issue first occured, and up to now.
Measures I took:
I can verify that the replacement battery is compatible with my laptop model, so I guess concerns with the replacement battery are ruled out.
I tried putting back my old battery to see if the issue goes away. Unfortunately, the issue persists. But I guess that means that rules out any battery-related concerns.
I made sure to properly plug back in the peripherals I detached while doing the cleaning and replacement. (These are: speakers, heatsink, battery, RAM, and something that looks connected to the charger port.)
Question:
Do you guys know or at least have any clues/hints about solving this issue? Anybody else experiencing the same?
